The intial weak force interactions conditioned the neutrinos to have a bias in their spin state switching. Neutrinos continually switch from -1, 0, and +1...the bias is towards 0 and +1. Matter accumualtes the bias, and the flux in empty positive space is such that the neutrino distribution is shifted towards anti-gravity characteristics. Neutrinos are single gravity particles...the force interactions occur on strong force boundary...this induces weak force compensations. There is a mediation between weak force origins imprinted in matter between the weak force origin and the strong force boundary. That is why free protons and neutrons are so unstable, unlike free electrons. The electrons are used to deal with this flux by maintaining probability shells around the nucleus.
