Suppose that some physical "constant" that affects the global characteristics of atomic spectra varies continuously but otherwise is free to vary at will. Suppose that when this "constant" is at a maximum, energy (frequency) of spectral lines is at a maximum, and life evolves at a maximum rate. Then the reason we observe distant galaxies redshifted is that we happen to be at a local peak in this physical "constant". Why does this "constant" happen to be at a maximum here, because if it weren't then life would evolve somewhere else instead of here and we would be there instead of here looking at the Universe. I don't for a moment propose this theory, but it's hard to refute! Anybody want to try?
