  1. I don't think it is so much a question of what it is, rather than why it is. What it is, is an attraction of smaller objects towards those with larger mass, hence why the planets don't fly out of the solar system (the mass of the sun), and why black holes have inescapable gravity (huge mass). Why this is as it is would be the question.
