Does the change in gravity gradient across your body kill you right now? No? You are currently orbiting the supermassive black hole in the center of the milky way.
It was implied by “accretion disc” and by the fact that we’re talking about gravitational gradients at all that we’re talking about a close orbit. Gravitational strength gets smaller with distance according to the inverse square law, so by the time you’re a few light years out from the galactic core the gravitational gradient is already extremely insignificant.
