Black Holes

Why did it take so long for black holes to become accepted as fact? It is a simple function of mass/volume to gravity?!?
Take the mass of a large star, or billions of stars, compress that mass to the size of an atom, and you have an object with enough gravity to capture light.

I am looking forward to research on how dark matter and dark energy affect and influence black holes. What is the interaction?

Thats all I have to say about that. - F. Gump
