Stephen Hawking ‘There are no black holes’ Stephen Hawking claims that two of the properties most often identified with black holes -- the singularity and the event horizon -- dont exist, at least not in the way that was previously thought. Therefore, black holes themselves cant exist. At the moment, he hasnt offered up a new name for the objects that look and act like the objects previously referred to as black holes. In Information preservation and weather forecasting for black holes, Hawking argues that there is no event horizon, nor is there a singularity siphoning in all matter, light and information and destroying it. He claims that information about this material -- which is communicated through Hawking radiation -- would not be destroyed, merely reconfigured to such an extent that it would be impossible to reconstruct what the objects that fell into the hole originally were. Physicist Don Page told Nature that it would be worse than trying to reconstruct a book that you burned from its ashes, which is why Hawking compared it to weather forecasting, which is possible in theory, but rarely accurate in practice. The consequences of Hawkings theory would be that information, however scrambled, could escape a black hole -- and given that, according to Hawking, there is no escape from a black hole in classical [quantum] theory, that means that black holes as we know them cannot exist.

Therefore, if I step on a roach, the insect is not destroyed, merely reconfigured in such a way as to be impossible to reconstruct. rawstory/rs/2014/01/24/stephen-hawking-dashes-fanboy-dreams-there-are-no-black-holes/
