Does dimensions have the same meaning in the Quantum world?

In summary, the conversation discusses the possibility of dimensions and time having a different meaning in the quantum world and how this could explain strange phenomena such as the spooky action at a distance. It also mentions the holographic principle and the potential for a quantum theory of gravity to shed light on the nature of space and time in the quantum world. However, as of now, there is no concrete evidence or understanding of how dimensions and time operate in the quantum realm.

Does dimensions and time have the same meaning in the Quantum world? Maybe that explain weird things as the spooky action at distance. What evidence are about the real existence of a 3 geometry dimensions world at quantum level? Maybe even time have a different meaning in the quantum world.

Even the spooky action at a distance keeps information constrained from propagating faster than the speed of light.
That's a distance per time constraint. So it would seem that x,y,z and time have application to QM.

But I wouldn't doubt that there is more to the story.
The first thing that comes to mind is the holographic principle: https://en.wikipedia.org/wiki/Holographic_principle
... suggesting that the x,y,z, time can be mapped to two spatial dimensions and time.

The holographic principle suggests that examining things in the frequency domain (a la Fourier Transforms) may reveal principles that are not evident in the x,y,z spatial domain.

Our best current theory of the quantum world is quantum field theory. This theory treats spacetime the same as in special relativity, so the strange effects that arise from quantum mechanics cannot be due to anything different about space or time in this theory.

Most physicists believe that we will eventually discover a quantum theory of gravity, which would, it is believed, allow us to treat space and time quantum mechanically. However, nobody has found such a theory yet, so we don't know what it will say about space or time, or whether anything different about space or time in this theory would be able to account for strange quantum effects.

1. What is the concept of "dimensions" in the Quantum world?

In the Quantum world, dimensions refer to the spatial and temporal coordinates that are necessary to describe the position and movement of a quantum particle or system. These dimensions are typically represented by mathematical terms such as length, width, height, and time.

2. Are dimensions in the Quantum world the same as the dimensions we experience in our everyday lives?

No, the dimensions in the Quantum world are not the same as the three dimensions (length, width, and height) we experience in our everyday lives. In fact, according to some theories, there may be up to 11 dimensions in the quantum realm that are not perceivable or understandable in our physical reality.

3. Does the concept of dimensions play a significant role in Quantum mechanics?

Yes, the concept of dimensions is crucial in understanding and predicting the behavior of quantum particles and systems. In Quantum mechanics, the dimensions of a system can affect its energy levels, wavefunction, and interactions with other particles.

4. Can dimensions in the Quantum world be measured or observed?

Some dimensions in the Quantum world, such as time, can be measured and observed. However, other dimensions, such as those beyond the three spatial dimensions, cannot be directly observed or measured. Instead, they are inferred through mathematical models and experiments.

5. How does the concept of dimensions in the Quantum world relate to the theory of relativity?

The concept of dimensions in the Quantum world is closely related to the theory of relativity. In fact, some theories, such as string theory, attempt to unify the principles of quantum mechanics and relativity by incorporating the concept of extra dimensions. These dimensions are believed to play a role in the fundamental forces of the universe and the behavior of particles at the subatomic level.
