I have long wondered if the redshift were actually caused by decay of photons (the speed of the particle constant, but the wavelength decreasing). If so, the universe may not be expanding at all. If neither the speed nor the wavelength of light is constant, what do we really know?
Or that higher redshift is a property of younger matter as seen in the decreasing,
quantized redshift in successively more distant quasars ejected from Seifert galaxies.
Hey, guys, too much overthinking it here.
It’s simply obvious that redshift is caused by the Palin wave.
