Despite the many published journals and articles on virtual particles, I now do not believe in them because of 1 person’s writings located here
at that site Arnold Neumaier, a theoretical physicist, explains principles to the layman (like me) about all the aspects of quantum mechanics. An excerpt of one of his writings on virtual particles reads thusly:
"the literature readily shows that the details of Feynman
diagrams strongly depend on the perturbation scheme used:
In light front calculations, one gets a completely different set of
diagrams than in the more traditional covariant form. And in
nonperturbative approaches such as lattice gauge theory or conformal
field theory, the predictions do not involve virtual particles at all.
How can anything be real if its existence depends on a particular way
of viewing the world? How can an experiment (verifying the Casimir
effect, say) can be said to prove the existence of virtual particles
if the same experiment can be explained by a method of calculation not
involving virtual particles at all?"
Now I have not read (or even understood) all of his writings, but 1 thing is nagging at me, what is magnetic attraction/repulsion if not the exchange of virtual particles as I had been led to believe?
