Set v = c to obtain Schwarzchild radius. https://en.wikipedia.org/wiki/Schwarzschild_radius …

It’s a misleading coincidence that the Schwarzchild radius is where the classical escape velocity equals c, and this is often misexplained when introducing the concept of black holes

well for one there's no reason newton's laws should be able to say anything about strong gravitational fields and be correct

that's what we mean by coincidence .. you can't expect that what you plug into Newton's laws will agree with GR

but you're considering relativity! it *is* a coincidence that Newton's laws just happen to agree on the schwartzchild raidus when it has no right to .. what we're saying is you can't blindly continue this logic and expect to get correct results

you're not hearing what i'm saying bruv.. The point is that blindly applying newton's laws is like applying the theory of quarks below the confinement scale. Do some things work? Yes. Do all of them? No. We got lucky that the correct things survived the strongly coupled limit
