For over a century, physicists have been trying to answer one of the most profound questions in science: Can gravity be unified with the quantum world? While the main model describes the ...

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 secret to directly detecting dark matter might be blowin’ in the wind. The mysterious substance continues to elude scientists even though it outweighs visible matter in the universe by about 8 to ...

As far as we know, our physical world is governed by four fundamental forces: electromagnetism, weak and strong nuclear forces, and gravity. Apart from playing with bar magnets or marveling at the ...

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 ...

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 ...

A longstanding goal in physics has been to link general relativity with quantum theory and so unify the forces of nature. Theories of quantum gravity, however, are plagued by the weak theoretical ...

Physics is supposed to be the most reliable science. Gravity works the same way everywhere. Light always travels at the same speed. The laws are universal—that's literally what makes them laws. For ...

Big G, gravity, is the oldest fundamental constant in physics and the least clearly defined. One scientist has spent a decade ...
