What about...not A, not B, but C. C measures the speed. C measures...everything. I'm C see? do you C? i can C ..furthermore, i don't understand how anyone thinks they can sync two clocks if Time Dialation will always UN-sync...a clock? Even if I put my watch 5 minutes ahead... i'm still going to be late! -- The Starmaker -- To question the unquestionable, ask the unaskable, to think the unthinkable, mention the unmentionable, say the unsayable, and challenge the unchallengeable.
