Does dark matter exist?
Dark matter has been suggested as a solution to the galaxy rotation problem
where individual stars don't seem to rotate the way Newton's laws would predict. Now, some scientists are saying that observations fit with Einstein's general relativity, without any dark matter needed. I just find it amazing that no one has tried this yet.

It ain't so dark anymore.
Dark matter seems poised to assume its place among those astronomical phenomena that were predicted to exist before being observed. The planet Neptune
and black holes
to mention two of them. The last 100 years have really been a boom time for astronomy, and they're not slowing down.
