Can't find a thread about this
http://www.sciencealert.com/stephen-hawking-has-finally-published-his-solution-to-the-black-hole-information-paradox
>The problem is that, according to Hawking's best calculations, that (hawking) radiation would contain no useful information about what the black hole ate - the information swallowed up would have been lost forever. And that doesn't gel with our understanding of modern physics, which states that it's always possible to reverse time. In theory, at least, processes in the Universe will look the same if they're running forwards or backwards.
>But Hawking thinks he finally has a solution to the problem - black holes might actually have a halo of 'soft hair' surrounding them, which are capable of storing information.
>That 'hair' isn't actually hair - as you might have already assumed - but is actually low-energy quantum excitations that carry with them a signature pattern of everything that's been swallowed up by the black hole, long after it evaporates.
>But he admits: "It is certainly possible that, following the path indicated by this work, further investigation will uncover more hair of this type, and perhaps eventually lead to a resolution of the black hole information problem."
Thoughts?
