: In my opinion singularities cannot possibly exist. It would take an infinite amount of time to crush something into infinite density. An object could just get smaller and smaller no matter at what speed it collapses without reaching 0 size. You cannot possibly collapse an object out of existence, maybe in another universe that has different laws, but not in our universe. Tell me what you think, I would be glad to read your opinions.

Black holes exist in the infinite. Reletivity states that as an object approaches the schwartzchild radius time slows down accoring to the twins paradox. At the event horizon the temperal distortion becomes infinite, and therefore, the star could take an infinitley long time to become infinitly dense and still exist in this universe. Check out "About Time" by Paul Davies for a good description of black holes and other physics related materials.
