Wide binary stars with separation greater than about 2000 astronomical units are interesting natural laboratories that allow a direct probe of gravity at low acceleration weaker than about 1 ...

The breakdown of Newtonian gravity at low acceleration would mean a scientific revolution whose full implications are immeasurably far-reaching. Because of this importance and considering other ...

It is mysterious to many scientists why gravity is boosted by about 40% when the internal acceleration between the orbiting pair of stars is weaker than about 0.1 nanometer per second squared.
