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 ...

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

TU Wien researchers have uncovered a quantum twist to the paths particles take through spacetime — one that could finally reveal which theory of quantum gravity fits nature. Their new “q-desic” ...

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.

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

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 ...

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 ...

String theory captured the hearts and minds of many physicists decades ago because of a beautiful simplicity. Zoom in far enough on a patch of space, the theory says, and you won’t see a menagerie of ...

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 ...

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 ...
