The discussion revolves around the relationship between the frequency of virtual particles and Quantum Brownian Motion, particularly questioning whether these frequencies correspond to the random paths taken by nuclei. The scope includes theoretical aspects of quantum mechanics and the nature of virtual particles.
Participants express differing views on the reality and significance of virtual particles, with some asserting their existence and others denying it. The discussion remains unresolved regarding the connection between virtual particle frequencies and Quantum Brownian Motion.
There are limitations in the discussion regarding the definitions of virtual particles and the assumptions underlying their proposed frequencies. The nature of Quantum Brownian Motion and its causes is also not fully resolved.
This discussion may be of interest to those exploring quantum mechanics, particularly the concepts of virtual particles and Quantum Brownian Motion.
How often they pop in/out of existence.mfb said:What do you mean with "frequency of virtual particles"? Virtual particles are a tool in calculations, they are not real.
As I said, that is not a meaningful question.How often they pop in/out of existence.
So if it is not about virtual particles, then what is the cause of Quantum Brownian Motion?mfb said:As I said, that is not a meaningful question.
You cannot say "see! there was a virtual particle". They are a mathematical tool in quantum field theory.
mfb said:Interactions with other particles, described with quantum theory.

Everything around the particle you consider (that is an answer to both questions).I mean the what is the cause of the "nucleus random path"? And who are those particles?
Their mass must be very very small (smaller than relativistic mass of photon).mfb said:Everything around the particle you consider (that is an answer to both questions).
