Amazing documentary. All this makes me wanna live billions years, just to see all those events happen. Discovering new life, first time human colonise new planet, etc. Will human last for millions years ? Billions years ? Will human spread into space, even see our own sun dissapear ? How far will we go into nature comprehending ? That's really fascinating ! That's unfortunate that we happen to live for such a short period of time.
When will our fine scientific minds "scientists", make up their minds. It seems every decade or so old theories die off and new one's emerge. Come on guys ,no disrespect, but it's gotta be a higher power.
The very nature of science is about learning and acquiring knowledge. Sometimes this means evaluating older data compared to newer, and revising our thinking. Some people want all the answers right away and unchanging. Religion provides that for the most part, in a tidy package.
Science is rougher and takes more than faith. You must be prepared to peer into the darkness and have the courage to say "I don't know... yet."
@jojo123469 If you think you can do any better, why don't you try being a scientist & share your findings? That's right, it's more difficult than you make it out to be, the nature of the universe is too complex for us to have figured everything out about it in our incredibly short time on our planet, we may get there eventually, but it's the marathon of all marathons, and you're expecting a sprint, & just because we haven't figured something out yet, doesn't make it a higher power.
@jojo123469 Old hypotheses die off if new evidence emerges to refute or refine them. A theory in the scientific sense is a body of demonstrable, testable facts. You use theory here to mean something which has no evidence and is essentially a priori assumption such as thinking a god exists with no discernible evidence. Where scientific theories are a posteriori justifications based on experience.
@Zapachna6661 I respected your first comment which made much sense, However your second one is a bit out of line. A theory is or can be an explanation that has not been proven by hard facts. If anyone can tell me what was there before the big bang I would love to know. I also know that a man named jesus did exist but was he who he claimed to be, there is your theory.
I got it , no disrespect to our fine scientific minds, could we ever put a giant propulsion engine rigged to our earth and just use it as a mother ship to travel the universe. Wow I'd love to see that . Hey you never know.
Their Talking Like its Going To be Such a Scary Thing When The Andromada and Our Milkyway Collide in 3 BILLION YRS?- SURE!~>we,ll Be LONG-GONE By That Time~ we,ll Be Lucky To Live Another 100 Yrs! before We Either NUKE ourselfs out of Existance or Become Exstinct By an Asteroid or Comet!..Another Thing~>They call IT OUR" Galaxy?..Like as if A 125 Million Light YR, LONG Galaxy was made Just For us? SERIOUSLY?~> We are Just a Temporary Virus~ I Love Life But SOON-->We Will Be GONE!~> 4EVER,
if Any Object in the Entire Universe Could be (LOVE??)-> it Would Have To Be All The Black Holes!!!..Because Once you Get Too Close?? your All DONE!!!--> you,ll Be SUCKED INTO-> The LOVE-HOLE!!!. NEVER TO BE FREE AGAIN!!!~O:" HELLLLPPP!!!!!!!!??
The narration in this sucks and is dumbed down tho the level of 8th grade - so it can be understood by the average american and has that added thrill of classical music to make it seem sophisticated. An obviously American product.
Reminds me of " Tomorrow Land " and even more that we got the Simpsons instead of the Jetsons.
@knowmehuh Look lady, it's a parody on the annoying accent that the narrator has in this program, it's very grating after only a few minutes viewing. I made the post as a way of telling MsNimpnimp that I agree with her own view above. I speak, read and write English, German, and Danish - German fluently, I graduated from a German acting school. While we're on topic, "Son" in your own sentence isn't supposed to be capitalized, and a comma shoud precede it; you'd best work on your own mistakes.
@vrikey lol why confess this much mayne?? I mean I wrote son as Son coz i wanted to magnify how a hood dude u might be lol okay thanks for correcting me. I speak lil German too. Warst du einmal in Deutschland und warum hast du Deutsch sprache gelernt. Bist du ein Deutsche? also ich bin ein Jungermann nicht lady haha. Alles klar!
@MsNimpnimp Is it just me or does he sound like a Bond villain or Palpatine or something? He sounds like he wants to conquer the galaxy more than anything lol
Just another dummy here enjoying the comments as much as the video-2 minds in cyberspace exchanging ideas and beliefs .now my 2cents........\m/ rock on
Science is the new secular authority. Scientists the new rational diviners of our reality and existence, our truth, like priests were the old spiritual diviners of our truth. When either make statements that don't match our experience of reality we shouldn't just bow our heads and baaah at them in acquiescence and obedience- we should question them, and if they don't have the answers they shouldn't have our obedience. They are not an undeniable authority. They are not a church.
thats a bit of a stretch to say Science is the new secular authority, obviously the main difference being EVIDENCE.....however, I agree Science is limited and it may not be the best path for discovering truth(whatever that is), but so far its the best we've come up with .....without science there wold be no quantum physics, and it seems to me that furthering quantum theroy can only lead to good things for mankind...
@63Bueno Indeed. I'm all for progress, thats why I don't like it when we seem to arrive at a point where even though we appear to be wrong about some things, we are unwilling to change our minds. How once we have set our own personal, individual world view, we don't like it being disturbed. I can't validate or refute any mysteries- but I was never trying to. What I wanted to illustrate to someone, who hasn't been commenting on this video, is a few fundamental truths about human nature.
@63Bueno Human truth is far easier to understand than the universe, easier to study. U spend every day surrounded by people and then there is yourself also- if u haven't come to some understanding of basic human nature, human truth, that should be your next field of study. Science is a double-edged sword. Without science there wouldn't be guns, nuclear weapons/waste, pollution, carbon footprints, deforestation or oil spills either, so as great as it is it comes at a price.
what the hell are u talking about?? If u want to talk about not knowing real truth, HUMANS are something that is far stranger than the universe...are u kidding?? I mean, consciousness is the biggest mystery of the universe as far as I'm concerned..What is this thought? Imagination? What is dreaming? To say u know what human truth is, is an overstatement to say the least..
@63Bueno err, I think u have misinterpreted that somewhat! So u have absolutely no idea at all what is going on in your own mind at any time? U have no understanding of your emotional and psychological state and resulting behaviours? There is a huge difference between knowing what something is doing and knowing how it came to be able to do it. Like me typing via computer, I know how to do it but how all those silicon transistors actually make it all possible is a little beyond me.
I suggest u look into quantum physics if want to see just how strange the human mind can actually be..it turns out, the mere act of whether or not a human mind observing a particle, deteremines whether that particle acts as a particle or a wave...quantum entanglement(when 2 particles entangle) shows that one particle affects the other INSTANTANEOUSLY correlationally no matter the distance.this is probably the explanation for twins being able to sense other's pain immediately..
@63Bueno The whole point of this epic talk was to illustrate just how little we really know and how we have trouble accepting that fact quite often as it detracts from our sense of control, which of course is an illusion anyway. Spend some more time experiencing things directly, observing, rather than scientifically disassembling them to their constituent parts. I know how strange the human mind can be-
@63Bueno I have seen and experienced it for myself my entire life and know how it works, though I may not know how it is able to do the things it does from a diagnostic point-of-view, I still know that it does them.
@63Bueno I don't require QP to know how strange the mind is, it is obvious from the experience of life. As complicated as it is, it still adheres to certain truths- I have just been able to predict your behaviour and responses (or a similar persons) based on no empirical evidence, theories or equations- I just used my own mind and knowledge of how it works, my experience and an innate sense and knowledge I have gained from living my own life, being thoughtful and observant.
@63Bueno I started off with the premise that no matter what argument, or how valid, was put across a certain type of person would never concede that there is a possibility of what they presume to know being incorrect once they have let their mind settle on certain 'truths' about their existence, our knowledge of it and what respected (chosen) authority authenticates it for them- they become rigid, mentally. We are all guilty of that mentality to varying degrees. Just look at religion.
Over the course of time we've been told the Earth hatched from an egg, or sprung from the body of a god, or resulted from a singularity, etc. Let's be realistic here. Most people don't give a shit, whatever the case may be. It's something to study for a test, or acknowledge in casual conversation until the Next Big Discovery arrives. We could blab on Youtube all day long about how nothing is perfect or true, but we probably get less done than a real researcher.
@dunnono00 Yes, we never seem to learn that todays knowledge is different to yesterdays and will be different to tomorrows, we always seem to think that where we are now is the pinnacle- which is most informative about human nature, not the universe, the mind, god or anything else. The truth is that we are extremely conceited and have a little too much pride in ourselves and our status. Many people don't care or think much, but they still like to have immovable opinions about it all.
@dunnono00 They will enter into arguments about things they cannot be sure of. Disparage other people for their ideas or beliefs that they cannot themselves confirm or refute in any meaningful way. They try to impress upon other people their own personal views and take offence if they are not well received, while simultaneously refusing to see anothers point of view. Thats humans for u...and kinda glad I didn't go to your school! We were never taught that Earth hatched from an egg!!
