Is There Really “Retrocausation” in Time-Symmetric Approaches to Quantum Mechanics?

This is a preprint version of this paper: AIP Conference Proceedings 1841, 020002 (2017) R. E. Kastner Abstract. Time-symmetric interpretations of quantum theory are often presented as featuring "retrocausal" effects in addition to the usual forward notion of causation. This paper examines the ontological implications of certain time- symmetric theories, and finds that no dynamical notion … Continue reading Is There Really “Retrocausation” in Time-Symmetric Approaches to Quantum Mechanics?

Paper with John Cramer on Absorption in TI

I recently co-authored a paper with Transactional Interpretation (TI) originator John G. Cramer, which derives the Born Rule (quantum probability rule) for radiative processes (emission and absorption) in a simple and transparent way, based on the Wheeler-Feynman-Davies'absorber' theory of radiation. It also shows that absorption is indeed perfectly well-defined in TI (contrary to skeptical claims … Continue reading Paper with John Cramer on Absorption in TI

On the Status of the Measurement Problem: Recalling the Relativistic Transactional Interpretation

In a nutshell, the measurement problem (MP) is this: given an interaction among quantum systems (such as an unstable atom, atoms comprising a Geiger Counter, atoms comprising a vial of gas, a cat, a friend of Wigner, etc.), which of those interactions constitutes ‘measurement,’ and why? During the past several decades, worries about the MP … Continue reading On the Status of the Measurement Problem: Recalling the Relativistic Transactional Interpretation

Life Creates Disequilibrium–But How?

As living creatures on this planet, we go through our daily lives dealing with the unexpected (whether welcome or unwelcome), the surprising, the awkward, the astonishing, the frustrating. Even if we are able to 'go on a vacation' to try to escape from all the chaos, we never really leave it behind. (Is there ever … Continue reading Life Creates Disequilibrium–But How?
