Ananthaswamy's excellent article reminded me of work by physicist on the . Swingle has that black holes must represent Nature's most efficient quantum computers. This, with the “holographic principle” that a 3-dimensional universe maps on to a surface, raises the distinct and disturbing possibility that we really do live in a computer simulation, running on the event horizon of a black hole.
