Laurentium

Laurentium is a fictional chemical element that appears in science fiction, speculative science, and educational thought experiments. There is no real-world element by this name, and its properties vary across works. In most depictions, Laurentium is a synthetic, superheavy metal with an atomic number well beyond those of known elements. Authors typically describe it as highly unstable and extremely radioactive, with short-lived isotopes that challenge production and handling in laboratory settings. Some portrayals assign it unusual electronic properties, such as high electrical conductivity or unconventional superconductivity, while others emphasize strong redox activity or inertness depending on the fictional chemistry framework.

Production in stories usually involves advanced laboratories capable of heavy-ion fusion, often by bombarding heavy target nuclei with high-energy beams to reach the superheavy element regime. Because of short half-lives, Laurentium is frequently observed only as fleeting traces or within sealed containment cells, limiting its practical study to imagined scenarios. Possible applications in fiction range from compact energy storage and novel propulsion to exotic quantum materials; in some narratives, Laurentium enables breakthroughs that reshape technology or geopolitics.

Etymology varies: Laurentium is commonly named after a fictional scientist, institution, or location such as the Laurent Institute or Dr. Laurent. It serves as a linguistic device to explore the limits of chemistry and nuclear physics within speculative settings.
