Quantum mechanics replaced the clockwork certainty of classical physics with something far stranger: a framework in which particles do not follow single, predictable paths but instead exist as clouds ...

A series of quantum physics experiments and theoretical papers now suggest that heat can flow spontaneously from a cold object to a hot one, provided the right quantum conditions are in place. This ...

A team at New York University has discovered a new form of time crystal that hovers using sound waves. Unlike ordinary matter, these crystals seem to behave in ways that don’t align with Newton’s ...

If spacetime is classical, it should undergo random fluctuations, which could in turn change the mass of objects by tiny amounts over time. One experiment the team suggests is that measuring an object ...

Where do you see patterns in chaos? It has been proven, in the incredibly tiny quantum realm, by an international team co-led by UC Santa Cruz physicist Jairo Velasco, Jr. In a new paper published on ...

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter. In ...

The field of particle physics is approaching a critical horizon defined by challenges including unprecedented data volumes and detector complexity. Upcoming ...

Almost a century after the legendary debate between Albert Einstein and Niels Bohr, a team led by Jian-Wei Pan from the University of Science and Technology of China has brought the famous ...
