Does this mean that eventually light from the most distant and earliest parts of the universe will shift into the radio spectrum? What after that?
Bear with me as someone with little formal training in physics. If photons do not age or have any time effect due to their existence at light speed, how can they lose energy unless they encounter something to which impart that energy (presumably stopping in the process)? And why would they lose energy traveling in space?
