Sagittarius A, the central Milky Way Black Hole: Multiple New Stars and Super Novas are observed around SgrA. The new physics Q-FFF Theory says: including Needle shaped Threads (being assumed Plasma trails left behind by: Travelling Tadpole Black Holes pushed by their Plasma tails.
Below: Even the travelling and trailing Tadpole Black Hole is pictured, as star streams, in this ancient artefact.
Below: Even dual Herbig Haro micro black holes seem to be able to travel pushed by dual self produced plasma tails.
How tubelike structures are made? by Splitting Herbig Haro Systems with splitting secondary black holes. see below:
