AG * *The short answer is energy is destroyed by the expansion of the universe because electromagnetic waves with long wavelengths have less energy than electromagnetic waves with short wavelengths. But there's something deeper going on.* I see you want to be stupid. No one has ever shown that photons have spatial extent. The frequency is just a number that defines a photon's energy. Nothing to do with an extended wave. Just a number. The stretching of the wave as the universe expands is foolish explanation of the reddening. AG *It's a logical necessity that 2+2 be equal to 4, but there is no such logical necessity that energy be conserved.* On the contrary, in classical mechanics one can show that the sum of kinetic and potential energy is constant. AG * And if the energy was preserved I could ask "preserved by what?". * Stupid question. Its sum is the same before and after interactions. There's no "thing" that preserves it. I was speaking loosely when I asked what destroys it, and you were so anxious to prove me mistaken, that you couldn't resist shooting off your mouth. This list isn't the place for speculation. Ultimately, you're a conformist who hates any type of speculation.
