One of the "made my day" moments in my life was when I had been studying Schwarzchild's GR solution for a spherical non-rotating massive object. He gets a quadratic equation, and its two solutions are almost universally interpreted as being the exterior and interior of a black hole. But I didn't (and don't) think that was right: I thought that (as often happens in physics) only one of the two quadratic solutions applied to the problem at hand, and the other was just a spurious mathematical result with no physical significance. So with my interpretation, there IS nothing beyond the event horizon. I expressed that view on a moderated usenet group ("foundations", which no longer exists), and said that I realized I was in the tiny minority in that view. The moderator told me I was in good company, though ... Dirac had published a paper in 1962 concluding the same thing. The moderator gave me an on-line link to his paper, and I read it, and confirmed that our views were the same. If Dirac ever changed his mind, I'm not aware of it.

That's basically the firewall theory, all the mass is just outside the event horizon.

I've never heard of the firewall theory. All the mass is distributed uniformly on the SURFACE that is the spherical event horizon. And there is NOTHING (including space) INSIDE the spherical event horizon!

I have been trying to find what caused me many years ago to conclude that Dirac shared my belief that there is NOTHING inside the event horizon of a black hole. A contributor on Sciforums, with the ID "C C" just dumped the answer right in my lap. Here is my reply to him:

"C C", your above post COMPLETELY solves my problem! Thank you!
That first page of a paper Dirac wrote ("Particles of Finite Size in the Gravitational Field", published Nov 27, 1962 in volume 270, issue 1342 of the Proceedings of the Royal Society, https://royalsocietypublishing.org/doi/10.1098/rspa.1962.0228) contains EXACTLY what I've been looking for. The critical phrase I've been trying to find again is [which I'm highlighting in red]
"so I feel that the space inside the Schwarzchild radius must belong to a different universe and should not be taken into account in any physical theory."
(The "Schwarzchild radius" is the event horizon.)
