Tired light hypothesis
http://user.astro.columbia.edu/~gbryan/C3602_2011/C3602_PS2.pdf WebThe tired light hypothesis states that the universe is not expanding, but that photons simply lose energy as they move through space (by some unexplained means), with the energy loss per unit distance being given by the law (2.39) where K is a constant.

WebMay 6, 2024 · According to the tired light hypothesis, ... the idea of tired light cosmology, where redshift was due to light losing energy as it traveled through space, was discredited … WebZwicky suggested several possible physical mechanisms (mostly scattering) that would cause this to happen. The simplest version of the tired light hypothesis assumes a decrease in photon energy with distance given by E (x) = E_0 e^-x/R_0 so that the energy loss per distance is dE/d = -E_0/R_0 e^-x/R_0 assuming that E_0/R_0 is a constant.
WebJul 16, 2014 · The best argument against tired light is that if the redshift was caused by an interaction between light and matter, there would be a frequency dependence of this interaction, as light interacts with matter differently when it is at different frequencies.
