Welcome! Here you will find information about the latest, relativistic version of the transactional interpretation of quantum mechanics, 'RTI', blog posts, and an opportunity for informal discussion. The transactional interpretation (TI) is a new way of understanding what's behind the formalism of quantum physics. My CV is available here. The 2nd edition of my book … Continue reading Welcome!
In a previous post, I presented a Comment for an online forum on a paper by Gruber, Block and Montemayor, 2022 that discusses the alleged conflict between "physical time" and the human experience of time. Since that time, an additional target paper was added for the discussion, and I've made my comment shorter and more concise. … Continue reading Updated Comment: “Physical Time as Human Time”
In the relativistic transactional picture (RTI), spacetime is an emergent construct. It emerges from specific interactions at the quantum level (i.e., transactions). This process creates a metrical structure; thus, RTI allows the harmonious integration of quantum theory and general relativity, two theoretical domains generally thought to be in conflict. I've just completed a collaboration with … Continue reading Transactions Complete Entropic Gravity
I was invited by the above authors to comment on their paper, recently published in Frontiers in Psychology (doi: 10.3389/fpsyg.2022.718505). The authors deal with an issue generally viewed as problematic: reconciling the human experience of time with physical theories addressing time. The idea is that several of us will participate in a published panel discussion … Continue reading Comment on “Physical Time Within Human Time” (Gruber, Block and Montemayor, 2022)
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
I've been enjoying my stay this semester at University of Pittsburgh's Center for Philosophy of Science. Here's the video of my March 15 talk: https://youtu.be/YNIdSu-HqFo?t=173
I'll be presenting a talk at the Center for Philosophy of Science at the University of Pittsburgh on March 15 (2022). In this talk I'll be discussing how the Direct-Action Theory of Fields (also known as the 'Absorber Theory' can resolve numerous problems in physics, some of them seemingly unrelated. The core of this work … Continue reading Talk at U Pitt on March 15
The standard theory of quantum mechanics has no intrinsic "collapse" or reduction. At most, it sometimes makes use of a "collapse postulate" that has no physical account in the theory itself and is applied to fill the explanatory gap between the usual unitary evolution (which, in general, does not yield a determinate result--that's the "Schrodinger's … Continue reading Is standard (unitary-only) quantum theory refuted?
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
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”
Jeffrey has been thinking about postmortem survival and wanted to discuss the implications of various physical theories for this question. https://www.youtube.com/watch?v=aME8UONGRFg
