Abstract:
In this talk I will focus on asking and answering the following questions: (1) What is a black hole? (2) Can astrophysical black holes be formed in the physical universe? (3) How can we prove that what we call astrophysical black holes are really black holes? (4) Do we have sufficient evidence to claim the existence of astrophysical black holes in the physical universe? (5) Will all matter in the universe eventually fall into black holes?
