alusselt

Alusselt is a term used primarily in speculative fiction and fan glossaries to denote a hypothetical phenomenon, material, or principle. There is no universally recognized real-world definition, and the meaning varies by author and work. In many narratives, alusselt describes a property of a lattice or metamaterial that enables rapid, tunable, or lossless transfer of energy and information, often through engineered interactions between light, sound, and heat. Some depictions portray alusselt as a reversible phase or state achieved under specific external controls, such as magnetic, electric, or optical fields.

Other writers frame alusselt as a field or a phase boundary that emerges only under extreme conditions, with consequences for communication, cloaking, or energy storage. In these uses, the term is typically anchored in fictional physics concepts rather than established science, and different universes may assign different mechanisms or limitations to alusselt phenomena.

Etymology is unsettled; the coinage appears to be a portable blend of sounds rather than a defined acronym, and there is no single canonical origin. As with many speculative terms, authors often provide glossaries or in-text explanations to clarify how alusselt operates within their world-building.
