There are two models for physics of comets, ‘Dirty Snowball’ and ‘Plasma Discharge’ models, in the first and famous model; a comet is an aggregate of ice and dust evaporating in the heat of the Sun. In the Plasma Discharge model, a comet could be a solid rock discharging as it plunger more deeply into the sun’s electric field. A proper comparison of the two models, however, will require attention to details, accentuating the contrast between two radically different perspectives. Systematic comparison can only highlight the contrasts in predictive ability.
