Photons and the speed of light

Yes. There is no elapsed time in the photon’s frame between creation and absorbtion.

But because of the length contraction that also occurs at high speeds A and B are actually separated by zero space in the frame of the photon. So, of course it takes no time to travel between them from the photon’s perspective.

Of course, those equations don’t really work for v = c very well, just for v < c.
