Q-FFF Theory however says: The anomalous Early brightness is assumed to be created by the influence of multiple "Starspot black holes" ( former comet nuclei) in the explosion process. HOWEVER until now, nobody seem to support such a starspot BH model, because BH should swallow all stars from the inside, which is not the case in Q-FFF Theory.
Because BHs repell all fermions in Q-FFF Theory, they eat the vacuum particle lattice as the base for gravity effects. see:
