A Superluminal and Local-Causal Physical Ontology
Chapter 11. Causality in a New Double Slit Experiment and in Epr
In the meantime between the emergence of the Copenhagen interpretation and the recent EPR experiments, there have been many and varied schools of interpretation, including the hidden variables theory, but their relevance for the causal question is slightly reduced, in the face of some of the present-day double slit experiments (and EPR experiments) with their results. That is, many past experiments need not particularly be mentioned because the more recent ones highlight the issues better for our purpose of clarifying the extent of causality that we can conclude for QM. Let us grant our causal conclusion regarding the recent EPR experiments, and use it here in the discussion of a new version of the double slit experiment. As will be clear, the double slit- and EPR experiments and their interpretations can be seen in some way as related. This brings out some fundamental ontological errors in spacetime description based merely on mathematical imagination.
We study a recent double slit experiment and its suggested interpretation to solve the puzzle why the interference patterns disappear when we detect which slit each electron travels through, and why they create interference patterns when unobserved as wavicles. A team of scientists consisting of Stefano Frabboni (University of Modena and Reggio Emilia, and the CNR-Institute of Nanoscience, both in Modena, Italy), Gian Carlo Gazzadi (CNR-Institute of Nanoscience, Modena), and Giulio Pozzi (University of Bologna) used a transmission electron microscope for the modified version of the double slit experiment with a new “which-way” electron detector...
