      > the vacuum (if it is a vacuum)

      Here is a five-hour video essay explaining that we actually live inside a superconductor: https://youtu.be/DkH1citHtgs

      That is, the reason the weak nuclear force has limited range in our "vacuum" seems identical to the reason the electromagnetic force has limited range in an electric superconductor. Therefore we live in a weak nuclear superconductor. Whatever that means.

      (Furthermore and even weirder, the electromagnetic force is a shadow of the weak nuclear force, the one-dimensional projection of it that retains an unlimited range even inside the superconductor, which happens because of reasons)

    Is there a math edition?
