Or is it how come a photon has the same lack of mass in the face of all expansion that has ever been? Wouldn't the pressure to become part of the larger emerging space cause the photon to acquire mass rather than maintain a lack of mass? Or is the lack of mass found somewhere else, like our mysterious dark matter missing mass problem? Seriously, perhaps all the missing mass is what the photon would have had in some other universe had that universe actualized.
Before you reply me to shreds, it's just a thought. A different way to look at an old standard. I just see a whole lot of mass with no particle associated with it and a whole lot of particles with no mass associated with it. Separated at birth perhaps?
Ok, I'm braced for it now. Thank you Pagan for bringing this to my attention. It would at least make for good fiction, I think.
