  • Strong interaction is really designed as a baryonic thing, leptons have no color charge (which is another way to say that they transform as SU(3) singlets). Leptons do not interact with gluons.
    Not at tree-level anyway. See for example this list of vertices.

    At loop levels, it’s possible to imagine an electron decaying into neutrino+W, then W into two quarks who can then interact with gluons, but as it’s down a couple of orders in perturbation theory so probably much too weak to hold a nucleus together. Not an expert in particle physics so I do not know with certainty whether a couple-of-loops interaction can have a measurable effect.






  • The scifi “dimension” is as meaningless as “plane of existence”

    Does not sound too meaningless to me, but I’m used to calling that a universe 😁

    think about the sentence “the universe is a part of our dimension”

    I’m trying ahah. But if you call the universe a dimension, which subpart of it do you call a universe? The observable universe maybe? I mean it makes sense to say that the observable universe is part of our universe. Still sounds strange the way it is presented by OP.

    You cannot follow Lemmy users, only communities. AFAIU, Lemmy just does not do anything with that request.

    To share my experience : my Friendica account is set up to automatically boost anything @Liwott produces, and it does so as soon as this instance is aware of the Lemmy posting, but that does not always happen automatically. Sometimes I have to search my Lemmy post on Friendica, and only then it is boosted. Note that I do follow my Lemmy account from here
