Zero gravity, often depicted in science fiction and space documentaries, is a fascinating concept that sparks curiosity and ...

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.

If gravity reversed on the sun, McCluskey said he’d be scared because it is the only thing keeping the sun together. Nuclear fusion, inside the sun, pushes outward. Without gravity, the sun would ...

Evidence is mounting that cosmic dark energy, long thought constant, may weaken with time - potentially altering the fate of ...

Astronomers have announced the discovery of A11pl3Z, a massive new interstellar object entering our solar system.

Drag (air resistance) opposes acceleration due to gravity. In a vacuum, such as on the Moon, both objects will hit the ground at the same time. How does gravity work?

Finally, the Earth moves a little bit beyond one complete revolution, so the stick again points towards the sun for a second ...

According Harvard physicist Avi Loeb, the object - which originated in interstellar space - was spotted by astronomers ...

The field of advanced propulsion and gravity manipulation has long captivated the curiosity of scientists, engineers, and ...

“Low-Acceleration Gravitational Anomaly from Bayesian 3D Modeling of Wide Binary Orbits: Methodology and Results with Gaia Data Release 3” published in the Astrophysical Journal on 27 May 2025 ...

To “hear” the gravitational force on their 0.43-milligram particle, ... is how they are able to get the temperature so low and maintain such exquisitely low acceleration noises,” Adhikari says.

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 ...
