Virtual partcle (Wikipedia):
"The term is somewhat loose and vaguely defined, in that it refers to the view that the world is made up of 'real particles'. It is not. 'Real particles' are better understood to be excitations of the underlying quantum fields. Virtual particles are also excitations of the underlying fields, but are 'temporary' in the sense that they appear in calculations of interactions, but never as asymptotic states or indices to the scattering matrix. The accuracy and use of virtual particles in calculations is firmly established, but as they cannot be detected in experiments, deciding how to precisely describe them is a topic of debate." They are just as 'real' in Ruth Kastner's Transactional QM. https://www.informationphilosopher.com/solutions/scientists/kastner/ Physics = Math + Witchcraft @philipthrift -- You received this message because you are subscribed to the Google Groups "Everything List" group.
