The Question Stephen Hawking Is Working On Now

WIRED: [The mathematician] Roger Penrose has mentioned that you always ask awkward questions. What questions are you asking right now?

Stephen Hawking: I’m working on how to reconcile the apparent loss of information when a black hole evaporates with our understanding of physics that information is never lost. I raised the question 40 years ago and, despite a large number of papers since, no satisfactory resolution of the paradox has been proposed. Indeed, it has been shown that there is a contradiction between information not being lost and the usual assumption that physics is local. It has been suggested that the resolution is that there is a firewall just outside a black hole that would burn up anything falling in, but I don’t believe in firewalls. Instead I think space-time is warped.
