Black Holes Beyond Imagination
From the American Astronomical Society (AAS) meeting in Honolulu: The Chandra X-Ray Observatory has found in cluster 3C438 one of the most energetic events ever. This cluster has mass a quadrillion (10^15) times that of our Sun. The easiest explanation is that this is the collision between two giant objects. However, only one peak in X-Ray emission is visible. If two clusters collided there would be two peaks.
Evidence indicates that this is the ouburst from a single massive Black Hole. If so, it is the largest outburst ever seen. Such a massive flow of energy would require a Black Hole to swallow 30 billion solar masses over a period of only 200 million years, or 150 Suns each year. Old theories of Black Hole and cluster formation can not explain this.
Using the XMM-Newton telescope, graduate student Laura Brenneman has found that the central Black Hole in galaxy MCG-6-30-15 is spinning at least 98.7 percent of the maximum rate allowed by General Relativity. It hjas been thought that supermassive Black Holes form via collisions between smaller objects. If so, their spin rate would be small because different angular momenta would cancel out. This Black Hole must have grown on its own, by accretion.
Everywhere we find galaxies and clusters they are anchored by central singularities. Increasing evidence suggests that supermassive Black Holes are primordial, formed very shortly after the Big Bang. Size of a primordial Black Hole is limited by a horizon distance related to the speed of light. All these discoveries point to a "c change" in physics.
