The theory, which emerged in the 1970s as a way to unify the fundamental forces of nature, has profoundly shaped the landscape of particle physics

A proposed experiment to swap fundamental properties between photons carries profound implications for our understanding of reality itself

Physicists attempting to unify the theories of  gravity and quantum mechanics have long thought practical experiments were out of reach, but new proposals offer a chance to test the quantum nature of gravity on a tabletop

High-pressure hydrogen materials could be a step toward a new era of superconductivity

Some physicists claim that the popular landscape of universes in string theory may not exist

Hundreds of researchers in a collaborative project called “It from Qubit” say space and time may spring up from the quantum entanglement of tiny bits of information

Einstein’s thought experiments left a long and somewhat mixed legacy of their own
