Just from general ideas gained over time I am under the impression that structure in our universe started with slight anisotropy in the CMBR. That slight fluctuation is gradually compounded and leads to structure, i.e. galaxy formation. Building on that idea I am concluding that black holes form inside galaxies and a balance is reached in the distribution of mass in the galaxy so the central mass usually represents about 1% or 2%, perhaps regulated by the jets near the center and accretion at the outer reaches? Having asked this question a year or so on a forum about whether galaxies form from the black hole or if the black hole forms inside the galaxy I have found that both views were supported. Is there now any prevailing view on this matter?
