So where is the logical contradiction in 1, or 2 ?
My dear Mr Hamilton, methinks you are stranded;
You see, the momentum wavefunction contains the probabilities of the momentum of the particle whilst a spread-out position wavefunction contains the localized momentum w/f, and vice versa. Since prior to our measurement neither position nor momentum have actual physical reality, it is clear that solely thanks to our awareness/ conscious decision we can actualize to a greater precision either the position or the momentum. Of course we have to keep in mind that over here (ie in the double slit experiment) we merely describe the way a mathematical entity is changing: we don’t deal with a real wave that hits the screen but with a set of numbers. And, although we calculate how a particle arrived at a certain location, we still ignore what a particle is. Therefore, your (1) does not hold.
Penrose demonstrated how the quantum experiments show that, whenever the classically physical states of the quantum particle are not measured continuously, they revert to be quantum probability waves till the occurring of another measurement. Therefore, when we conduct measurements (for example) of the electron standing waves (that fit around the circumference of the nucleus in a way that the starting point of the wave of the orbit of the electron meets the last point of this exact orbit at the same amplitude and at the same point as the beginning point) we are obliged to use the wavefunction -which, according to Born, is not an actual wave but a set of numbers indicating to a probability wave. When the amplitude of the wavefunction for a specific position at a given time is squared, its value represents the probability that a particle will be located by a process of measurement at that time in that position.
Of course the squared w/f gives merely the probability that, during a measurement (mind you: measurement without some kind of awareness in the context of a specific spacetime is impossible, and methinks this is exactly Taoman’s point; if I am wrong, he will have me corrected) we will establish the presence of a particle. The point is that the particle whose presence we registered thanks to our measurement, does not exist prior to the measurement interaction. Therefore, your (2) does not hold.
Regarding your thesis about the time, maybe we could agree with Penrose (Emperors New Mind, Oxford Un. Press paperback, 1999) that, “…since a w/f predicts the time evolution of the state of a quantum system, whenever we conduct a measurement we have to discard the quantum state we were evolving and use it merely in order to compute various probabilities that the state will jump to one or another of a set of new possible states”. This means that, at least according to Penrose, the transition of the quantum system to the states we are measuring is abrupt and non-deterministic, and this is proven from our inability to predict which exact probability will be manifested out of the (non-manifested mind-only field of probabilities, empty, sunya) continuous development of the wavefunction. This exact string of thoughts forced Rosenblum, Bruce and Kuttner to state in 2006 that the particle “…was not there before you found it there. Your happening to find it there caused it to be there”.
All the above are analyzed in detail by Smetham -I still cannot find a paper or a book that debunks the core theses of his “Dancing in Emptiness”