@dunnono00 But we should never defer our right to think for ourselves to any single person or group of people. Blabbing in the right way is no bad thing, although if u are happy to behave like cattle and just accept what someone tells u without ever thinking about it for yourself, I hope u can be equally happy when that inevitably leads to u being treated like cattle.
Of course, when we acknowledge research by people who invest their life into it, we shall become cattle. Except for TheSoulDoubt, who by his Youtube commentating, has been set free from the shackles of the world. While we are mooing in our pens, you shall be freely mooing on Youtube.
@dunnono00 lol, yeah nice try! I have invested my life into researching human behaviour, so do u want to contradict yourself some more or dig yourself a little deeper? People who 'don't give a shit', as u so eloquently put it, tend to be the ones who spend their lives being lead by others- so which are u?...or do u need someone else to tell u?
@dunnono00 Yes. It comprises of an entire 28 volumes of work contained in 28 paragraphs on a single video, just for your convenience. It is a complete and concise collection of a lifetimes work and study condensed into several rudimentary sentences per volume, so that people who relate to video game characters more than living things have the capacity to absorb it in an Easy-Read format.
U want to get into any other things we really don't know but like to pretend we do? Howabout the Big Bang- in a universe governed by causality in every single way, which is what makes all the Darks a necessity for our understanding- the universe spontaneously created out of an infinitely small and dense...'thing', that we call a singularity, for absolutely no reason whatsoever. Everything from nothing for no reason at all. The diametric opposite of causality. Dark your way out of that puzzle?
Dark means 'don't really know whats going on'. But as Dark is currently propping up, as in stopping them from collapsing (so Dark is more of a simulated scaffold structure to hold our ego and pride up as much as the universe), so much previous scientific work and theories scientists find it conflicts with their sense of pride to say 'don't really know whats going on'. So they adopt a more fancy name that gives the impression that they do know whats going on so they can still sound scientific.
A quote, just for u, on what the widely accepted...sorry, meant to say undeniable, scientific status of referring to something as Dark really means: " It has been noted that the names "dark matter" and "dark energy" serve mainly as expressions of human ignorance, much like the marking of early maps with "terra incognita"
OK, Im am a uneducated 29y old M. I have no HS Diploma! I do Understand these theorys. Dark matter must also be in Sub Atomic particles because there are things about their mass that I also question. What keeps the N and the P from flying apart? What Makes A planet Orbit? Is the Center Of these planets or stars spinning? And what is a moon all about? I got a dark Matter tattoo today:)
Space expands faster over time- in 5bn years the universe should be more than a third as large again- so are they speeding up/slowing down and how come, if we are so certain of things like expansion rate, orbits, gravity, distance, speed, etc, there is a margin of error of 2bn years on an object we can see clearly, determine the distance of so accurately, its speed and trajectory and have such a good understanding of how fast space is expanding!?
The start of this chat was asking how astronomers can be sure of cosmic distances, not what the correlation between lights age, speed and distance covered was. And the reason for that was because Andromeda colliding with the Milky Way in 3-5bn years seems strange. Space is expanding rapidly and can exceed light-speed. The universe has, apparently, grown to be at least 14500mpc across in just 13.7bn years, and as objects grow more distant the effect of gravity weakens...
Question: Where does all the color come from? is that how a nebula would look with the naked eye? All colorful from star light exposing the gases? Or is that how they make it look..?
dark matter... light passes through it.. hmm. why? what a crock dark matter exists as much as moses turned water in to blood .. utter bollox. its called poor math. or rather incorrect math.
There can be no edge of the universe if space is uniform in all directions, so its size and age cannot be determined. If it isn't uniform in all directions, theres an edge, then our galaxy at 12bn years old should be closer to an 'edge' than a 'centre', so when we look into space we should notice a distinct lower density of objects in the 'edge' direction to the 'centre' direction. If direction is irrelevant, then our estimations at the dimensional extents of the universe are invalid...surely!?!
@andielines er...ok, thanks, not heard of it and thunderbolts kinda sounds more like a nightclub venue than an academic venue developing theoretical explanations! DM and DE, String and Brane Theory have all put me off somewhat listening to further hyperbole from 'scientists' who insist upon empirical evidence when it suits them, then disregard it to promote their own ideas or views. None of these things have a shred of evidence to support them, they are just mathematical constructs.
@andielines Maths is a language, a very precise descriptive language, but then so is English when used correctly and I'm sure, like all languages, it has scope for creative use when applied and manipulated in the right way. String Theory has 5 different versions which proves that u can contrive maths to get the answer (description) u want almost in the same way as u can words.
@TheSoulDoubt You've made an error--you said "space is uniform in all directions", but how do you know this? The only 2 ways you could know this is if you either traveled to the edge of our universe and actually saw what happens to space at the edge, or studied the calculations of the cosmological beginnings of our universe as it expanded which invites the question: what was it expanding in? Truth is neither you nor I knows if space is uniform at the edge.
@PenthouseDiaries I quoted from many different astronomers from several sources that space appears to be uniform in all directions which they base on the Hubble ultra-deep field observations- so no, I don't know this at all and as u state neither really does anyone else which is why I question some of the presumptions made about our universe. Conceptually, what is an edge? If it is an edge in 4-dimensions the word doesn't really mean anything to us because it is beyond our ability to perceive.
@PenthouseDiaries Aren't blackholes dimension-less? They are the opposite of dimensional existence. Imagine what happens to light when it is emitted from an object inside the event-horizon in an outward direction. Does that light travel any distance before it is bent back on itself down the singularity, or is it instantaneous- does that outward direction still exist? Nothing can travel in that direction anymore, so travelling in those conditions is instantaneous, u can never backtrack at all
@PenthouseDiaries So where u started is always exactly where u are and u are immediately at the end of your journey without actually moving anywhere- the idea behind wormholes. Blackholes are the end of our dimensional existence as far as we can tell. Thats why we don't really understand them or the (supposed) origins of the universe. Singularities don't obey our laws. Gravity, time and space all go to SHIT in them!
@PenthouseDiaries If anything they appear 1-dimensional...or even 0-dimensional. there is only one way to go once u cross the event-horizon- into the singularity, instantly.
@PenthouseDiaries If not then for it to be an edge in 3-dimensions obviously it cannot be uniform otherwise it wouldn't be an edge. Like the edge of a cliff is not uniform- one way is a 300ft drop the other way is level land, if this isn't the case it isn't an edge. I'm sure I read somewhere that the best hypothesis for the universes shape at the moment is toroidal, which involves extra dimensions which then renders most of what we can think about the universal size, shape and its edge obsolete.
So how do we come up with the dimensions of the universe or its age? We look at red-shift in light from distant, ancient objects. How fast they are moving away from us...but our galaxy is an ancient object (and space is uniform in all directions), so if we travel to an object at the edge of the visible universe 60bn light years away and continued to look in the same direction as we had travelled, would we see the same uniform density of objects and another one 60bn light years away?
If this isn't the case, the expansion of space makes the idea of something being somehow central irrelevant, how can the size of the universe, or its age, or even the Big Bang be accurate? If there is no such things as a central starting point, no difference in any direction, how can things like time and distance be established? If u can't ascertain where something started from, u can't ascertain how long its taken to get where it is or how far its gone-
@TheSoulDoubt "If there is no such things as a central starting point, no difference in any direction, how can things like time and distance be established?" (1) No starting point = Isotropy. (2) Everywhere seems the same on grand scale = Homogeneity. 2 basic principle of the Λ-CDM cosmology and the Big Bang (ΛCDM is an abbreviation for Lambda-Cold Dark Matter), based on the cosmological principle.
sure u can...u just rewind the clock using the laws of physics...u can measure light by its speed(186.000 miles per second), so u can use that to then determine how long it has taken to reach us, thus its age...
@63Bueno I'm sure there are very good methods for establishing these things for people to be so certain about them, but u can't do it just from knowing lights speed, u need more information than that. A car has just pulled up outside your house and it has been travelling at a constant velocity of 100kph- tell me how far it has travelled or where it started from or how long it took to get there with just that information alone? How do u determine lights age if u don't know when it was emitted?
@TheSoulDoubt Light from distant objects reaching us now was emitted, in some cases, before our planet even existed- so knowing its speed does not tell u how far it has travelled and its age. Doppler effect (as far as I understand it) determines that an object is moving away or towards u, red or blue-shift, but again not how long it has travelled (hence distance travelled also) unless u already know its time of origin.
