hello, thank you so much for your answers :cool:

here I come with a question, maybe stupid. everyone knows about electrons, muons, taus. Is a heavier charged lepton impossible to exist? why does SM deal with three generation of particles (each consisting in a charged lepton, a neutrino plus two quarks), and not more? thanks everyone.

Hi all :approve: I'd like to know your opinion about this: how to evaluate if an autogravitating body is stable? I'd like to know which analytic consideration should we do. Example: experience tells us that a sphere is pretty stable. But... something else? A torus is stable? Or should it evolve...
