(1) Is the gravitational singularity (or space-time singularity) the same as the black hole singularity?
(2) The wikipedia page says
Physicists are undecided whether the prediction of singularities means that they actually exist (or existed at the start of the Big Bang), or that current knowledge is insufficient to describe what happens at such extreme densities.
Is this really true? As I know, A lot of physicists think there is no real singularity in nature, but are they still unable to make decisions about the existence of actual singularities? I wonder if there is no singularity in nature apart from the completion of physics theory that can measure or predict a certain physical quantity by removing physical infinity.
