I was just reading on inflation and the book was saying that since the universe is expanding, the light we see from stars are now ALOT farther away from us now. This seems to my noob mind to be contradictory to relativity. If you on a train going 500mph at a beam of light the beam of light is only coming at you at the speed of light. Not the sum of the speeds. First question. Why is this the case? Seems impossible. lol Second question. Does the universe expanding faster than the speed of light throw any wrenches in current theory? Do the two statements correlate with eachother at all? The distance that light travels is the distance it was from us + the inflation distance of the universe . & The speed of light is constant for everyone regardless of velocity.
