"We move through spacetime at the speed of light"
OK. Let's tackle this one first. OK. The only equation I knew that connects speed and time is from that same freshman lecture about Special Relativity. I stared at this. Turned my head sideways, first to the left, then to the right. Upside down. With some algebra, I saw it. It's the equation of a circle! SIDENOTE: I've wrestled mightily on this. With c as the max, v/c always has to be less than one. So Δ t 0 has to be less than Δt . Huh? Usually, naught (the subscript 0 in Δ t 0) indicates some universal thing, which would suggest it would be time at no velocity, i.e. maximum rate of time. But the only way this makes sense (algebraically AND intuitively) is if Δ t 0 , in fact if the whole right-hand side of the top equation is all about ME. MY experience of time when I MYSELF move through space at this velocity. So Δt (left-hand side) is whatever time YOU observe as I whiz past you. So MY time is always less than YOUR time. Ti...
