Mysterious accelerating object near the center of the Milky Way seems to be the ZPE propelled super nova black hole assumed to produce a growing plasma tail pointing to the MW center and coming to rest between other equal massive Halo electric dark matter black holes. According to Quantum FFF theory.
ZPE accelerated Dark Matter Black Holes of all scales by Quantum FFF Theory. Ball Lightnings tacking into the wind direction seem to be comparable Super Nova Black holes tacking away from the MW nucleus.
