comment Does any particle ever reach any singularity inside the black hole?
you first have to cut out the interior that isn't visible to the outsider, and then glue the rims together, like in a skin operation. On top of that, particles exchange the data about their positions with the data on their momenta. It's all pretty weird, but emerges from my calculations. G. 't H

comment Does any particle ever reach any singularity inside the black hole?
but this becomes physically important only at extremely tiny distance scales (tiny, even, compared to any of the particles studies at the LHC). In QM, the state we call "vacuum" has to be defined carefully, and according to QM, therefore, different observers call different states to be their "vacuum state". That's pretty serious: matter causes gravitational fields. Is there matter or not, at a given point x ? If you can read technical stuff, I advise you to read arXiv:1601.03447[gr-qc]. It tells you that, if you want to know the quantum states of a black hole, ...

comment Does any particle ever reach any singularity inside the black hole?
There have been numerous observations that indicate very strongly that yes, the theory works up to minute detail, and furthermore, if there existed even a slight departure from the theory, the consequences would be huge and highly incredible (observers would be able to distinguish their coordinate fram from that of others, seeing lots of things that have never been possible.) I am conservative, I don't believe in any departure from general relativity, period. But third, there is something else, and that's quantum mechanics (QM). QM forces us to think differently about space and time, ...

comment Does any particle ever reach any singularity inside the black hole?
There are 3 types of questions here. First, on what general relativity says about the geometry of space and time. The theory is extremely clear and unambiguous. We can answer all questions concerning the perception of space, time, and singularities by all sorts of observers. You get the answers by looking at the equations and their solutions. The only reason why I don't answer such questions is that I have no time for that, and anyway, you can figure it out yourself if your math understanding is above a certain minimum. Second, the question whether the theory is right at various points.

The new version v3 of my paper quant-ph/ 1405.1548 was sent to the ArXiv today, Dec 21, 2015. "The Cellular Automaton Interpretation of Quantum Mechanics”. Criticism is always welcome, even if it comes from amateurs, although I cannot guarantee response.

comment Does any particle ever reach any singularity inside the black hole?
... what is needed is a fresh look at scale transformation symmetry and conformal symmetry. A way out could be that such symmetry transformations transform the singular situation with an eternally shrinking observer into a regular description of physical events. That would remove the contradiction, but the technical details are not understood - at least not by me. Questions we can answer are ones about the mathematical nature of any given space-time, like some solution to Einstein's equations, but as soon as new physical principles are asked for, we have to be very careful about what to say

comment Does any particle ever reach any singularity inside the black hole?
@Nathaniel, As for the formal nature of the question, you have to realise that the outside world sees the ingoing spaceship (or whatever) approach the horizon exponentially, that is, every microsecond or so, his distance from the horizon is reduced by a factor 1/2. Imagine what that is after millions of years when the black hole decays. But apart from that, you are right and the question is important. Today's understanding of physics at the ultrashort distance scale is quite incomplete, no matter what string theorists and AdS/CFT considerations try to tell you. I strongly suspect that ...
