Well, maybe. I learned of the existence of an alternate model for quantum behavior as I followed the story of a NASA test propulsion system that defies Newton’s Third Law. The idea named Bohmian mechanics is based on something called pilot-wave theory and has been around since the time of Louis de Broglie in the 1920’s. Ever since it has popped up occasionally, usually because some counter-intuitive results predicted by the standard Copenhagen model.
In 1932 John Von Neumann, the famous and formidable mathematician, “proved” that a result of Bohmian mechanics was impossible thus putting the theory to bed for, it turns out, 30 or so years at which time John Stewart Bell found errors in Von Neumann’s proof. A few more details to this story can be found here.
The title of this post expresses in some way a triviality. Any action in the present changes the course of events in the future – see every time-traveling science fiction movie. It’s just that we cannot know the magnitude of the resultant ripples in time. Yet, if the alternate theory of quantum behavior has been studied and deepened over that gap of more than 30 years might we not have other wonderful inventions like electromagnetic drive (if it works?)
