Black Holes

I learned that blackholes formed before galaxies. The new research presented today at the American Astronomical Society is preliminary. The new research is about 4 black holes that existed 1 to 2 billion years after the Big Bang. The mass of the black holes and galaxies were about the same. Astronomers used radio waves to look back to 1 to 2 billion years after the Big Bang. They found the four black holes and learned that it did form before the galaxies.
