So most of todays particle physics is bare nonsense or simply a mathematical fiction.
SInce todays particle physics is based more or less on - very expensive - experiments (CERN...), is there any other - more simple or more complex - theoretical explanation of what these folks can see and detect in their dayly practise (see below image which is real and no nonsense btw)? I mean, not that what we all had to learn in school or during academic education or can obtain from Wikipedia....?
