Quantum mechanics has always had a way of making even the sharpest minds stop and scratch their heads. In the everyday world, ...

Quantum entanglement, a bewildering phenomenon where particles become interconnected regardless of the distance separating ...

A new theory suggests that “time” might be the product of a universe that, long ago, decided to settle down into one ...

A survey of more than 1,000 physicists finds deep disagreements in what quantum theories mean in the real world ...

Hardy's paradox, created in 1992, hinted at a scenario haunting the edges of quantum physics. It presented a thought experiment where particles and their antiparticles might exist simultaneously ...

Physics Tweezers made of light could illuminate the quantum twin paradox A single ytterbium atom, cooled down to extreme temperatures and manipulated with laser beams, could reveal how gravity ...

Quantum physicists are notoriously divided when it comes to the correct interpretation of the equations that are used to describe quantum goings-on. But in the new thought experiment, no view of ...

A new hypothesis called the “quantum memory matrix” could solve long-standing physics questions, including the Black Hole Information Paradox and dark matter.

Even more ambitiously, Brukner and colleagues hope that thinking through the logic of quantum reference frames might yield new insights about quantum gravity — a research program that attempts to ...

Watch on (via Sabine Hossenfelder) Physicists have come up with a new experiment to test the quantum twin paradox using a pair of atoms in a superposition. It's an interesting idea because it could ...

Let me tell you about my book "Fields and Their Quanta: Making Sense of Quantum Foundations," published last year by Springer. It's technical, but I'll describe it in English.
