atzanteol, 9 miesięcy temu angielski Seems energy is not conserved. preposterousuniverse.com/…/energy-is-not-conserve… The thing about photons is that they redshift, losing energy as space expands. If we keep track of a certain fixed number of photons, the number stays constant while the energy per photon decreases, so the total energy decreases.
