Averaged Null Energy Condition.

Urban, Douglas.

Abstract: The achronal averaged null energy condition (ANEC) is a sufficient condition to rule out exotic spacetimes such as time machines and wormholes. We review how achronal ANEC is used to prove such restrictions, and the status of the condition. We find counterexamples to achronal ANEC using conformally coupled scalar test fields in a conformally flat background. These examples involve rapid ... read more
