By the way, a certain question about the atomic mass of Lithium is incorrect. As of today, the atomic mass of an element is calculated as abundance-weighted average of all stable isotopes (i.e. Li-6 and Li-7) in samples collected on Earth by a designated international commission[www.ciaaw.org]. Oh, and their value is only a recommendation.

Thus, the number programmed into the Leesha structure, 6.941, is only valid for Earth (i.e. another galaxy), and only as of today. Progenitors of the Andromeda galaxy would have certainly had a different number.
