Hi everyone. Does anyone know what would happen if two black holes got too close toghether? Would the merge and become a supermassive black hole?
nicksauce said:They would merge and form a black hole with mass roughly equal to the sum of the masses of the original black holes.
marcus said:You may have seen research papers based on computer simulations of such mergers:
BH+BH, or BH+Neutron Star,...
The two compact objects, while spiraling in close and then mutually swallowing each other, cause a fair amount of gravitational wave ripple. The idea of the research is to figure out what wave patterns to look for with gravitational wave detectors. Address questions like: Are the detectors being built going to be sensitive enough to "see" events like the merger of two compact objects?
It might be interesting to see some of the graphic output. I remember some from a few years back, but don't have any links handy.

There are a few pictures/movies here, for example, http://www.cita.utoronto.ca/~pfeiffer/
Good point. Conventional theory suggests an outside observer sees an infalling observer 'freeze' at the event horizon. Black hole event horizons could, however, merge in time as measured by an outside observer.Matterwave said:I've wondered, doesn't time "stop" (from an outside observer's point of view) at the event horizon of a BH? So how could anything fall into a BH or merge with one?

Chronos said:Objects approaching the event horizon of a black hole suffer from extreme time dilation and redshift from the perspective of a stationary external observer. Fortunately, a portion of all matter falling into a black hole is merely ripped to shreds and jetted back into space.
Black holes are regions in space with such strong gravitational pull that nothing, including light, can escape from it. They are formed when a massive star dies and collapses in on itself.
When two black holes get too close, they start to orbit around each other. As they continue to get closer, they eventually merge into one larger black hole.
No, black holes can only merge with other black holes or objects that have already been consumed by a black hole.
The merging of two black holes would create intense gravitational waves, which would ripple through the surrounding space. This could cause disruptions in the orbits of nearby planets and stars.
No, the merging of two black holes always has an impact on the surrounding space due to the release of gravitational waves. However, the impact may not be significant depending on the distance of the black holes from other objects.
