cosmology - The range of light


It occurs to me that the empirical evidence shows that there is a point out in space where light stops coming from.


Putting aside the expansion of the universe for a second, and focusing strictly on the evidence:




  • what would the universe look like if light had a finite range?





  • isn't that what the universe looks like?




Recall Hubble's Law,$ v = H_0D$


The range of light is $H_0 D = c$


Also recall that Edwin Hubble stressed the point that $v$ is apparent recessional velocity. It is the apparent recessional velocity, not the actual recessional velocity. He proposed that rather than Doppler shifts, these redshifts are a "new principle of nature".


Ignoring the theories and strictly examining the empirical evidence, does it make sense that light could have a finite range?
