Hey, so this interest in the galactic rotation anomally I've got. I was reading that, according to GR, black holes kinda wrap space-time around with 'em, yeah? , and really all objects that rotate wrap space time around 'em ( not that much though ). In fact NASA are testing this GR prediction right now with GravityProbe B, by observing 3 spinning gyroscopes which are in orbit around the Earth. Now, is it possible that this wrap around thing could be having a large effect on the galaxy? If the galaxy's wraping space time around with it, then obviosly stars would have a relatively slow orbit velocity. Really it's just a question of magnitute of this wrap around effect. Does anyone know if it could be strong enough?
