> Isn't all of this explained by the fact that we have a supermassive black hole at the middle of the galaxy? > We perceive distant time to run slow because we're falling into a black hole. We’re not falling into it The mass of Sagittarius A* is 4.1 million solar masses while the mass of the galaxy is 1.5 trillion solar masses. Our orbital velocity easily exceeds the necessary velocity to orbit Sagittarius A* at our current distance. You feel more gravity from a paperclip a meter away than you do from Sag A*
