How do redshifts support the big bang theory
WebAug 11, 2024 · The Big Bang Hypothesis - which states the universe has been expanding since it began 14 billion years ago in a hot and dense state - is contradicted by the new James Webb Space Telescope images, writes Eric Lerner. Web(a)The redshifts of distant galaxies are a consequence of the wavelength of light stretching during its journey to us. (b)All, or almost all, clusters of galaxies move away from each other. (c)Everything used to be much closer together and hotter than at the present time. (d)The matter density of the Universe is decreasing with time.
