The origin of Comet tail evaporation and plasma production, according to Quantum FFF Theory.

Not the radiation of the sun is origin of Comet 67P-CG plasma jets but several new physics micro dark matter black holes.
See: comet 67P-CG cross section with multiple craters supposed to be originated by ice funnel structures as the result of gravitating aligned micro Electric Dark matter black holes.
