The weak gravitational pull on a particle just half the mass of a grain of sand has been measured for the first time. This most precise measurement of its kind is a breakthrough towards the quantum ...

A new crew of potential ripples in spacetime has just debuted — emphasis on the word “potential.” By loosening the criteria for what qualifies as evidence for gravitational waves, physicists ...

Around 37,000 citizen scientists combed through 430,000 images to help an international team of researchers to discover 29 new gravitational lens candidates through Space Warps, an online ...

Astronomers have reported a bumper crop of new gravitational wave detections. The 35 new signals, comprising the third Gravitational-Wave Transient Catalog (GWTC-3), help scientists probe the depths ...

Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at once, described by a mathematical object called a wavefunction.

The first detection of gravitational waves in 2016 provided decisive confirmation of Einstein’s general theory of relativity. But another astounding prediction remains unconfirmed: According to ...

Scientists review research on gravitational wave detectors as a historical example of quantum technologies and examine the fundamental research on the connection between quantum physics and gravity.

The fabric of spacetime may be frothing with gigantic gravitational waves, and the possibility has sent physicists into a tizzy. A potential signal seen in the light from dead stellar cores known as ...

Gravity is a ubiquitous part of our daily lives — whether we’re being tragically brought to our knees after tripping on the rug or gleefully jumping from a swing’s apex. But despite how common the ...
