I understand how we know the speed of galaxies. Red shift. But the light we are measuring left the galaxy say 2 billion years ago. So we can tell it's speed 2 billion years ago. How do we know what it's speed is now? Thank you.
Oh, sorry. We know the speed of the galaxies not now, but back then. But even if the light waves are really old, you can still measure how fast they WERE accelerating away. Does that answer your question?
@dudejohnny Thank you for your reply, but no, I am not sure I understand how to measure acceleration. I understand the measurement of speed by red-shift, but not acceleration. Acceleration is the rate of change, or first derivative, of speed. That would imply to me that we have observed an object for a long enough period of time and calculated the rate of change of that speed. Is that how is it done? Again, thank you for the dialogue.
I think my previous comment was slightly wrong and might give you the wrong idea, so I'll explain it better. What they do is measure the wavelengths of different galaxies and the trend they found was, the farther away the galaxy was, the more intense the red shifting. This was true for all the observations on average and you would only see something like that if space were actually expanding. If it wasn't, you'd probably see primarily blue shift. Then add some tricky math and bam.
if "where" describes three sets of coordinates and "when" describes a 4th, what words can be used to describe the 5th and 6th dimensional points? i hear lots of talk about multiverses and stuff like that, so would those other two coordinates have to do with the where/how position of a point across every possible alternate reality? or something?
FFFFFFFFFFFFFFFFFFFFFFFFFFUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU I just clever enough to know that I'm dumb enough to never understand this... :(
measuring magnetics seems to need 6 facets; east intensity, north intensity, positive down, positive east etc....everything is so swirly... Happy Oestre xx
Just a random question: what state of matter is HCl (Hydrochloric acid). I'm not talking about dissolved/mixed HCl in water. I want to know whether pure HCl is a gas, liquid or a solid. Is it like a oxygen (gas) dissolved in water, is it a liquid mixture or is it like salt dissolved in water? An answer would be appreciated.
@xDestroyer2x HCl is not an acid - it's a gas under normal conditions. It is called an acid when dissolved in water. When they write HCI(acid) it means HCl*nH2O.
@Tmaker197812 I'd say that's equally misleading, as HCl(acid) doesn't require (aqua). For example, you can use it within methanol to protonate an acid-catalyst in an anhydrous environment.

@akashashen Don't be an ignorant asshole. He said string theory, not M theory, and indeed all five variations of the string theory postulate ten dimensions, not 11.
@paulcmnt I think most of the geek-humor theorists followed the joke, but you, Sir, are an ignorant asshole. Allow me to clarify string history for you, in chronological order, they are: Supergravity, 6 or 7; Bosonic, 26 dimensions; Super, 10; M, 10 or 11;
This skims orders and model extrapolations (type I and II, hetero-homo-genous, holographic principle, modern brane theory), but one could note that M follows as an extrapolation of Super, but, hey, I'm just an asshole.

