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

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 ...

Quantum entanglement is a state in which particles are entwined with each other. In this entwined state, the properties of ...

A series of theoretical results from some of the field’s most prominent physicists now supports a striking idea: quantum ...

With the help of a new experiment, researchers have succeeded in confirming a ten-year-old theoretical study, which connects one of the most fundamental aspects of quantum mechanics -- the ...

An experiment with a toy universe made up of extremely cold atoms shows how time can emerge from quantum interactions, ...

Quantum nano-mechanics. Quantum jumps in atomic physics. Continuous transitions between quantum states in quantum‒classical mechanics for molecular and chemical physics involve both chaotic (dozy ...

A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the universe would fall apart if it all remained unchanged. This theory tries to ...

Faster-than-light particles have spent decades in physics as both temptation and warning. They offered a way to test the ...
