The Q-FFF model difference between Neutron star and Black hole Nebula production of supernovae explosions.
1: The Black Hole has gone and left the center by its new physics pushing tadpole plasma tail (Q-FFF model)
2: the Neutron star is stil observable at its original place.(see Hand of god)
3: the Knots/ Clumps related to tendrils or gas tails, are assumed to be self propelled former Starspot black holes or; Tadpoles (Q-FFF model) searching for an equal sized partner to form Herbig Haro star forming systems.