Light always travels the same speed...Scientists are able to determine a stars distance by all sorts of various methods depending upon how far it is...They use the term "light year"(how far light travels in a year which is 6 trillion miles) to describe how far away these stars are since the speed of light is constant....Our nearest star is 4 light years away(24 trillions miles)....the observable universe(just what we can see with our modern telescopes) is 13 BILLION LIGHT YEARS
@63Bueno How much further than Hubble do you think the James Webb telescope will be able to see? I think it's suppose to sit 1 million miles from Earth? (I think, if I remember correctly.) How far away is Hubble?
we will NEVER be able to see beyond what we see today with telescopes....all galaxies outside 13 billion light years away are rushing away from us(and everything) FASTER than the speed of light, which means their light will never reach us...
yes....if we were to be in one of those galaxies on the edge of our visible universe. then our Milky Way would be on the brink of saying its final goodbye as its expansion away would outrace its photons(what light is made of)
@63Bueno Yes, I understand that light-speed in a vacuum is a constant- celeritas, as its referred to often, however that does not, as far as I can see, inform u how far away something is. Photons are arriving here constantly from these objects whether 4 ly away or 13bn, how do scientists tell when the photons left the object and hence how far away they are?
@63Bueno Light speed was determined by timing how long it takes light to reach a destination from the time it is emiited- like turning a torch on and then seeing how long its light takes to reach somewhere. Stars and galaxies have been emitting light constantly since before we were able to time how fast its travelling, so when we observe an object that is so distant how do we know when the photons arriving here now left the object and how long they have been travelling for?
by determining how far away the object omitting light is..duh! u just said it yourself. light moves at a constant speed, so its distance is directly correlated to its age..
@63Bueno omg how many times do I have to say the same thing- knowing lights speed does NOT tell u when it started travelling and therefore does NOT tell u how old it is and hence does NOT tell u how far it has travelled. What are these other methods is what I have been asking, do u know? Keep the duh for yourself until u can actually correctly read and interpret what is written please :)
they dont use the photons to determine distance, they use other methods,and then use lights constant speed correspondingly, u seem to have it backwards..
@63Bueno Is it interstellar triangulation? Although I am finding it hard to see how that would work as all bodies in space are in motion, so technically there are no fixed points of reference with constant angles to be determined.
@63Bueno Don't worry about, it found my answer. Radar in the solar system. Parallax for nearby stars. Cepheids in our galaxy. Supernovae for other galaxies. Redshift for very distant objects.
...and, surprise surprise, none (except redshift which is still only based on Hubbles theory and not, at this time, factual) of the methods used have anything to do with light travelling at a constant speed of 186,000mph!
i never said the methods had anythingto do with light speed..all i stated is that they found the distance using various methods(u just stated those various methods) and then used light's constant speed to get its age....we know our galaxy is one of the very early galaxies, so I would assume that since we are basically as old as the universe, light speed would correlate very well to determining lights age in the universe for us...
@63Bueno lol...typo! ;) Yes, and Andromeda is about the same age as the Milky Way, so we've been in proximity since nearly the beginning in, what was, a far smaller space, so we should have been closer together, caught in same orbit, whatever. So if we haven't collided already in all that time- how come we will in 3-5 billion years when we will be so much further away from each other than we were at the start?
we are CLOSER to Andromeda now then when we both first formed 12 billion years ago if u relate it to the expansion of the universe as well....not sure how far apart we started but undersand we are only 2.5 million light years from Andromeda and it will be another 3 BILLION years before we collide....the speed with which the two galazies are moving towars each other is not very fast...
@63Bueno Just been looking at info about speeds, clusters, superclusters, Hubbles Constant, planes, The Great Attractor and more and it all lead me to Dark Flow. Everything moving towards a sibling universe (?) or an area of spacetime fundamentally different to our own (???) outside observable limits...which is where I get off!
@63Bueno So if u add all the Darks together, Energy, Matter and Flow u get EMF- which stands for Electro-Magnetic Fuck-up...which is appropriate because we can't see or detect any of it!! ;)
whos claiming to know what is goin on in the grander scheme of things? thats exactly why they refer to it as dark energy and dark matter, they havent a clue, thats what the dark mean as u stated....obviously we only understand an incredibly small fraction of this life.. but just think of the exponential rate of technology and discovery, its possible in our lifetimes we will know much more, but there of course will always be more, its a never ending process...
but u are wrong on one thing....we CAN detect dark energy and dark matter, by their gravitational presence...obviously we cant see it yet, it doesn't interact with light like regular matter does
@63Bueno No, that is an assumption based on general relativity being the complete picture of gravity. We infer there existence by first assuming relativity is entirely correct then making-up other invisible 'matter' to compensate for a lack of apparent mass in the universe according to relativistic effects. Hey, u know what, I don't interact with god the way the pope does so is that why I can't see Him?
@63Bueno How so when general relativity gives us our best understanding of how gravitation works by curvature of spacetime, so anything exhibiting gravitational effects is dealt with through that theory- it only bends light because (if?) it is some form of invisible matter curving spacetime in accordance with relativity, obeying its laws. Without general relativity it wouldn't even (be presumed to) exist!
@63Bueno U said it yourself, without DM there wouldn't be enough mass to hold galaxies together, they would fly apart- thats what relativity tells us should happen with the amount of observable matter and mass. Without DM curving spacetime, keeping cluster structures together and bending light in its spare time, everything would fly apart, relativity and expansion say so...so how do they have more than general relativity to back it up?
u said there is no way we can see the dark matter, that its just based on purely relativity being correct...then why can we SEE bent light where there is no observable mass to bend it?? because mass of another kind is bending it, the dark matter...
they have supercomputers that construct galaxies based on relativity. these galaxies just dont form with normal relativity as one would suspect but when right amount of dark matter is added they look EXACTY like a spiral galaxy
@Bueno63 Good morning. Gravitational lensing has been seen round clusters where there is not enough 'supposed' mass to bend light in such a way, which is based on relativistic calculations- the same ones put into those supercomputers so they would give the right formations. It only happens where there is visible mass, just not enough to have the effect relativity states should be present, so therefore we infer it must be Dark. Inferring is not evidence.
@63Bueno We have been running extremely sophisticated simulations on supercomputers for many different things for years, like the weather- but we find computers can only simulate information we are able to provide them with because last time I looked computers weren't actually creating reality off their own backs- that was just a film called the Matrix I'm pretty sure.
@63Bueno Weather is only relative to this planet and we have far better access to all the necessary information and variables that contribute towards weather and really should understand the systems involved much better as we have far more experience of them, they are right here with us every single day and have been for 10,000 years, we can see them and touch them and interact with them and yet they still can't quite get predictions or simulations of weather right can they!
@63Bueno And I'm guessing that our weather here on this tiny little planet is not as complicated as the formation, structure and movement of the entire cosmos. It may well be real, but in 80 years no-one has found any physical evidence for it and THAT IS a problem. If we add Dark Matter to weather simulations maybe they'll be more accurate too....who knows?
@63Bueno What else can we add to our 'knowledge' of the universe that we only need an idea to support and then infer from- I noticed this morning that when I prayed the sun came out, does that mean weather is influenced by prayer? Anyway its obvious that my questions about your belief in Dark Matter disturb u somewhat and I didn't come here to disparage your faith or need and desire to believe. Just came for a look.
@63Bueno One last thing, Dark Matter has mass if its real or it serves no purpose and doesn't need to exist- it is presumed to have neutral charge and so doesn't interact with ordinary matter except via gravity, and it was separated from baryonic mass around the formation of the CMB so does not interact with radiation either, but its been around just as long and has mass and gravity- so why hasn't it formed into Dark Massive stars or blackholes when ordinary, lighter matter, has done so?
@63Bueno Why has it just remained as this bizarrely shaped floating structure threading through the universe- why, if it has so much mass and gravity and is unaffected by all the things ordinary matter is effected by, hasn't it/doesn't it coalesce into its own spherical structures like stars and planets? Why doesn't it collect into stars cores and collapse them by pushing their mass beyond a stable amount?
@63Bueno It can pass through anything, interacts with nothing- why is it just floating around in nondescript 'webs' that have no gravitational structure themselves and yet supposedly gives the entire universe ITS gravitational structure?
@63Bueno Theories based on other theories to keep previous theories working. Big Bang needs DM to work. Relativity needs DM to work. It could be real, I don't deny that- its just that I also don't deny that we could be WRONG, and as soon as we let arrogance and pride inflate our little minds to unrealistic proportions like the church did in Galileos time, we find it hard to accept that maybe we have got a few things WRONG, and thats what hinders progress most.
