Explain Chronology protection conjecture

Chronology protection conjecture (S.W. Hawking): The notion that the formation of any closed time like curve will (automatically) involuntarily be destroyed by the quantum fluctuations as soon as it is made. In another words, the quantum fluctuations prevent the time machines from being made.
