Erek - very true - you can see that in superconductor fluids - the spinning beaker. I love this one: you can spin the beaker but the fluid stays absolutely still. The nuclei of the atoms are still moving ,but the electrons have almost totally stopped. Dan - bingo - that's exactly the thing I thunk - anything "travelling at the speed of light" REALLY isn't moving at all - it's sitting still (f...rom its perspective) - there is no space, there is no time for it - its lifespan is over just as it begun. But we slow creatures get to see "slices of time", watching the universe unfold in extremely slow motion - rather like how houseflies must view us - statues they keep landing on over, and over, and over again, in the EXACT same spot...
