Light and dark matter in the universe

This simulation follows the growth of density perturbations in both gas and dark matter components in a volume 1 billion light years on a side beginning shortly after the Big Bang and evolved to half the present age of the universe. It calculates the gravitational clumping of intergalactic gas and dark matter modeled using a computational grid of 64 billion cells and 64 billion dark matter particles. The simulation uses a computational grid of 4096^3 cells and took over 4,000,000 CPU hours to complete. Read more: http://www.anl.gov/Media_Center/News/2010/news100104.html

this is infinitely rudimentary, but good work.

Too hard to see video !

It is in fact something natural as a living thing...that's where we are into...just a living thing ..

I can't really tell you what links to follow. Michio Kaku is a great physicist to listen too on many subjects including Dark Matter, also if I can remember my physic's prof's friend that came and gave a speech on her research on it I'll post that name so you can youtube or google that. But it doesn't have mass because it isn't made of a detectable particle. and mass, is a property of the particles you are made of, so you could be correct in that it has some higher dimensional masslike particles

I'm curious now. Do you have any links to recent theories on dark matter? I'm pretty much a layman with a strong interest in astrophysics, but I always assumed dark matter had to have mass simply because it is detected gravitationally. I've always entertained the idea that it is matter "deeper" into a fourth spatial dimension, so just out of phase with what we can detect directly but still very much present, as evidenced by its gravitational influence.

[iansull]

what are you even TALKING about, "LOOKinsideyurSELF"?

[CptBoots]

However, we can map Dark matter by observing it's gravitational influence on surrounding space. So in short, Dark Matter is Non-Baryonic, massless matter with the gravitational properties of a mass having (or Baryonic) substance. Though I do get the biblical allusion you were making. I'm just being asinine .

[CptBoots]

I believe you are confused as to the proper context for discussing dark matter. Dark matter refers to matter which is non-baryonic (i.e. not comprised of particles which we can actively detect.) Because of this they do not have the properties which would allow for them to reflect, or emit light, which is a form of manipulated photon streams (i.e. Baryonic)

[LOOKinsideyurSELF]

unless im confused, there is no dark matter,Ther's only light From The SON dark does not matter for it comprehends light not.
