Document Summary
Einstein looked into the forces first, particularly gravity. Quarks: thought to make up protons and neutrons. Antiquark: make up a meson (holds the nucleus together) Managed to unify two of the four forces in 1967, the weak and electromagnetic forces: provided insight into the strong nucleus force. Gluons: holds the quarks together in the nucleus: discovered through the stanford linear accelerator center. Quarks, electrons and neutrons are interacting with gluons, w- and z-bosons (strong and weak together) and photons. Generations: elementary particles, subatomic particles, three exact copies which are essentially duplicates of each other. These particles are in the standard model. Most successful theory of elementary particles, without taking gravity into account therefore is not the final theory. Would mean that the universe started as a single unified force insists that as the universe cooled, the forces cracked off from one another. Forces are broken, the universe expands exponentially. The false vacuum is the driving force of the expansion.
