 One light-year is the distance that light travels in one year. Recall that the the number of seconds in one year is 𝜋 x 107 seconds, and the velocity of light is 3 x 108 m/s. If we could see a star that was 10 billion light-years in distance away, how far in meters did the photon travel?Expired on
