Photons cannot slow down but you could be right about
them losing energy over time. Lengthening the wavelength
of a photon is certainly a loss of energy. That could
explain the red-shift of light from distant galaxies.

"Optics", by Hecht, 4th edition, Page 52:
"Photons are stable, chargeless, massless elementary
particles that *exist only at the speed of light*."

This is a humbling discussion!

Hadn't thought about it in terms of increasing the wave-length, but you are
now messing with some of my basic assumptions about the universe with the
obvious implication being its size and age. We might be able resurrects the
steady state model!

Question: If photons are stable, chargeless, massless elementary particles,
how do they react with anything?
