When I say event horizon I mean the Schwarzschild radius for a simple isolated non rotating black hole. That is the point at which no further communication to a distant observer is possible. This is more complex in the Kerr or rotating caseI mean that as well. Computation of the event horizon is more complicated given charge and rotation and such, but in the end the concept is the same. If the gravity at the horizon is 1550g's, then communication is possible by an object which has finite force enough to accelerate it at 2000 g's, and it thus isn't an event horizon. Emphasis on 'possible' above.

Kind of over my head. I know the firewall as one possible solution to a unitarity paradox. I'm only a novice at quantum field theory, so I won't be much use in the discussions. I'm speaking about the geometry of the black hole and nature of spacetime for hypothetical events enclosed by the event horizon.Quote from: Halcsince I don't understand the meaning of a frame of reference of something at a singularityIt appears you are talking about what happens near a theoretical "singularity" my arguments are essentially that this never happens. What prevents it from happening. In the first simple arguments it is just that a stasis can be reached via the energy outflow caused by the increasing gravity gradient at the "surface" (hawking radiation) overcomes the energy created by any further contraction towards the singularity. I tend to equate this with what other writers have called the quantum firewall.
