While what exactly goes on within the event horizon of a black hole is still well within the realm of theoretical physics (and it’s said that at the very heart of a black hole physics as we know it gets a serious kick in the pants) researchers are learning more and more about what happens in the immediate vicinity around a black hole, within the flattened disk of superheated material falling inexorably in toward the center. Using supercomputers, scientists can model the behavior of black holes’ accretion disks and see how gas behaves as it gets accelerated and drawn inward, heated to millions and even billions of degrees.
Here, an animation shows the activity around an active, non-rotating stellar-mass black hole. Taking 27 days to complete on a supercomputer at UT Austin, it shows “a turbulent froth orbiting the black hole” at relativistic speeds — that is, very close to the speed of light. Using this data, scientists are able to see how a black hole heats gas and emits different kids of x-rays… it’s the next best thing to being there! (Actually, it’s probably a much better thing than being there.)
