A new study reports conclusive evidence for the breakdown of standard gravity in the low acceleration limit from a verifiable analysis of the orbital motions of long-period, widely separated, binary ...
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 nanometer ...

The universe’s accelerating expansion has long puzzled physicists. For decades, dark energy, an unseen force thought to make up nearly 70% of the cosmos, has been the leading explanation. But a new ...
