(Sorry, I couldn't resist.)
It seems that one of our most cherished beliefs about black holes has been disproved. Stephen Hawking himself delivers the bad news:
"I'm sorry to disappoint science fiction fans, but if information is preserved there is no possibility of using black holes to travel to other universes," he said. "If you jump into a black hole, your mass energy will be returned to our universe, but in a mangled form, which contains the information about what you were like, but in an unrecognizable state."
Another consequence of his new calculations, Dr. Hawking said, is that there is no baby universe branching off from our own inside the black hole, as some theorists, including himself, have speculated.
Well, this doesn't completely disprove the selfish biocosm hypothesis, as expounded by James N. Gardner in his book, Biocosm. But it looks as though intelligence-friendly universes are going to have to find a different way to reproduce. Black holes won't cut it.
