I just saw this news article on the home page of the university I'm working in:
http://www.aalto.fi/en/current/news/2017-06-30/
It seems to be about a study that can potentially explain the redshift of distant stars with a mechanism that's related to the interaction of photons with the interstellar medium and doesn't require an expanding universe:
How plausible does this seem to you people? Is there any evidence in addition to the redshift of stars for an expanding universe? Cosmic background radiation seems to be quoted as one. Of course, in GR a constant average density universe is unstable, so the only alternative would be that our universe is getting smaller (if we assume GR is correct), and these results are too preliminary to make any conclusions from.

This prompts for further simulations with realistic parameters for interstellar gas density, plasma properties and temperature. Presently the Hubble’s law is explained by Doppler shift being larger from distant stars. This effectively supports the hypothesis of expanding universe. In the mass polariton theory of light this hypothesis is not needed since redshift becomes automatically proportional to the distance from the star to the observer”, explains Professor Jukka Tulkki.
