Physicists have proven a 100-year-old prediction of relativity by showing that Einstein's equivalence principle holds at quantum scales.

Jonathan Oppenheim says scientists may be looking for answers to the biggest mystery in physics in the wrong place. According ...

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 ...

Diagrammatic representation of the entropic quantum gravity action. The action for gravity is given by the quantum relative entropy between the metric of the manifold and the metric induced by the ...

This video examines whether modern physics has revived the 19th-century idea of the “aether” — the invisible medium once thought to carry light — and explains how contemporary theories changed our ...

The Earth’s gravity, manifested as curvature in space and time, is expected to alter the rules of standard quantum theory. An experiment consisting of three quantum computers at different elevations ...

A seminal paper by Paul Dirac, who relied on mathematical intuition, laid the foundation for quantum electrodynamics. Paul Dirac once said that his theories are “built up from physical concepts which ...
