«in the deterministic collapse theory of 2016 [29] the nonlocal absolute phase constants of the wavepackets were taken as hidden variables (cf. [30]). Collapse occurs when two wavepackets spatially overlap and satisfy a mathematical criterion, which demands that their phase constants very nearly coincide. The wavepackets then collapse to the overlap volume. In a measurement this mimics the action of a point particle. The phase constants are pseudorandom numbers, in the sense of the deterministic chaos theory, and the Born rules are derived under the assumption that their distribution is uniform. »
« Physicists report that quantum behavior can be explained with classical physics for a single particle, but not for multiple particles as in quantum entanglement and related nonlocality phenomena ("spooky action at a distance" ["gruselige Action in einiger Entfernung" (german)],[344] according to Albert Einstein) »

Thus, classical mechanism deterministically explain ALL of quantum mechanics ! What still needs to be done is to unify those three local hidden variable theories and wouldn't that create the first theory of Everything ? A thing that quantum mechanics will never by design be able to do by being incompatible with general relativity.
Let's be clear, probabilities distributions (quantum mechanics) are a Nice map of the territory. But the map isn't the territory ans the territory IS superdeterministic like classical mechanics.
Also, I believe that local hidden variable theories are deeply underresearched because mainstream scientists have not updated their belief on them since 40 years... I guess too that many quantum scientists are afraid of dropping the Nice absurd Idea of free will...
