Many Ast/Astro Phys believe in Intelligent design? Like what 16 or 17 out of thousands? Just more immatures who want to believe fairy tale beings keep us safe from oblivion at death... and about Anti/Matter annihilation expanding the universe; uhm so where is the Heat and Energy that would be caused? No such observations have been made; which would be so OBVIOUS!

[CACBCCCU]

There's an article titled "Antigravity Could Replace Dark Energy as Cause of Universe’s Expansion" with artwork titled "Illustration of Antimatter/Matter Annihilation. (NASA/CXC/M. Weiss)" looking a lot like the Bullet Cluster. I disagree with the article's CPT symmetry concept because time reversal's redundant with charge reversal and spin reversal, CP=T; and, if including gravity reversal, it's CPG=T. So, there's no "time charge" and CP violation somehow holds CPG symmetry, not CPT symmetry.

[CACBCCCU]

Relativity was tested on earth with interferometers 1/2 year apart, I guess to see if there's an aether drift for the sun and earth, and no drift for either one was seen. So I'll avoid etheric models, but I'd still apply an antimatter-antigravitational flow approach to this cluster as an orbiting set of galaxies, also I'd apply quantum gravity rules incorporating a galaxy-scaled balanced wave property and a form of graviton scattering-based effect involving self-centering corner-reflection.

[CACBCCCU]

Something seems to be up with the reply settings on this video, now.

[CACBCCCU]

Don't know if this is the vid for me to be talking about aether, but I brought it up before, so... the laws of physics do not change when the system isn't accelerating, and below I've suggested an etheric-seeming circular flow that galaxies and their stars is embedded within. Seems like the same rules apply, each galaxy is its own system, with stars as passengers. A cluster's etheric flow may rotate, but only with the pull and push of gravity, and it takes almost forever to make a rotation.

[CACBCCCU]

Still, the etheric part of the anticentrifugal antimatter idea I'm entertaining seems like a problem. Maybe instead there is a static-type wave property on the inter-cluster scale, and/or maybe about the same amount of antimatter is emitted to the outside but is swept away, and thus the relative accumulation of antimatter at the center.

[CACBCCCU]

The "spinning sea" space aspect of the picture I gave, as it seems to be interpretable to me, is problematic, because it's as if the "sea" is acting as an aether. The centifugal gradient is small compared to earth's gravity on land, we use a heliocentric gravitational reference whenever it fits the application, and the galaxies and stars in each cluster are carried along embedded in their orbit's correponding rotational "etheric" flows. One can't put one arm in-flow and another outside it.

[CACBCCCU]

FWIW, seems the antimatter flow hypothesis I've outlined below calls for the hypothetically-orbiting clusters to produce a spinning "Dirac sea" having an anticentrifugal effect upon antimatter, extracting it from the clusters.

[CACBCCCU]

Chandra's homepage has a much better image of this cluster pair in the slideshow "Chandra's 'Greatest Hits'". I guess they've figured out whatever was wrong with the image used here and there's no need to concern myself further with that aspect.  Still seems to me the two clusters are most likely orbiting each other, and antimatter from both clusters is being pushed toward the center, which seems to make some sense if antimatter has negative mass.

[CACBCCCU]

After looking over some of the specs a bit, it seems Chandra's signal processor has an event filter that triggers when an entire 3"x3" "island" of square CCD hits a threshold, to reject a presumably-associated error-inducing event. Seems the entire island is not participating in the x-ray imaging flare effects that, to me anyway, seem to be evident in this video, thus the trigger condition apparently needs to be redefined in spatial terms to be less than the entire island. JMO.

[CACBCCCU]

Chandra apparently uses a square array of tilted CCD sensors, if one source is to be believed (Advanced CCD Imaging Spectrometer (ACIS) Instrument on the Chandra.X-Ray Observatory). That doesn't surprise me, as it seems like some photon bouncing could be going into the x-ray image here. It's a very squarish sort of lens flare-out effect I think I'm seeing..

