There are bundles and bundles of information about particles to be found on the web and on this forum as well (many thanks to marlon). However, when you want to think about what's connecting these particles, what's between particles, things get rather blurry.. So, a couple of blurry questions: 1) It's physically possible to break an apple in half, and thus break the bounds between the two halves. It's physically possible to break a crystal in half, and thus have a deformed crystal with broken bounds. Now, when I look deeper, I notice that less and less people are talking about bounds, and more and more people talk about interactions. So, at the level of electrons floating around an atom, or at the level of atoms being made up out of quarks, is it still possible to imagine a physical operation that 'breaks' the bounds? Or will it always be one of two things: - the broken bits are unstable stuff and decay immediately - the broken bits find each other instantly and recombine In other words, is there some way to shield off one bit from the other? 2) Are such bounds physical things? I mean, can you give certain physical properties to what's between particles, and you can have different bounds with different properties thus making surrounding particles behave differently? You can describe particle physics by looking at the particles and describing their interactions according to certain rules - but is it also possible to make a dual description by looking at the bounds and describing the rules of the 'nodes' interconnecting them?
