Question: Black holes are an object with such gravitational force, that even light can't escape it. They have enough energy to swallow whole Stars (Including the sun). So what will happen if a black hole tries to suck another black hole? Seeing that Black holes have lots of energy, will it explode and release all the swallowed energy that it has or will they swallow each other with no consequences what so ever?

  I think black holes can be different sizes so I’d guess that the big one would take over the smaller one, and they would merge and become one huge black hole.
