Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...

Researchers have redetermined the gravitational constant G using a new measurement technique. Although there is still a large degree of uncertainty regarding this value, the new method offers great ...

A human tightrope walker is able to walk the rope only in one dimension, forward or backward. But an ant can access an ...

The gravitational constant G determines the strength of gravity—the force that makes apples fall to the ground or pulls the Earth in its orbit around the sun. It is part of Isaac Newton's law of ...

Measuring gravitational analogues of quantum phenomena could lead to high-precision measurement of gravitational forces, according to a theoretical proposal. Micromuffins. The 1-µm-wide ...

In a bold step toward solving one of science's most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

Generalized Proca theories constitute an extension of Einstein’s gravity by introducing a massive vector field endowed with carefully chosen derivative self-interactions. These interactions are ...

Quantum theory and general relativity have long described the universe with incompatible languages, one speaking in probabilities and the other in smooth curves of spacetime. A new line of work argues ...

The odds of the bet Jonathan Oppenheim made in 2023 are generous, even at 5000 to 1. But if he wins, it could transform our view of the universe. The physicist is wagering that space-time, and ...
