How far does light travel in space?

Question

How far does light travel in space?

Answer 1

until it it hits something that absorbs it and converts it into heat

Answer 2

it keeps going until something stops it.

Answer 3

Light is both like a wave and like a particle. Particles don't need anything

through which to travel; in fact, you might expect particles to travel better

when there's nothing for them to interact with. Light is like that, too.

Light travels faster in a vacuum than through any material.  

Answer 4

Photons are immortal.  When most everything else in the Universe has decayed, there will still be photons from the Big Bang zipping on their way.  The expansion of the Universe will cause them to red shift to very long wavelengths, but they'll still be out there.

Answer 5

Infinite distance. It just keeps going, and going, and going, until it's absorbed by something it hits.

Answer 6

i think the edge of the solar system is about 7 -9 billion miles

so i guess this is where the suns rays might start fading away

then again i could be completely wrong but i'm sure you can make out the sun when at Pluto / Uranus 3 billion miles

Voyager probes have just got to the edge of the solar system after 30-40 years space time apart from one went north one went south & solar sytem ends 1 billion miles shorter than at one of the ends

Answer 7

in either an open or closed cosmic system, light will travel an infinite distance

Answer 8

Actually we cant explain that but its limit less

Answer 9

there is no limit
