$\begingroup$ Nice answer, but you might like to update it a little, now that LIGO has observed a BH merger. I'm a little puzzled what "Kinetic energy cannot exceed the speed of light" is supposed to mean. Relativity limits speed, but not KE. OTOH, KE will be consumed as an energy input to the BH merger, although some energy & momentum will be emitted as gravitational waves. BTW, check out the BH merger sim video I linked here. $\endgroup$
