Reply to comment by PlaidBastard in Could a black hole just be a big neutron star that just has gravity so high light cant escape? by SlyusHwanus

The singularity is a finite distance from the event horizon which means it's a finite time away (as measured in both time and space and the distinction could matter in this case) when inside the event horizon. You will catch up to something and that something should be a singularity.

The acceleration felt by the atoms or neutrons in a neutron star is > the speed of light. Nothing can resist ending up in the infinitely dense center. There is no physical mechanism we know of that could resist it.

So, really, you're one layer of an infinite relativistic spacetime-baklava of matter approaching the singularity...

I guess. The mathematical models we are using to guess at what is going on already break with what we've got.

Really as someone who intends to never enter an event horizon, mathematically there is no difference between the matter of a black hole being in a singularity, or being evenly spread just under the event horizon. The stuff that comes out of a black hole, gravity and charge, don't care so in a very real sense there isn't a difference.

In fact it might not even be defined in the same sense that many things in quantum mechanics aren't defined until measured. And since it can't be measured as far as the external universe is concerned, why would reality care to pick?
