SUMMARY

The discussion centers on the complementarity principle in quantum mechanics, specifically addressing Alain Aspect's conjecture regarding particle properties. It asserts that particles express one attribute at a time, influenced by the measurement device, and posits that particles may have predetermined properties prior to measurement. The conversation highlights the Bell experiment as a thought experiment, emphasizing the lack of definitive data supporting the hypothesis that particles do not possess properties until measured. Additionally, the double-slit experiment is referenced as evidence suggesting predetermined properties exist.

I just came up with this idea, and wanted to run it by some people who know more than me. Are there any data that I can find that show I'm wrong about this?

Particles only express one attribute at a time, but may have many different attributes, and which one is expressed depends on the nature of the device measuring the expression. This would allow a Bell experiment to measure one particle with up spin and anotother with down spin 100% of the time, while also measuring the same two particles as up and left/right. Alain Aspect conjectures that this indicates that each particle has no determined properties until it is measured. I contend that the particle that was measured being up may have also been spinning left until it was measured, and the particle measured right was also spinning down, leading to a system in which particles do have real properties from their creation, and the reason different properties have no apparent correlation isn't that they don't exist until measured, but that the act of measuring a property caused the particle to express what is being measured. This has nothing to do with Observers per se, but comes about through any interaction between two particles. This would also mean that the real reason we don't see quantum uncertainty activity in large systems is that, in a sense, the other particles in the system are observers.

Thanks, An Amateur Physicist

Unfortunately, there is not much data available that directly addresses your hypothesis. It is important to note, however, that the Bell experiment is a thought experiment and not an actual experiment, so it is difficult to draw firm conclusions about the behavior of particles from it. That said, many physicists believe that Alain Aspect's conjecture is the most likely explanation for the results of the Bell experiment. It is also worth noting that there have been experiments which suggest that particles do have predetermined properties prior to measurement. For example, the double-slit experiment has shown that particles can interfere with one another even when they are not being measured. This suggests that particles do possess some kind of predetermined properties, although the exact nature of these properties remains unknown.