@63Bueno And we kid ourselves that we really know and understand whats going on in the greater scheme of things? That we are just a Higgs-Boson away from having a complete picture of everything? Seems like a bit of an unrealistic presumption when we don't actually know what 99% of existence actually is...well its Dark, we know that much...which is also appropriate because thats where we are- in the Dark.
@63Bueno Personally I think we still don't understand what 'gravity' really is...sorry Albert! Which is why we still have so much Dark obscuring our vision. They are all related to what we call 'gravity'...kinda makes more sense to say something is wrong with our theories about gravity and change them rather than completely changing perceptible reality across tens of thousands of megaparsecs and beyond so we don't have to alter the theories.
id say the theories are quite sound for the HUMAN observable universe at this point....it doesn't make sense to throw away all of our theories and search for the truth using dark matter and dark energy(the vast majority of the universe)...we know nothing about them, all we can do is measure their presence...i mean, we cant abandon everything we know because we just found out theres a whole lot more to the picture than frst imagined...u build off prior knowledge and move forward
@63Bueno And no doubt we will actually do that in a few years time when we take our heads out of our asses. At the moment we are not building on previous knowledge, we are randomly inventing our own reality to suit our needs and have rejected the empirical process to make our previous knowledge still apply as we encounter more and more contradictory observations to our theories predictions. That is not progress- its bordering on delusional.
@63Bueno Not saying we should throw anything or everything away, just reassess some very specific things as they just don't seem to work unless we add in our own magic fairy dust that really doesn't exist as far we can tell, it is simply suggested that it must be there if our theories are accurate...which they aren't according to known, observable reality, which is why we have the magic invisible ingredients. Thats borderline faith, not science.
@63Bueno We somehow arrived at the state of mind that we have discovered so much that we must just about know it all. More young people would probably get into science and astronomy and stop watching x-factor if they didn't keep getting told by all these shows that there isn't really anything left to discover, that we have figured it all out, that theres not much left to know.
@63Bueno We've come a long way, sure, but one thing we should have learned by now is that reality operates in unimaginable scales and we are probably at the tip of the iceberg with all the really big stuff hidden beneath the surface that we are barely scratching.
@63Bueno How can it possibly STILL be moving towards us when it has had 12bn years to reach us, needs another 3-5bn years to get here, and started heading our way in a relatively tiny universe where gravitation should have been far stronger? It doesn't make sense. And as revenge for pointing out my horrific lightspeed typo, light gets compressed or stretched into higher/lower wavelengths depending on whether an object is moving towards or away from us ;)
@63Bueno Its 1pc away now, so where was it 12 bn years ago when the universe was tiny compared to what it is now? If it takes another 3-5bn years to reach us that is a greater overall time than the (presumed) age of the universe! How is that possible when the space between us would have had the time to expand to the size of the entire universe as it is today which is around 14500mpc in any direction?
@63Bueno ...aaaand the expansion of space is supposedly speeding up aaaand can exceed lightspeed- how does anything collide over such huge timescales and distances in those conditions when the moving material objects cannot exceed lightspeed and they originated closer together at around the same time?!!
galaxies can collide over such vast distances because they are still bounded together by gravity....most galaxies come in gravity clusters, and these clusters are what are expanding apart rapidly.. the galaxies contained inside those cluster will all eventually converge over billions and billions of years...
also keep in mind that though space is expanding at ridiculous rates, the reason all the galaxies are held in place is because the extra gravitational presence of dark matter....with only the visible matter of the uninverse taken into account, and the rate of expansion, there is no way the masses of these galaxies should not be flying apart at ridiculous rates...less than half of one percent of the universe is what we can see....the rest is a complete mystery.
@63Bueno Forgot inflation. That other unknown and unexplainable phenomenon! But shouldn't we be at the opposite end of the universe to Andromeda and any other similar age galaxy due to expansion, or at least be unable to collide with them? For ideas about the expanding universe to be correct we must have started closer together than now and been continually pushed apart by expanding space for the last 12 BILLION YEARS....surely!!!!!! :( Head hurts! ;)
@63Bueno ...sorry, I take that back, and will take the duh as I am now reading incorrectly- none of the methods, including redshift, have anything to do with light travelling at a constant speed!
we are basically as old as the universe, that means that most every galaxy we see came after us...again, very easy to determine the age of these galaxies once u find distance based using light's constant speed....the Red Shift is used to determine how fast away the most distant galaxies are expanding away from us....light gets compressed as it moves through space, a red shift equals galaxies moving away(which distant ones all are).... Andromeda is blue(moving towards us)
Space seems to be uniform in every direction. If the universe is 13.7bn yrs old, and the Milky Way is 12bn yrs old that makes it one of the oldest objects in the universe, so shouldn't it actually be 'close' to the edge of the universe and shouldn't there be a distinction between the density and regularity of galaxies in one direction, because in one direction there is only the possibility for 1.7 billion years worth of activity, whereas in the opposite direction there is 12 billion years worth?
Is that even scientific- oh wait, hang on...my theory no longer works according to observation so I will arbitrarily invent something completely intangible and undetectable, but pretend it isn't by still basing it on the fundamental principles of my now proven to be incorrect theory, just so I can continue to be correct...hmm, what shall I call it...god...no, 'dark matter', that sounds better, more catchy!!
If u suddenly double the mass of the galaxy then wouldn't that then change the physics, orbits and calculations for the planets as they are moving inside the now heavier galaxy? Isn't that the idea of relativity? If it makes no difference its not particular relative, so relativity kind of fails one way or the other and the only reason Dark Matter has been inferred/invented is to make relativity hold true in the face of contradictory observations.
If the orbits of the planets make sense and obey the calculations for gravitation, mass etc, is it not far more likely there is another factor at play that we fully do not understand? That the current theories are incomplete, rather than just inventing invisible, unexplainable Dark Matter(?) that accounts for half the mass of the galaxy and explains the rapid movement of its stars and enables the theories and calculations to continue to work?
The need for religion shrinks exponentially to the degree at which science discovers and explains more and more aspects of our universe. The ignorance will, one day, give way to universal knowledge. When that happens, Justin Bieber will be gone as well ;) I have faith.
I'm sorry, but no one has discovered Dark Matter, or Dark Energy either, they are simply hypotheses and substitutions of knowledge for, the lack of mass and repulsive forces respectively. They have in no way been proven to exist. They don't even qualify as theories.
Documentaries like this need to mention this, and not sidestep it. Otherwise you might as easily conclude and say Dark Matter is God. Prove me wrong?
@agonyflips lol, agree. Just posted my own comment along similar lines then saw yours. Shows like this really annoy me because they always put the message across discretely that we, or our collective knowledge and theories, cannot be incorrect. And every time observation suggests they are, we'll invent something to plug the holes.
Well, you can most easily answer that question by understanding why the field was called Quantum Mechanics, & not Quantum Physics.
In laymen terms, Mechanics is the description of the observed, while physics is the theory explaining the observed. Though often used interchangeably, the 2 terms Quantum Mechanics & Quantum Physics are NOT the same. Description of something is not the same as explanation.
How did I know that when I scrolled down to see the comments here, I knew the first thing I'd see is some arguement about god and christianity. If you deluded christians don't like this video, fuck off. Your grasp on reality is very questionable as it is, and you cheapen the very majesty of our understanding of the universe with your selfish, arrogant, and narcissistic view that it was all made just for humanity. When your stupidity dies out, the planet will be a better place.
@blindedby2monkeys yes god exists doesnt he. What about the attrocities happening everyday around the world, what about children that die everyday through famine or murder, what about the appauling holocaust of auschwitz? In there even religous people said god didnt go there, he stayed away. Fuck you and fuck your thoughts of an omnipresent fantasy called god. There is no fucking god, and you come here on this lovely video and try to shit on it. Go fuck yourself.
what really is remarkable is the fact that this whole documentary only talked about a mere tiny fraction of the milky way galaxy and its even more astonishing that there are billions of galaxies out there, that might be even larger and denser with stars then our own. im am convinced that mankind's future lies in space.
Amazing documentary. All this makes me wanna live billions years, just to see all those events happen. Discovering new life, first time human colonise new planet, etc. Will human last for millions years ? Billions years ? Will human spread into space, even see our own sun dissapear ? How far will we go into nature comprehending ? That's really fascinating ! That's unfortunate that we happen to live for such a short period of time.

