Stephen Hawking finds a way to preserve conservation of information in the universe

His flash of inspiration came when listening to a lecture in April
about what are called super-translations, a bit of the heady branch of
mathematics known as group theory. Dr Hawking thinks that incoming
particles shed their information like a coat as they pass into a black
hole, leaving it draped on the event horizon itself.
Super-translations mathematically describe how that information influx
can slightly jiggle the fabric of space at the horizon, in turn
shifting around when and how the black hole radiates. Something of the
incoming particle's information is turned into the when-and-how of
Hawking radiation: information is transmuted, not lost.
