Why? The new Physics of Q-FFF Theory says, by the Merging mini Starspot black holes s into one large black hole, able to produce plasma jets all directions around as observed (photo) instead of into one line.
700 Vanishing Stars found in the last 20 years. Q-FFF Model says; Due to the growing by merging of internal new physics Starspot Black Holes repelling all Baryon Star plasma away by multiple plasma jets. Due to the absence of two aligned Herbig Haro Anchor Black Holes, which is assumed to be the rigin of standard jets ejected by new stars created between two equal size Herbig Haro black holes
Three images of vanishing stars, 1: Multiple gamma ray events in the Milky way, by merger starspots 2: A star with 2 large new physics (Q-FFF) Black Hole Starspots, 3: Explosion of a vanishing star by the ejection of multiple plasma Jets.
Below; The dual plasma jets repulsed by a Dual Anchor Black Hole based Herbig Haro star.
Below: the White Hole in the middle of each Herbig Haro dual Black Hole system, is a deluded vacuum process for plasma concentration forming a star and later central Black Hole in the galaxy.
How did black holes get so early in the universe? due to the explosion of the former Big Crunch Dark matter black hole into smaller pieces. only 6 of them we are still able to see at only one side of our observable bubble (below yellow sphere) Why? because all the other early black holes are futher away from us and out of sight