Einstein equations are significant when they make predictions. The deflection of light by the Sun and Mercury's orbit were the first major predictions. Einstein's equations never made any predictions related to an accelerated expansion or dark matter or dark flow. Theoretical physics is about making prediction. Experimental branches of science are based on observations. My point was, you cannot as an Astronomer simply assign what is a mystery to a theory that never made such a prediction.
How can you honestly say that constant has anything to do with the acceleration of the universe. The Cosmological constant is a fudge fact. You change its value based on the experimental result. When yo do this in theoretical physics, it simply means you do not know what you are talking about. It's like a mathematician change statements in a proof with no reason just to get the right conclusion.
@BinaryStars100 You're completely wrong. Einsteins equations are very valuable. The fact that the cosmological constant could have any value from a theoretical point of view doesn't mean that these equations are meaningless. There's still lots of predictions that Einsteins equations make, even without knowing the value of the cosmological constant. Well, if you then find in nature that the equations are right, you can actually measure the cosmological constant. That's just awesome.
You're completely wrong (#2). The cosmological constant is not a "fudge factor"; it is analogous to the constant of integration in calculus. What it basically means is that you have the *shape* of a curve correct, but not its height above the x axis. The actual height is fixed by experiment.
@pseudorandomly The foundations of a theory are very important. Einstein said, "Matter curves space" but he also says space is nature curved. So, it is perfectly acceptable to have curved space without any matter or Non-Euclidean. General Relativity is a mathematical theory about gravity. The real world is mechanical with a mathematical description. The real world is telling us we got it wrong.
"The real world is mechanical with a mathematical description." True, but that is a complete non sequitur to your earlier statement that the CC is a "fudge factor". It's not; it's a completely natural consequence of Einstein's equations.
"The real world is telling us we got it wrong." True again, in that we long assumed the cosmological constant was zero. Now, the observations of an accelerating universal expansion points to a non-zero CC as a particularly good explanation.
@pseudorandomly The Cosmological Constant is not a natural product of Einstein's logic. He put it there because he like most at the time thought the universe was static. Then he took it out after Hubble showed it wasn't. It was put back when it was discovered the universe was accelerating. When they discover what Dark Energy really is they'll take it out again because it has nothing to do with CC. CC is actually a free parameter, adjusted to fit the data. Quantum mechanics full of them.
"The Cosmological Constant is not a natural product of Einstein's logic." Well, you're simply wrong about that. It is an arbitrary constant akin to the constant of integration in integral calculus; it is a natural part of the equations. Einstein set it non-zero to force a static universe; when Hubble showed the Universe was expanding, he and everybody else began regarding the CC as zero. In point of fact, the CC is very much in the running as the origin of dark energy.
@pseudorandomly Feyman, "I'm sorry I'd rather not understand things than be certain of something which is wrong". In the running is not how CC is packaged with respect to Dark Energy. I have seen a number of programs where CC is the conclusion or certainty. Arbitrary constants in integral calculus are initial conditions when applied to physical problems. If a theoretical physicist sets these initial conditions to match experiment it is a fudge factor, if he predicts the condition its logical.
"I have seen a number of programs where CC is the conclusion ..." Well, yes. It so happens that the CC is a quite good explanation of the universal acceleration. So, within the observational errors, CC fits -- what else are they going to say? There are other possible explanations, some of which have already been ruled out to a greater or lesser extent; some new explanation(s) may crop up before the situation is resolved. It's the nature of exploring the unknown.
has anyone considerd? That the cosmological constant maybe effected by the inner space< (space between the electon and proton) as it relates to the gravitaional forces when viewed from a quantum perspective. That is a lot of empty space between, not only the electron and the proton! But also between the individual atoms themselfs. The universe is expanding because, Gravity! Is spaced consistantly and evenly, making it have a weaker attractive force as distance Increases, increasingly.
