George servinka says near the end of the biggest ideas in the universe, number 15, on gauge theory, that symmetry is both preserved and spontaneously broken. The mexican hat shows potential energy as non zeroa equal zero, and then it rolls down to zero potential energy at many points. Gauge in variance seems to prevent the particle exitations of these new fields you 're inventing from having mass. It predicts very strongly that the particles should be massless. And so it seems that if you have a gauge theory, you have massless particles. But we know that the strong interactions, or we thought we knew, strong ineractions, an weakiner actions, do not
Welcome to the November 2021 Ask Me Anything episode of Mindscape! These monthly excursions are funded by Patreon supporters (who are also the ones asking the questions). I take the large number of questions asked by Patreons, whittle them down to a more manageable size — based primarily on whether I have anything interesting to say about them, not whether the questions themselves are good — and sometimes group them together if they are about a similar topic. Enjoy!
