Chronology Protection Agency It seems that there is a Chronology Protection Agency which prevents the appearance of closed timelike curves and so makes the universe safe for historians. Stephen HawkingTemporal Paradoxes - John Ashmead 20 http://www.timeandquantummechanics.comMonday, March 21, 201120 21. Weak energy condition If averaged energy positive, no wormholes But, beware of quantum uctuations, black swans, and circular arguments.Temporal Paradoxes - John Ashmead 21 http://www.timeandquantummechanics.comMonday, March 21, 201121 22. Novikov consistency conjecturethe only solutions to the laws of physicsthat can occur locally in the real Universe arethose which are globally self-consistent.

Quantizing the world For success & failure, there is no impact of the decision: the decision qubit is lost in the environment. For self-fullling (O), the quantum mechanical matrix is 1, which passes up and down through. For self-defeating (P), the quantum mechanical matrix is the spin-x matrix, which ips up & down.Temporal Paradoxes - John Ashmead39http://www.timeandquantummechanics.comMonday, March 21, 201139 40.
