In a new study, that’s what Arto Annila, Physics Professor at the University of Helsinki, is doing. The basis of his argument, which is published in a recent issue of the Monthly Notices of the Royal Astronomical Society, lies in the ever-changing way that light travels through an ever-evolving universe.

“The standard model of big bang cosmology (the Lambda-CMD model) is a mathematical model, but not a physical portrayal of the evolving universe,” Annila told PhysOrg.com. “Thus the Lambda-CMD model yields the luminosity distance at a given redshift as a function of the model parameters, such as the cosmological constant, but not as a function of the physical process where quanta released from a supernova explosion disperse into the expanding universe.

“When the supernova exploded, its energy as photons began to disperse in the universe, which has, by the time we observe the flash, become larger and hence also more dilute,” he said. “Accordingly, the observed intensity of light has fallen inversely proportional to the squared luminosity distance and directly proportional to the redshifted frequency. Due to these two factors, brightness vs. redshift is not one straight line on a log-log plot, but a curve.”

As a result, Annila argues that the supernovae data does not imply that the universe is undergoing an accelerating expansion.

Light curves past an anisotropy of energy density at a minimum
distance ro along the path where equal arcs rI (colored) are swept at equal
times, i.e., rZ is a constant

Using Maupertuis’ form of the principle of least action, Annila has calculated that the brightness of light from Type 1a supernovae after traveling many millions of light-years to Earth agrees well with observations of the known amount of energy in the universe, and doesn’t require dark energy or any other additional driving force.

Indeed.
I didn't hear before of him, but it looks like the guy is working on this theory from quite some time:

Let's see if someone will take the challenge to stress test it ad how well it will react.

Should I choose, makes much more sense his theory than the whole dark matter wagon.
