In episode 4 of Quantum Consciousness, Justin Riddle discusses prevalent interpretations or "theories" of quantum mechanics. First is the many worlds hypothesis that claims we live in a multiverse. The problem is there is no point of making choices when all possible realities occur. There is no collapse of the wave function and superpositions are different universes. Alternatively, when systems interacts with each other they might collapse the wave function by virtue of their interaction. But Einstein question: would the moon cease to exist if we did not look at it? There may need to be an explanation for superposition without any external influence; furthermore, this is quite a chaotic process and the universe is full of order. Third, the self-collapse of the wave function was proposed by Roger Penrose to arise once a superposition evolves into sufficient complexity. This form of collapse may be especially poised to produce an increase in order. Roger Penrose and Stuart Hameroff suggest this form of collapse is the substrate of proto-consciousness and might be selected for and 'orchestrated' in biological systems. Finally, the spaceless/timeless domain of entanglement has been suggested to serve a "holomovement" of the universe by David Bohm and Henry Stapp to serve as a collective feedback loop. Carl Jung and Wolfgang Pauli speculated that if entanglement relationships found their way into the physical world they might be perceived as synchronicity. We sure go off the deep end with this one!
