The "particles"[1] known as Primitions are one of the last class -3 objects. They're "particles" that predate the existence of most if not all of the Hypercosmos. Due to their size (or lack thereof), researching them is incredibly difficult. These "particles" have helped has us learn more about what went on before the Hypercosmos existed. Primitions have a lifespan in the metafinities[2]. Primitions are still the most common "particles". Primitions rarely ever form nowadays, but 10^72 have been observed forming. Currently, every Primiton that has ever existed still exists.
