Forward Causation + Backward Causation = Zero Causation

Many researchers continue to discuss "retrocausal" approaches to quantum theory that involve a basic assumption that one can combine forward-directed causal flow and backward-directed causal flow "in spacetime." (My own proposal, RTI, has basic time symmetry but that is broken at the spacetime level, so it does not fall into this category.) In this post, … Continue reading Forward Causation + Backward Causation = Zero Causation

Why arguments against free will based on physics are hugely overrated

It seems that many scientists are eager to throw in the towel on free will. This somewhat technical article, published in Probing the Meaning of Quantum Mechanics: Superpositions, Dynamics, Semantics and Identity , Eds. D. Aerts et al, (2016) https://doi.org/10.1142/10185 , explains why that is a serious mistake. If anything, our best physical theories actually suggest … Continue reading Why arguments against free will based on physics are hugely overrated

No, different observers do not see “irreconcilable facts”: on “Wigner’s Friend”

A recent experiment in the lab, billed as a "Wigner's Friend" experiment, has been interpreted as a test of "local observer independence." The authors claim the experiment shows that observers must irreconcilably disagree on facts related to quantum measurements. The paper linked below (recently accepted in Foundations of Physics) shows that this is a misinterpretation … Continue reading No, different observers do not see “irreconcilable facts”: on “Wigner’s Friend”

Happy New Year! …and the latest on RTI

I'm celebrating the advent of 2021 with a post featuring the very latest theoretical developments supporting the Relativistic Transactional Interpretation (RTI): The Relativistic Transactional Interpretation and The Quantum Direct-Action Theory This material is based on Chapter 5 of the forthcoming 2nd Edition of my book The Transactional Interpretation of Quantum Mechanics: The Reality of Possibility … Continue reading Happy New Year! …and the latest on RTI
