1: Another feature of the region that Crowe plans to examine further is the needle-like structures in the ionised hydrogen, which appear oriented chaotically in many directions/
2: For example, are more massive stars formed in the centre of the Milky Way, as opposed to the edges of its spiral arms?
Explanation for both features by the Q-FFF Theory:
1: Needle like structures are old jets or filaments inside old Herbig Haro star forming systems. The dual black holes are lost to larger ones to merge.
2: Indeed, the MW center is crowded by massive stars and black holes due to several merging series.
