You sure that's a "valid" reason?

Photons don't have any mass, doo they? And they still obey the limit.

Plus - and admittedly I'm sketchy on this - when they talk about "space" expanding, it seems like what they really mean is "the extent of matter" expanding. Otherwise, like someone else here asked, "expanding into what?".

No, it's really the space expanding.

Photons (i.e.light) do have mass. There is an experiment setup that you could buy that looks like a light bulb with a sort of windmill inside of it, that proves it. I'll see if I can find a link.
