Eternons continuously instill  into the human mind a deeper knowledge of the universe. Physicists have presently a model of the Cosmos of great simplicity and elegance. It may be summarized as follows:

1. The fermions, named for the physicist Fermi, constitute matter as we know it.
Quarks assemble into protons and neutrons to form the nuclei of atoms.
Electrons fly about these nuclei in somewhat circular orbits.

2. The bosons, named for the physicist Bose, carry the fundamental forces between the particles of matter.

b) The whole universe obeys a combination of four fundamental forces between particles:

1. The strong nuclear force holds together protons and neutrons.
The bosons carrying this force are the gluons.

2. The electromagnetic force binds atoms and molecules.
The bosons carrying this force are the photons we observe as radio waves, infrareds, visible light,        ultraviolet, and X and gamma rays.

3. The weak nuclear force is responsible for the radioactivity of atomic nuclei.
The bosons carrying the weak force are the intermediate bosons.

4. The gravitational force, is responsible for the attraction between   large scale bodies.
The bosons carrying the gravitational force are the gravitons.

1. Einstein’s Theory of Relativity best describes gravitation and large objects. The laws of the universe are the same for all observers. The velocity of the photons of light is constant and can never be reached by material particles. Mass and energy are equivalent. Space is curved by masses, somewhat like a rubber sheet is deformed by heavy balls lying on it.

2. the Quantum Theory best describes the three forces other than gravitation and very small objects. Energy is emitted in indivisible units called quanta. Quanta are both waves and particles. Quanta do not allow the same definite observations as do large objects.
