Stephen Hawking is one of the creators of black hole theory using relativistic physics. (Actually, it would have been possible to come up with a black hole theory using the old Newtonian physics, but nobody ever bothered to.) Hawking has actually become quite the celebrity from his work, and he even appeared in an episode of Star Trek: The Next Generation. He’s one of the most easily recognized scientists in the world.

Now Hawking has rethought it and declared black holes do not exist. A standard feature of science fiction has vanished, as if it had fallen into . . . well, we’ll think of something. Easy for Hawking to say—sorry I was wrong about what’s made me famous over the past few decades, next I’ll invent some other impossible things for you yokels to believe in.