The very nature of science is about learning and acquiring knowledge. Sometimes this means evaluating older data compared to newer, and revising our thinking. Some people want all the answers right away and unchanging. Religion provides that for the most part, in a tidy package.
Science is rougher and takes more than faith. You must be prepared to peer into the darkness and have the courage to say "I don't know... yet."

@jojo123469 Old hypotheses die off if new evidence emerges to refute or refine them. A theory in the scientific sense is a body of demonstrable, testable facts. You use theory here to mean something which has no evidence and is essentially a priori assumption such as thinking a god exists with no discernible evidence. Where scientific theories are a posteriori justifications based on experience.

Science is the new secular authority. Scientists the new rational diviners of our reality and existence, our truth, like priests were the old spiritual diviners of our truth. When either make statements that don't match our experience of reality we shouldn't just bow our heads and baaah at them in acquiescence and obedience- we should question them, and if they don't have the answers they shouldn't have our obedience. They are not an undeniable authority. They are not a church.

What I wanted to illustrate to someone, who hasn't been commenting on this video, is a few fundamental truths about human nature.

@63Bueno Human truth is far easier to understand than the universe, easier to study.

I suggest u look into quantum physics if want to see just how strange the human mind can actually be..it turns out, the mere act of whether or not a human mind observing a particle, deteremines whether that particle acts as a particle or a wave...quantum entanglement(when 2 particles entangle) shows that one particle affects the other INSTANTANEOUSLY correlationally no matter the distance.this is probably the explanation for twins being able to sense other's pain immediately..

@63Bueno I don't require QP to know how strange the mind is, it is obvious from the experience of life. As complicated as it is, it still adheres to certain truths- I have just been able to predict your behaviour and responses (or a similar persons) based on no empirical evidence, theories or equations- I just used my own mind and knowledge of how it works, my experience and an innate sense and knowledge I have gained from living my own life, being thoughtful and observant.

@63Bueno I started off with the premise that no matter what argument, or how valid, was put across a certain type of person would never concede that there is a possibility of what they presume to know being incorrect once they have let their mind settle on certain 'truths' about their existence, our knowledge of it and what respected (chosen) authority authenticates it for them- they become rigid, mentally. We are all guilty of that mentality to varying degrees. Just look at religion.

Howabout the Big Bang- in a universe governed by causality in every single way, which is what makes all the Darks a necessity for our understanding- the universe spontaneously created out of an infinitely small and dense...'thing', that we call a singularity, for absolutely no reason whatsoever. Everything from nothing for no reason at all. The diametric opposite of causality. Dark your way out of that puzzle?
TheSoulDoubt 2 weeks ago
Dark means 'don't really know whats going on'. But as Dark is currently propping up, as in stopping them from collapsing (so Dark is more of a simulated scaffold structure to hold our ego and pride up as much as the universe), so much previous scientific work and theories scientists find it conflicts with their sense of pride to say 'don't really know whats going on'. So they adopt a more fancy name that gives the impression that they do know whats going on so they can still sound scientific.

Space expands faster over time- in 5bn years the universe should be more than a third as large again- so are they speeding up/slowing down and how come, if we are so certain of things like expansion rate, orbits, gravity, distance, speed, etc, there is a margin of error of 2bn years on an object we can see clearly, determine the distance of so accurately, its speed and trajectory and have such a good understanding of how fast space is expanding!?

