I heard about USA actor Terrence Howard's 1x1=2 theory this morning and saw a video by Neil de Grasse Tyson respectfully disagreeing with it after devoting a lot of attention to it. Dr Tyson emphasized experiments verifying objective reality but both quantum mechanics and multiverse-originator Hugh Everett say there's no such thing as objective reality.
Regarding QM - if quantum superposition is taken to its logical extreme, everything in the universe would affect everything else. Regarding Everett - his idea of the universal wavefunction says the observed and observer are all mixed together. This means an experimenter's consciousness can never avoid influencing (technically, biasing) an experiment.
Dr Tyson would be very aware of these QM/Everett things but he seems to be unconsciously reverting to a classical view in which objective reality exists in all space-time, and not just in the limited perceptions of humans or animals. Our restricted senses (and concepts) might view a quantum superposition where everything, including consciousness, fills all space and time as a subatomic particle being in more than one place at once. To finish, I was strongly attracted to the statement 1x1=2. This is because my own theory of everything - they're very common, aren't they? - gives 1+1 never equals 2 a central importance. (Lucy was correct when she stated in the self-titled movie that 1+1 has never equaled 2.)
