This gives us z e q = ρ matter 0 ρ radiation 0 − 1 ∼ 3400.

WebIn the conventional view, “the light traveling from the supernova towards Earth is stretched because the universe is expanding and so space also expands. The stretched light’s wavelength is shifted towards the red part of the spectrum.”2 This is called cosmological redshift and it is based on fallacious data.
