The History of Cosmology and a Theory of Everything

The history of cosmology is interesting and full of important and significant visions, thoughts, results and important conclusions from the Greek world view to our present time. At the beginning of the science of cosmology there were some simple scientific speculations and disciplines. Now, by its end at the beginning of 21stcentury, there is a Theory of Everything (ToE) which represents the final comprehensive description of the whole universe from its origination from the primordial matter and original gas and its evolution through billions of years to its present status.Within the context of the Theory of Everything, nearly all major problems in physics and cosmology are solved, such as the determination of the original universe matter, the initial singularity in the Big Bang Theory (BBT), the combination of four fundamental forces, the cause of inflation, the origin of chemical elements, the puzzle of dark matter and dark energy, the flatness problem, the horizon problem, the disappearance of antimatter in addition to supposing and discovering the fifth fundamental force in the universe, the cohesion force, which maintains the observed universe (stars, planets, galaxies) and the non-observable universe consisting of dark matter and dark energy.The most important properties of our universe are: The universe is homogenous and isotropic at large scales, the universe is expanding and accelerating. The Cosmic Microwave Background (CMB) which represents the relic of the universe when it was very hot is detected and its properties examined.The main aim of this book is to present as possible as a comprehensive vision and a complete investigation of the development of the science of cosmology.
