Resumen de Ring of fire
John Preskill, a theoretical physicist at the California Institute of Technology in Pasadena CA, is scratching his head over the latest paradox to surface. Nicknamed the black hole firewall paradox, it comes about when one considers what happens to someone falling into a black hole. With the nearest black hole more than 1,000 light years away, the question is very much a theoretical one. Yet just by studying such a possibility, physicists are hoping to make a breakthrough in their efforts to combine general relativity and quantum mechanics into a theory of quantum gravity--one of the most intractable problems in physics today. Here, Ananthaswamy reports that falling into a black hole has never been more dangerous.
