Physics experiments have changed the world irrevocably, altering our reality and enabling us to take gigantic leaps in technology. From ancient times to now, here's a look at some of the greatest ...

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 ...

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 ...

What makes something quantum? This question has kept a small but dedicated fraction of the world's population—most of them quantum physicists—up at night for decades. At very small scales, we know the ...

Reseachers observed sodium atoms breaking up into crystal particles that resemble tornado-like structures after entering a quantum state. Mukherjee et al, Nature, 2022 MIT researchers have now ...

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 ...

A series of quantum physics experiments and theoretical papers now suggest that heat can flow spontaneously from a cold ...
