Informacinius
Informacinius is a fictional chemical element used in speculative science and science fiction to explore ideas about information density and atomic-scale storage. The name combines informatio, Latin for information, with a conventional suffix used for invented elements. In many fictional periodic tables, informacinius is assigned an atomic number well above the known elements, placing it among superheavy metals. Its symbol is often given as Ic or Inf.
In imagined accounts, informacinius is described as a heavy, highly conductive metal with a stable, rigid lattice
Applications and theoretical role commonly described include ultra-dense memory devices, quantum information storage, and secure data
In fiction and scholarly thought experiments, informacinius serves as a placeholder to discuss the physical limits
