Gravity doesn’t discriminate. An experiment in orbit has confirmed, with precision a hundred times greater than previous efforts, that everything falls the same way under the influence of gravity. The ...

Newswise — A new study published in the journal PRX Quantum demonstrates how a network of quantum computers employing optical clocks can probe gravitational effects on quantum systems. The study’s ...

Quantum mechanics and Einstein's general relativity explain how the Universe works at the tiniest and largest scales, ...

EL SALTO, Mexico — Thirty minutes before totality, a large cloud dared to park in front of the sun. The sunlight split against the puffs to create a beautiful rainbow, but it was a nuisance for the ...

For more than a century, Einstein’s relativity has set a hard speed limit for the universe, with light as the ultimate traffic cop. Now a new generation of warp drive research, built from normal ...

This video examines whether modern physics has revived the 19th-century idea of the “aether” — the invisible medium once thought to carry light — and explains how contemporary theories changed our ...

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 ...

Addressing a controversy first raised around 1910, two physicists have performed experiments with the aid of an engineer that validate anew the special theory of relativity’s limitations on the speed ...
