In particle physics, preons are "point-like" particles, conceived to be subcomponents of quarks and leptons.

ok,look you're are being WAY curius now. We absolutly have no comprehention of this. one theroy (called, as you can imagion) String theroy, says that any funimental particle, one that seems to have 0 size, is actually a teeny tiny vibrateing string. this is the smallest unit of matter or energy. if a Preon is a string, that means that there is nothing smaller. It trully is funimental.

• Preon was first introduced in 1974 in particle physics.
• preons are "point-like" particles, conceived to be sub-components of quarks and leptons.
• Preon term is introduced to provide a framework for dealing with binary encoded data; or more specifically, it aims to deal with situations in which bytes are considered to be overkill. The project is named after the "point-like" particles, conceived to be sub-components of quarks and leptons.
• Peons are very small particles that you don't see with the naked eye, but you probably rely on them without knowing.

Nothing known is denser than the densest of neutron stars except a gravitational singularity (Black hole). The upper limit of the inward pressure a neutron star can handle before further implosion is dictated by neutron degeneracy pressure.

However, theoretically (Not yet observed but probably out there) the next step would be a quark star, that is, a star that is held from implosion by quark degeneracy pressure. Then the next stage would be a black hole.

Technically there is yet another stage in between a qaurk star and a singularity called preon degeneracy prssure but the preon models are too flawed to even consider.
