Not as far as we know. Light, unless it is absorbed by some gas or dust, does not seem to be attenuated at all in vacuum. We can certainly see the light of galaxies that are close to the age of the universe. In linear distance that translates to over 10 billion light years.

Photons are what light is made from. As far as science is concerned, photons have no mass. Therefore, they are not affected by gravity in any way. The only thing that can stop a photon beam (a light source) is something that can block it. This includes, but is not limited to, asteroids, planets, stars, comets, dust, brighter objects near it that would hide the light from your sight, and probably a black hole.

Amansscientiae gave an excellent answer. Light never speeds up and never slows down. It changes direction and it can be absorbed, but in open space it never stops.

If Jesus ascended bodily into heaven and achieved the maximum speed for a physical object 99.99999% of light speed he would only have reached the outer limits of the milky way galaxy after 2000 years. He would still have a long way to go before getting outside the universe !

William be is wrong in every sense. Light can be bent by magnetic fields and gravity. Where did you gain you Bsc ?

yeah. light, in theory, will never stop unless its course is altered by some particle of matter.

No. Not unless it hits something that absorbs it.
