What happened to the black hole firewall theory? Back in 2012, some physicists apparently came up with strong evidence that one of three things must be wrong for black holes to work the way we thought they did:
- the Equivalence Principle or
- the Event Horizon.
It seems that for a week the media had a flurry of reports that physicists including Stephen Hawking were dumping the event horizon for things like an "apparent horizon" and then... silence. I haven't heard anything about the firewall theory since.
Are physicists still trying to work out a solution? Did someone realize that the theory was flawed in some way? It seemed like a big deal at the time so I find it odd that it seems that no one is talking about it right now, although that might just be my over-reliance on general media for physics news.
