RE: ASK ME PHYSICS: I know time slows down when you move faster (barely noticeable unless you approach the speed of light). But why?

Yes thats the most common theory of light, however it is possible it travels slightly under the the universal speed limit, which if that was the case all hell would break loose and all our theories would go tits up. but it is extremely hard to measure the universal speed limit if you dont consider light.
