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 ...

New research suggests time could hold the key to resolving mysteries of gravity, quantum mechanics, and other phenomena in ...

In quantum mechanics, particles do not behave like everyday objects. Instead of existing in one clearly defined state, they ...

Only about 5% of the universe is composed of normal matter that we can directly observe, while the remaining 95% is widely ...

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

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

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 ...

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 ...

Physicists have long suspected that there is a layer of physical reality beneath quantum theory and a new mathematical model ...
