This thread seems to have got to the point where it is (again) worth noting that life is complex - it has real and imaginary parts. (The groans can be heard even from here). Slightly closer to real world is the photon's unreal world. >From a photon's point of view: All photons must [tm] travel instantaneously anywhere, but cannot travel at all, and indeed never need to as any given photon is instantaneously everywhere, as they all are. No photon gets to anywhere before or after any other one. Indeed, there is no before or after. No here or there. No then and now. Just because we see things differently than they do, who's to say they are wrong? :-) Russell --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
