Why Can Black Hole Binaries Have Dramatically Different Masses? Multiple Generations of Mergers
Black hole mergers with very different masses tell us how small mergers can give rise to even larger ones.
It might just be possible to see a light flash too when black holes merge
Black hole merger events are some of the most energetic, fearsomely energetic events in all the cosmos. When black holes…
