Understanding Retrocausality - Can a Message Be Sent to the Past?
- Boundary Institute, P.O. Box 10336, San Jose, CA 95157 (United States)
We examine why exactly it is that a message cannot be sent into the past and received there using quantum physics, yet certain anomalous correlations can make it appear just that way. To accomplish this, we must first explore more deeply the usual concepts of superposition, entanglement, measurement, locality, and causality. From these reinterpreted concepts, and through analyses of the usual forward EPR experimental arrangement and a time-symmetrical backward version, we can better understand the fundamental inadequacy of the idea of 'causality' (both forward and backward). We also discuss possible explanations for apparent retrocausal anomalies such as those of the recent experiments by psychologist Daryl Bem.
