Quantum Energy Inequalitieseplace the classical energy conditions of classical general relativity. This chapter surveys the violation of classical energy conditions in QFT and the theory of QEIs. In particular, (a) the main properties of QEIs are indicated using the example of a free scalar field in Minkowski spacetime; (b) a

Probing Faster than Light Travel and Chronology Protection with Superluminal Warp Driveswe shall review the main features of these phenomena, in which spacetimes they appear to be realised, and explain why they are interconnected with the Einsteinian framework. We shall then discuss briefly the paradoxes related to the possibility of time travel and the proposed solutions. Finally, we

Self-Sustained Traversable Wormholesn that for every framework, the self-sustained equation will produce a Wheeler wormhole of Planckian size. Some consequences on topology change are discussed together with the possibility of obtaining an enlarged wormhole radius.

Warp Drive Basicsour this difficulty, we discuss a metric introduced by Krasnikov, which also possesses the interesting property in that the time for a round trip, as measured by clocks at the starting point, can be made arbitrarily short.
