      Quarks and gluons are some of the fundamental particles that make up our Universe. More specifically, these are the particles of what we call the “strong force” and they all carry a “colour” charge. You can think of the colour charge in the same way that some particles have an electric charge, they just act through different forces. We have four types of force that we know of: strong, weak, electromagnetic, and gravitational.
      .
      The particles that we are used to seeing around us are made up of quarks and gluons. For example, the nuclei of the atoms that build everything around us are made from protons and neutrons. These protons and neutrons are themselves made from quarks and gluons. A proton has two “up” quarks and one “down” quark, whereas a neutron has one up quark and two down quarks.
      .
      Quarks and gluons are just some of the particles that make up our current understanding of particle physics – this is called the “Standard Model”. If you’d like to know more about all of these particles, check out this link https://home.cern/science/physics/standard-model 🙂
