Abstract: The Averaged Null Energy Condition (ANEC) states that the integral
along a complete null geodesic of the projection of the stress-energy tensor onto the
tangent vector to the geodesic cannot be negative. ANEC can be used to rule out spacetimes
with exotic phenomena, such as closed timelike curves, superluminal travel and wormholes.
We prove that ANEC is obeyed by a minimally-coupled,... read more