"Coming from the world of particle physics, what can you do with a cadbury's creme egg?" .... my first thought would be ram a couple into each other at 99% light-speed and see what comes out ;-) I guess that's why I'm not a physicist :-(
@BulletMagnet83 For a split second you would have hundreds of smarties and m&ms that weigh slightly more than the two eggs combined. They believe that the elusive Higgs peanut may be detected in the Large Cadbury Collander.
I am just 11 but i study physics (Quantum and Astro-physics) i find it really intresting. first i wasnt able to solve physics equaution , but when i saw you channel i am getting better and better that i am now teach grade:10 physics! So i really want to thank you for your absouloutley great effort! And one day i wanna become a student a Nottingham :)!
@DutchKid121 Since you're already in university it may be a little hard to have the time to. It's just cause I really regret not to have taken university courses on the internet before. Now it's a bit late since I'll soon go to university myself but oh well.
@kristijan0kroflin humans live in 3dimensional space in a 4dimensional space time. dimensional analysis is completely seperate from this topic, thats about concluding what power a particular "thing" has (such as lenght, mass, time etc). Also Gravity and weight are also diffrent, w=mg (weight = mass x Gravity) it is possible to have a 0gravity experiment and be no weight (m (5kg)x g(0) = w(0) , however you can still have G and have no W where there is a lack of M. e.g (m(0)xg(9.8) =w(0).
Y'know I get it qualitatively, but not at all quantitatively. I suck at math, but I understand the principle. It shows how much we don't know and what we may learn in the next few millenia. We may discover time travel, and completely obliterate ourselves in the process....some things are not meant to be done. That certainly doesn't mean it's not good food for thought. I liked it!
So does that mean the reason gravity is so much weaker than the other forces is because it is divided between more dimensions then the rest? CRAZYYYY!!! Has anyone discovered why it can penetrate the membranes unlike the rest? More videos on dimensions please!!
I can't believe I found this channel only a couple of days ago. Better late than never, I guess. Absolutely love it!!! Thank you for sharing with the world.
This is something I never understood: what does it MEAN that a dimension has a certain size? What does a "small dimension" even mean? Is it just that there a small set of values that that coordinate can take? E.g. if the X dimension were only 100 meters long... what would happen if I keep walking after I got to the corner of my street?
My brain is having trouble with the idea of gravity leaking into other dimensions as if it were a puddle of water. And yet the discriptions has me wondering if gravity is mostly in Rho and Theta but is polarized and what we get is just scatter.
I don't suppose that would make any sense with the math?
I remember back to my college days and struggling with Physics. More accurately the professor and his tendency to use math outside the requirements for the class to explain concepts. I barely graded out of the class with a C. Now I work with computers, and while I love it - I sometimes think back to those days and wish I had access to such a wonderful professor being able to explain things in pictures with the mathematical foundation as well. His students are very lucky. Thanks for the vid.
just found myself pulling my hair on my head in a circular motion.:) I think there should be one more video on the topic elaborating the rho and theta and the gravity acting on the curved surface.
i wish i had a camera-person and the ability to articulate my points so clearly, i've figured out a way to visually demonstrate up to 6 spatial dimensions without violating superposition in a pretty simple way
Well I wish you did too, cos although i'm not a student, I love these videos and would love to understand slightly what they are saying. At the moment string theory, more than four universes, the "God particle", quantum theory and so on just seem like stuff we should take for granted as being correct even tho they seem to be nothing more than illusions to me, ways of explaining what has not yet even been understood.
If electrons travel much easier through the atoms when the atoms are have a lower temperature and vibrate less, why does cars have a bigger problem receiving electricity in the winter when it's cold? (:
@Swiftynine Because the problem with electricity in cars in winter isn't the travel of electrons in the wires. The electric energy of the battery is stored as chemical energy and needs chemical reactions to be "set free". As chemical reactions as a rule of thumb are only half as fast when you decrease the temperature by 10 degrees, a cold battery can have a hard time providing enough energy at the time needed.
As a complete n00b I cannot get the idea of a dimension being 40 microns or what ever in size. How can a 5th and 6th dimension have properties of the other 4?
I´m thinking like "My height is 40mircons in my width" ?

