Mineralus
Mineralus is a hypothetical mineraloid that has been proposed in speculative geological and extraterrestrial mineralogy contexts. It is not a recognized mineral or element in standard scientific classification. The concept of mineralus often arises in discussions concerning the formation of new materials under extreme or unusual conditions, such as within planetary cores or during the early stages of planet formation. Its potential composition and properties are purely theoretical and depend heavily on the specific hypothetical scenario being considered. Researchers exploring the limits of material science and geochemistry might use "mineralus" as a placeholder term for a substance whose properties are not yet understood or characterized. The existence and nature of mineralus remain unconfirmed and are subject to the ongoing development of scientific understanding.
