[math-fun] What's New in Timetravel News?
According to my newsfeed, a mathematical proof of a grandfather-nonparadox theorem has been achieved in almost perfect timing with the release of Christopher Nolan's new movie "Tenet". Briefly perusing the paper, it seemed to be above my paygrade. Their idea about time traveling "agents" confused me--are the "agents" supposed to be subatomic particles or can they be equipped with extra, dangerous technology? Seeking an answer to this question, I decided to travel back in spacetime (Elsewhere in the Buddhaverse), Cordoba, Argentina, 1992, where A Plenary Lecture on closed timelike curves (CTCs) was given by Nobel Prize winner Kip S. Thorne: https://s3.cern.ch/inspire-prod-files-9/9e243ddb6420681ac2362781c9754c04 This article I could almost understand, and the conclusion in section four seems to me, most reasonable. A feature of the Feynman diagrams is that they contain CTC's at a subatomic scale. Since a theory of quantum gravity is lacking, we don't know if quantum CTC's could ever extrapolate to macroscopic scales. Later in the future, why should we be surprised if known quantum behaviors reach a semiclassical or classical cut-off, beyond which extrapolation is nonsense? The other totally stupid idea I've heard is that, due to tunneling solutions of Schroedinger's equation, people might someday be able to walk through walls. I guess I'll change my position if such a measurement is ever made during my lifetime. As for "Tenet", I risked a large theatre with ten or so other people, and liked the movie much more than interstellar (a movie that I couldn't understand in the least). A sequel could turn out even better. Terms are already defined, and we have a few questions left to wonder about. Who is this woman being compared to Oppenhiemer? What type of mechanisms exist for enacting an uncertainty principle between the orthogonal dimensions of protagonist and antagonist? All the facts of the movie point strongly to the interpretation that "the protagonist" should not be trusted! When venturing to public spaces, be advised of inherent COVID danger in closed rooms. --Brad
Hi Éric, Thanks for this piece of information, I assume you are referring to this magic square: https://en.m.wikipedia.org/wiki/Sator_Square My feeling is that a true protagonist is more likely to be working outdoors, on behalf of the “cherry tomatoes”. In a worst case scenario, I doubt that we are going to reach circumstances where we could travel back in time for a harvest season. —Brad

... watch out, Brad, as it reads backwards DIVO COVID (God) if we follow the Sator Arepo TENET path!
