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?
D = c/H0
gives the distance at which the Doppler shift would reduce the frequency of incoming light to zero. Answers can then address whether at some point in the future when there is more history since opacity, this limit might apply. $\endgroup$
