The last 120 years of physics has radically changed our perception of reality many, many times.

Atoms were thought to be fundamental and then the electron was discovered in 1897. In 1919, the nucleus was discovered to be discrete positive charges of matter. In 1932, the neutron was discovered. The current model we are familiar with consists of a proton/neutron nucleus surrounded by an electron cloud¬†. Protons and neutrons however are not fundamental particles. They are composed of quarks and the force holding them together called gluons. Each proton and neutron is composed of 3 quarks bound with gluons, which carry…
