According to Quantum FFF Theory, (new physics, Fermion repelling) Electric dark matter black holes with a microscopic sized nucleus, are produced by magnetic quantum interference (rigid string quantum knots). They produce plasma and water and are proliferated through stellar systems, as unstable Ball Lightning up to stable Comets and Sunspots (crashed Comets) As a consequence, crashed comets in the earth are responsible for the vulcanism and so called growing Earth by its growing compressed water core.
