"Solution to the Tired Light Theory" is an article by Glenn Borchardt published on 29 December 2025 on The Scientific Worldview, prompted by a reader's questions about how redshift is calculated.
Borchardt sets out his own account of why the cosmological redshift occurs, distinguishing it from the classic tired light proposal. His argument rests on the claim that the speed of light, like the speed of sound and every other wave motion, depends on the medium it travels through — so a wavelength stretched over intergalactic distance needs no expanding universe to explain it.
