temporarilyite
Temporarilyite is a hypothetical mineralogical concept that describes a substance possessing properties that are inherently transient or subject to rapid change. It is not a recognized mineral in official classifications like the International Mineralogical Association's list. The term "temporarilyite" is often used in theoretical discussions, speculative fiction, or to describe materials exhibiting extremely short-lived states or phases. Such a substance would likely be characterized by a high degree of instability, potentially decaying, transforming, or ceasing to exist under normal environmental conditions. Its existence would be dependent on a very specific and potentially fleeting set of circumstances, making its observation and study exceptionally challenging. Research into materials that exhibit temporary properties, such as metastable phases or substances with very short half-lives, might draw inspiration from the idea of temporarilyite, even though the mineral itself remains theoretical. The concept highlights the possibility of matter existing in states that are fundamentally impermanent.
