http://www.physorg.com/news8932.html

Clues revealed by the recently sharpened view of the Hubble Space
Telescope have allowed astronomers to map the location of invisible
"dark matter" in unprecedented detail in two very young galaxy
clusters. A Johns Hopkins University-Space Telescope Science Institute
team reports its findings in the December issue of Astrophysical
Journal.

Wow, that will interest some guys in Amsterdam computation center ;-)

How could you expect the bipolar guy on the airline who was gunned down
to have taken his medicine?? He was nuts! Bipolar!!!!!! He shudda
been strapped to a nuthouse bed and given a lithium drip!!!!!
Self-medication???? Self-reference????? Hofstadter?????? Sheesh!!!!!!
Modern civilization. Unsolvable problems. Godel. No way to joots.
No way to joots. No way to joots. No way to joots.

Have a nice day.

That would NEVER be possible because by definition of universe the computers
would need to simulate themselves.

Not likely. They can't even simulate dirt. After they simulate dirt,
ask them to simulate an apple seed.

I think what is significant in the article is that it shows that normal
matter gravitationally attracts the dark matter which then adds to the
total matter in the galaxy.

A way this could happen is if space itself were composed of ordinary
matter. It would be uniformly distributed and so wouldn't change the
attraction generated by real masses like the planets, etc. However,
since space consists of ordinary matter, it is gravitationally
attracted to the planets and causes the density of space to increase
around the planet. This increased density actually adds effective
gravitational mass to the planet. The compressed space around Earth,
might add 90% to the overall gravitational mass of the Earth. The added
mass is due to compressed space compared to space which has no
gravitational objects in it.

My description of space as being composed of ordinary matter
(neutrons/neutrinos or some bounded combination of proton/electron) can
be found in my theory of everything at:
