Fundamental Units of Matter: Atoms, Quarks, and Leptons
The search for the fundamental units of matter has evolved over centuries. Early models identified atoms as the basic building blocks, as reflected in the periodic table, where each element is a specific kind of atom distinguished by its atomic number and properties . However, further discoveries revealed that atoms themselves are made up of smaller particles: electrons, protons, and neutrons -2023Hughes2023.
Quarks and Leptons: The Standard Model’s Building Blocks
Modern physics, through the Standard Model, identifies quarks and leptons as the true fundamental units of matter. Quarks combine to form protons and neutrons, which make up atomic nuclei, while electrons (a type of lepton) orbit the nucleus -2023Mohapatra2020Butter2023. There are six types of quarks, but stable matter is primarily composed of up and down quarks -2023Butter2023. Leptons, such as electrons, are also fundamental and not made up of smaller constituents .
Force Carriers and the Dual Nature of Light
In addition to matter particles, the Standard Model describes force carriers, or bosons, which mediate the fundamental forces. For example, photons carry the electromagnetic force, gluons carry the strong force, and W and Z bosons carry the weak force . Light, once thought to be only a wave, is now understood to also behave as a particle (the photon), highlighting the quantum nature of the universe .
Alternative Theories: Unitrons and Moulikana
Some theoretical models propose even more fundamental building blocks. The "unitron" model suggests that all elementary particles are made from smaller entities called unitrons, which possess positive or negative electric charge and interact via electric forces . Another proposal introduces "Moulikana" as the most basic unit from which all matter and energy are formed, aiming to explain the inter-conversion of matter and energy and phenomena like dark matter and dark energy . These ideas, while intriguing, are not part of mainstream physics.
The Role of Fundamental Constants and Units
The study of fundamental units also involves constants such as the speed of light, gravitational constant, and Planck’s constant. These constants help define natural units like Planck length and Planck mass, which are combinations of these constants and are used in theoretical physics to describe the universe at its most basic level Jj2021Gilliard2020.
Conclusion
The current scientific consensus is that quarks and leptons are the fundamental units of matter, as described by the Standard Model. Atoms are made of these particles, and their interactions are governed by force carriers like photons and gluons. While alternative theories propose even smaller constituents, such as unitrons or Moulikana, these remain speculative. The quest to understand the true fundamental building blocks of the universe continues, guided by both experimental discoveries and theoretical innovation -2023Forster2019Mohapatra2020+2 MORE.

The Theory of Unitrons - A Classical Physical Approach for Fundamental Particles and Forces
The Theory of Unitrons proposes that all elementary particles are composed of electric multipole composite unitrons, with the electric, magnetic, gravitational, and nuclear forces being manifestations of the attractive and repulsive forces of unitrons.
