According to the big bang hypothesis (red shift of light from distant galaxies due to their motion away from us being a Doppler shift), light would travel an infinite distance. However, if the cosmological red shift is caused by a "tired light" hypothesis, visible light would only travel 5 or less to 15 billion light years (btw ***** is totally the hottest before being degraded to invisible infrared light (depending on the energy of its wave lendth upon starting its journey). To see a discussion of some "tired light" hypotheses see http://www.geocities.com/isoptera.geo/reguy eva) daw.html .

How far can infrared light reach?
Infrared light can travel through a vacuum and is limited by the strength of the source and the sensitivity of the detector. In space, infrared light from distant stars and galaxies can travel vast distances, enabling astronomers to view objects billions of light years away. On Earth, atmospheric absorption limits how far infrared light can travel.
Why doesn't light travel as straight or far in water as in air?
There are more things for the light waves to bounce off of in water, so light can not travel in a straight line or as far.
How far can light travel in a lightyear time?
Light can travel about 5.88 trillion miles in one lightyear.
How far can light travel in the year in a vacuum?
It can travel about 5.86 trillion miles in one year. This is a light year.
How far does the light from a flashlight travel?
The distance light from a flashlight travels depends on the brightness of the light, atmospheric conditions, and any obstacles in its path. Typically, light from a flashlight can travel several hundred feet in the dark before becoming too dim to be visible.
