A new sound-based laser could measure gravity with unprecedented precision and reshape navigation technology.

A device that can measure the gravitational force on a particle that weighs less than a grain of pollen could help us understand how gravity works in the quantum world. Despite keeping you stuck to ...

After a 10-year effort, physicists got a value for “Big G” that does not settle the debate over one of nature’s hardest numbers to nail down.

Scientists have taken lasers beyond light and into the realm of sound, creating a breakthrough “phonon laser” that manipulates tiny vibrations at the quantum level. By dramatically reducing noise in ...

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 ...

Traditionally, scientists have measured gravity’s influence on atoms by tracking how fast atoms tumble down tall chutes. Such experiments can help test Einstein’s theory of gravity and precisely ...
