"Nobel laureate Gerard t'Hooft, who was present for the discussion, has been thinking about information loss in a similar way, and he cited several papers he has published on the subject. It will take more discussion — and much comparing of math equations — to establish what's new about Hawking's theories in relation to t'Hooft's, and whether Hawking has overcome some of the issues associated with earlier iterations of the idea."
