There is still something that I don't understand.
Some people claim that there cannot be "real" black holes in the universe because it would take an infinite amount of time - in the outside, normal space - for the singularity to form. Since the age of the universe is generally assumed to be finite, no such infinite amount of time has ever gone by. Therefore there are no real black holes in the universe.
(I hope I got this right...)
My question is: if there can't be any real black holes in the universe - only objects *on the verge of becoming* black holes, after an infinite amount of time -, then a micro-black hole would never actually form, and thus it would never actually evaporate.
Am I right, or am I way off track?...
