The 2nd edition of my 2012 book The Transactional Interpretation of Quantum Mechanics (Cambridge University Press) will be coming out in June, 2022. Below is an excerpt from Chapter 8, on the emergence of spacetime in the transactional picture. Comments welcome! The Relativistic Transactional Interpretation and Spacetime EmergenceDownload

I recently gave a talk at an online conference presented by the University of Singapore's Center for Quantum Technologies. I discuss how the transactional picture can account for measurement and eliminate many of the problems of standard quantum theory. You can see the talk here: https://youtu.be/26ht9J-E-hg?t=170

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 →

It is with great excitement that I announce the creation of a new independent, non-profit academic research institute: The Quantum Institute. We are in the early stages of organization, but already moving ahead with some exciting research. Visit our new site to learn about what we're doing!

In this post, I address a question that pops up from time to time as a possible objection to the transactional picture. The scenario involves a very distant star that engages in a transaction with a person’s eye, so that they see the star as it existed billions of years ago. But suppose the star … Continue reading A Common Worry About TI and Why It’s Not a Problem →

The Afshar experiment (2005 ) is a lovely variant on the famous two-slit experiment. In this experiment, a grid is placed at the location of the dark fringes in what would be an interference pattern, but downstream from that location, the photon beam is subjected to a "which slit" measurement by way of lenses. However, … Continue reading Demystifying the Afshar Experiment →

A review from UK reader "Jehannum" was recently posted on the amazon.com page for my recent book Adventures in Quantumland: Exploring Our Unseen Reality (WSP, 2019). I reproduce it below: ***************** 5.0 out of 5 stars This book provides a revolutionary understanding of quantum physics. It's common to come out of a study of quantum … Continue reading Review of Adventures in Quantumland by “Jehannum” (amazon.com) →

(This is a preprint version of a technical paper. I'm making it available here in addition to the usual preprint servers. Questions/comments welcome.) Click here for the paper:  Light Tight Box Preprint Abstract: This paper discusses the nature of the boundary condition applying to the direct-action theory of fields, also known as the 'absorber' theory, … Continue reading Why the Quantum Absorber Condition is Not a Light-Tight Box →

It's always a pleasure to talk with Jeffrey Mishlove. In this interview we talked about the Transactional Interpretation and related ideas: https://youtu.be/E6NNWdVCQZU
