In classical physics, anything driven hard enough will eventually heat up, lose coherence, and settle into disorder. A new ...

For two centuries, students have learned that heat flows and engines work according to rigid limits that no machine can beat.

"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of physics.

If you drop a light object and a heavy object from a tower, which one reaches the ground first? As you may recall from high school physics, this is a trick question. Neglecting air resistance, they ...

Researchers at TU Wien have developed a one-dimensional “quantum wire” using a gas of ultracold atoms. In this system, both ...

A single atom as a movable slit: Researchers realize Einstein's thought experiment in original form, observing ...

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 ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

The pioneer of quantum computing talks about how Albert Einstein would have reacted to his experiments, the hype around the ...

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 ...

Take, for instance, quantum entanglement, which says that the state of one particle can be determined by examining the state ...
