Von Neumann proved that quantum theory is incompatible with the real existence of entities that possess either innate or contextual attributes that combine “in a reasonable way” to simulate measurement-dependent behavior. The qualifier “in a reasonable way” is the loophole evidenced by Bell that allowed Bohm’s ordinary reality model (based on the “non-reasonable” context-adaptable electrons) to exist.
Bell demonstrated the following important theorem: “Any model of reality whatsoever (ordinary or contextual) must be non-local”, that is must be connected by influences that do not respect the optical speed limit. In a local reality, influences cannot travel faster than light. Bell’s discovery of the necessary non-locality of deep reality is the most important achievement in reality research since the invention of quantum theory. Though motivated by quantum theory, Bell’s theorem has deeper roots. Von Neumann’s proof, for instance depends on the truth of quantum theory. Bell’s theorem does not. Though today’s quantum theory shows no sign of weakness, someday it may collapse. Bell’s theorem will survive its demise and impose non-locality on quantum theory’s successor. Because it makes contact with a general feature of reality itself, Bell’s theorem foretells the shape of all future physical theories.
So, irrespective of any physical theory, are we condemned to live in a super-luminal world? Does this entail unusual consequences such as, for example, time travel and reversed causality?
