If we take a photon as our frame of reference is it safe to say that the universe moves relative to "Us" at the speed of light?
that is, something 300,000 kms away from us in the "direction" we are "travelling" in, will we reach it in 1 second, or rather since we're stationary, will IT reach US in 1 second?
so what of an object simply traveling towards us at 300,000 km/s (stationary) and an object traveling 450,000 km/s towards us (moving to intercept us at 1/2 light speed). in order to measure light speed as constant for both, we need to contract our distances or dialate our times in these cases. but why are we doing so in the first place?
i realize that relativity theorists will probably retort with some useless saying such as "you can't take the reference of the photon as your frame" or "time doesn't exist for photons, so space-time has no meaning" or something to that extent, but it would be nice if anyone had any interesting thoughts on the matter.
