A bit more on the speed of light.... (this may bend your brain a little)
From a photon's perspective, the distance it travels could be stated as the linear distance between the point of emission and absorption multiplied by 1 divided by infinity... ie) zero.
The time it takes to do this journey (at the speed of light) is again, zero.
If you wanted to describe that as a velocity, ie) distance covered per unit of time, the answer would be zero divided by zero... it is meaningless trying to describe it this way.
Another way to say it is that the Universe has no size or time dimensions for an object travelling at the speed of light.
For all intents and purposes, the photon is a waveform that exists complete in its entirety, then collapses. It is not like a bullet that flies between two points, even though we experience it like that from our distorted frame of reference.
caveat: I may have mangled the language a little, but I believe the core of the principle explained above is essentially correct.
