Physicists have long suspected that there is a layer of physical reality beneath quantum theory and a new mathematical model unveils just how strange it might be ...

Trying to solve quantum gravity is frustrating. We have made tremendous progress in quantum theory, but it seems that every ...

In the strange world of quantum mechanics, objects can exist in several states at once. This concept, called superposition, is one of the most puzzling features of quantum theory. A particle, for ...

Scientists have pulled off a mind-bending quantum experiment that sounds almost impossible: they showed that tiny metal ...

Theories of quantum mechanics predict that some particles can exist in superpositions, which essentially means that they can ...

The gravity quantum field is calculated in flat spacetime. The curved classical metric is calculated using the expectation value of the gravity quantum field. At long last, a unified theory combining ...

The implications of quantum mechanics suggest reality isn't as solid as we think it is, but physicist David Bohm had a spin ...

Two recent experimental advances are probing the foundations of quantum mechanics in unprecedented ways. Researchers have demonstrated novel methods to test Bell inequalities and search for ...

The force we experience most intimately remains the most mysterious. Physicists understand how vast migrations of particles called photons light up our homes, and how swarms of “gluon” particles hold ...
