    I know it flips everything scientists thought about the formation of galaxies on its head, but it makes sense.

    The article is paywalled so i cant read it. Im guessing that the black holes draw matter, stars and such, to them and the more stuff thats drawn in the more stable the system gets and a galaxy grows out of it.

    Wicked cool shit

    Edit: i hadn’t even thought of this, its even cooler imo

    If (primordial blackholes) do exist, they would have formed in the first moments after the big bang, not from stars (stars didn’t exist yet) but simply because of the extreme pressure of the early universe.

        I edited in the reason the author gives, which is a lot cooler than my idea

          I just meant it made sense to me the black holes would come first because they give the rotation and shape.

            That’s a theory yeah. One of the reasons they think we might be in a black hole.
