Two Black Holes: Reactions and Behavior

[KnowPhysics]

What will happen if two black holes are coming nearby? what will be the reaction (change in behavior)?

The major effect will that of gravity. They may collide and merge. The may lock into some sort of orbit around each other. They may just pass with some change in direction.

 

[Chalnoth]

If they pass near one another slowly enough, then they will enter into a mutual orbit that gradually decays through gravitational radiation, eventually merging into one, larger black hole. The probability of them colliding straight away is so small as to be negligible.

I don't think it's possible for a stable orbit to occur. The orbit will always decay due to gravitational radiation, leading to a merger.

ok. even i thought same both will merge and create more powerful black hole(High gravity) because of higher mass. here arise another question when it will explode? any specific condition?

Black holes can't explode.

At the center of most (if not all) galaxies are block holes with masses many millions time that of the sun.
