Forces (Fields) of Nature and Quantum Foundations

In summary: Some theories, like the Bohmian interpretation, have a lot of extra predictions that haven't been tested yet. Others, like the Copenhagen interpretation, are more conservative and only make predictions that are testable.

Is it possible for new forces or fields of nature to be connected to quantum foundations?

For example, new forces or fields that choose the decoherent histories or branches. Or generally actualize one of the decoherence branches?

Or should new forces or fields of nature be reserved for dynamics in atomic scale, like weak or strong forces or should be gauged fields.

So non gauged forces that *may* affect the quantum decohering dynamics (like the BM quantum potential) shouldn't be called fundamental forces (or fields) of nature?

What "new forces or fields of nature" are you talking about?

(like the BM quantum potential)

The BM quantum potential is not a "new force or field". It's just what you get when you rewrite the standard Schrodinger Equation in a different way.

The BM quantum potential is not a "new force or field". It's just what you get when you rewrite the standard Schrodinger Equation in a different way.

But if an experiment in future could distinguish a particular interpretation, let's say the BM quantum potential really exists and all quantum theory will be based on it plus explaining new future experiments (that other interpretations couldnt). Then one can consider the proven quantum potential as a force of nature? Or does a force or field of nature is related only to gauge symmetry?

It can't, since all interpretations of QM make the same predictions for all experimental results.

If you have something that makes different predictions, it's not an interpretation of QM, it's a different theory. Some people have proposed different theories that are inspired by the Bohmian interpretation, but those theories are not the same as the Bohmian interpretation itself.

Can anyone give a list of those different theories or give summary of each. Can it also predict all existing quantum experiments? The caveit is it just has more extra predictions, perhaps that can't be tested (or can)?

That's way beyond the scope of a single PF thread. You could search these forums to see if any such theories have been discussed, or you could spend time working your way through the physics literature.

This will depend on the theory.
 

1. What are the four fundamental forces of nature?

The four fundamental forces of nature are gravity, electromagnetism, strong nuclear force, and weak nuclear force. These forces govern the interactions between particles and objects in the universe.

2. How do these forces interact with matter?

Gravity is responsible for the attraction between massive objects, such as planets and stars. Electromagnetism is responsible for the interactions between charged particles, such as atoms and molecules. The strong nuclear force holds the nucleus of an atom together, while the weak nuclear force is involved in radioactive decay.

3. What is the role of quantum mechanics in understanding these forces?

Quantum mechanics is the branch of physics that describes the behavior of particles at the subatomic level. It is necessary to understand the behavior of particles and their interactions in order to fully understand the forces of nature.

4. How are these forces unified?

Scientists have been working towards a unified theory that explains all four fundamental forces in a single framework. The most promising theory is called the Grand Unified Theory (GUT), which attempts to unify the strong, weak, and electromagnetic forces. However, a complete unification of all four forces, including gravity, has not yet been achieved.

5. Are there any open questions or mysteries surrounding these forces?

Yes, there are still many unanswered questions and mysteries surrounding these forces. For example, the nature of dark matter and dark energy, which are thought to make up a large portion of the universe, is still not fully understood. Additionally, the search for a theory of quantum gravity, which would unify quantum mechanics and general relativity, is ongoing.
