2022-03-16: What If Charge is NOT Fundamental?

  • 09:07: The secrets of electric charge are actually hiding in the last, most obscure of the quantum forces - the weak force.

  • 04:33: ... as we'll see, the simple requirement that the weak force was mediated by massive particles ultimately unified the weak force with ...
  • 08:24: But the bosons of the weak force have to have mass.
  • 09:01: In order for the weak force bosons to have mass, we have to willingly break the symmetry that gave us them in the first place.
  • 10:43: So what if something similar is happening with the field that gives us the weak force?
