In physics, normally a critical information solves many seemingly unrelated problems at the same time. I think this is the case with the information that neutrinos are magnetic monopoles of tachyonic nature in the universe does. It fulfills the symmetry of Maxwell's equation first. The question of where are all the magnetic monopoles in the universe is answered. It solves why and how light propagates in the absolute vacuum because waves need a medium to propagate. After all, it also turned out that neutrinos are the key players in the mystery of quantum mechanical uncertainty in the universe as well. The magnetic monopole neutrinos of tachyonic nature is all it takes. The solid experimental proof is in the measurement of the neutron's magnetic monopole charge by experiment.
It seems that the inertial mass of the electron can be explained by tachyonic magnetic monopole neutrinos.
What would be the defect of this investigative conclusion other than it doesn't explain the mass of the proton which has never been found to decay?
Neutrinos and electrons are in the same category of elementary particles. One is magnetic monopole and the other is electric monopole. One has real mass and the other has imaginary "numbered" mass. They are both abundant about the same scale of numbers in the universe.
The main problem is there doesn't seem to be enough opposite magnetic monopole as many as the north pole type in this universe contrary to positive and negative electric charge of electrons and protons. What is going on?
If proton doesn't decay at all, how Big Bang theory can be a correct theory? Deficiency of antimatter in the universe is not a glitch of Big Bang theory, it is a fundamental stumbling block.
It shakes the root principle of Big Bang theory.
The matter-antimatter universe must have been created at the same time of the real big bang and they went out separate ways in time. But then it is not the big bang theory every body knows what it is.
