Do black holes really exist?

Probably. Astronomers have discovered quite a few objects that can only be explained as black holes. These objects are dark, so we cannot see them, but they exert a powerful influence on the stars, gas, and even space around them. These objects are so dark, dense, and heavy that they must be either black holes or something even more exotic.
