If you have two black holes seperated by more than one Schwarzschild radii, given a location at: The event horizon of one of the black holes. A location between both black holes A location on the axis that passes the centers of both black holes. Wouldn't the potential there actually be less than it would be if the objects were isolated? First, note the black holes are pulling in opposite directions, so this isn't simply the sum of the gravitational potentials (is it?), but rather a sum of their vectors! If two black holes were about to collide, couldn't the matter that is between them race out between black holes A and B? Surely the velocity the particle will encounter will only increase. With respect to our frame of reference (and time perspective), is it possible that the matter (which appears to be forever collapsing to the Schwarzschild radius) appear to us as being sucked out as the black holes approach each other? Could the jet coming out of a black "hole" actually be the stream of particles exiting the region near the axis of rotation of two black holes? Remember that from our time perspective (our time coordinate), the matter falling in never seems to cross the Schwarzschild radius, so in a finite amount of time, the matter may be expected to be jutted out in jets (because the black holes would be orbiting each other and the vectors between them cancel). If the masses were unequal, would this stream (between the unequal masses) actually be jutted outside the axis of rotation, causing the jet to be a helix in shape? If the particles were charged a certain way, then helix could expand and become very wide. Because of their relativistic velocity, the expansion would be mostly horizontal rather than vertical. Perhaps I am wrong when I say the vectors cancel each other. If they don't cancel, then what do they do?
