On March 28, 2011, the Swift Burst Alert Telescope detected a gamma-ray event that, in contrast with any previously observed gamma-ray burst, remained bright and highly variable for 48 hours. The gamma-ray emission was accompanied by bright x-ray emission that continued for two weeks. Astrophysicists attributed this event to the tidal disruption of a star by a black hole in the center of a distant galaxy. I would argue, however, that it would have been more accurate to describe this event as the tidal disruption of a star by a compact object. This distinction is important because the black-hole model has serious problems. The March event lends support to a heretical idea: that black holes do not exist.

The brightness of the gamma-ray and x-ray emissions suggests they are coming from a jet of charged particles moving at nearly the speed of light, but there is no obvious reason why the tidal disruption of star by a black hole should give rise to such a jet. In fact, the astrophysical community has been struggling to explain the observed ubiquity of jets. A leading idea is that, in the presence of a external magnetic field, electromagnetic energy is extracted from a rotating black hole and used to accelerate charged particles. The source of the field could be the disk of material swirling around the black hole. Yet disks do not generate fields that are strong enough to produce well-collimated beams of charged particles.

" I know George Chapline since 1967 and I independently got the dark star idea he is talking about though not in as great detail. George is a very smart guy. What non-experts don't get is that the outside of the dark energy star is pretty much same as a black hole. It's only the interior that is different - no singularity." - Jack Sarfatti
