can you move fast enough towards light so that it has a period of 0?
at what speed must i be moving towards a beam of light in order for the wavelength to have a period of 0?
would it be the speed of light? would it need to be greater than the speed of light? if so, what period would it be at if i were movign at the speed of light?
i mean, maybe the question is dumb, and the answer is obvious that it would be the speed of light, but with relativity, the answer seldom turns out to be obvious i find.

ya.. but light does.
it's almost kind of predictable that would be the case, and yet, an interesting thought.
and predictably i guess again, as v→-c it goes to infinity.
here's a related question. how do we know whether or not there's a bunch of stuff in outer space that's moving away, or towards us, by rates of speed that would yield a period, as of yet, undetected by us? or detected by us, and yet, unrecognized.
