Quantum foam's implications for spacetime fluctuations are crucial for addressing key questions in physics, from black holes ...

Assistant Professor Haocun Yu is something of a scientific diplomat. In a recent Physical Review Letters publication, she and her colleagues show how a tabletop experiment can bring together two ...

Researchers at Hiroshima University have developed a realistic, highly sensitive method to detect the Unruh effect—a long-predicted phenomenon at the crossroads of relativity and quantum theory. Their ...

The proposed BMV experiment could test whether gravity is quantum, a breakthrough that may lead to quantum computers and ...

Physics has a problem—their key models of quantum theory and the theory of relativity do not fit together. Now, Dr. Wolfgang Wieland from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) is ...

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein's general relativity. One explains the tiny world of particles; the other describes ...

What exactly is … everything? What is space-time? At one extreme, you’ve got the weird rules of quantum physics that deal with subatomic particles. At the other extreme, you’ve got the vast expanses ...

Scientists think a new framework for quantum gravity could offer clues about a mysterious 5th fundamental force of nature.

(University of Birmingham) The quantum world is mind-bogglingly counterintuitive: at the smallest scales, basic physical ...

The first step toward quantum gravity, the "holy grail of physics," may be hiding in a quantum recipe to cook up black holes. That's the suggestion of new research that adds quantum corrections to ...
