Even if 1000 physicists agreed that the universe is not 'serializable' (and I'll have no idea if they would - last I heard was that they weren't really agreed on what time itself was), do you truly believe that there is mileage in not forcing a database to have exactly one value at each point in time, *whenever such a value is requested*?
