Since it has to do with time, I actually read this spam:

I recently had an argument about why time is relative. My friend found it hard to conceive how time could not be absolute. At that time, when I tried to explain it, I found that it was hard for me see WHY time really is relative. All I could do was state experimental results that indicate it is the case. This shows that thinking you can understand a deep concept at a very shallow, philosophical level doesn't really mean much, but at least it's better than no understanding at all. binge
Newton's laws put an end to the idea of absolute motion. Two people playing ping pong on a moving train would measure the distance the ball bounces on the table (between consequecutive bounce) as lesser than a person standing along the track watching the ball bounce. Both measurements are equally valid since there is no absolute standard of rest. lubricity
Maxwell's equations predicted that light waves travel at a fixed speed. This is something we have to believe, and it arises out of the fact that his equations predicted "there would be wavelike disturbances in the combined electromagnetic field, and that these would travel at a fixed speed, like ripples on a pond." spook
