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 ...

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 ...

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

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, ...

(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 ...

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 ...

On the surface, it would be considered counterintuitive for an animal such as a snake to stand upright since the snake lacks ...
