# Cryonics **Entity class:** Preservation practice **Domain:** Cryobiology / Life extension **Maturity:** Developed ## Definition Cryonics preserves a legally deceased person's brain or body at very low temperature in the hope that future technology may make repair and revival possible. ## Mechanism and significance It is a speculative preservation strategy rather than an established medical treatment, and its strongest claim concerns retaining information that would otherwise be irreversibly lost. ## Relationships - **Research dossier:** [[research/ASI and RSI Timeline Research Moonshots|ASI and RSI Timeline Research Moonshots]] - **Ontology route:** [[ASI and RSI Timeline Ontology#Generative Humans, Continuity, and Presence|Generative Humans, Continuity, and Presence]] - **Primary fields:** [[Digital Human Twin]] · [[Machine Succession]] · [[Posthumous Avatar]] - **Adjacent concepts:** [[AI-Mediated Personality Reconstruction]] · [[Alcor Life Extension Foundation]] · [[Behavioral Continuity]] · [[Structural Continuity]] ## Sources and provenance - [[research/ASI and RSI Timeline Research Moonshots|ASI and RSI Timeline Research Moonshots]] — immediate source for this node's role in the broadcast research map. ## Evidence boundary The research dossier establishes why this entity or concept belongs in the Moonshots ontology.