[CACBCCCU]

I asserted "two clusters nonetheless seem to have only passing familiarity with each other" based on the visible part of the image. Seems like the x-rays show gas heated indirectly by antimatter annihilations. Maybe antimatter is being drawn centrally, seems this would explain the severe brightness break in the center much better, but hey what do I know in the face of all these experts? I've got to laugh at something soon.

[CACBCCCU]

Without all the circles, arrows & computerized xray phantasmagoria, the two clusters nonetheless seem to have only passing familiarity with each other. What makes them look so collisionized to the experts is in the next installment, I guess. So they passed thru each other and by recorded speed (time lapse they left for chap. 3, I presume) we know they're moving in opposite directions and redshift says both are about same distance, but spectra fit an appendix best. Lotsa facetime/mouthmovin tho.

[nikolayzou]

Doesn't interact with light, well that is not entirely true, it is the medium that light transverses. Also, dark matter and dark energy are the same thing, it holds Galaxies together and also expands the universe at an accelerated rate.

[puncheex]

@nikolayzou: It both sucks and blows? Wow, versatile. Last I heard about Michaelson-Morley is that it pretty well dispelled any notion of a medium necessary to carry EM radiation. If it holds galaxies together, shouldn't it then be more prevalent in the galaxies?  How then does light seem top operate in the same way both inside and outside our galaxy?

[nikolayzou]

@puncheex The Michaelson-Morley error was to make a wrong assumption about the medium that light traverses. The earth doesn't move through dark energy, the earth is made from dark energy, when the earth moves, so does the dark energy.

[puncheex]

@nikolayzou: OK, explain to me exactly what the wrong assumption was, and why it was wrong. I assume you're up to it.

[nikolayzou]

@puncheex Light is constant regardless of what speed you are traveling, how is it possible to do any experiment to show light travels through a medium, you can't. The experiment didn't prove light doesn't need a medium to travel, they just couldn't prove that it did.

It all has to do with understanding how this medium works and interacts with matter. It is not the same as sound in air, or waves in water.

[puncheex]

@nikolayzou: "you just can't"? "...how is it possible to do any experiment to show light travels through a medium"? Try a glass of water. What they showed is that light cannot require a medium to travel through.

They showed that if there was such a medium that it must be traveling with the experiment through the universe, leading to ridiculous conclusions. Therefore there is not one.

Evidence free, your posting was.

[nikolayzou]

@puncheex That is correct, the medium (dark energy) is traveling with the experiment, spot on. This is possible because matter is made from dark energy. Dark energy makes up most of the universe, about 90% and science doesn't understand it. I wouldn't put any faith in experimental conclusions when science doesn't understand 90% of the universe. Michaelson-Morley experiment didn't prove anything, they gave up on trying to understand 90% of the universe.

[puncheex]

@nikolayzou: I'd give long odds that you're ascribing these fanciful things onto Dark Energy, which is derived in a totally different way, has long odds against it, but who knows? Maybe something in there clicks. Maybe. So you're going to give up on science until that day, I suppose. Holding galaxies together, though, is not dark energy's bag; it's more into repulsing galaxies apart.

[nikolayzou]

@puncheex I think I said before, dark energy and dark mater are the same thing. Anyway, you will see a big comeback in the aether theory.

I have a question for you. If the universe just comprised of ping pong balls all having the same amount of energy, what would you have?

[Promatheos]

Just remember relativity. It doesn't matter if you're in the milky way or in another galaxy. It looks like all other galaxies are coming to you and you are staying still. It's not like the center of the Universe happens to be the top of your head and now it's all rushing back at you. If the fabric of space is contracting then you simply can't define a point which the Universe is aiming at. All points are moving toward eachother.

[boycery]

Someone said it, sorry if you did, but I don't understand how that gas cloud has a greater mass than those stars/galaxies? And also, I think scientists should start telling religious fanatics that we think 'dark matter' is God. Then maybe we can get more funding

[1976muslim]

I wonder about this new knowledge about dark matter. As if Black Holes wer'nt complex enough.

[CACBCCCU]

Consider comparing this video with Hubble's "Ring of Dark Matter" video. In that video, the image is also supposed to show a dark matter response to a supposed collision, and the dark matter is supposedly spread out in a huge light-bending ring located midway between the separating clusters of bright masses. In this video they find the supposed dark matter stays with the two clusters of bright masses that collided. Complete lack of consistency in theories.

