Dark Matter 3D Map

Video Description:
COSMOS Video News Release
For the first time ever, astronomers have been creating a three—dimensional map of how the dark matter is distributed across the Universe. An international team of scientists, among them groups from Marseille, the Max-Planck Institutes and Paris have been using data from the NASA/ESA Hubble Space Telescope. The results are published in nature online of 8 January 2007, and at the meeting of the American Astronomical Society in Seattle. This Video News Release discussed this discovery.

what's the ... ( 4 months ago by suril22)

what's the difference between dark matter and dark energy? A reply would be greatly appreciated.

Dark Matter is ... ( 4 months ago by schmitz9066)

Dark Matter is material that helps keep the galaxy gravitationally bound. Dark energy helps accelerate the expansion of the universe by increasing the distances between the superclusters on a larger scale.

good explaination...thank you!

the main thing is ... ( 4 months ago by flc735)

the main thing is dark is code name for unknown. dark matter is matter that we don't know what it is (because we can't see it). and dark energy is energy that we can't observe. dark matter (just like matter) has a gravatational force and gravity does effect light (just very very slightly).

Yes, gravity is the only reason we know something exists in those areas. Since we can't see what is exerting that gravity, we call it 'dark matter'.

ohh i would say this existence is very much intentional and has been created by a race of creatures outside what we can comprehend within our limited 3/4 dimentional awareness, however what the end result is or the purpose will elude us forever.

The reason a theory ... ( 1 month ago by Impossiboss)

The reason a theory for dark matter was brought up is because there was more gravitational force in the universe than the matter that exists could produce. The matter we can observe only creates 1/4th of it. And the reason we cant go get handfuls of dark matter in space is because it isn't dense at all. But because there are such vast distances its lack of density is made up by the amount of space it occupies.
(First Comment, followed by a second.)

But two things I ... ( 1 month ago by Impossiboss)

But two things I thought of.
I havn't thought this one out so it probobly has a fundamental flaw I'm not considering : What is things are just 3/4ths heavier than we thought?
The other being : What if the extra gravity comes from black holes? We can't tell exactly what a black hole is made up of and we don't know they they have a definite level of density or what that level of density is.
(Second comment, followed by a third.)
(I just thought of something else haha.)

In between 0 and 1 there is an infinite amount of numbers.
0.12 0.112 0.1112 0.11112 It goes on forever.
So does matter have a maximum density? A point in which it is so dense it can no longer be compacted? If matter is made of things with a definite mass that cant be lessened then yes. But since all things are relative to math, and math states that it goes on forever. Could matter not be compacted forever? Even the smallest quarks being pushed infinitely smaller than their origninal size?

Our Universie is finite, therefore that which is in it must also be finite.

Thanks, yeah I've never read any papers so I really lack on knowing the principles and theories. I try to do it all through speculation.

Stupid scientist waist of tax money.
It'll probably take them another 80years to figure out the speed of light and realize dark matter doesn't exist.
I'm just afraid there going to make this bullshit another fact. lol

Look at it this way ... ( 2 weeks ago by jem1985)

Look at it this way. Dark matter is the product of what we cannot explain. It is infinitely dense whilst having no mass what so ever.
Because it has no mass, we cannot obtain it to study (yet).
I believe Dark Matter is the product that held the universe together PRIOR to the big bang and is also the product that directs gravity.
If we could understand how "time" and "gravity" are linked together then we could understand what forces act as the glue that hold our universe together. cont...

Array ( 2 weeks ago by jem1985)

...cont
My point is that the universe has a timeline and must have started at ONE particular second in time.
Dark Matter is the force that unleashed the big bang. Therefore it must be the force that shapes our universe today.
Ask yourself when we will discover the origin of time and i believe this will be the age when we will discover the origin of Dark Matter.
Please post a response to my theory as it is not educated and id love to hear more opinions. Just a hunch :D

Dark matter, as ... ( 2 weeks ago by TawntheAtheist)

Dark matter, as science currently understands it, is not infinitely dense and lacking mass.
In fact that is the only thing we really know about dark matter - it has mass. Yet it seems to have no other intereactions with normal matter other than its gravitational pull.. we can only 'see' dark matter through its gravitational lensing effect - a result of mass.

Perhaps you're confusing dark matter with dark energy?

"Why would dark matter distort light? Would that mean it has gravitational pull?"
Correct. ..and that is all it appears to have.
