If Dragonfly 44 has an Abell 520 history, (at the right side) then we may assume that Dragonfly 44 is the remnant of the central clumping dark matter in the form of black holes acting as the centers of the 100 large Globular clusters. Black holes are complex quantum knots of all different sizes (even ball lightning) and the same as Dark matter.
According to Quantum FFF Theory’s New physics.
