   There are singularities that are just "coordinate singularities".

    As far as I know, people say the Big Bang is also a real singularity,

Leonard Abrams published a relevant paper on this topic in a Canadian physics journal somewhere between 20-30 years ago as well as delivering lectures on the topic at Cal Tech. He, essentially, showed that the Schwarzschild derivation was mathematically flawed. Essentially S translated the coordinate system and made claims about the analytic continuation of the system. Abrams simply showed that there was no analytic continuation! This doesn't say there are no black holes, but Schwarzschild's mathematics isn't a proof. The acceptance of the paper was cool but no one has properly resurrected the result to my knowledge.
