"Prior to any measurement, the particle's position would just not exist!" Consider 3 questions: What is measurement? What is a particle? What is position? Does the Copenhagen Interpretation give precise answers to the 3 preceding questions? Does quantum information reduce to Fredkin-Wolfram information? Is Milgrom the Kepler of contemporary cosmology? Please google "kroupa milgrom", "mcgaugh milgrom", "sanders milgrom", "scarpa milgrom", and "witten milgrom".
According to Steven Weinberg, "It is a bad sign that those physicists today who are most comfortable with quantum mechanics do not agree with one another about what it all means."
