Elementary particles are particles with no measurable internal structure; that is, it is unknown whether they are composed of other particles. [1] They are the fundamental objects of quantum field theory. Many families and sub-families of elementary particles exist. Elementary particles are classified according to their spin.
Neutronium, hypothetical nuclei consisting only of neutrons (more than one). Examples include the tetraneutron. Preons were suggested as subparticles of quarks and leptons, but modern collider experiments have all but ruled out their existence. Rishons, particles from the Rishon model of preons. From superseded and obsolete theories

Hypothetical particles and states of matter that have not yet been encountered, but whose properties would be within the realm of mainstream physics if found to exist. Several particles whose existence has been experimentally confirmed that are conjectured to be exotic hadrons and within the Standard Model .

In particle physics, the term particle zoo [1] [2] is used colloquially to describe the relatively extensive list of known subatomic particles by comparison to the variety of species in a zoo. In the history of particle physics , the topic of particles was considered to be particularly confusing in the late 1960s.
Permeates all universes and passes among dimensions. Parker Particles Marvel Comics: Parker Particles are a form of energy discovered by Peter Parker that are tied to the universe's expansion and thus possess theoretically infinite power. Young hero Alpha gained his powers after being exposed to Parker Particles during a school trip. [106] Philote
