What happens when 2 blackholes collide?
Do blackholes follow orbital paths?

>>	Anonymous Fri Dec 31 22:32:14 2010 No.2278460 >>2278456 Yes they follow orbital paths if that path is strong enough. If they collide, they'd just merge and form a new center. We'd probably just 'see' the event horizon messup a bit and grow larger.

>Do blackholes follow orbital paths?

Yes.

I think a black hole colission would be unlikely, those two objects accelerating into one another would result in quite a bit of orbital velocity: For both. So they'd most likely fly real close to each other, and end on two near-hyperbolic orbits, like really thin ellipses interlocked in a single point where they touch.

Or if they actually do collide, then you'd get both event horizons mixing together and what have you, but I dunno what would happen to the Singularity.

They can and do collide. A pair of them orbiting each other constantly lose orbital kinetic energy through gravitational radiation. As they lose energy, they move closer together and orbit faster. (This has actually been observed).

Eventually, they collide and merge into a larger black hole. This collision theoretically emits a pulse of gravitational radiation large enough to be detectable by some proposed gravity wave detectors.

>>	Anonymous Sat Jan 1 03:24:14 2011 No.2279586 This is how people think supermassive black holes are formed... Admittedly it takes more than one collision with more than 1 black hole.
