First off I couldn't decide whether to enter my question in the relativity section or this one, so if I'm in the wrong place my apologies. Anyway I have a question or perhaps a hole in my understanding. I was wondering if there is a density point at which anything becomes a black hole. Now I understand the conventional black hole where the mass of a neutron star becomes so great that the gravity will crush it into a singularity but I'm wondering if hypothetically we crushed something down to the point where it would be the size of the singularity would a black hole form? Of course it would be an everyday object nothing close to the mass of a star, so could it still form a black hole? Sorry if what I'm explaining comes across a little vague or disjointed but I'm having a bit of trouble describing what I'm thinking of.
