Scientists have spotted the first hints that Einstein's formulation of gravity operates in the quantum realm.

Wide binary stars as direct probes of the nature of gravity at low acceleration weaker than about 1 nanometer per second squared have been hotly debated. The nature of gravity at such low acceleration ...

Physicists have proven a 100-year-old prediction of relativity by showing that Einstein's equivalence principle holds at ...

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 ...

Physicists split an atomic wave between free fall and a stationary path, revealing a quantum phase predicted nearly a century ago.

Caltech engineer Mory Gharib was poring over the digitized notebooks of Leonardo da Vinci one day, looking for sketches of flow visualization to share with his graduate students for inspiration.

Dark matter detection just expanded: a Physical Review D paper published September 9 proposes using LISA, TianQin, and Taiji ...
