• Question: Einstein said that if you approach the speed of light, time slows down. Once you hit the speed of light, time stops. If that is so, how come light can travel from point A to point B if time is stopped for light? Confused yet?

      Time doesn’t stop – but when you have an observer and a moving object, time plays some funny tricks.. so even if you each think you are travelling away from each other at the speed of light, your observations will tell you that you appear to be moving apart only at the speed of light. Time slows when you are having fun at the speed of light.
