Why are black holes so dense?

They are so dense because they have a giant star (roughly 50X the mass of our sun) compressed so far that light can't even escape. To put this in perspective, think of how big our sun is, then, Scale it up to a size in which 500 suns can fit into it, now compress that to the size , roughly, of the moon. That's why.
