Fantastic, thanks for elevating this thread to a nice qualitative discussion. Color and bold by me. (pl expand the quote above) I agree with your uncolored part in entirety. The Paddoboy's photon hovering link (quite famous once upon a time here on SF) is fine but photon comes inside as soon as even a single additional photon is accreted by BH. But I disagree with the color portion. consider the qualitatively most simple density distribution, uniform density spherical symmetry object just inside its Schwarzschild radius. I have given an example say of 1 million solar mass. Except the outer most surface, every other inner part is outside its Schwarzschild radius (Uniform density just at its EH, apply mass / volume formula to get the radius of inner 0.1 - 99.99% mass (any fraction), you will see that fractional sphere is out of its Schwarzschild radius. Now freely apply Newtonian or Birkhoff's (in relativity) and you will see that a photon emitted just inside has no bar in moving away from center. (of course it will remain trapped inside outer EH), and of course I am just going with you, it may be swayed down with the collapsing mass. But it does not end here, the object keeps collapsing from 3 million km. And as per my assumptions a stage comes, R(p) = 640 Km, (640 to 3 million is empty and 0 to 640 is densely packed Neutrons, a sphere of uniform density, say), here too as I have shown even when one million solar mass is compressed to 640 Km, the innermost 3.24 Solar Mass is still outside its schwarzschild radius, suggesting that a photon produced anywhere between 0-10 kms (3.24 solar Mass will be within 10 km), has no bar (Birkhoff's or Newtonian) to travel away from r = 0. Now You may say that I am questioning the veracity of Kruskal diagram, may be yes, may be no, because this diagram is not talking about any photon produced inside, this diagram is either about the collapse once the object falls below EH or of any incoming particle. I am talking about photons produced at r = 0, while the object is collapsing. Thats why I am also seeking some one else intervention, like you are also seeking.