It's only after I left school that I started to appreciate this stuff and I've learned a lot from this channel, it still amazes me that someone like myself with absolutely no previous education in the sciences can still at least grasp some of what's said in this video. Thank you and please never stop.

I am just 11 but i study physics (Quantum and Astro-physics) i find it really intresting. first i wasnt able to solve physics equaution , but when i saw you channel i am getting better and better that i am now teach grade:10 physics! So i really want to thank you for your absouloutley great effort! And one day i wanna become a student a Nottingham :)!

@DutchKid121 Since you're already in university it may be a little hard to have the time to. It's just cause I really regret not to have taken university courses on the internet before. Now it's a bit late since I'll soon go to university myself but oh well.

would dark matter be part of this "sixth dimension??"
ADizezedCrow 4 months ago
@ADizezedCrow i think it's possible becouse if gravity can "leak out" so it can "leak in" too.
i was wondering about the implication of that on neutrinos speed , can just neutrinos sometimes "jump" some space but actually move slower than c ?

@kristijan0kroflin humans live in 3dimensional space in a 4dimensional space time. dimensional analysis is completely seperate from this topic, thats about concluding what power a particular "thing" has (such as lenght, mass, time etc). Also Gravity and weight are also diffrent, w=mg (weight = mass x Gravity) it is possible to have a 0gravity experiment and be no weight (m (5kg)x g(0) = w(0) , however you can still have G and have no W where there is a lack of M. e.g (m(0)xg(9.8) =w(0).

Y'know I get it qualitatively, but not at all quantitatively. I suck at math, but I understand the principle. It shows how much we don't know and what we may learn in the next few millenia. We may discover time travel, and completely obliterate ourselves in the process....some things are not meant to be done. That certainly doesn't mean it's not good food for thought. I liked it!

So does that mean the reason gravity is so much weaker than the other forces is because it is divided between more dimensions then the rest? CRAZYYYY!!! Has anyone discovered why it can penetrate the membranes unlike the rest? More videos on dimensions please!!

lukas3606 8 months ago
This is something I never understood: what does it MEAN that a dimension has a certain size? What does a "small dimension" even mean? Is it just that there a small set of values that that coordinate can take? E.g. if the X dimension were only 100 meters long... what would happen if I keep walking after I got to the corner of my street?

Might be splitting hairs, but could the gravity leak be in the other direction and we only experience a fraction of it?
Digimaul 9 months ago
My brain is having trouble with the idea of gravity leaking into other dimensions as if it were a puddle of water. And yet the discriptions has me wondering if gravity is mostly in Rho and Theta but is polarized and what we get is just scatter.
I don't suppose that would make any sense with the math?
I think I might need a stiff drink.
meregrotta 9 months ago
I remember back to my college days and struggling with Physics. More accurately the professor and his tendency to use math outside the requirements for the class to explain concepts. I barely graded out of the class with a C. Now I work with computers, and while I love it - I sometimes think back to those days and wish I had access to such a wonderful professor being able to explain things in pictures with the mathematical foundation as well. His students are very lucky. Thanks for the vid.

Well I wish you did too, cos although i'm not a student, I love these videos and would love to understand slightly what they are saying. At the moment string theory, more than four universes, the "God particle", quantum theory and so on just seem like stuff we should take for granted as being correct even tho they seem to be nothing more than illusions to me, ways of explaining what has not yet even been understood.

I got a question for you!
If electrons travel much easier through the atoms when the atoms are have a lower temperature and vibrate less, why does cars have a bigger problem receiving electricity in the winter when it's cold? (:
Referring to the episode with the electro canon.
-Big Fan :D
Swiftynine 10 months ago
@Swiftynine Because the problem with electricity in cars in winter isn't the travel of electrons in the wires. The electric energy of the battery is stored as chemical energy and needs chemical reactions to be "set free". As chemical reactions as a rule of thumb are only half as fast when you decrease the temperature by 10 degrees, a cold battery can have a hard time providing enough energy at the time needed.

As a complete n00b I cannot get the idea of a dimension being 40 microns or what ever in size. How can a 5th and 6th dimension have properties of the other 4?
I´m thinking like "My height is 40mircons in my width" ?
btw: brain pretty much exploded, good job!

"we" and "didn't "know""...first of all "they" don't "know" - and second of all he shows that he's not secure of his assumption - and therefore has to say "we".

I watch these videos because I never did any science in school, it was elective and I chose Home Economics for the free food and I was the only guy in the class - I liked those numbers. It's only after I left school that I started to appreciate this stuff and I've learned a lot from this channel, it still amazes me that someone like myself with absolutely no previous education in the sciences can still at least grasp some of what's said in this video.
