    Love PBS Space time!

    So like in your opinion, tldr, do you think it’s explicitly impossible for light to survive entering a black hole such that it could reproduce an image of whatever it reflected off?

        Light that falls over the edge of the event horizon cannot get out again

        I’m talking as an inside observer. Like what if spaghettification = red shift and the “too large, too old, to developed” galaxies like MoM-z14 detected by JWST are actually from outside our universe’s event horizon.

      From which point of view?

      If the observer is inside the event horizon of the black hole, they’ll see the light as normal. There’s nothing special about the event horizon for the observer or the ray of light.

      If the observer is outside of the black hole, they won’t ever see the light.

          It’s definitely possible in the case of a real black hole. I think it’s unlikely to apply to the model we’re talking about - the spaghettification would have to happen outside the event horizon, and that only applies to very small black holes.
