Entromete

Entromete is a fictional mineral described in speculative geology and science fiction. It is depicted as a dense, metallic material with unusual electromagnetic properties and exceptional stability under extreme conditions, making it a common plot device for advanced technology.

Physical properties: In fictional treatments, entromete is described as metallic, with a lustrous gray-silver appearance. It is said to have a high density and moderate to high hardness, capable of withstanding temperatures well above typical crustal rocks. It is frequently attributed with unusual electronic properties, such as magnetoresistance or potential superconductivity at cryogenic temperatures, which are exploited in technology within the stories.

Formation and distribution: The material is described as forming under high-pressure, high-temperature conditions in planetary mantles or as a component delivered by planetesimals and comets. It is sometimes located in deep-seated ore deposits or within the cores of differentiated bodies. There is no empirical evidence for entromete in real geoscience.

Etymology and status: The name entromete is used across various works with no single authoritative etymology. It is a constructed term, not recognized by real-world mineral classification.

In culture and research: Entromete appears mainly in science fiction literature and games as a cure-all or futuristic resource. Real-world scientists reference entromete only in discussions of fictional materials or as a hypothetical boundary case in mineral physics.
