"In September of 2016, a new study by the Case Western University Astronomy department was published claiming
they had found a new law of physics correlating orbital velocity with the amount of visible and dark matter.
In their paper's conclusions, it is noted that an as yet unknown change in Newton's law of gravity could possibly explain these findings.
These exciting findings were predicted by similar papers on Sky's the Limit but are more clearly summarized in the newer "geometric consequences..."
One study is essentially a math paper in need of astronomical proof, and the other Case Western study is an astronomical observation looking for a comprehensive mathematical explanation. We believe each paper supports the other. The Case Western study is therefore presented below."
