    "abstract": "Hardy\u0027s theorem states that the hidden variables of any realistic theory of\nquantum measurement, whose predictions agree with ordinary quantum theory, must\nhave a preferred Lorentz frame. This presents the conflict between special\nrelativity and any realistic dynamics of quantum measurement in a severe form.\nThe conflict is resolved using a `measurement field\u0027, which provides a timelike\nfunction of spacetime points and a definition of simultaneity in the context of\na curved spacetime. Locally this theory is consistent with special relativity,\nbut globally, special relativity is not enough; the time dilation of general\nrelativity and the standard cosmic time of the Robertson-Walker cosmologies are\nboth essential. A simple but crude example is a relativistic quantum\nmeasurement dynamics based on the nonrelativistic measurement dynamics of\nL\\\"uders.",
