I'm new to studying this type of physics. I've been watching videos and reading about quantum physics and relativity. This channel has great videos about quantum physics and relativity. But can someone explain the first minute or so of this video to me? (apparantley I can't post links to this site because I don't have ten posts so remove the spaces before and after each dot) www . youtube . com/watch?v=z6pzEh6pE3A&feature=plcp If light is traveling at the speed of light then shouldn't it not experience time? So why then do people say it takes 5 minutes for light from the sun to reach earth? Currently I think it is because light travels both through space and time and therefore experiences both. Just watch the video and you'll understand what I'm asking. Thank you!
