(unindenting)You do know that general relativity (I think it's that one) says (and this has been confirmed experimentally) that time is affected by gravity? Transmissions between Earth and satellites have to account for the fact that the clocks in the satellites are running at a different rate to clocks on Earth, due to the lower gravity where the clocks are. Time passing at different rates ''is'' a real phenomenon. [[User:Philip J. Rayment|Philip J. Rayment]] 23:26, 13 May 2007 (EDT)
Yes, I agree. But it's only significant when you're near a very massive object. Out in empty space, which is where the light spends virtually all of its time in transit, the effect is so small that it can be neglected. We could probably estimate how small just from the 1/r^2 law of gravity.--[[User:Mackronking2|Mackronking2]] 00:43, 14 May 2007 (EDT)
