timmy- i'm surprised you haven't commented on this story yet? Hawking Upends Own Theory on Black Holes By Jim Dee July 22, 2004 10:20AM Renowned astrophysicist Stephen Hawking admitted that his 30-tear-old theory about black holes was wrong. The celestial vortexes, formed by collapsing stars, release some particles into space when they disintegrate after all. Professor Stephen Hawking, a giant of astrophysics who has helped explain the origins of the universe, admitted yesterday his pioneering 1974 work on energy-sucking black holes was flawed. Hawking, 62, a mathematician at England's Cambridge University who's been wheelchair-bound since being paralyzed by amyotrophic lateral sclerosis in the 1970s, conceded black holes don't fully devour everything. Instead, he said that as they eventually disintegrate, they spit out sub-atomic particles back into space that may carry clues to the inner working of the densely-packed dead stars. Hawking also retracted his earlier belief -- popularized by Hollywood -- that vanishing matter in black holes might travel to parallel universes. "I'm sorry to disappoint science fiction fans," Hawking, speaking via a specially-constructed computer, told a conference of 600 scientists from 48 countries, "but ... there is no possibility of using black holes to travel to other universes. "If you jump into a black hole, your mass energy will be returned to our universe, but in a mangled form," he said, drawing laughter from the crowd. "It's great to solve a problem that has been troubling me for nearly 30 years, even though the answer is less exciting than the alternative I suggested," added Hawking. Hawking's U-turn lost him a 1997 bet with California Institute of Technology physicist John Preskill. Yesterday he gave Preskill his prize: a copy of "Total Baseball, The Ultimate Baseball Encyclopedia," which he had specially flown over from America.