[CACBCCCU]

Still wondering how they gave the gas 90% of the total system mass. Is it relativistic mass? Must be fast gas molecules it it's 100 million degrees or whatever, so maybe that's it.

I thought the stars in a colliding pair of galaxies rarely get very close to each other, so where is all this hot gas supposed to be generated from and why is so little of it assumed to remain in the two clusters? Seems like all the cluster black hole accretion disks wouldn't even cover such an amount of gas mass.

[CACBCCCU]

I think you need black holes for an appreciable gravity lens effect, and when the matter is just a gas, the lens result is just like it's flat glass. Thus, I hereby pronounce this video idiotic.

[puncheex]

@CACBCCCU: Why? Gas has mass just as everything else does. Chunks of that gas can condense into stars; where do they get their mass if not the gas they are composed of? The lensing is a direct effect of the densities of the matter. Note that in the "Ring of Dark Matter" vid the lensed galaxy appears both inside and outside the ring, indicating that the major loci of density are a toroidal shape plus a bulge in the center.

[CACBCCCU]

They didn't explain how they arrived at the surprising belief that 90% of the matter of those two clusters is in the gas clouds between them, as if that belief should be easy to swallow. It's just more proof science doesn't understand galactic-scaled gravity or how to estimate mass at that distance, if you ask me.

[puncheex]

@CACBCCCU: Oh, I'll agree that they have a ways to go before they really understand galactic interactions. After all, it wasn't known there were any galaxies outside our own until just 80 years ago. They've made great strides in that time, but, yes, there is a way to go yet. So, do you favor them keeping everything secret until they do? That's not science; it grows best when the information is free. I see no better way to handle it than the way they have, and you are even a part of it.

[CACBCCCU]

@puncheex

"do you favor them keeping everything secret"

This is, believe it or not, appearing to me to be veering into politics, so

I'll avoid it.

You may have noted I'm not invariably a person possessing huge amounts of tact, to say the least. I'm too candid for many people and perhaps I should not have been so blunt before. In my "world," me being right routinely creates a great deal of professional quasi-rational backlash, so maybe you can see where I'm coming from.

[puncheex]

@CACBCCCU: Actually my suggestion about secrecy is the fantastic one, the one that was used to hide the particulars of atomic energy, and one that failed in its aim hopelessly. It certainly prolonged the cold war. Therefore I reject it.

That leaves us with astronomy growing in awareness of galactic and intergalactic science, and throwing off ideas and hypothesize with abandon.

[puncheex]

"Still wondering how they gave the gas 90% of the total system mass. Is it relativistic mass?" That's just the thing; they don't know what dark matter is. It's not a gas in the classical sense, because it has no friction against real gas. That's why it blasted on ahead of the collision along with the stars; only the intergalactic gases collided.

That's just the thing; they don't know what dark matter is. It's not a gas in the classical sense, because it has no friction against real gas. ...

[puncheex]

... There's a lot more out there than accretion disks account for. So when two galaxies collide, the chief interaction is gas being slowed from high galactic velocity to zero relative and giving off huge amounts of heat in friction and KE conversion.

[puncheex]

... I'm so lad to meet someone who is "so routinely right"; I'm quite often wrong. But are there holes in the above argument about the gas withing galaxies and how the bullet shows something unusual about the mass distribution of the colliding galaxies?

(Last of 4 parts)

[CACBCCCU]

@puncheex

It helps to have the best tools for whatever it is one is trying to do, but some people are paid to be wrong in a highly-authoritative manner, and others have situations much different than that. Anyway, there's really not anything "routine" about what I was mentioning unless one wants to ignore many years of hard preparation.

[puncheex]

@CACBCCCU: You used the word routine with respect to your ability to always be right first, not I. What sort of preparation are you talking about? The rest of this crackles of conspiracy theory.

