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 ...

Scientists have taken lasers beyond light and into the realm of sound, creating a breakthrough “phonon laser” that ...

Gravity has become an unlikely viral villain, blamed for an imagined global blackout in which the planet briefly lets go of everything that is not nailed down. At the same time, some of the most ...

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 ...

We all know gravity as the invisible force that keeps us grounded. But what if it's not a force at all? What if it's a function? One physicist believes gravity might actually be one of the strongest ...

"Studying quantum aspects of gravity experimentally doesn't just require deep understanding of physics—relativity, quantum mechanics—but also demands hands-on expertise in system design, ...

Einstein's theory of general relativity explains that gravity is caused by a curvature of the directions of space and time. The most familiar manifestation of this is the Earth's gravity, which keeps ...

(via Sabine Hossenfelder) Last year, Jonathan Oppenheim’s theory of post-quantum gravity was the only theory that made it into my Best of 2024 summary. Post-quantum gravity is one of the most ...

Do dead stars glow? A strange gravitational phenomenon could be generating enormous amounts of light around neutron stars, new research suggests. When you purchase through links on our site, we may ...
