If an object is traveling at the speed of light, gives off light in all directions, does the light given off towards the opposite direction of the object "stay there"?

The object would be traveling at 0.999..... of the speed of light

Light emitted from an object leaves that object at a given point in space as though the object were stationary so it propagates from that point (in other words RELATIVE to that object). We would detect the light shifted towards the red because of the Doppler effect if the object is moving away from us and blue shifted if the object is moving toward us. That's how the expansion of the universe was detected

By "opposite" direction, do you mean that the object is moving to the right, and the light is given off to the left?

No, it does not stay there. It moves at light speed. The speed of light has nothing to do with the speed of the object that emits it.

The Sun or stars are moving mass structure giving off light in all directions. Some of the light travels up to the edge of the Universe and stays trapped revloving around the Universe boundaries. So the Universe is the Black hole that does not let light escape.
Note; Einstein"s first postulate of Relativity, indicates that the speed of light is constant reguarless of the Speed of the Star Source.

An object cannot travel at the speed of light.

But regardless of the emitter's speed, light given off will travel at c, the speed of light. Always. As measured by anybody. No one will ever observe the light to "stay there."

I think I get what you are asking even if it is impossible. I'll try to put it in words

If the object is traveling lets say 0* (degrees) at .999 the speed of light and the ligth given off at 180* is stationary because it has to travel faster then the object the produced it. So basicly the light has to catch up to the speed it was created at and being they are equal it doesn't move....
I think thats what your saying.

If the object isnt going at 1.00 then the light will not be stationary because it is moving ~.001 faster.

But like they said its impossible.

Can't happen. If you believe Einstein's theory that E=MC^2, then an object approaching the speed of light would be of almost infinite mass. An object can not reach that speed. But if it could, it would give off a heck of a lot of light as energy.
