Hawking: black holes do not exist
Nature News announce a job awaiting publication signed by the great Hawking in which the assertion that the black holes do not miss anything, according to quantum physics, could not be true anymore.

The black holes are an infinite source of discussion topics for both astrophysicists who try to observe them, and for theorists, who seek to explain them through general relativity and quantum physics. Hawking is one of the most important exponents of the second category and each of its opinion has to be taken into account, because he has done a lot over the knowledge of the black holes.
After studying for a long time what is happening around the event horizon, the insurmountable barrier between the inside and the outside of a black hole, researchers now seek to overcome this concept by transforming the wall into a floating barrier that could be overcome. To cross the event horizon would solve the information paradox, a paradox created by the loss of information that occurs whenever the matter falls into a black hole. In the final analysis, this is in contrast with the second law of thermodynamics because the loss of information would lead to a decrease in entropy of the Universe.
Considering what is happening around the event horizon, years ago, Hawking proposed a mechanism to generate pairs of entangled quantum particles (Hawking radiation), one of which falls into the black hole while the other runs away, taking away a small part of energy of the black hole. To carry information when the particle goes, it should break its entanglement with the other particle, a process that would create a firewall around the event horizon.
A situation exemplified in the famous virtual experiment that wonders what might happen to any astronaut who had the unfortunate idea to get closer to the event horizon for scientific research or for curiosity.
Now Hawking proposed a third way (certainly not to save the astronaut), which uses the quantum fluctuations of its radiation. The event horizon would form a layer of turbulent Hawking radiation which would allow the escape of a fraction of the particles and the transfer of information from the inside to the outside. There would be no longer an impassable horizon, but a fluctuating horizon.
Hawking has proposed this idea in a conference that held in August 2013 via Skype to a meeting at the Kavli Institute for Theoretical Physics in Santa Barbara, California, which is now a preprint entitled for Information preservation and weather forecasting for black holes available on ArXiv .
The work, which Nature News describes as rather vague, has not been yet accepted, but which referees would have the courage to oppose the great Hawking?
Preserving the second law of thermodynamics is reassuring but, more prosaically, what would be the consequences of this turbulent layer for those who seek to study the black holes through the radiation they emit beyond the event horizon (that is impassable or oscillating)?
