===Stasis fields===
A Slaver [[Stasis (fiction)|stasis field]] creates a bubble of spacetime disconnected from the entropy gradient of the rest of the universe. Time slows effectively to a stop for an object in stasis, at a ratio of some billions of years outside to a second inside. An object in stasis is invulnerable to anything occurring outside the field, as well as being preserved indefinitely. A stasis field may be recognized by its perfectly reflecting surface, so perfect that it reflects 100% of all radiation and particles, including [[neutrinos]]. However one stasis field cannot exist inside another.  This is used in ''[[World of Ptavvs]]'' where humans develop a stasis field technology and realize that a mirrored artifact known as the ''Sea Statue'' must be actually an alien in a stasis field.  They place it with a human envoy, who is a telepath, and envelop both in field. By doing this, they unleash the last living member of the Slaver species on the world.
