Bell's theorem can be refuted by presenting a contextual model which correctly predicts measurement results with entangled photons or spin ½ particles. Contextual models can have properties which are ...

I know of scarcely anything so apt to impress the imagination as the wonderful form of cosmic order expressed by the ‘Law of Frequency of Error’,” the British polymath Francis Galton wrote in 1889.

We take for granted that an event in one part of the world cannot instantly affect what happens far away. This principle, which physicists call locality, was long regarded as a bedrock assumption ...

Quantum theory predicts the existence of so-called tripartite-entangled states, in which three quantum particles are related in a way that has no counterpart in classical physics. Theoretical ...

Sorry. Bell's theorem is a great topic of conversation in metaphysics to talk about over a drink with your physics and philosophy-inclined friends.

Astronomers propose an experiment that may close the last major loophole of Bell's inequality -- a 50-year-old theorem that, if violated by experiments, would mean that our universe is based not ...

The temporal order in which events occur can display quantum features. Quantum physics and general relativity are incredibly successful at describing physical phenomenon on tiny and massive scales ...

We are at a critical time and supporting climate journalism is more important than ever. Science News and our parent organization, the Society for Science, need your help to strengthen ...

His 1964 discovery, today known as the Bell Theorem, has been called the most profound scientific discovery made in the last half of the 20th century.
