A variation on the theory of quantum gravity — the unification of quantum mechanics and Einstein's general relativity — could help solve one of the biggest puzzles in cosmology, new research suggests.

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 ...

The story begins with the black hole information paradox. According to relativity, anything that falls into a black hole is ...

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 ...

A rift runs deep through the heart of physics. The general theory of relativity, which describes gravity, clashes with quantum physics. In an effort to seal that physics fissure, untold numbers 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 ...

Quantum gravity is the missing link between general relativity and quantum mechanics, the yet-to-be-discovered key to a unified theory capable of explaining both the infinitely large and the ...

The University of California opened its doors in 1869 with just 10 faculty members and 40 students. Today, the UC system has more than 295,000 students and 265,000 faculty and staff, with 2.0 million ...

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 ...

Forget the Turing test. In Sam Altman's world, the only verdict that matters comes from physicist David Deutsch.