[CACBCCCU]

@puncheex The routine part was supposed to be the backlash part, IOW, when I'm right in an assertion (not unusual, believe it or not) the backlash process is routine, to be expected, a regular aspect, a part of the game, why it's not really fun. It routinely happens because I've been doing the same things for decades, I learn from my mistakes. Still doing it because I can lay it down with the best.

[CACBCCCU]

@puncheex "are there holes in the above argument about the gas within galaxies and how the bullet shows something unusual about the mass distribution of the colliding galaxies"

Maybe it involves hypothetical antimatter accumulation between clusters and a hypothetical deflective effect on photons passing between the clusters. I have specific reasons for believing the lensing and mass estimates are off. The reasons are not on this page, I'll reiterate them if asked. Have a great evening, btw.

[CACBCCCU]

@puncheex

Any theories on why the brightest part of the red spots is so angular? Seems like heavy flaring, maybe some modulo overflow bug in the wavefront reconstruction algorithm? Wild guesses, all I have for that.

[puncheex]

@CACBCCCU: I'd say red/blue shift would differentiate that difference. But we're out beyond my expertise, so all I can do is parrot some other source. Should know better than to argue with someone who is always right, anyway. :)

[CACBCCCU]

@puncheex

"I'd say red/blue shift would differentiate that difference"

Thanks for refraining.

If they're circling and fairly close together, my bet would be that's a really hard call at this point. The collision part is supposed to fly unsupported, that's bothersome. Maybe they're crossing fairly close together but didn't collide. No reason to think otherwise except words. Why show any pictures at all? That was the next thought, just lay it down in expert tones like group brainiac.

[CACBCCCU]

@puncheex It's like I can tell Changra's square CCD array is rotated 45 degrees from the image frame. A small differential-image reorientation of chandra combined with a software fix would cancel it out, I suppose. It's as if light is reflecting back and forth between the CCD and something else inside Chandra. Wild guess: it's probably an x-ray freq translator assy similar to a focused gieger counter mesh. I'll read up on it more, to verify.

[CACBCCCU]

@puncheex This seems like a decent question: What's shown, if not that which the video's experts collectively describe as being shown?

Maybe the clusters are actually circling around each other, rather than being in a state of post-passing-through each other?

[fishytypewriter]

Oh my God, Clowe is one of my professors! this is great! I love NOVA . =D

[gaynorglowellxsingh]

I have a question. Their seems to be a lot of mass thats missing from our universe. We look for all of the possable ways that could explain it. Isin't radiation mass, it's accelerated protons, neutrons, electrons, photons and maby even down to the quantum level. Do we calculate this as mass in the missing mass theory. See my video about dark matter.

[robertwc82]

is dark matter something different to anti-matter?

ive heard that anti matter photons can be produced in a lab and that they utalize anti-matter in those cat scan machines (maybe not cat scan could be MRI's but its one of those imaging machines for hospitals)

[Predadragon]

@robertwc82 Yes, dark matter is inferred only from the gravitational pull it exerts on nearby galaxies, but since it doesn't emit any form of radiation, we can't detect it directly, only it's gravitational pull, much like black holes, only much less strikingly. Anti-matter on the other hand has been detected, and the human race has created up to a teaspoon of the stuff, considering it may not have existed in the universe since the big bang. It is simply normal matter with opposite charge.

[robertwc82]

@Predadragon T.Y

[Nemesis2599]

4:10 - "Dark Matter is basically the glue that holds all the large structures in the universe together."

Such as galaxies? Let's not forget that there is large evidence supporting that every galaxy has a black hole at its center. Sagittarius A* in our own galaxy is believed to house a supermassive black hole of around 3 to 5 million solar masses, to me that would seem to produce sufficient gravity to keep the galaxy together. Dark Matter may explain other things, but not galaxies.

[Predadragon]

@Nemesis2599 The supermassive black hole theory, which has now been confirmed, even in conjunction with current calculations for the gravitational potential of all the gas and stellar material in the Milky Way still account for around 5% of the gravity acting upon the nearby galaxies such as the Large and Small magellanic cloud. Good hypothesis, i considered it too, but it's just not enough. The dark matter halo idea is the only one to explain it right now.

