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

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 ...

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

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 ...

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

A new study suggests that certain 'quantum collapse models'—which posit that wavefunction collapse happens spontaneously—could be tied to gravity, introducing a tiny intrinsic uncertainty in time ...

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 ...
