Gluon field

A gluon field is a special type of invisible field that exists all around us in the universe. They are very important because they are the thing that holds particles like protons and neutrons together in atoms. Gluons act like sticky glue, sticking protons and neutrons together so they can form atoms. Gluons have special properties that make them so sticky, and these properties are such that they are both attracted and repulsive at the same time. This helps keep the protons and neutrons in place so that atoms can form.
