Re: Smash???
During the last few seconds of a black hole merger things happen at close to the speed of light. The spins of the merging black holes flip by a large amount and a lot of gravitational energy is emitted. In one case three sun's worth of energy (E = mc2) were emitted and it was brighter than the whole visible universe. The emitted gravitational waves are directional causing the merged black hole to fly off at a large fraction of the speed of light (~ 1/100 C).
I wouldn't want to be anywhere near such an event.
