Did Stephen Hawking just kill the concept of a black hole?

submitted by radx

1 decade 9 months 3 weeks ago

Stephen Hawking replaces the event horizon with his concept of an apparent horizon, based on the idea that the evaporation of a black hole allows previously trapped particles to escape after all. So the more ephemeral apparent horizon is similar to an event horizon but with an expiration date attached to it.

No event horizon, no classical black hole. It's still there, but the inclusion of quantum mechanics requires a revision of the concept of an event horizon.

So he didn't kill it, he didn't steal it, he just illuminated shortcomings of current theories. Shit got more complicated. Again.

Oh, and he killed firewalls in the process, apparently.

…no conjecture here!

so, we can just call them temporary very-dark-gray-holes.

He questions himself. A great scientist. Amazing. Very few exist.

quote from a friend of mine:

i just love that the scientist that is largely responsible for the theory, and has been working on it for 20 years, has stood up and said, nup, we got it wrong, now it's this

take that, religion

He questions himself. A great scientist. Amazing. Very few exist.

Religious people would say smuggly, "Of course he changed his mind, he's human -- our God got it right the first time. Take that science!"
