Is wave-particle duality a result of the relativity theory?

Click For Summary

Discussion Overview

The discussion revolves around the relationship between wave-particle duality and relativity theory, exploring whether wave-particle duality is a consequence of relativistic effects. Participants examine the implications of high-speed collisions and the nature of quantum objects, questioning the validity of wave-particle duality in modern quantum physics.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Exploratory

Main Points Raised

  • Some participants speculate that wave-particle duality may arise from relativity theory, particularly through concepts like length contraction and dimensionality reduction.
  • Others argue that wave-particle duality is an outdated concept from 'old quantum theory' and assert that modern quantum physics does not support this duality.
  • A participant suggests that measuring high-speed quantum objects resembles collision experiments, which may reveal the role of relativity in understanding quantum behavior.
  • There is a contention about whether quantum theory (QT) is a physical theory or merely a mathematical framework, with some asserting that relativity underlies the real physics of quantum phenomena.
  • Some participants note that quantum field theory integrates special relativity with quantum mechanics, indicating a more accurate framework for understanding quantum objects.
  • One participant emphasizes the importance of symmetries in space-time models and discusses the challenges of formulating a quantum theory of gravitation.

Areas of Agreement / Disagreement

Participants express multiple competing views regarding the nature of wave-particle duality and its relation to relativity. There is no consensus on whether wave-particle duality is a valid concept in modern physics or how it relates to relativity.

Contextual Notes

Participants reference various interpretations of quantum mechanics and relativity, highlighting the complexity of integrating these theories. There are unresolved questions regarding the implications of quantum field theory and the nature of quantum objects.

Have thought about this for sometime but couldn't get deeper.
I have speculated that wave-particle duality is a direct result of the relativity theory. Especially it could arise from the factor of length contraction (dimensionality reduction). So far, the particle reality is based on various high speed collision experiments. When high speed waves collide into each other or something, the action may reveal extra hidden small dimension or result in diminishing of some dimensions.
Hope someone if have the same idea can work out a math for this...

Wave-particle duality is an outadeted concept that belongs to so called 'old quantum theory' which died around 1924-1926. There is no duality in modern quantum physics. Use 'search' button, there have been plenty discussions about that issue.

Thanks Weridoguy for the reply. I guess people have no further understanding other than to accept that these are quantum objects describing by quantum theory. Quote "These quantum objects exhibit wave-like properties if you measure for wave like properties and they exhibit particle-like properties if you measure for particle-like properties, but neither of those facts makes them a wave or a particle, they are just quantum objects."
Here the thing is about "measure". Measuring a high-speed quantum objects looks very much like to do a collision experiment. That's why I am thinking of Relativity's role in quantum objects. And intend to believe a quantum object is only a "quantum wave", not a quantum particle.

You're just playing games with words. A quantum object is a quantum object.

Where are you quoting this from? You need to give specific references.

That's one way of measuring, yes. But it's certainly not the only one.

Quantum field theory combines special relativity with quantum mechanics.

Sorry, quoted from one of Phinds' post.
Can people believe that QT is not a physical theory rather than a mathematical frame? The real physics here lying behind is Relativity?

I don't understand what you think the difference is between a "physical theory" and a "mathematical frame". Both quantum mechanics and relativity make predictions that can be compared with experiments.
 
There is nonrelativistic quantum mechanics and there is relativistic quantum mechanics. The latter is more accurate and quantum field theory is fully relativistic. The categories you ask about don't exist.

Relativity provides the space-time model that is most succuessful in formulating all of physics. The most comprehensive space-time model we have today is general relativity, closely related with gravity, but there's a problem with a fully satisfactorial quantum theoretical formulation of gravitation. Fortunately gravitation is so weak that it can be neglected in many circumstances.

Thus one describes space-time by special relativity (Einstein-Minkowski space) and matter and its interactions with relativistic quantum field theory. This makes up the Standard Model of elementary particles physics, which describes all known matter and the electromagnetic, strong, and weak interactions (where the electromagnetic and the weak interaction is combined into the electroweak interaction). The first step in systematically building this theory is a careful analysis of the symmetries of the space-time model, leading to the notion of mass and spin as the basic properties of any quantum system. The gauge symmetries underlying the description of the interactions further lead to several conserved charges (electric charge, weak isospin, and color charges).

It may well be that with a complete theory of everything, which must include (at least!) gravity, that there's no more separate space-time concept left but everything is in some way combined to one quantum-theoretical framework, but that's speculation since there's not yet any really convincing answer to this most challenging enigma of contemporary physics.