[puncheex]

@Nemesis2599: Yes. Including galaxies. The astronomers certainly do recognize the supermassive black holes, and yet there is more required. The galaxies are far too large for their mutual gravitation, with even the supermassive assist, to explain.

[TyTyMcGinty]

In keeping with the idea that the universe is fluid, I can imagine that the dark matter that acts as a cohesive force preventing galaxies from disassembling is not unlike the geltinous mold that holds jellyfish together. Kind of like when you spit phlegm into a body of water it still maintains its shape.

[darkprimordialspirit]

@TyTyMcGinty

Your allusion doesn't quite fit.

Mathematically Breakthrough

It is now mathematically proven that the decelerating force that affected the Pioneer probes and the accelerating force that had caused many Fly-by anomalies:

1.) Both affect the Earth (and the planets) as well, - and with full force.

2.) Automatically equalize each other (when affecting the planets).

How can two galaxy collide when they are supposed to be moving away from each other?

They are both moving away from the big bang source - the other galaxy is moving faster and it overtakes the other galaxy, it means if you align them you will find the center of the big bang.

[Promatheos]

There is no center of the big bang. It wasn't a bang out in empty space somewhere, but space itself expanded so that every point in space can validly be called the center. That is a large part of what relativity says.

And galaxies can collide though space is expanding because gravity is more powerful than the repulsive force of dark energy where there is a lot of matter.

[ShowinYaHow]

@Promatheos

Actually... for the Big bang to happen... IT had to happen somewhere... If everything is expanding outwards, at some point in the Universe, there has to be some point that is not expanding anywhere, or where Everything is expanding away from that point.

[Promatheos]

@ShowinYaHow

What you say feels intuitively right because we can only picture the big bang as some kind of expanding sphere. But that is only a 3 dimensional representation of what happened. Human minds can not comprehend the reality of it. The Universe doesn't have an edge and without an edge it has no center.

It's curious that you say "it had to happen somewhere" when actually anything that could be called a "somewhere" came only after the big bang happened.

[ShowinYaHow]

@Promatheos I understand that that is no "edge" of space... but if the Universe is constantly expanding... What would it be like if it was all collapsing? What if Dark Energy had a reverse effect, and pulled the Universe together instead of pushed it apart? Where would It all Aim too?

[puncheex]

@ShowinYaHow: Rat cheer.

[sabin15]

Another pbs special I watched shoed that every solar system revolves around a black hole, even ours. Also, every solar system is trying to eat one another. So, I am guessing one day the universe will just be one big solar system.and then the main black hole will eventually eat that and nothing will exist againhmm

[puncheex]

@sabin15: That's every galaxy, not solar system. Our solar system orbits around the sun, ever since Copernicus, leastwise. Your idea is one theory about the end, but it doesn't end there, because Black Holes slowly evaporate.

[okturus]

Cosmology at best is a pseudo-science i'm beginning to believe. The narrative these cosmologists present is rife with gaps and wholes. The big bang theory requires just as much a leap of faith as anything else i've wanted to believe.

[Predadragon]

@okturus I'd disagree. With cosmology, we have an existant, if distant evidential basis, and the strand from which we draw our theories are assembled carefully using the most complex and surgical mathematics our race has seen. Cosmology is the science, encompassing physics, chemistry, even biology, which i believe, will lead us into the 'mind of God', as einstein put it.

[puncheex]

@okturus: I think that is only because you're not a cosmologist.

[MortalBeeyach]

If you think about the universe, you see that light moves in all directions at 669,600,000 miles per hour. So why can't we see all the out to the edge of the universe? Light hasn't gotten there yet. So in theory, why do we have voids in the universe? Shouldn't all light have traveled to everything between galaxies by now? This is where dark matter comes in. We say that, in theory, there must be some kind of particle that pertains no light: i.e., "dark matter".

[kshackleton]

It's not the light getting to the edge of the universe that allows us to see it. It's the light which returns to us and goes into our eye that allows you to see. We see objects as they were when the light left that object, we don't see it until the light enters our eye.

