Physicists claim they may have found a long-awaited explanation for dark energy, the mysterious force that's driving the accelerated expansion of the universe, a new preprint study hints. Their ...

It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is described extremely well by quantum theory, while the world of gravitation ...

Recent decades have witnessed remarkable progress in establishing rigorous mathematical frameworks for quantum field theory (QFT), conformal field theory (CFT), quantum gravity and string theory.

DURHAM, N.C. – Using lasers to contain some ultra-chilled atoms, a team of scientists has measured the viscosity or stickiness of a gas often considered to be the sixth state of matter. The ...

For more than a century, gravity and quantum physics have stubbornly resisted a common language, one describing the smooth ...

Tiny but ageing neutrinos can be used to test the very foundations of quantum theory at unprecedented cosmological time scales Schrodinger’s skinniest kittens Must the Schrodinger’s Cat be fat enough ...

Last month, the Dark Energy Spectroscopic Instrument (DESI) collective reported that dark energy is evolving—specifically weakening—and it could help provide the first observational evidence of string ...

As physicists search for a theory of quantum gravity, new results show that classical gravity can still interact with quantum fields to allow matter to become entangled. A new discovery suggests ...

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 ...

"God does not play dice." This famous remark by Albert Einstein critiqued the probabilistic nature of quantum mechanics. Paradoxically, his theory of relativity has become an essential tool for ...

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