One way to get the universe to expand is with dark energy that pulls at the matter of the galaxy separating it or equivalently for space-time to not be perfectly flat. An alternative, in principle, would be for the gravitational pull between objects like galaxies and galactic clusters to be suppressed for some reason relative to the "GR without cosmological constant" prediction. Instead of being tugged apart from the outside, these objects would not be held together a strongly as expected. For example, perhaps gravity is a very long range, but not infinite range force, or perhaps dark matter absorbs gravitons thereby reducing the amount of gravitational pull that can escape the system with dark matter in it which could also address the "coincidence problem". Lots of published academic work explores the dark energy possibility. Is anyone aware of any peer review work/academic pre-prints that explore the suppressed gravitational field possibility as an explanation for the phenomena commonly attributed to dark energy? This question is inspired by ideas sketched out on a back of napkin basis by A. Deur in published peer reviewed work, but the question is more general.
