Is There a Singularity at the Centre of a Black Hole?

We don't have a theory of quantum gravity, so we just really don't know what's going on inside the black hole. The gravitational force is so strong that everything will just end up being squished into singularity. So that's definitely a problem that life inside black holes would have to overcome. I bet it's that baseball i threw out of my yard and my parents had got stuck in the neighbors yard. But i'm pretty sure tospake that and all the unpaired socks i have. That one is definitely in a black hole somewhere exactly yes.
