SUMMARY

The discussion clarifies that the Casimir force and the strong nuclear force are fundamentally different phenomena. The Casimir force arises from a pressure difference in the quantum vacuum between two plates, while the strong nuclear force is not simply a lack of virtual particles but a distinct interaction between quarks. Misconceptions about virtual particles are addressed, emphasizing that they do not exist in a physical sense but are a conceptual tool in quantum mechanics. The relationship between the Casimir effect and Van der Waals forces is also explored, noting that they can be viewed as limits of a spectrum influenced by scale.

PREREQUISITES
  • Understanding of quantum mechanics concepts, particularly the Casimir effect.
  • Familiarity with the strong nuclear force and its role in particle physics.
  • Knowledge of virtual particles and their representation in Feynman diagrams.
  • Basic grasp of atomic interactions, including Van der Waals forces.
NEXT STEPS
  • Research the mathematical formulation of the Casimir effect using quantum field theory.
  • Study the strong nuclear force and its implications in quantum chromodynamics (QCD).
  • Examine the role of virtual particles in quantum mechanics and their representation in Feynman diagrams.
  • Explore the relationship between the Casimir effect and Van der Waals forces in greater detail.
USEFUL FOR

Physicists, students of quantum mechanics, and anyone interested in the fundamental forces of nature and their interactions.

I don't think "quantum foam" is a useful concept here.

but is the strong nuclear force the same thing?
No, it is a completely different thing. It has nothing to do with the Casimir force.
 
How so? Is it not simply a lack of virtual particle production between quarks?
 
And the quantum foam refers to the quantum chaos of virtual particle production in every point in space it couldn't be more relevant, if you're going to say I'm wrong all day long then help me understand how and provide some useful insight

Virtual particles do not exist.

The Casmir effect doesn't really have anything to do with the quantum vacuum either:

Its a myth - although a very common one even in professional literature.

Its one of a number of very common myths about QM:

As I said even though its a common misconception virtual particles do not exist - they are simply a name given to the pictorial representation of a Dyson series in a Feynman Diagram. You will find many threads discussing it so no need to go into it here.

What pushes the two plates together?

Did you read the link?

Thanks

You probably are familiar with the idea of atoms in a solid or liquid sharing valence electrons. This situation results in a lower energy than not sharing and keeps the structure together. As you bring the two plates closer together what do you imagine might be happening?

The distinction between Van der Waals forces and the Casimir effect has more to do with scale than anything else. They may be considered as two limits of a spectrum rather than as totally different effects. Relativistic retardation comes into play at greater distances.
