Trope-a-Day: Human Popsicle
Human Popsicle: Cryostasis used to be a standard way of storing people, and was taken advantage of for a variety of purposes, specifically including the Deep Star projects (subluminal interstellar colonization of the Thirteen Colonies, with ships full of frozen people), and, in the time after the prospect of fixing the dead was mooted but before the technology to do so was available, freezing something very close to everybody who died accidentally “for later”, in the Vaults of the Dead Awaiting. Hates the permadeath, they does. Some people, chrononauts, even used it electively for, to be closest to the spirit of the trope, deliberate one-way time travel into the future. See history while skipping the boring parts!
In the modern era, cryostasis is an archaic technology, mostly replaced with digital archiving for minds and the rather more high-tech and less damaging/risky nanostasis for organic bodies, but the effects and the purposes for doing it remain much the same.