The start of this chat was asking how astronomers can be sure of cosmic distances, not what the correlation between lights age, speed and distance covered was. And the reason for that was because Andromeda colliding with the Milky Way in 3-5bn years seems strange. Space is expanding rapidly and can exceed light-speed. The universe has, apparently, grown to be at least 14500mpc across in just 13.7bn years, and as objects grow more distant the effect of gravity weakens...

There can be no edge of the universe if space is uniform in all directions, so its size and age cannot be determined. If it isn't uniform in all directions, theres an edge, then our galaxy at 12bn years old should be closer to an 'edge' than a 'centre', so when we look into space we should notice a distinct lower density of objects in the 'edge' direction to the 'centre' direction. If direction is irrelevant, then our estimations at the dimensional extents of the universe are invalid...surely!?!

@TheSoulDoubt You've made an error--you said "space is uniform in all directions", but how do you know this? The only 2 ways you could know this is if you either traveled to the edge of our universe and actually saw what happens to space at the edge, or studied the calculations of the cosmological beginnings of our universe as it expanded which invites the question: what was it expanding in? Truth is neither you nor I knows if space is uniform at the edge.
PenthouseDiaries 2 weeks ago
@PenthouseDiaries I quoted from many different astronomers from several sources that space appears to be uniform in all directions which they base on the Hubble ultra-deep field observations- so no, I don't know this at all and as u state neither really does anyone else which is why I question some of the presumptions made about our universe. Conceptually, what is an edge? If it is an edge in 4-dimensions the word doesn't really mean anything to us because it is beyond our ability to perceive.

@TheSoulDoubt Black holes have an edge in 4-dimensions.

@PenthouseDiaries Aren't blackholes dimension-less? They are the opposite of dimensional existence. Imagine what happens to light when it is emitted from an object inside the event-horizon in an outward direction. Does that light travel any distance before it is bent back on itself down the singularity, or is it instantaneous- does that outward direction still exist? Nothing can travel in that direction anymore, so travelling in those conditions is instantaneous, u can never backtrack at all
TheSoulDoubt 2 weeks ago
@PenthouseDiaries So where u started is always exactly where u are and u are immediately at the end of your journey without actually moving anywhere- the idea behind wormholes. Blackholes are the end of our dimensional existence as far as we can tell. Thats why we don't really understand them or the (supposed) origins of the universe. Singularities don't obey our laws. Gravity, time and space all go to SHIT in them!

@PenthouseDiaries If anything they appear 1-dimensional...or even 0-dimensional. there is only one way to go once u cross the event-horizon- into the singularity, instantly.
TheSoulDoubt 2 weeks ago
@PenthouseDiaries If not then for it to be an edge in 3-dimensions obviously it cannot be uniform otherwise it wouldn't be an edge. Like the edge of a cliff is not uniform- one way is a 300ft drop the other way is level land, if this isn't the case it isn't an edge. I'm sure I read somewhere that the best hypothesis for the universes shape at the moment is toroidal, which involves extra dimensions which then renders most of what we can think about the universal size, shape and its edge obsolete.
TheSoulDoubt 2 weeks ago
So how do we come up with the dimensions of the universe or its age? We look at red-shift in light from distant, ancient objects. How fast they are moving away from us...but our galaxy is an ancient object (and space is uniform in all directions), so if we travel to an object at the edge of the visible universe 60bn light years away and continued to look in the same direction as we had travelled, would we see the same uniform density of objects and another one 60bn light years away?
TheSoulDoubt 3 weeks ago
If this isn't the case, the expansion of space makes the idea of something being somehow central irrelevant, how can the size of the universe, or its age, or even the Big Bang be accurate? If there is no such things as a central starting point, no difference in any direction, how can things like time and distance be established? If u can't ascertain where something started from, u can't ascertain how long its taken to get where it is or how far its gone-

sure u can...u just rewind the clock using the laws of physics...u can measure light by its speed(186.000 miles per second), so u can use that to then determine how long it has taken to reach us, thus its age...
63Bueno 2 weeks ago
@63Bueno I'm sure there are very good methods for establishing these things for people to be so certain about them, but u can't do it just from knowing lights speed, u need more information than that. A car has just pulled up outside your house and it has been travelling at a constant velocity of 100kph- tell me how far it has travelled or where it started from or how long it took to get there with just that information alone? How do u determine lights age if u don't know when it was emitted?
TheSoulDoubt 2 weeks ago
@TheSoulDoubt Light from distant objects reaching us now was emitted, in some cases, before our planet even existed- so knowing its speed does not tell u how far it has travelled and its age. Doppler effect (as far as I understand it) determines that an object is moving away or towards u, red or blue-shift, but again not how long it has travelled (hence distance travelled also) unless u already know its time of origin.

@TheSoulDoubt
Light always travels the same speed...Scientists are able to determine a stars distance by all sorts of various methods depending upon how far it is...They use the term "light year"(how far light travels in a year which is 6 trillion miles) to describe how far away these stars are since the speed of light is constant....Our nearest star is 4 light years away(24 trillions miles)....the observable universe(just what we can see with our modern telescopes) is 13 BILLION LIGHT YEARS

@63Bueno How much further than Hubble do you think the James Webb telescope will be able to see? I think it's suppose to sit 1 million miles from Earth? (I think, if I remember correctly.) How far away is Hubble?
MadeInOregon27 2 weeks ago
@MadeInOregon27
we will NEVER be able to see beyond what we see today with telescopes....all galaxies outside 13 billion light years away are rushing away from us(and everything) FASTER than the speed of light, which means their light will never reach us...

@63Bueno Are we moving/traveling like that also?
MadeInOregon27 2 weeks ago
@MadeInOregon27
yes....if we were to be in one of those galaxies on the edge of our visible universe. then our Milky Way would be on the brink of saying its final goodbye as its expansion away would outrace its photons(what light is made of)
63Bueno 2 weeks ago
@63Bueno Yes, I understand that light-speed in a vacuum is a constant- celeritas, as its referred to often, however that does not, as far as I can see, inform u how far away something is. Photons are arriving here constantly from these objects whether 4 ly away or 13bn, how do scientists tell when the photons left the object and hence how far away they are?
TheSoulDoubt 2 weeks ago
@63Bueno Light speed was determined by timing how long it takes light to reach a destination from the time it is emiited- like turning a torch on and then seeing how long its light takes to reach somewhere. Stars and galaxies have been emitting light constantly since before we were able to time how fast its travelling, so when we observe an object that is so distant how do we know when the photons arriving here now left the object and how long they have been travelling for?
TheSoulDoubt 2 weeks ago
@TheSoulDoubt
by determining how far away the object omitting light is..duh! u just said it yourself. light moves at a constant speed, so its distance is directly correlated to its age..
63Bueno 2 weeks ago
@63Bueno omg how many times do I have to say the same thing- knowing lights speed does NOT tell u when it started travelling and therefore does NOT tell u how old it is and hence does NOT tell u how far it has travelled. What are these other methods is what I have been asking, do u know? Keep the duh for yourself until u can actually correctly read and interpret what is written please :)
TheSoulDoubt 2 weeks ago
@TheSoulDoubt
they dont use the photons to determine distance, they use other methods,and then use lights constant speed correspondingly, u seem to have it backwards..
63Bueno 2 weeks ago
@63Bueno Is it interstellar triangulation? Although I am finding it hard to see how that would work as all bodies in space are in motion, so technically there are no fixed points of reference with constant angles to be determined.
TheSoulDoubt 2 weeks ago
@63Bueno Don't worry about, it found my answer. Radar in the solar system. Parallax for nearby stars. Cepheids in our galaxy. Supernovae for other galaxies. Redshift for very distant objects.
...and, surprise surprise, none (except redshift which is still only based on Hubbles theory and not, at this time, factual) of the methods used have anything to do with light travelling at a constant speed of 186,000mph!
TheSoulDoubt 2 weeks ago
@TheSoulDoubt
i never said the methods had anythingto do with light speed..all i stated is that they found the distance using various methods(u just stated those various methods) and then used light's constant speed to get its age....we know our galaxy is one of the very early galaxies, so I would assume that since we are basically as old as the universe, light speed would correlate very well to determining lights age in the universe for us...
63Bueno 2 weeks ago

and light doesn;t travel at 186.000 mph.....good lord....its 186.000 miles per SECOND....671 million miles per hour...

