LogicaLunatic - I absolutely *love* your signature! Fantastic!!

I like your thinking on the light/time thing. Very original. I think I gathered that you were implying it just as a 'model', i.e. a way of thinking about it but not the way it actually is? Or did I just imagine that?!

I think the nature of time is one of the greatest mysteries, but also one of the most important things to understanding the way the universe works. If you can crack time, everything else should just come easily.

If Einstein had lived longer, do you think he would have cracked it by now?

How about this model: space is multi-directional, in that you can go any which way you please. What if time, as just another dimension like the other three, was multi-directional too? That would mean that when time appears to slow down for you it could be because you are going 'diagonally' in time, relative to a stationary person going in a straight line. Then either person could view themselves as going at the correct rate through time, and either could/would see the other as going slower relative to them. The true measure of time, then, would be in-between them... I think?

I think the hardest thing is getting an idea from your own head in to somebody else's without having it missunderstood or without sending the other person into a deep hypnotic trance!!

Another thing I struggle to get my head around is the whole light-speed thing. I just don't like it at all! I refuse, for example, to believe that light has no mass. If it did it would not be limited on speed and it would not be slowed down upon 'contact' (how can something with no mass come into contact with anything else?) with water or glass.

But that's another argument! This is why I love physics... it's like the ultimate mystery, the solution to which is always just one step away, or so it seems.
