Using the axiom(s) that without space things do not exist and without time events do not occur, I would offer that a photon has aspects of space, time, and energy, but it crosses the Universe always in the present of its emission. When a photon arrives at a sensor it has no inertia, so it has no inertial mass. Something makes the photon different in spatial or temporal characteristics from other things that exist. I am convinced from the work of Haisch, et al that the something is the temporal aspect ... the time of a photon is planar time, not linear time. But then I’m also convinced that it is the temporal nature (linear time bound to the zero points) of the zero point field that gives masses their inertial mass and causes gravity, so you might want to just ignore what I write, for another fifty years to pass before utilizing these realities.
Well I hope I don't have to wait that long, for I don't expect I'd still be here fifty years hence!
Thank you, dear brother in Christ, for your further illumination of these issues.
