On the nature of neutrinos

Oh, the things that seem so simple after you've figured out the trick.

Photons are energy in space but not time.

Neutrinos are energy in time but not space.

Mass is a binding of space and time.

Thus, neither neutrinos nor photons have mass, and both travel at the speed of causality.  Photons do not change, because they have no time.  Neutrinos constantly change, because they are little else but time.

Neutrinos carry the weak force.  The weak force governs decay.  Spontaneous decay is entirely caused by time.  That's why they're called half lives - half of the number of particle p will decay in time t.

Time is a type of spin.  Anti- particles have opposite spin time.  Electric charge can be thought of as a spin in the same direction as time (arbitrarily plus), or the opposite direction (arbitrarily minus).  Thus, an anti-electron (positron), with negative time, to have a negative charge from its own perspective, must have a positive charge from ours.  Positive time, negative charge.  Negative time, positive charge.
