Well, yes. I know there is a lot of static, but I was reffering to the stuff that matters. Too many staellites. ;-)

Hello guys


Please help me understand.

If gravity reacts at the speed of light. Why is light its self effected by gravity. IE light cannot excape a black hole.


It seems to me that gravity gone wild ( blackhole ) the effects of gravity in a black hole reacts much faster than light.

http://en.wikipedia.org/wiki/Photon light photons everything.

Technically speaking a photon=light photons have no mass. If you understand that gravity is always present then its not so hard to understand. You also have to understand that a blackhole causes massive gravitation pull. More than we could ever get in a lifetime from our own sun. Because of the massive gravity even the photon cannot escape from the blackhole. There is eveidence that gamma radiation is emitted from blackholes.

heres an interesting thought though. We know blackholes prevent light from escaping. So what about a star. A star emits light would a stars mass slow a photon down? is their a gradient for light emission/gravity wells?

Space_time is really complex, but here is a simplification.

If the hole has been there a while then the gravity has too. So that photon you shoot out feels all that gravity and can't escape.

If the hole hasn't quite formed yet that photon doesn't feel enough gravity to stop and it escapes.

I think you get the above two.

At the instant the hole forms gravity goes out at the speed of light just like the photon. It is a race of the event horizon and the photon. Depends on the exact starting position as to who wins. Like any door shutting there is always a last thing that gets out.

so at the event horizon wouldnt we see a narrow band of photons that are "frozen" in place if we had the facilities to detect them.

That may be, for the special relativity theory, but, will that be sufficient for modern string theory. Known as 'exotic particles' travelling in and out of different dimensions that will be dictating different gravity laws, which will the photons [perhaps gluons] merge with.

There is no "gravity"; space itself is warped into a convoluted singularity that is turned in on itself. light follows geodesics which in this case are hopelessly wound into an infinitesimally small knot.
