I just noticed something interesting. For a certain amount of mass, if you compress it enough it will form a black hole with radius R=2MG/c^2, where M is the mass, G is the gravitational constant, and c is the speed of light. For the sun this radius is about 1.5 kilometers. For all the mass in the visible universe, the black hole radius is (drumroll), the current radius of the universe. More on this latter...
