The expelled Starspots of the Helix show us the propulsion effects of single starspot black holes (former crashed comets) forming so called Proplyds after star explosion., The Proplyds are single micro black holes propelled by self produced plasma tail.
Even Ball Lightnings on earth seem to be based om nuclear string knots or singularity black hole nuclei propelled like Proplyds. Conclusion: Ball Lightning, Proplyds, Tadpoles, Sunspots/ Starspots , even Comets have the same nucleus of interference based micro string knot black holes.
Helix former starspot micro black holes, with selfproduced plasma tails.
Neutron stars are massive fermion based. Starspot micro black holes have NO MASS !! What seems the reason for the different motion through the vacuum. According to Q-FFF Theory.
Even Ball Lightnings on earth seem to be based om nuclear string knots or singularity black hole nuclei propelled like Proplyds.
