   Half of the mass of an early galaxy is in its central black hole

   There just isn't time for something that big to grow from a supernova remnant.

     @arstechnica One implication of this is that a supermassive black hole could have formed from the irregular density of the primordial universe, rather than by accretion. This black hole is from a very young portion of the universe...would ones that size have evaporated in our portion of the universe?
