Astronomers say they have discovered a black hole so big that it challenges the theory about how they grow. Scientists said this black hole was formed about 900 million years after the Big Bang. But with measurements indicating it is 12 billion times the size of the sun, the black hole challenges a widely accepted hypothesis of growth rates. "Based on previous research, this is the largest black hole found for that period of time," Fuyan Bian, Research School of Astronomy and Astrophysics, Australian National University (ANU), told Reuters on Wednesday.
"Current theory is for a limit to how fast a black hole can grow, but this black hole is too large for that theory." The discovery was described in a study published Wednesday in Nature.
So far, roughly 40 quasars with redshifts greater than z = 6 have been discovered1, 2, 3, 4, 5, 6, 7, 8. Each quasar contains a black hole with a mass of about one billion solar masses (109 )2, 6, 7, 9, 10, 11, 12, 13. The existence of such black holes when the Universe was less than one billion years old presents substantial challenges to theories of the formation and growth of black holes and the coevolution of black holes and galaxies14. Here we report the discovery of an ultraluminous quasar, SDSS J010013.02+280225.8, at redshift z = 6.30. It has an optical and near-infrared luminosity a few times greater than those of previously known z > 6 quasars. On the basis of the deep absorption trough15 on the blue side of the Lyman-α emission line in the spectrum, we estimate the proper size of the ionized proximity zone associated with the quasar to be about 26 million light years, larger than found with other z > 6.1 quasars with lower luminosities16. We estimate (on the basis of a near-infrared spectrum) that the black hole has a mass of ~1.2 × 1010 , which is consistent with the 1.3 × 1010 derived by assuming an Eddington-limited accretion rate.

Just goes to show that the more we learn about our universe the less we actually know.

There was no big bang. Black holes create stars and eject them. Stars get lots of asteroids and matter in and eject planets. Black holes recycle an infinite universe that didn't begin with a big bang but does get renewed.

My take on Black Holes is that they convert matter into the fundamental energy in context of space-time.
Much like cube of ice melts into a fluid.
The Big Bang was an event space-time splintering the individual packets becoming what we now call matter.
