How Would an Astronaut Falling Into a Black Hole Die?

ananyo writes "According to the accepted account, an astronaut falling into a black hole would be ripped apart, and his remnants crushed as they plunged into the black hole's infinitely dense core. Calculations by Joseph Polchinski, a string theorist at the Kavli Institute for Theoretical Physics in Santa Barbara, California, though, point to a different end: quantum effects turn the event horizon into a seething maelstrom of particles and anyone who fell in would hit a wall of fire and be burned to a crisp in an instant. There's one problem with the firewall theory. If Polchinski is right, then either general relativity or quantum mechanics is wrong and his work has triggered a mini-crisis in theoretical physics."

    Unicorns would stampede the astronaut as he enters the event horizon. There's one problem with the unicorn theory. If I'm right, then either general relativity or quantum mechanics is wrong.

    well, technically, wouldn't the convicted murder BECOME an astronaut by definition the moment we shot him into space?

    slashdot is really provoking the deep questions today.

    Leave your crappy sitcom references at the door and let the adults talk.

    Take the time to read too, you might learn something that isn't some comic book fantasy.

    How would he die?

    Of old age, on the multimillion year journey to the nearest black hole, I suppose.

    But don't let me be the one to interrupt your little rec time, on the holodeck. ;-)

    If the astronaut gets across the event horizon, then he will never die relative to us. So, there really isn't a problem here as far as I can tell.

    Heck, considering what we know about the locations of black holes and the speed of manmade spacefcraft, old age will probably kill you before you get close enough to notice the gravity.

    It will probably not answer your question, but it's about black holes and they're very cool! Or hot. Depending on the observer ;)
