A conspiracy theory that spread on social media claims that gravity will disappear for seven seconds this August, and that NASA is aware that this will happen. A physics professor explains why this is ...

For decades, physicists have struggled to reconcile the laws governing the very small with those that describe the vast cosmos. Quantum mechanics rules subatomic particles, while general relativity ...

About 85 percent of the matter in the universe is thought to be dark matter, yet there is still no confirmed direct detection of any dark matter particle. Ground-based detectors, space-based ...

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 ...

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 ...

An Antarctic large-scale experiment is striving to find out if gravity also exists at the quantum level. An extraordinary particle able to travel undisturbed through space seems to hold the answer.

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 ...

The original version of this story appeared in Quanta Magazine. When it comes to understanding the fabric of the universe, most of what scientists think exists is consigned to a dark, murky domain.

(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 ...

Black holes can’t be formed from pure light. Quantum physics would curb their creation under any foreseeable conditions, a new study suggests. Typically, matter is responsible for black holes. They’re ...
