Researchers have devised a proposal for the first conclusive experimental test of a phenomenon known as “Bells nonlocality.” This test is designed to reveal correlations that are stronger than any classical correlations, and do so between high-energy particles that do not consist of ordinary matter and light. These results are relevant to the so-called CP violation principle, which is used to explain the dominance of matter over antimatter.
