Quantum theory and general relativity have long described the universe with incompatible languages, one speaking in ...

In the 18th century, the scientific world was drunk on Newtonian certainty. The universe was a clockwork mechanism, ...

A century-old debate ends as physicists prove Einstein wrong using single photons to test quantum theory with unprecedented ...

Quantum theory fails to explain how the reality we experience emerges from the world of particles. A new take on quantum ...

For close to a century, scientists have been trying to marry Albert Einstein’s General Theory of Relativity and quantum ...

Researchers have uncovered clear evidence of exotic quantum excitations inside a rare 3D spin liquid, validating decades of ...

It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is ...

A century ago, the Stern-Gerlach experiment established the truth of quantum mechanics. Now it’s being used to probe the clash of quantum theory and gravity. Before Erwin Schrödinger’s cat was ...

"This work is a step toward understanding how quantum mechanics and gravity work together, a major unsolved problem in physics." The first step toward quantum gravity, the "holy grail of physics," may ...

For decades, physicists have faced one of science’s greatest puzzles: merging quantum mechanics, which describes tiny particles, with general relativity, which explains the universe’s vast structures.

Researchers have developed a new quantum theory of gravity which describes gravity in a way that's compatible with the Standard Model of particle physics, opening the door to an improved understanding ...

TU Wien researchers have uncovered a quantum twist to the paths particles take through spacetime — one that could finally ...
