- ars 11y agoYou can't see the edge of the event horizon either - time is stopped at such a place. And slightly farther away events happen so slowly they are invisible at human time scales. Even far from a black hole it would be almost impossible see anything. All the light would be red shifted to invisibility (because of the intense gravitational field), and the brightness would be very low because it's happening so slowly. I suspect that some of the very red, very dim, galaxies that are assumed to be very distant because they are hubble-red-shifted so much, are actually super-massive objects.
