Based on the Schwarzschild black hole theory, if the gravitational pull of the singularity were to equalize the energy that a photon has by approaching the event horizon from a special angle, would it orbit forever (Right next to the horizon) because of them having the same potential?, if true, could this be considered an absolute zero "wall"?
In the case of this being possible, if we were to see those orbiting photons, there's a chance to see images of the past?
Here's what i mean (Please forgive me for using Paint)
I'm relatively new to physics and i'm still trying to understand some things. I find it very passionating when questions like this comes to mind, so if you could help me with more certain facts about this topic it would be amazing!
