A new discovery suggests gravitational fields can enable matter to become quantum entangled — and that's even if the concept ...

A recent experiment at Fermilab has delivered intriguing results that challenge standard predictions, adding fuel to the ...

Physics is this close to understanding the entire universe. And what lives in this gap? Many physicists think it’s the ...

Of the four fundamental forces of physics, gravity is the one we’re most familiar with in everyday life, but it’s also the only one that can’t currently be explained by quantum physics. Now scientists ...

In 1980, Stephen Hawking gave his first lecture as Lucasian Professor at the University of Cambridge. The lecture was called ...

ALMA reveals that gravity reorients magnetic fields in 17 young clusters, aligning them as gas collapses and accelerating ...

The best way to find buried treasure may be with a quantum gravity sensor. In these devices, free-falling atoms reveal subtle variations in Earth’s gravitational pull at different places. Those ...

The flow of time isn’t as consistent as we might think – gravity slows it down, so clocks on the surface of Earth tick slower than those in space. Now researchers have measured time passing at ...

Despite decades of searching, the "dark matter" thought to hold galaxies together is still nowhere to be found. Matthew Chalmers describes how some physicists think it makes more sense to change our ...

Even teeny objects obey the law of gravity. A gold ball just 2 millimeters wide, with a mass of about 90 milligrams, is now the smallest object to have its gravitational pull measured. Observations of ...

Last week, four lasers were projected into the sky above the European Southern Observatory (ESO) Paranal site in Chile. The ...
