This question has been on my mind for quite some time.
I don't really have in-depth knowledge about singularities, but from what I understand they rupture the spacetime and they are hard/impossible to describe in a scientific way, because you are dealing with infiniteley dense objects in an infinitely small point. Somehow it seems reasonable to me to assume, they don't exist to avoid all this trouble.
As I understand it, one way that a singularity forms is by a massive star collapsing to a single point under its own gravity. But that's just how the collapsing star experiences it, right? For the outside world, this never happens because time slows down more and more as seen from the outside.
So the singularity is never finished and hence does not exist. All we see, are objects that are endlessly becoming singularities, so the math is still finite. No more headaches.
What are your thoughts on that?
