Today I read in Science News of evidence that a supermassive black hole has been ejected from a galaxy at a velocity of 2,500 km/sec., possibly by an even more supermassive black hole in a merger of galaxies. This apparently had been possibility predicted by Einstein's Theory of General Relativity. What I know about general relativity is that it is stated as a set of partial differential equations that are WAY beyond my mathematical ability, which had trouble with plain old differential equations. I also know from reading that solutions are often found at limits or boundary conditions where some elements drop out, simplifying the equation.
Non-the-less 20 yrs ago when I was considering attempting a SF story I postulated a "black hole drive" consisting of two microscopic, confined black holes which were manipulated in such a way as to cause gravitrons to radiate in one direction and anti-gravitrons in the other, thus producing acceleration. Alas, how to do this never came to me, so I am still here This idea certainly did not fall out of any deductive process, but was entirely based on intuition, perhaps the greatly delayed result of psychedelic consumption in the late 60s-early 70s. So I was taken by the observation that black holes could repel each other and produce acceleration. Thus your clip really sent me on a non-psychedelic trip.
