The Official version of Beta Decay bugs me.

With a half-life of 10 minutes, a neutron spontaneously decays to proton, electron, anti-neutrino plus kinetic energy plus W meson etc

n => p + e - v

Instead of spontaneous, I wish it were a neutron swimming through a sea of neutrinos until it gets so close

n +v => p + e

I prefer 2 things getting close enough to interact and turning into 2 different things than the official version where one thing spontaneously turns into 3 things.

Every book just says it is the Official Version. No book say why. Every book says W mesons are necessary for the whole process. No book says why.
