Seaborgium

Seaborgium is a synthetic and highly radioactive element produced exclusively through human-made nuclear reactions and holds no significant presence in natural astronomical contexts. Its artificial creation results in seaborgium being exceptionally rare beyond Earth, contributing to its negligible astronomical relevance. Seaborgium's isotopes have exceedingly short half-lives, often lasting from milliseconds to minutes, emphasizing its absence in celestial bodies or cosmic environments. The synthetic nature of seaborgium confines its existence primarily to controlled laboratory conditions, such as in nuclear reactors or because of nuclear processes.
