In summary, while it is possible that particles may have predetermined properties that are affected by measurement, the current evidence suggests that the most likely explanation for the results of the Bell experiment is that particles have no determined properties until they are measured.

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.
 

FAQ: On the complementarity principle

What is the complementarity principle?

The complementarity principle is a concept in physics that states that certain properties of particles or systems cannot be simultaneously measured or known with precision. This is because the act of measuring one property necessarily affects the other, making it impossible to have complete knowledge of both at the same time.

Who first proposed the complementarity principle?

The complementarity principle was first proposed by Danish physicist Niels Bohr in the early 20th century. He developed this principle as part of his work on quantum mechanics and the understanding of the behavior of particles at the atomic level.

How does the complementarity principle relate to the uncertainty principle?

The complementarity principle and the uncertainty principle are closely related. The uncertainty principle states that the more precisely we know the position of a particle, the less we know about its momentum, and vice versa. This is because the act of measuring one affects the other, just like in the complementarity principle.

What are some practical applications of the complementarity principle?

The complementarity principle has been applied in various fields, such as quantum cryptography, where the principle of complementarity is used to encode information in a way that cannot be intercepted without changing the information. It is also used in quantum computing and the development of new technologies in the field of quantum mechanics.

Is the complementarity principle universally accepted?

The complementarity principle is a fundamental principle in quantum mechanics and is widely accepted by the scientific community. However, there are ongoing debates and research about its exact implications and interpretations, and some scientists continue to explore alternative explanations for the observed phenomena.
