| According to Copenhagen, an observation is an action that changes

| information escaped the black hole. Bob fails, Alice sees the
| interference pattern.
|
| According to many-worlds, a measurement doesn't change the state,
| it changes the observer via entanglement. So Bob would observe
| the path of the particle and not see the interference pattern.
| Alice, completely isolated from Bob, would see the interference
| pattern. The two seeing different things doesn't seem so odd -
| causality and black holes have a funky relationship anyway.
|
| I'm also curious about the claim that "The laws of physics behave
| the same just inside the horizon as outside". What backs that up?
