3 years ago The the redshift-distance relation is the observed fact the hypothesis comes from.
The idea is to add a new class of geodesics to spacetime for massless particles, which are equal to the null geodesic at non-cosmological scales, ie HD=0, but then diverge.
The geometry of spacetime with this new class of geodesic would like this:
A horizontal line that crosses all photon geodesics would show photons at different frequencies, just as we observe at cosmological scales.
" red shift isn't possible without clock desynchronization, ie, you will see the source's clock run at a slower speed than your own. Coherent red shift is not logically even possible without clock desynchronization. But clock desynchronization is fundamentally incompatible with your steady state universe for two distant observers who are stationary relative to each other. "