[pbsandcspanwatchit]

You guys this is a BIG subject,google dark matter and the larger mystery dark energy and read several results, say at least 5-6 each, then you may understand a little better, you will see why these subjects are of the BIGGEST Mystery in modern cosmology and particle physics as lifted from wiki article below

"Only about 4%of the total energy density in the universe (as inferred from gravitational effects)can be seen directly.(Comment from me, that 4% is us!All the planets,stars,ect, only 4%!)

[pbsandcspanwatchit]

only 4% can be seen.About 22% is thought to be composed of dark matter.The remaining 74% is thought to be dark energy, an even stranger component, distributed diffusely in space.

[4] Determining the nature of this missing mass is one of the most important problems in modern cosmology and particle physics. 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."

[pbsandcspanwatchit]

When I first read of dark matter and mysterious dark energy evidenced by Chandra I was immediately was reminded of the begining of my BIBLE,

Gen 1:1 In the beginning God created the heavens and the earth. Gen 1:2 The earth was empty, a formless mass cloaked in darkness. And the Spirit of God was hovering over its surface.

I believe the "dark" energy that makes up est. 74% to 85% of the Universe, % depending on which scientific article you read is the SPIRIT of God. REALLY!

[Tatarize]

You worship thoughtless particles? Oh, how the mighty have fallen. I remember when God controlled the heavens and regulated every facet of the cosmos and provided the regularity to all that was regular. Now it seems God is down to invisible exotic matter halos. -- I hope neutrons grant your wishes cuz dark matter don't answer your prayers. Oh, and Deepak is full of shit.

[pbsandcspanwatchit]

Oh God forbid! I do not worship creation I worship the one and true God,creater of everything and Jesus Christ of Nazareth His only SON!! God said,I am that I am, He is omnipresent in anything that exists seen or unseen. Except the evil one and his fallen "angels".scientists cannot explain this mysterious "dark matter and dark energy" and you don't think GOd almighty's presense,spirit is in that? but I don't worship that, I am redeemed by the blood of Jesus Christ!

[pbsandcspanwatchit]

and I totally agree with you on deepak,totally! I can't even stand to look or listen to him.

ck out my morning praise and worship playlist, and my Gospel list, God bless!!

[matttheobscure13]

yeah, there's something in the universe that we can't fully explain, so it MUST be God.

[pbsandcspanwatchit]

Hey there! You got a better answer? :)

[MrKevMan]

Uhh, yea. Really. You fruitcake!

[pbsandcspanwatchit]

well MrKevMan, like I posted before, Have you got a better answer? Explain this

Colossians 1:16 For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether [they be] thrones, or dominions, or principalities, or powers: all things were created by him, and for him:

this is from the New Testament so how could they even know there were invisible things 2000 yrs ago? think about it, and may God bless you richly today!!

[MrKevMan]

Yes, its mumbo jumbo. Interestingly enough, ancient greek philosophers had theories of the atom and the power it could unleash when split. This was pre bible and 1000X more accurate than some vauge writings by a superstitious people.

[slcricket]

have they found any evidence for dark matter closer by, say in our own solar system? why is this sort of evidence only visible in distant galaxies?

[lostismyconstent]

so do they think dark matter is some sort of compound or a whole new element all together?

[lmusho]

I think we are getting ahead of our selves, how can you say what causes gravity if you cant explain what gravity is.

[lostismyconstent]

i think you have it backwords, they know what gravity is, a scientific law, but they dont know exactly what causes. (last i heard they thought it was some sort of partical but who really knows?) they have, however accepted gravity as a constent that can fit the general rule of more matter=more gravity. perhaps it has something to do with density as well tho in reference to the gas vs solid and their gravitational pulls.

[markedwardsuk]

I think energy and mass are separate, but they interact. At the quantum energy wraps around mass, this means that we can get rid of the neutron, there is not such thing as positive and negative, mass either needs energy or does not it has the same effect. Just in case we have to rewrite the laws of physics and Einstein and Rutherford were wrong this is a fab alternative.

[Joannalick]

I enjoy watching and reading about this sort of thing. But what I don't understand is, how do they know so much about dark matter, for example, they said more matter = more gravity, if they don't know what it is?