@63Bueno lol...typo! ;) Yes, and Andromeda is about the same age as the Milky Way, so we've been in proximity since nearly the beginning in, what was, a far smaller space, so we should have been closer together, caught in same orbit, whatever. So if we haven't collided already in all that time- how come we will in 3-5 billion years when we will be so much further away from each other than we were at the start?
TheSoulDoubt 2 weeks ago
@TheSoulDoubt
we are CLOSER to Andromeda now then when we both first formed 12 billion years ago if u relate it to the expansion of the universe as well....not sure how far apart we started but undersand we are only 2.5 million light years from Andromeda and it will be another 3 BILLION years before we collide....the speed with which the two galazies are moving towars each other is not very fast...

@63Bueno Just been looking at info about speeds, clusters, superclusters, Hubbles Constant, planes, The Great Attractor and more and it all lead me to Dark Flow. Everything moving towards a sibling universe (?) or an area of spacetime fundamentally different to our own (???) outside observable limits...which is where I get off!
TheSoulDoubt 2 weeks ago
@63Bueno So if u add all the Darks together, Energy, Matter and Flow u get EMF- which stands for Electro-Magnetic Fuck-up...which is appropriate because we can't see or detect any of it!! ;)

@TheSoulDoubt
whos claiming to know what is goin on in the grander scheme of things? thats exactly why they refer to it as dark energy and dark matter, they havent a clue, thats what the dark mean as u stated....obviously we only understand an incredibly small fraction of this life.. but just think of the exponential rate of technology and discovery, its possible in our lifetimes we will know much more, but there of course will always be more, its a never ending process...
63Bueno 2 weeks ago
@TheSoulDoubt
but u are wrong on one thing....we CAN detect dark energy and dark matter, by their gravitational presence...obviously we cant see it yet, it doesn't interact with light like regular matter does
63Bueno 2 weeks ago
@63Bueno No, that is an assumption based on general relativity being the complete picture of gravity. We infer there existence by first assuming relativity is entirely correct then making-up other invisible 'matter' to compensate for a lack of apparent mass in the universe according to relativistic effects. Hey, u know what, I don't interact with god the way the pope does so is that why I can't see Him?
TheSoulDoubt 2 weeks ago
@TheSoulDoubt
they ARE able to observe dark matter's gravitational bend on light....so they have more than just general relativity to back up its existence...
63Bueno 2 weeks ago
@63Bueno How so when general relativity gives us our best understanding of how gravitation works by curvature of spacetime, so anything exhibiting gravitational effects is dealt with through that theory- it only bends light because (if?) it is some form of invisible matter curving spacetime in accordance with relativity, obeying its laws. Without general relativity it wouldn't even (be presumed to) exist!
TheSoulDoubt 2 weeks ago
@63Bueno U said it yourself, without DM there wouldn't be enough mass to hold galaxies together, they would fly apart- thats what relativity tells us should happen with the amount of observable matter and mass. Without DM curving spacetime, keeping cluster structures together and bending light in its spare time, everything would fly apart, relativity and expansion say so...so how do they have more than general relativity to back it up?
TheSoulDoubt 2 weeks ago
@TheSoulDoubt
u said there is no way we can see the dark matter, that its just based on purely relativity being correct...then why can we SEE bent light where there is no observable mass to bend it?? because mass of another kind is bending it, the dark matter...
they have supercomputers that construct galaxies based on relativity. these galaxies just dont form with normal relativity as one would suspect but when right amount of dark matter is added they look EXACTY like a spiral galaxy
63Bueno 2 weeks ago
@Bueno63 Good morning. Gravitational lensing has been seen round clusters where there is not enough 'supposed' mass to bend light in such a way, which is based on relativistic calculations- the same ones put into those supercomputers so they would give the right formations. It only happens where there is visible mass, just not enough to have the effect relativity states should be present, so therefore we infer it must be Dark. Inferring is not evidence.
TheSoulDoubt 2 weeks ago
@63Bueno We have been running extremely sophisticated simulations on supercomputers for many different things for years, like the weather- but we find computers can only simulate information we are able to provide them with because last time I looked computers weren't actually creating reality off their own backs- that was just a film called the Matrix I'm pretty sure.
TheSoulDoubt 2 weeks ago
@63Bueno Weather is only relative to this planet and we have far better access to all the necessary information and variables that contribute towards weather and really should understand the systems involved much better as we have far more experience of them, they are right here with us every single day and have been for 10,000 years, we can see them and touch them and interact with them and yet they still can't quite get predictions or simulations of weather right can they!
TheSoulDoubt 2 weeks ago
@63Bueno And I'm guessing that our weather here on this tiny little planet is not as complicated as the formation, structure and movement of the entire cosmos. It may well be real, but in 80 years no-one has found any physical evidence for it and THAT IS a problem. If we add Dark Matter to weather simulations maybe they'll be more accurate too....who knows?
TheSoulDoubt 2 weeks ago
@63Bueno What else can we add to our 'knowledge' of the universe that we only need an idea to support and then infer from- I noticed this morning that when I prayed the sun came out, does that mean weather is influenced by prayer? Anyway its obvious that my questions about your belief in Dark Matter disturb u somewhat and I didn't come here to disparage your faith or need and desire to believe. Just came for a look.
TheSoulDoubt 2 weeks ago
@63Bueno One last thing, Dark Matter has mass if its real or it serves no purpose and doesn't need to exist- it is presumed to have neutral charge and so doesn't interact with ordinary matter except via gravity, and it was separated from baryonic mass around the formation of the CMB so does not interact with radiation either, but its been around just as long and has mass and gravity- so why hasn't it formed into Dark Massive stars or blackholes when ordinary, lighter matter, has done so?
TheSoulDoubt 2 weeks ago
@63Bueno Why has it just remained as this bizarrely shaped floating structure threading through the universe- why, if it has so much mass and gravity and is unaffected by all the things ordinary matter is effected by, hasn't it/doesn't it coalesce into its own spherical structures like stars and planets? Why doesn't it collect into stars cores and collapse them by pushing their mass beyond a stable amount?
TheSoulDoubt 2 weeks ago
@63Bueno It can pass through anything, interacts with nothing- why is it just floating around in nondescript 'webs' that have no gravitational structure themselves and yet supposedly gives the entire universe ITS gravitational structure?
TheSoulDoubt 2 weeks ago
@63Bueno Theories based on other theories to keep previous theories working. Big Bang needs DM to work. Relativity needs DM to work. It could be real, I don't deny that- its just that I also don't deny that we could be WRONG, and as soon as we let arrogance and pride inflate our little minds to unrealistic proportions like the church did in Galileos time, we find it hard to accept that maybe we have got a few things WRONG, and thats what hinders progress most.
TheSoulDoubt 2 weeks ago
@63Bueno And we kid ourselves that we really know and understand whats going on in the greater scheme of things? That we are just a Higgs-Boson away from having a complete picture of everything? Seems like a bit of an unrealistic presumption when we don't actually know what 99% of existence actually is...well its Dark, we know that much...which is also appropriate because thats where we are- in the Dark.
TheSoulDoubt 2 weeks ago
@63Bueno Personally I think we still don't understand what 'gravity' really is...sorry Albert! Which is why we still have so much Dark obscuring our vision. They are all related to what we call 'gravity'...kinda makes more sense to say something is wrong with our theories about gravity and change them rather than completely changing perceptible reality across tens of thousands of megaparsecs and beyond so we don't have to alter the theories.
TheSoulDoubt 2 weeks ago
@TheSoulDoubt
id say the theories are quite sound for the HUMAN observable universe at this point....it doesn't make sense to throw away all of our theories and search for the truth using dark matter and dark energy(the vast majority of the universe)...we know nothing about them, all we can do is measure their presence...i mean, we cant abandon everything we know because we just found out theres a whole lot more to the picture than frst imagined...u build off prior knowledge and move forward
63Bueno 2 weeks ago
@63Bueno And no doubt we will actually do that in a few years time when we take our heads out of our asses. At the moment we are not building on previous knowledge, we are randomly inventing our own reality to suit our needs and have rejected the empirical process to make our previous knowledge still apply as we encounter more and more contradictory observations to our theories predictions. That is not progress- its bordering on delusional.
TheSoulDoubt 2 weeks ago
@63Bueno Not saying we should throw anything or everything away, just reassess some very specific things as they just don't seem to work unless we add in our own magic fairy dust that really doesn't exist as far we can tell, it is simply suggested that it must be there if our theories are accurate...which they aren't according to known, observable reality, which is why we have the magic invisible ingredients. Thats borderline faith, not science.
TheSoulDoubt 2 weeks ago
@63Bueno We somehow arrived at the state of mind that we have discovered so much that we must just about know it all. More young people would probably get into science and astronomy and stop watching x-factor if they didn't keep getting told by all these shows that there isn't really anything left to discover, that we have figured it all out, that theres not much left to know.
TheSoulDoubt 2 weeks ago
@63Bueno We've come a long way, sure, but one thing we should have learned by now is that reality operates in unimaginable scales and we are probably at the tip of the iceberg with all the really big stuff hidden beneath the surface that we are barely scratching.
TheSoulDoubt 2 weeks ago
@63Bueno How can it possibly STILL be moving towards us when it has had 12bn years to reach us, needs another 3-5bn years to get here, and started heading our way in a relatively tiny universe where gravitation should have been far stronger? It doesn't make sense. And as revenge for pointing out my horrific lightspeed typo, light gets compressed or stretched into higher/lower wavelengths depending on whether an object is moving towards or away from us ;)
TheSoulDoubt 2 weeks ago
@63Bueno Its 1pc away now, so where was it 12 bn years ago when the universe was tiny compared to what it is now? If it takes another 3-5bn years to reach us that is a greater overall time than the (presumed) age of the universe! How is that possible when the space between us would have had the time to expand to the size of the entire universe as it is today which is around 14500mpc in any direction?
TheSoulDoubt 2 weeks ago
@63Bueno ...aaaand the expansion of space is supposedly speeding up aaaand can exceed lightspeed- how does anything collide over such huge timescales and distances in those conditions when the moving material objects cannot exceed lightspeed and they originated closer together at around the same time?!!
TheSoulDoubt 2 weeks ago
@TheSoulDoubt
galaxies can collide over such vast distances because they are still bounded together by gravity....most galaxies come in gravity clusters, and these clusters are what are expanding apart rapidly.. the galaxies contained inside those cluster will all eventually converge over billions and billions of years...
63Bueno 2 weeks ago
@TheSoulDoubt
also keep in mind that though space is expanding at ridiculous rates, the reason all the galaxies are held in place is because the extra gravitational presence of dark matter....with only the visible matter of the uninverse taken into account, and the rate of expansion, there is no way the masses of these galaxies should not be flying apart at ridiculous rates...less than half of one percent of the universe is what we can see....the rest is a complete mystery.
63Bueno 2 weeks ago
@63Bueno Forgot inflation. That other unknown and unexplainable phenomenon! But shouldn't we be at the opposite end of the universe to Andromeda and any other similar age galaxy due to expansion, or at least be unable to collide with them? For ideas about the expanding universe to be correct we must have started closer together than now and been continually pushed apart by expanding space for the last 12 BILLION YEARS....surely!!!!!! :( Head hurts! ;)

