Hadronium

Hadronium is a form of electromagnetically interacting exotic matter that is, essentially, a glorified nucleus, though typically with far lower densities. Discovered late in the 22nd century, it is so termed because it responds to the strong nuclear force. As it requires mirror matter to create stable structures, the paucity of this substance makes it somewhat precious, even after the Mynoth process enabled its 'rapid' creation.

It forms via certain high-energy interactions being able to respond to both mirrored and normal electroweak and color charges. Normally highly unstable, it is possible to carefully arrange structures that will remain in a stable state until sufficiently excited so as to cause a breakdown. While immensely strong, it is more common to use smaller components as building blocks for larger structures, in order to mitigate the damage caused by one component being forced to decay. Other, more advanced constructions actually have a sort of self-repairing ability, though even these can be overwhelmed.

While hadronium is capable of reaching tensile strengths exceeding that of the atomic nucleus, such is not its typical usage. For one, such strength comes with incredible density, reaching a 'mere' five million tonnes per cubic centimeter. For two, denser designs are more difficult to construct. Third, and far more critically, it is nearly impossible to make such constructs stable without the aid of patterns, and while hadronium may be rare, mobius patterns are more precious still.

Since it possesses both a mirror and normal electric charge, along with an extreme density, few substances escape its notice - it responds to all electronuclear forces, both mirrored and normal, as well as its own. For this reason, it makes an excellent neutrino shield - both to detect and prevent detection of neutrinos, along with other uses.

Able to produce powerful, localized electric fields, significant positive charges can be used to create electronium as an effective part of its structure. Such a compound is called exomatter.
