Light takes about 1 1/4 seconds to reach the Moon, if I aim a laser at point X on the Moon and then move it to point Y also on the Moon it will take the usual 1 1/4 seconds after I moved my laser before anybody at point X observes that the light coming from Earth has gone off, and it will take the usual 1 1/4 seconds before anybody at point Y sees a light from Earth go on, and 2 1/2 seconds before anybody on planet Earth sees the spot of light at point X start to move. Nobody on the Earth or on the Moon has received or transmitted any information faster than light. If it was possible to transmit information FTL according to relativity you could send a message into the past, you could talk to the Bruce Kellett of yesterday and that would create paradoxes.* > *> "Non-local" does no mean that anything physical is transmitted FTL.* > *Being "local" means that there is a finite limit to the speed of PHYSICAL causality, and in this universe that speed seems to be the speed of light. * *>> What in the multiverse are you talking about?!

It's been known for hundreds of years that light beams with opposite polarizations treat polarizers in opposite ways, and it's been known since 1905 that light beams are made up of photons. None of this is controversial, it's physics 101. * John K Clark See what's on my new list at Extropolis <https://groups.google.com/g/extropolis> p1o -- You received this message because you are subscribed to the Google Groups "Everything List" group.
