International researchers, including UC San Diego physicists, conducted a "Cosmic Bell" test with polarization-entangled photons to further close the "freedom-of-choice" or "free will" loophole. The experiment tests Bell's inequality, and results push back to at least 7.8 billion years ago the most recent time by which any causal influences from alternative, non-quantum mechanisms could have exploited the loophole.
