What Happens When Two Black Holes Collide?

AI Thread Summary
When two black holes collide, they are first drawn together by their gravitational fields, leading to a spiraling motion before their centers collide. This collision releases a significant amount of energy, although the resulting black hole has less mass than the sum of the original black holes due to energy lost through radiation. The concept of binding energy is relevant, as it indicates the energy needed to separate the merged black hole. Ultimately, the merger results in a larger black hole, but with a mass deficit compared to the initial combined mass. Understanding these dynamics is crucial in astrophysics and the study of gravitational waves.

Its believed generally that when you collide two bodies with enough force, then the bodies group together by the attractive force and grow larger in size and mass..

Based on the similar concept, when two black holes collide, they just don't hit on each other, firstly, they get attracted by each others gravitational fields and they start they start to get close to each other, and hence due to that, they start to revolve around each other and finally their centers collide releasing a huge abount of energy :/ or some things like that I guess xD

Their masses increase etc...

Just to clarify, the two bodies actually have LESS mass after the collision than the sum of the two bodies before the collision due to energy lost through radiation and other means.

Right. This represents the binding energy that would be required to pull them apart after they settle. Though, for black holes, have fun trying to pull apart a merged black hole.
