The Hubble Ultra Deep Field is an image of galaxies that are in excess of 10 billion light years away. If tired light was a correct explanation, these galaxies would appear blurred in comparison to closer galaxies. That they do not rules out the suggestion that scattering processes are causing the redshift-distance relation.
Big Bang

The Big Bang is a physical theory that describes how the universe expanded from an early state of high density and temperature. Various cosmological models based on the Big Bang concept explain a broa

…in particular John Quincy Stewart, William Duncan MacMillan, and Walther Nernst. Tired light mechanisms were among the proposed alternatives to the Big Bang and the Steady State cosmologies, both of which relied on the general relativistic expansion of the universe of the FRW metric. Through the middle of…
