If time stops at the speed of light, how does light travel throught space and time? Example: The light from a star 12 light years away travels throught space and takes 12 years to get to earth. But in those 12 years the time on the star has stoped. Same goes for the light that is leaving earth and traveling to that star. No time is exchanged. Isnt the fact that light itself traveling at the speed of light mean there is no time at all, and that all things we see are now?
