I heard that null physics supports tired light as an explanation for the intergalactic redshift. Is this true?
Tired light, which trys to explain the intergalactic redshift purely in terms of the energy loss of individual photons, fails a number of observational tests. The most important of these is the broadened light curves of Type 1a supernovae. The intensity of the light from these explosions has a characteristic rise time and decay period, and it has been found that the greater a signal’s redshift, the broader (longer) the light curve, in direct proportion. Thus not only are photons redshifted, but the distance between them is also expanding over time. Further, the observed intergalactic redshift has no associated refractive or directional dispersion, and energy loss is proportional to photon energy. This means that it is not caused by the interaction between photons and any known form of matter or energy. Null physics shows, using the general theory of relativity, that the observed intergalactic redshift is consistent with the static spatial curvature of a nonexpanding universe.
