Physicists searching for a better understanding of quantum gravity stumbled upon something unexpected: the defining ...

Trying to solve quantum gravity is frustrating. We have made tremendous progress in quantum theory, but it seems that every time we find a new quantum technique, there's a reason it doesn't quite work ...

String theory offers a unified framework in which the fundamental constituents of nature are one-dimensional objects whose vibrational modes give rise to particles and forces. By embedding gravity ...

A new study just added an interesting twist to the complicated history of the physics theory.

The gauge bosons of the standard model of particle physics are responsible for three of the four known forces in the universe ...

VATICAN CITY (RNS) — Renowned physicists, including two Nobel Prize winners, will gather at the Vatican Observatory near Rome next week to ponder the unresolved mysteries of the cosmos and to honor ...

The original version of this story appeared in Quanta Magazine. String theory captured the hearts and minds of many physicists decades ago because of a beautiful simplicity. Zoom in far enough on a ...

Scientists have achieved two major breakthroughs: experimentally uncovering how quantum order collapses in real-world environments and proposing new gravity models that could replace the Big Bang ...

Waterloo scientists have developed a new way to understand how the universe began, and it could change what we know about the Big Bang and the earliest moments of cosmic history. Their work suggests ...

Noncommutative quantum cosmology investigates the implications of replacing the ordinary commutative algebra of spacetime coordinates with a deformed, noncommutative structure. By introducing a star ...

Dr. Niayesh Afshordi, professor at the University of Waterloo and Perimeter Institute, draws the renormalization group flow for quadratic quantum gravity (University of Waterloo). Waterloo scientists ...
