It's a sad day for science fiction when even Steven Hawking has give up his previous theory about black holes. He now says that he is convinced that matter sucked into a black hole is kept and eventually spat back out at the end of the black hole's existence. This is in contrast to his previous view that allowed for the possibility that a black hole could serve as a gateway to other universes.
Black holes have, of course, been the fodder for some great science fiction and I'm sure they'll continue to be. But, when one of the world's leading scientists has given up the hope of such a theory, it becomes much more science fantasy rather than science fiction.