[SuperFinGuy]

Btw, ask a regular physicists what gravity is or what it is made of and what drives electrons. They won't have an answer for you.

[puncheex]

@SuperFinGuy: And so? They really aren't omniscient? Damn, I thought it was always stapled to the back of the diploma.

[SuperFinGuy]

This is out context, the reason there is more gravitational energy among the galaxies is because galaxies/quasars are gravity wells and although they are less massive than the gas clouds their matter is in greater acceleration. So the extra substance in play here is gravity.

[tinman652]

you can't really be that dense 14words14words

[ghendiRo]

A 10 year old child can find better explanations that dark mater.

But some people actualy know what's going on. Simple put is electricity in space doing it's job, we have an electric universe out there. 99.99 is plasma, perfect electricity conductor. There are birkeland currents flows on incredible distances generating electric fields, and no black holes but most like highschool science.

Thatose are keeping galaxies together not invisible undentified gizmos, can scientists be more ignorant?

[samhellion]

Its sad today scientics are still making up ship.

Some msyterious gremlin to explain our not knowing.

[spase667]

What the Hell are you talking about? Did you not hear them explicitly say that they don't know what dark matter is? "Dark matter" is just a word to identify that vast category of stuff that currently evades our knowledge. Scientists aren't making shit up, they're trying to figure it out.

[anphelps27]

@spase667 I agree. The big bang theory is just that, A THEORY, not a proven fact. Many astronomers and astrophysists come to the conclusion that our universe was the work of intelligent design.

[anphelps27]

@spase667 I agree. The big bang theory is just that, A THEORY, not a proven fact. Many astronomers and astrophysicists come to the conclusion that our universe was the work of intelligent design.

@anphelps27 Which is a complete cop-out. Why INTELLIGENT design? How do you know we're not just snot from some greater being's nose?

Because you're coloured by belief in what makes you comfortable, just as they are.

@skinned66 Dude, I am not comfortable believing in what I believe. Being an atheist would be much more comfortable. That way I would have no consequence for anything I do as long as I get away with it.

[skinned66]

@anphelps27 There are plenty of far more mundane and worldy consequences for your actions to encourage you to have a conscience and be good to others. But if attrition is what keeps you from being a sociopath, then by all means keep reaching for the sky.

@skinned66 Shut up dude, and you can stop with the wanna be intellectual condescending speech. You are a hypocrit!! I believe something cause its comfortable to me? Would you say that that goes for every human being on the planet? Never did I say I wanted to be a sociopath, but simply that we have consequences for our actions. Meaning, things that I might think are wrong you might not, but because of my belief I try not to do them. Cont....

@anphelps27 Wannabe intellectual? How amusing - remember where you are talking about intelligent design in a comment section about dark matter. I understand the context so you don't need to explain it - but talk about an unproven theory with even less evidence than the big bang.

I'm not a hypocrite; I dare say you are. So that's where this exchange ends; go back to your bottle of warm milk. But by all means continue, maybe someone else will be interested in the rest of what you have to say.

@skinned66 Never once did I say anything about your belief structure. You said something about mine. I know about dark. It to is more or less a theory. And I never made any claim here. All I said is that there are a lot of astronomers and astrophysicists that conclude intelligent design. Dark matter could have been part of that design. And I dont even like milk. Educate yourself a little more and get back to me.

@skinned66 And another thing Einstein, you can be a Christian and still appreciate science.

@anphelps27 "...and another thing, Einstein (what does that do?), you can be a Christian and still appreciate science.

Not if my theory makes creationism a cosmic joke among jokes.

@skinned66 People like you are so quick to tell a Christian or someone of any religion for that matter that they judge others cause others do not think like us, but by your comment about me reaching for the sky, would you say that to someone that thinks like you? Wake up dude. Stop being a hypocrite!!! Just cause someone does not think like you does not make them less intelligent. And before you spout off at the mouth again, I have my degree in physics. What is you area of expertise?

@anphelps27 ...dude.

As an agnostic raised in Christianity, I am desperate for scientific knowledge.

I wish Nova would do an episode on alternative theories, like the Electric Universe theory.
