Physicists have spent a century trying to reconcile the smooth fabric of spacetime in general relativity with the jittery ...

Among the many functions performed by skeletal muscles, an important one is maintaining our posture. If it weren’t for these muscles, Earth’s gravitational pull may make it difficult for us to stand ...

Their work introduces a new concept called q-desics, short for quantum-corrected paths through space–time. These paths ...

The idea that Mars could affect Earth’s climate sounds dramatic, since climate change is usually linked to cars, factories, ...

The late Michael Jackson was known for his choreographic ability to seemingly defy gravity — a skill often attributed to the music legend's astronomical footwear. A system for allowing a shoe wearer ...

For the first time, in a unique laboratory experiment at CERN, researchers have observed individual atoms of antihydrogen fall under the effects of gravity. In confirming antimatter and regular matter ...

Gravity and motion make time pass faster on Mars than Earth, reshaping navigation, communication, and future crewed missions.

Gravity, despite its pervasive influence, is the weakest fundamental force, easily overcome even by simple actions like lifting a pencil. While achieving and maintaining orbit requires significant ...

If you’re superstitious, a black cat in your path is bad luck, even if you keep your distance. Likewise, in quantum physics, particles can feel the influence of magnetic fields that they never come ...

It’s not often that you get a physical effect named for a baron. It’s also not often that physics demonstrations are made during naval maneuvers. That’s what makes the Eötvös effect so notable. The ...
