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

For more than a century, physicists have been trying to reconcile the smooth geometry of gravity with the jittery ...

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

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 ...

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 ...

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 ...

Two teams of researchers working independently of one another have come up with an experiment designed to prove that gravity and quantum mechanics can be reconciled. The first team is a pairing of ...

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