I introverted think. Therefore, I am.
I just though of this, and it's bothering me. Two super massive black holes were just discovered orbiting each other. This is something I've wondered before, but I still don't have an explanation. How can they move?
Beyond the event horizon, time dilation is so extreme that time has stopped. By my understanding, that means nothing is in motion by our temporal perspective. So you'd think that the accretion discs would orbit around a fixed point at the centre. But that isn't the case. The whole structure moves uniformly around another structure it is orbiting, or in this case in a mutual orbit. Galaxies with super massive black holes move around larger groups, and smaller stellar black holes move around the centre of the galaxy.
Everything outside the event horizon should be in motion, but at this centre, if it were truly frozen in time (or at least the dilation so extreme as to be frozen to all intents and purposes from our perspective). So how can the whole structure move? How can the core be in motion if it is frozen in time?
(Yes, it is thoughts like this that keep me awake at night).
