This is almost certainly the solution to many of the problems that have arisen in cosmology. The major equations for gravity have known to be amenable to solutions other than the inverse-squared solution, and in particular that an inverse-linear component is viable, too. Einstein himself had considered such a solution, if I recall correctly. An increasing number of physicists are starting to investigate this, it appears. I spoke at length with one of them who works at MIT about four years ago, and there are several possible ways to validate this and discern whether it fits better than simple inverse-square. This is the first time I’ve seen a local solar system possibility though. The cosmological consequences involve that parts of the universe exist outside of the “visible” because they are too far away, not because they are “hidden, ‘dark’ matter”.
I believe that I will live to see this inverse-linear component of gravity confirmed, and the (NYSlimes consensus-LOL) “dark matter” hypothesis wiped out.
I'd think that would be the biggie here. It could be investigated with existing gear.
