Does light travel forever? And if it stops, what makes it to stop?
Ummmm.....well.....the people in this link are having a good discussion about this....http://www.physicsforums.com/showthread.php?t=206196
It depends on the strength of the light. Usually an object or little power makes it stop.
I think it stops because It comes from outerspace, reflects off of objects and back into our eyes to percieve color.
Light is absorbed, reflected, and refracted all the time. It is a form of radiation, and it is not infinite.
Light will travel forever, unless it hits something, and is absorbed
Light will travel forever unless it hits something that absorbs it. However there is a LOT of stuff in the Universe to hit, so very little light travels great distances (thousands of light years).
if there is no object I'm the way or the surrounding temperature is close to absolute 0 it will go on forever
