This book relates to the physics of the most fundamental building blocks of the universe, vacuum species known as a strings, its energy, and properties. It details the fundamental principles behind creation and existence of the universe and its evolutionary history based on a new theory, the "E-theory". The book also covers important laws of classical physics and how it fits within the framework of this new theory. The theory presented in this book covers many of the fundamental phenomena that govern our universe. This includes gravity, electromagnetism, all fundamental forces, detailed structure of atoms, dark energy, dark matter, blackholes, and a brief overview of the big bang. Many existing theories in classical physics including Newtonian physics, general relativity, special relativity, fundamentals of electromagnetism, including many laws in classical physics are a natural fall out of the fundamental mathematics of this theory. I have used the proven and accepted physical properties of the universe disclosed in classical physics as a means of corroborating the results of this theory chapter by chapter and where appropriate. The theory will address many difficult concepts such as the nature of dark energy and dark matter, quantum entanglement, particle vs wave, structure of the blackholes, fundamental particles, entropy and time, just to name a few.
