Physicists at Kyushu University in Japan have outlined a technique that could bring one of the most elusive goals in modern ...

Physicists have long suspected that gravity might have a hidden quantum side, but for decades the idea has been more mathematics than measurement. A new proposal for a tabletop experiment now suggests ...

In quantum physics, objects can exist in multiple states at the same time—a phenomenon known as quantum superposition, where ...

A key question in physics is whether gravity follows quantum rules, but testing this is difficult because gravitational ...

A Gravity Theory That Could Rewrite the Universe’s First Moments The first fraction of a second after the Big Bang has always posed a problem. Physics can describe a great deal about the universe ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works extremely well in its own domain: Quantum theory explains how atoms and ...

Physics is this close to understanding the entire universe. And what lives in this gap? Many physicists think it’s the elusive graviton—the quantum particle of gravity—whose discovery will finally ...
