Could hidden dimensions help hidden variable theories ?

In summary, the conversation discusses the possibility of using hidden dimensions to support hidden variable theories that can also satisfy quantum mechanics. However, according to Bell's Theorem, any physical theory of local hidden variables cannot fully reproduce the predictions of quantum mechanics. The idea of non-locality is also brought up in relation to quantum entanglement and the discussion delves into the concept of multi-dimensional configuration space. However, the complexity of this topic makes it difficult to draw any conclusions.

Could hidden dimensions help "hidden variable theories"?

Could extra unobserved dimensions be of use in finding a hidden variable type theory that also satisfied Quantum Theory?

Thanks for any help!

Not unless those dimensions are somehow "global". According to Bell's Theorem:

No physical theory of local hidden variables can reproduce all of the predictions of quantum mechanics.

quantum entanglement seems to, in some ways, operate "outside" (or unaffected by) time-space.

Actually, QM is local in the multi-dimensional configuration space:

The argument that would force a hidden variable theory to be non-local if they existed does not, to the best of knowledge, change in any way if you allow for extra curled up spatial dimensions.

That is a very complex point. I would have to presume there is some kind of mapping from one to the other. Or perhaps a projection (from configuration space to our observable spacetime)? Anyway, I wouldn't have a clue as to where to begin on any of this side of things.

Although to be fair, I think non-local is usually taken to be in observable spacetime.
 

1. How do hidden dimensions relate to hidden variable theories?

Hidden dimensions are often used in theoretical physics to explain the existence of hidden variables, which are unobservable quantities that may influence the behavior of particles. These dimensions are proposed to be beyond the three dimensions of space and one dimension of time that we can perceive, and they may provide a framework for understanding how hidden variables can affect the behavior of particles.

2. Can hidden dimensions be detected or observed?

Currently, there is no experimental evidence or direct observation of hidden dimensions. They are purely theoretical constructs used in certain types of mathematical models to explain phenomena such as hidden variable theories. However, some scientists believe that future advancements in technology may allow us to detect or indirectly observe hidden dimensions.

3. How many hidden dimensions are there?

The number of hidden dimensions proposed in various theories varies. Some theories suggest there may be only one or two hidden dimensions, while others propose up to 10 or more. The number of hidden dimensions is still a subject of debate and further research is needed to determine their existence and properties.

4. Do hidden dimensions only exist in the field of physics?

While the concept of hidden dimensions is primarily discussed in the field of physics, it has also been explored in other fields such as mathematics and philosophy. Some theories suggest that hidden dimensions may also exist in the mind or consciousness, opening up new areas of study and debate.

5. How could hidden dimensions potentially impact our understanding of the universe?

If hidden dimensions do exist and can be detected or observed, it could greatly impact our understanding of the universe. It could potentially explain phenomena that are currently unexplainable, such as the behavior of particles at the quantum level. It could also provide insights into the nature of reality and the fundamental laws of the universe.
