Talk:Dark matter

Removed statement that existence or non-existence of dark matter contradicts big bang. Dark matter actually has very little to do with whether big bang is true or not.

The article at Big Bang theory speaks of a dark matter problem; you may want to correct that if you're better informed than the author. Mkweise 13:05 Feb 16, 2003 (UTC)

Did so. What I suspect that the author was referring to is the fact that dark matter *helps* the big bang theory. During the 1970's, there were a number of problems (mostly deuterium abundances) that have been nicely resolved by assuming that dark matter exists.

I vaguely remember that some time in the 1990s, new observations led to the stunning (at the time) conclusion that more than 90% of the universe's matter is dark. IIRC, some previously favored theories were essentially scrapped due to that - I don't remember specifically what theories, but I think it led to a change in the estimated age of the universe by many orders of magnitude.
