Carlsonin

Carlsonin is a fictional chemical element and material used in speculative fiction and tabletop settings. In its fictional canon, Carlsonin is a lightweight metal with exceptional electrical conductivity, high strength, and notable resistance to corrosion. The element is assigned the symbol Cn and an atomic number in the 150s range within the story’s imagined periodic table.

Properties and production: Carlsonin is described as having a density around 4.7 g/cm3 and the ability to form stable alloys with magnesium and titanium. It is said to exhibit superconductivity at temperatures near 230–260 kelvin under moderate pressures, making it attractive for energy transmission and compact energy storage. In many stories, Carlsonin is produced by specialized smelting processes that require high-energy inputs and rare ore deposits located in remote astrophysical environments.

Discovery and etymology: The material is named after fictional physicist Dr. Carlson, credited with its discovery during expeditions to the Carlson Highlands on the planet Asterion in the late 22nd century. The term has since become a staple in world-building as a plot device for advanced materials.

Applications and challenges: Within its fiction, Carlsonin enables lossless power cables, high-capacity batteries, and components for spacecraft habitats. Its scarcity and expensive production, coupled with radiation sensitivity in some narratives, create ethical and logistical challenges for researchers and industries based on Carlsonin.