TheSoulDoubt 2 weeks ago
@TheSoulDoubt
we are basically as old as the universe, that means that most every galaxy we see came after us...again, very easy to determine the age of these galaxies once u find distance based using light's constant speed....the Red Shift is used to determine how fast away the most distant galaxies are expanding away from us....light gets compressed as it moves through space, a red shift equals galaxies moving away(which distant ones all are).... Andromeda is blue(moving towards us)

Space seems to be uniform in every direction. If the universe is 13.7bn yrs old, and the Milky Way is 12bn yrs old that makes it one of the oldest objects in the universe, so shouldn't it actually be 'close' to the edge of the universe and shouldn't there be a distinction between the density and regularity of galaxies in one direction, because in one direction there is only the possibility for 1.7 billion years worth of activity, whereas in the opposite direction there is 12 billion years worth?

Is that even scientific- oh wait, hang on...my theory no longer works according to observation so I will arbitrarily invent something completely intangible and undetectable, but pretend it isn't by still basing it on the fundamental principles of my now proven to be incorrect theory, just so I can continue to be correct...hmm, what shall I call it...god...no, 'dark matter', that sounds better, more catchy!!
TheSoulDoubt 3 weeks ago
If u suddenly double the mass of the galaxy then wouldn't that then change the physics, orbits and calculations for the planets as they are moving inside the now heavier galaxy? Isn't that the idea of relativity? If it makes no difference its not particular relative, so relativity kind of fails one way or the other and the only reason Dark Matter has been inferred/invented is to make relativity hold true in the face of contradictory observations.
TheSoulDoubt 3 weeks ago
If the orbits of the planets make sense and obey the calculations for gravitation, mass etc, is it not far more likely there is another factor at play that we fully do not understand? That the current theories are incomplete, rather than just inventing invisible, unexplainable Dark Matter(?) that accounts for half the mass of the galaxy and explains the rapid movement of its stars and enables the theories and calculations to continue to work?

I'm sorry, but no one has discovered Dark Matter, or Dark Energy either, they are simply hypotheses and substitutions of knowledge for, the lack of mass and repulsive forces respectively. They have in no way been proven to exist. They don't even qualify as theories.
Documentaries like this need to mention this, and not sidestep it. Otherwise you might as easily conclude and say Dark Matter is God. Prove me wrong?

@PenthouseDiaries,
"Has it been proven dark matter does NOT exist?"
Well, you can most easily answer that question by understanding why the field was called Quantum Mechanics, & not Quantum Physics.
In laymen terms, Mechanics is the description of the observed, while physics is the theory explaining the observed. Though often used interchangeably, the 2 terms Quantum Mechanics & Quantum Physics are NOT the same. Description of something is not the same as explanation.
