Conventional Big Bang Theories and Tired Light Theories

The big bang or hot expanding model of cosmology finds strong support from the recession of the galaxies, that is, when we look out in the night sky, distant objects appear to be flying away from us. And also the cosmic microwave background - the fact that we are bathed in primordial light that bears evidence from and earlier, hotter, and denser period in the universe. Tired light is a class of hypothetical redshift mechanisms that was proposed as an alternative explanation for the redshift-distance relationship. Zwicky himself acknowledged that any sort of scattering of light would blur the images of distant objects more than what is seen.
