I was thinking perhaps many supposed black holes have been found because there was a nearby star to give them away by their effects on that star/ Perhaps that might explain the binary theory?
From that article, it sounds like the really massive ones at the centre of galaxies might have been created in the Big Bang instead of collapsing stars. Which explains how the first stars were born pretty well, and the structure of galaxies too.
What are the other theories apart from black holes to explain the empirical evidence?
