The idea of a singularity is a problem for Big Bang cosmology and the singularity general relativity says existed at the start of the universe needs to be removed.There are singularities predicted for black holes too. Isn't the most likely explanation, to stop a singularity from forming, that gravity gets weaker for some reason when mass gets beyond a certain density? Since current theory cannot explain such a scenario, we would expect the correct theory of quantum gravity to show that gravity does in fact get weaker above a certain mass density, and that the underlying reason is a gravitational coupling constant that has become weaker? Could gravity show asymptotic freedom of some kind for masses separated by short distances? What are your thoughts on this?
