Had this idea when I was younger that maybe photons have some infinitesimal mass, but not exactly zero, and that’s why they travel at the speed they do.

Because anything with mass when accelerated toward the speed of light takes on infinite mass and hence has to slow down as there’s not enough energy to propel it.

But if a photon’s mass was 1/infinity, then 1/infinity * infinity might equal light speed. Anything bigger than 1/infinity can never reach light speed.

Maybe it’s a dumb idea to those versed in these things, but I’ve had it for a long time and figured I’d post it.
