If I put a log through a wood chipper, I can't un-chip it! Why should we expect the same for stars getting torn apart by intense gravitational fields?
Does it matter that the gravitational field is literally "spacetime itself" changing shape, versus two pieces of matter interacting with each other as in the wood chipper case?
Here's my guess of what's happening based on what you read, please tell me where I'm going wrong:
Physics generally assumes that it can be theoretically un-chipped; if somehow I could run time backwards, that I would end up with exactly the same log that I started with. But the results of interacting with with the mathematical singularity in the black hole cannot be "undone" in this way. And so far, all attempts to avoid trying to model "matter that has passed through a singularity in spacetime" with some kind of firewall, etc. have failed.
