Okay, so I've just begun to have a grasp on the concepts of quantum chromodynamics. And what amazes me is that quarks never actually exist on their own as a single particle because of the strong interaction between them. I've read that when you try to pull apart a pair of quarks that is bonded together by a gluon, they act like a rubber band, and when they got into this "pulled limit", instead of breaking them apart, another pair of quarks is produced, and the old pair of quarks remain confined. 1. I would appreciate if someone could explain and discuss more on this awesome process/phenomena. I just think this is pretty interesting. 2. Do physicists work on trying to get around this quark confinement, in an attempt to find a way to break them apart? 3. So if quarks remain confined as composite particles (hadrons), how did particle physicists experimentally observed, discovered, and identified each type of quarks (up, down, top, bottom, strange, and charm) as a single particle? It's like they "poked" into a hadron and observed that there are those quarks inside, and identified there different types. Or something like that. Thank you very in advance. I apologize if I said anything wrong in the post, being a beginner.
