  • A leader that is elected by their country, represents it.

    Well, that’s basically the propaganda. Says who? God? Physics? Neither. And, elect how? Some countries have proportional representation, which neither the US or Canada do.

    At the end of the day, a state is anything that has a monopoly on the use of force. Some allocate political power within themselves through elections (of many massively different kinds), while some do it other ways.

    You could say, “okay, elections have nothing to do with it, but we’re still responsible for what we let our governments do”, which covers the “it’s a collective responsibility” bit. And there’s a strong argument for that. But, by that measure pretty much everyone sucks everywhere, which you can take however you want.







  • Yeah, IIRC the force between nucleons is actually mediated by virtual pions, which are themselves composite particles. The direct nuclear force gets stronger with distance instead of weaker, which obviously doesn’t happen with whole atoms.

    It turns out that glueballs don’t come from “taking the quarks out” of regular matter but by some kind of direct excitation of the colour charge field – a thing I didn’t even know was a thing.

    Yep. It’s like if photons (which are the fundamental particles of electromagnetism) had a magnetic or electric charge themselves. That was a known property, but it wasn’t clear until now if it was enough to weave together into a larger particle like this.
