Believe it or not, it's even been measured. We put an atomic clock on a rocket and made it travel fast and when it came back to Earth it had lost time.
As for the 'why', there's probably only a handful of people on the planet who could explain that - 'because Einstein said so' works for me
There are lots of thought experiments to help you get your head around it, involving light beams and moving trains and the like. I've tried googling for an easy link but there's always going to be a certain amount of pain involved in thinking about it [img]smile.gif[/img]
