CE425: Tired light

Claim CE425:

Response:

1. The tired light model does not account for time dilation observed in supernova light curves. A supernova that takes 20 days to decay will take 40 days to decay at a redshift of z=1.
   
   
2. The tired light model does not produce the blackbody spectrum of the cosmic microwave background (CMB). The tired light model says that the CMB is highly shifted light from stars, but stars do not produce the perfect blackbody spectrum that we see in the CMB.
   
   
3. The tired light model fails the Tolman surface brightness test [Lubin and Sandage 2001].
   
   
4. There is no mechanism which can account for tired light. No known interaction can degrade a photon's energy without also changing its momentum.
   
   
5. The Big Bang model explains other observations in addition to expansion red-shift and the cosmic microwave background.
   • the abundance of light elements, predicted from reactions that would occur during the first three minutes of the Big Bang.
   • the darkness of the night sky (Olber's paradox)
   • isotropy and homogeneity -- the universe looks pretty much the same in all directions, and our location isn't special.
   • radio source and quasar counts vary with age, showing the universe has evolved.
