HTTP:: Early Black Holes Prevented Star Formation
--------
According to a new complex computer simulation, it would appear that the earliest black holes that where formed after the Big Bang were in fact a lot smaller than the giants they are today. Also, the simulation revealed that older theories, which held that the formations accumulated mass quickly and gobbled up matter at fast rates, were misplaced and incorrect. The team behind the new study, which appears in an upcoming issue of the Astrophysical Journal Letters, says that the key to understanding black hole formation and evolution is looking at the stars that spawned them. The scientists, from the Kavli Institute for Particle Astrophysics and Cosmology, a division of the Stanford Linear Accelerator Center (SLAC) National Accelerator Laboratory, in Menlo Park, California, believe that, in the early Universe, the first black holes were formed by exploding stars. But, even before they collapsed upon themselves, these stars burned for several millions of years, removing most !
amounts of cosmic gas and dust from their immediate vicinity, through either heat, solar winds or massive amounts of radiation. As soon as the collapse occurred, the newly formed black hole, not that impressive in size, would have immediately begun feeding, except for the fact that there was nothing to feed on. “It has been speculate...
