latetis

Latetis is a fictional material used in speculative fiction and world-building to illustrate latent energy and advanced materials. In typical portrayals, latetis is a dense, chemically complex substance that functions as a high-density energy carrier and structural material. There is no real-world element or compound by this name.

The name latetis is often linked to the Latin latere, meaning to lie hidden, chosen to evoke concealed energy. In works of fiction, the form is usually treated as a proper noun.

Physical properties: Latetis is described as having high energy density, strong thermal stability, and often a wide bandgap suitable for semiconductor use. Bonding is depicted as a mix of metallic and covalent character, allowing strength and tunable electronic properties. Some depictions also mention luminescence or self-healing under radiation.

Occurrence and production: In-fiction sources place latetis in trace deposits within meteorites or deep-crust ore, or it is synthesized in laboratory- or planet-scale reactors under extreme conditions with exotic catalysts.

Applications: Latetis powers fictional starship reactors, high-efficiency batteries, radiation-hard electronics, and protective armor. It is frequently used as a benchmark against which real materials are compared in world-building exercises.

Real-world status: Latetis has no standing in real science and is used for narrative or pedagogical purposes. It helps discuss what material properties would be needed to enable future technologies while clearly distinguishing fiction from reality.
