    I was studying black holes recently and I read that when on the near side of a black hole. You, if stuck in the geodesic of a black hole will be red shifted and will fade. The gravity causes spacetime to slow the passage of time to you for everyone outside of the black hole.

    So I was wondering, if time is relative and local for all obsevors, the outsiders see no movement throughout all time, so what would those stuck at the edge of a black hole see the outsiders passing through time do you think? Eternity pass? Or just until the black holes evaporates? What do you think?

    I may be wrong of course but I thought that time slows down for an observer near a black hole; conversely such an observer, looking out, would see events pass quickly (much like the time portal shown in an old star trek program where Kirk and Spock go back in time and Spock has to make a vacuum tube based device out of "stone knives and bear skins" )

    Providing the observer could survive the placement, then looking out from the event horizon would cause eternity to pass in the blink of an eye

    I doubt you'll see anything. If I understand correctly, light only barely escapes, but just can't quite make it.

    If that's wrong however I suspect that you would appear to see from the edge of the event horizon even if you're in the middle? Or everything remains the same?

    I know that light still goes into a black hole and time remains relative to both observors (i.e, the own reference frame time passes at 1sec/1sec). So if no time passes to an outside observor to those on the edge of that black hole, if that has to remain relative, for everything to be conserved, then those in the black hole would have to see everything out vanish? Because eternity passes? I don't know.

    I don't know what it would look like, but I'm sure it would be a little complicated. I'd love to make a topology of the spacetime around a black hole .

    As I understand it, there is, zero proof of black holes existing. As far as I know scientifically they belong in the pseudo science section.

    In other words if you keep nailing down "scientists" about them. The "scientists" suddenly revert to the fact that they are still just a theory.
