What is the current evidence for the existence of black holes? What is the current evidence for the Big Bang Theory? Are these two Qs related to the discovery of the Top Quark?

Certain X-ray emitting astronomical objects are the best evidence for the existence of black holes. Actually there are lots of clues in astronomy. The microwave background radiation is the strongest evidence for the Big Bang theory, but there is other evidence in the observed chemical composition of the universe, and of course the redshift of distant galaxies. And no, this has nothing to do with the top quark.
