Everything outside of these zones of stability are radioactive and devolve into pure kinetic energy over time. Furthermore, bismuth has some loose connections to UFOs and especially antigravity along with its electrical properties. Bismuth's counterspatial structure comes about due to it just barely being non-radioactive, and this trait expresses itself as what you could consider a "vortex" in its physical structure, that being the squares shrinking inward toward a central point. This hollow cube shape is common in alchemical study as one of the Platonic Solids, or the shapes God used in the act of creation.
As a side, Solgaleo is psychic not just because of space, but for a number of reasons relating to his third eye trait and his ultra wormhole travel. We could do a big autistic tangent on the topic if you want.
