I can see a bit of quandary here. Well, how this point would appear from the
AWT perspective?
Every gradually collapsing object will reach the moment, where it's surface density gradient (expressed by its surface energy gradient) will exceed its inner mass/energy density at the center. Simply because the gravitational field inside of every massive object is flat (believe it or not, inside of Earth is weightlessness), while the gravitational force/curvature of space-time (and the energy density by Einstein's field equations as well) remains highest somewhere near the surface:
Can you see, guys, the problem? While the classical Schwarzschild's solution of black hole is quite relevant from formal point of view, it's just
steady state solution, which is assuming , the highest curvature of space-time is exactly at the center of massive object from it's very beginning. This is the situation, which
can never occur spontaneously inside of real massive object, indeed. The another derived problem is, the convergence of steady-state models can - but necesarilly doesn't have to - follow the time evolution of corresponding time-dependent model. By such view, even the carefull solution of steady-state models by iterative way can miss the physicall y relevant solution completelly. And this is the thing, which is sometimes quite difficult to explain to formal theorists - and I am pretty sure, nobody of relativity theorists hasn't considered it till now.
Therefore, if we want to see, how the REAL Schwarzschild's BH solution CAN appear, we should always follow the time evolution of time-dependent model, not just the steady-state approximation of it. The above difference simply means, at certain moment of gravitational collapse, the energy density of black hole will exceed the internal energy density of collapsar, thus violating the elementary buyoance condition. The surface of such massive object will start to undulate in looking/waiting for possibility, how to collapse further. And whole the object will change into udulating quantum wave (see the animation on the above).
While the undulations of large black holes can be quite dynamic, we should realize, near/inside of black hole the energy spreading speed is quite minute, so that from internal observer perspective these undulations will appear as a quite slow process, followed by many gradualistic phase transform. Briefly speaking, from internal observer perspective the wildly undulating Universe/black hole can appear as a quite calm and "classical-only" object.
I hope, now you all can understand better, how the AWT is working and how it can contribute to the quantum gravity theory.
