Black holes and warped spacetime|
Nothing in physics can prevent some stars and other systems from experiencing continued
gravitational collapse, resulting in a "black hole" that is cut off from communication with
the rest of the universe. For nearly a century this fact has often disturbed, confused, and
puzzled physicists, including Einstein himself, whose general relativity theory accounts for
the existence and properties of these strange objects. This talk will begin by sketching
the conceptual framework of Einstein's warped spacetime theory of gravity, and will then
describe the nature of black holes and the difficulty and success physicists experienced in
coming to terms with them, including a bit of psychoanalysis. That will set us up to explain
the famous discovery of Hawking that black holes can evaporate, and the perplexing puzzles of quantum gravity raised by the existence of black holes.
