the event horizon

here is an interesting thought. It may or may not be spiritual/philosophical, mayb emore quantum phyisca but then again coul dbe all of teh above.
hawkings described a situation called the event horizon. During shroom experiences i have noted the complete loss of the sense of time. Physicist believe that space/time/light are somehow interrelated.
if one accepts that a "black hole" is a star that has collapsed and is so dense that its gravitational pull is so great, that light can not be seen since within a ceratin distance of this dense huge gravitational pull, light can not escape.
take for discussion sake the possibility that you are an astronaut and are sufficently far from a black hole to see light on either side of it.
At some distance away from the black hole light is neither pulled into the black hole nor is it traveling away. I.e, the EVENT Horizon.
This 'edge" at which point light would begin to be visible, i.e, something seen there, the light that is neither being pulled in or traveling away would represent an image that was there from the time at which the star involuted and became a black hole. lets say that an image on teh event horizon was visible, choose what you wish. that image that you are seing does not change , it lacks the concept of time associated with that space.
thoughts comments?

theoretically the light would still be there but the actual images are a wash of light. There isn't like some big movie screen that aqllows you to see the actual event at the time of collapse. As far as the photons of the light at that time though, I believe they would still be present.

but wouldnt it be a still image, that doesnt change?

there really is no way to prove it because to see it you need to get to the event horizon....you know what happens once you're there.

The edge you describe is infinitely small, so there are no photons that stay on the edge, they either fall into a hole or get out.

actually, no. there is a region called the "Photon Sphere", where the gravitational pull is not strong enough to pull the light, but not weak enough to let it escape. the photons that are trapped there, simply orbit the black hole.

and there is no still image. you need a constant flow of photons towards an observer to have an "image". there is just light there, photons orbiting the black hole (the light is not observable outside the photon-sphere).

correct me if im wrong but arent moving photons or waves, "light" and if these photons were orbiting the photon spere, would they be the light of the image that occured at the time the black hole was created. check out Stephen Hawking's book, he explains this much better than I

As i said earlier it would be a wash of light. It would be the photons that were there during the time of collapse but in no particular organization. Then you have to consider what your point of reference is. If the photons that were going in your direction were consumed by the beast then you will receive no light and hence no image. When an event occurs photons are moving in an azimuthal pattern until an obstacle or force prevents their movements i.e. why you can't see an event through a wall.
