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

Quantum mechanics and general relativity are the two pinnacles of 20th-century physics. In their respective fields, ...

Loop quantum gravity (LQG) is a non-perturbative, background-independent approach to quantising spacetime that seeks to merge the principles of quantum mechanics and general relativity. In this ...

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

Researchers at TU Wien have integrated quantum physics with general relativity, revealing significant departures from ...

Spacetime itself would also need to be “quantized,” or broken down into constituent parts. This is what the notorious string theory attempts to do, as does loop quantum gravity, currently considered a ...

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

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 ...

In a new Physical Review Letters study, researchers propose an experimental approach that could finally determine whether gravity is fundamentally classical or quantum in nature. The nature of gravity ...

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