Protonides
Protonides are a hypothetical class of particles that are proposed to be fundamental constituents of matter, similar in concept to elementary particles like quarks and leptons. The term "protonide" is not part of the Standard Model of particle physics or any widely accepted theoretical framework. It appears to stem from a theoretical exploration of more fundamental building blocks that might compose protons and neutrons, which are themselves composite particles made of quarks.
The idea behind protonides suggests that protons, and perhaps neutrons, are not fundamental but are instead
If protonides exist, they would necessitate a revision of our current understanding of the subatomic world.
