Astronomers have observed supermassive black holes in the early universe — less than a billion years after the Big Bang — with masses far larger than standard growth theories would predict. These observations challenge conventional astrophysics because there appears to have been insufficient time for black holes to grow so large using only traditional processes such as stellar collapse followed by steady accretion.
