Physicists have long struggled to unite quantum mechanics—the theory governing tiny particles—with Einstein’s theory of ...

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 ...

A new theory of quantum gravity, which attempts to unite quantum physics with Einstein's relativity, could help solve the puzzle of the universe's expansion, a theoretical paper suggests. When you ...

Entropy. The word itself should cause insomnia. It means that matter and energy will degrade—ultimately leading to chaos in the universe—if things are left alone. So why is a new theory suggesting ...

Gravity is supposed to be the most familiar force in nature, yet at the deepest level it remains the least understood. A bold new line of research now argues that gravity is not fundamental at all, ...

A unified Theory Of Everything is the holy grail of physics, but gravity refuses to play ball. Now, a newly proposed theory attempts to unify Einstein’s theory of gravity with quantum mechanics – and ...

(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 ...

This video summarizes quantum gravity, highlighting the conflict between general relativity and quantum mechanics. It ...

A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the universe would fall apart if it all remained unchanged. This theory tries to ...
