At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the ...

Quantum physics once shocked scientists by revealing that particles can behave like waves—and now, that strange behavior has ...

A new recipe of "quadratic gravity" could help to better define the picture of the Big Bang and the singularity that existed ...

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 ...

Measuring the strength of gravity is extraordinarily difficult, and different experiments have always disagreed – but a new ...

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 ...

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.

Only about 5% of the universe is composed of normal matter that we can directly observe, while the remaining 95% is widely ...

Dead stars may produce intense flashes of light through the power of gravity itself, researchers have demonstrated. Understanding this phenomenon could reveal new insights about some of the largest, ...

(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 ...

After a 10-year effort, physicists got a value for “Big G” that does not settle the debate over one of nature’s hardest numbers to nail down.

Rumours that Earth's gravity suddenly disappeared for a few seconds have circulated widely on the Internet lately. This rumor is associated with 12 Au.
