``Definition of "Fundamental particles"'' by bchui on 2007-04-16 13:59:06
I have always been puzzled by the concept "fundamental particle".
What is the existing framework for the theory of "fundamental particle" and why it can explain quarks and electrons are "fundamental"? Does "quark confinement" means the energy barrier to break up a proton is higher than the energy can be priovided by the universe and so we say that "quark could not be more fundamental as it could possibly be detected by our universe"?
