Initial fluctuations in the matter density of the early universe led to the formation of galaxies, but these fluctuations must have been small or they would have imprinted themselves on the microwave background.

After a few billion years, these early, smaller galaxies became the building blocks of the larger galaxies that came to dominate the universe, scientists believed.

Other theories, like mergers of smaller black holes, remain viable, and researchers aren't quite sure yet how many black holes there really are in the early universe.

However, in the smaller, early universe, some growing black holes and nearby stars might have merged before the heavens were stretched out leaving extremely large MBHs in small galaxies.46

The idea goes like this: Early in the universe's history, large galaxies grew out of collisions and mergers of smaller galaxies.
