Paper Abstract

This paper focuses on the recently established phenomenon of negative-phase-velocity (NPV) propagation of electromagnetic waves in the context of relativity, both special and general. Different observers in different states of uniform motion with respect to a material fragment may arrive at different conclusions on the possibility or impossibility of NPV propagation in that material. Also, conditions for NPV propagation may be satisfied in gravitationally affected vacuum. NPV propagation may thus be possible in scenarios encompassing space exploration, navigation, and communication; remotely guided extraterrestrial manufacturing industries; and the unraveling of the evolution of our universe after the last Big Bang.
