Factorization in retrocausality: a response to O. Costa de Beauregard

  • C. I. J. M. Stuart


Costa de Beauregard's reformulation of joint probability, in connection with retrocausality, reveals a mathematical paradox independent of time-reversal. That paradox is intrinsic to Bell's theorem and has a physical manifestation in the Orsay experiments.

Key words

retrocausality causality and independence Bell's theorem Orsay experiments
