We often marvel at the genius of Albert Einstein, a physicist who revolutionized our understanding of the universe. Yet, even ...

A new theory suggests that the unification between quantum physics and general relativity has eluded scientists for 100 years because huge "fluctuations" in space and time mean that gravity won't play ...

Textbooks give strange, imprecise explanations of where things happen in quantum mechanics. Consistency with gravity needs a fresh approach.

Quantum gravity strives to reconcile the seemingly disparate realms of general relativity and quantum mechanics. Central to this endeavour is the realisation that classical concepts of spacetime may ...

When you buy through links on our articles, Future and its syndication partners may earn a commission. An abstract illustration of quantum particles entangling. New research aims to unite gravity with ...

A new study reports on a deep new probe into the interface between the theories of gravity and quantum mechanics, using ultra-high energy neutrino particles detected by a particle detector set deep ...

Understanding the universe's building blocks, the Standard Model categorizes particles and explains forces, yet leaves ...

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 ...

Over a century ago, two theories were put forward to explain all of reality: quantum mechanics and general relativity. Both have been refined and improved over decades and extensively tested. They are ...

(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 ...

The accelerating expansion of the universe could be explained by modifying general relativity so that gravity has mass – or so thinks a small group of physicists. Matthew Francis reports What lies ...
