| Still, the collapsar is an extremely attractive model that fits a wide range of observed gamma-ray bursts. |
| It was shown above that the Universe considered as a sphere of incompressible liquid is a collapsar. |
| A key feature of the collapsar winds is that they are capable of producing radioactive elements necessary to power a long-duration supernova light curve. |
| Hence they deduce that the observable Universe is a collapsar, a huge black hole. |
| Two papers scheduled for an upcoming Astrophysical Journal Letters appear to support the collapsar model. |
| The early detections are just what theorists need to refine their picture of collapsar fireballs, says astrophysicist Andrew MacFadyen of Caltech. |
