I appreciate that this may be the 100th time this is asked but I am yet to see an answer which addresses the question head on. Given that reaching light speed creates both a length and time singularity; both length and time amount to zero for the propagating wave/photon. Why does that photon nevertheless require (around) 8 minutes to travel from the sun to our eyes? (or perhaps a more correct way to phrase that would be, why do we require 8 minutes of our perception of time for the light to travel the distance which we perceive as being between the sun and the earth?) Basically I am asking why is such travel not simply instantaneous from all perspectives rather than 'c' from all perspectives? And as an afterthought, if 'c' is constant from all perspectives, is it also constant relative to the wave/photon itself?
