In one sentence

Modern attempts by Paul Marmet, Lyndon Ashmore, and others have proposed specific plasma-based or electron-scattering tired-light mechanisms, but none has matched the combined surface-brightness, time-dilation, and CMB constraints.

Fritz Zwicky proposed in 1929 that photons gradually lose energy as they traverse intergalactic space, producing the observed redshift-distance relation without requiring cosmic expansion.

Predictions

Modified tired-light spectra in electron-photon interactions that could in principle be measured in plasma columns
Static universe surface brightness scaling distinct from expansion-based predictions

Redshift proportional to distance with no need for cosmic expansion
Static universe consistent with Hubble's law
No time dilation of distant events (a key contrast with expansion-based models)

Where it breaks

Fast radio burst observations constrain intergalactic electron columns inconsistently with Marmet's model
No revival has reproduced both Tolman surface brightness scaling and SN Ia time dilation simultaneously
Has not been integrated into a quantitative cosmological model fitting CMB, BAO, and SNe together

Provides no specific microphysical mechanism
Any scattering process would necessarily blur distant images, contradicting observations of sharp distant galaxies and quasars
Cannot account for the CMB, time dilation, or precision cosmological tests

Key unresolved problem

The three-test problem: no revival passes all three checks at once, how distant galaxies dim with distance (the Tolman surface-brightness test), the stretched-out timing of distant supernovae, and the thin spread of intergalactic electrons now measured by fast radio bursts.

The blurring problem: no physical process, no microphysical mechanism, can slowly bleed energy from light over cosmic distances without also knocking the light off course and smearing the sharp images of distant galaxies and quasars.
