For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other.

Mind = blown.

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might ...

Physicists are quietly testing wild new theories that treat a hidden fifth dimension as more than science fiction, suggesting ...

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 ...

The image depicts an experiment in which heavy particles(illustrated as the moon), cause an interference pattern (a quantum effect), while also bendingspacetime. The ...

This episode of the Physics World Weekly podcast features Alex May, whose research explores the intersection of quantum gravity and quantum information theory. Based at Canada’s Perimeter Institute ...

Quantum gravity and field theory represent a frontier where the principles of quantum mechanics are reconciled with Einstein’s description of gravity. Researchers are seeking a consistent framework ...

(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 ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.
