Oh there are black holes. We even have videos [1]. But are they infinitely dense at the singularity or is there a limit? [1] - https://www.eso.org/public/vide

- t8sr 4y agoI mean, look - arguing about what happens inside the even horizon is kind of fun but ultimately pointless. Just FYI, the site you linked in the parent comment does not represent anything I’d call mainstream physics.

- t8sr 4y agoNot really, that’s just the same guy writing a PDF. It’s not cited, peer reviewed or published in a journal. It’s literally just a dude writing stuff on the internet - that’s not necessarily a problem, but there are literally tens of thousands of people with “great ideas” that marry GR and QM, and none of their theories go anywhere, or make any testable predictions. He makes some bold claims, no predictions and doesn’t seem to get published, which strongly indicates he can’t get past peer review.
- snarfy 4y agoThanks for this and for shooting it down. There is enough wild stuff on the internet that it doesn't need to be perpetuated further. I read this maybe a couple years ago and it seemed legit, but I'm not a physics guy and didn't really research it more or notice it's just one guy. The idea of a maximum force is interesting in that it would put limits on some theories.
- philipov 4y agoOur theories break down at the singularity and we don't know what happens there. That's part of why quantum gravity is such a big topic of research.
- SAI_Peregrinus 4y agoAFAIK, most mainstream physicists assume the singularities are an artifact of the incompleteness of General Relativity, and that they won't exist in a theory of Quantum Gravity. Singularities and infinities in physics tend to indicate problems with a theory, they're the reason it's common to say that physics "breaks down" inside black holes.
