how far can light travel from galaxies millions of light years away?

answers:
duke_of_urls say: Light's travel limit from galaxies is a light year larger every year. The limit is the age of the universe in years minus about 400 million years, when the first galaxies formed.

Ronald 7 say: As far as it wants until it lands on something then it becomes a shadow
Only for shadows our Night Sky would be white
-
CarolOklaNola say: Light can travel an infinite distance for for an infinite time, but it can be absorbed, reflected or refracted. Light is an electric field perpendicular to a magnetic field and is both a compound transverse wave and a stream of photons that does not require a transmitting medium.
-
Jeffrey K say: There is no limit on distance if you give the light enough time. We see galaxies 13 billion light years away. We can't see further because light has not had time to reach us since the beginning of the universe.
-
YKhan say: As long as the light sources are bright enough, you can see them forever.
-
Acetek say: all the way. if nothing got in the way of a photon of light it would travel forever
-
Lee say: Millions of light years, you just answered your own question.
-
poldi2 say: We can see galaxies that are 13 billion light years away (not worrying about cosmological expansion or other factors) so that light traveled 13 billion light years.
-
Barry say: Ad Infinitum.
