ORCs are two young spiral galaxies merged together created by 2x2 Galaxy Anchor Black Holes (Herbig Haro) perpendicular of each galaxy disc.
Why are fermions repelled from all black holes?
By the String propeller shape of each fermion.
see below:
Why each dual black hole based spiral galaxy creates a dual electron based Birkeland current caroussel globule, leaving a plasma dust disc with charged rings at its rim behind. below:Because the self created plasma tail forms a plasma bar repelling the two BHs drom each other. ( see below and above)
