This book presents a solution to the gravitational wave and the structure of the universe by means of the Dot-Wave theory. There are three kinds of waves in the universe. There are plus dot-waves, minus dot-waves, and bi-polar or photonic dot-waves. In addition there are three different forms of momentum for each of these waves. There are linear and angular momentums which are well known. There is spherical momentum which produces gravity and the gravitational wave. This is explained in the book. The book also explains spherical, angular, and linear Doppler space time. The book combines the concepts of Einstein and Quantum Mechanics into a complete Unified Theory using Engineering level algebra which will be easily understood by the average scientifically inclined high school student. The book calculates the number of dot-waves in the entire universe. The charge of and the equivalent mass of each dot-wave is calculated. The Theory uses a modified Eddington number for the equivalent number of protons in the universe. The dot-wave equation for the mass of the universe has a phase angle associated with the vector. Eddington's number enables the rotational velocity of the universe be calculated. The rotational velocity causes the universe to look the way it is. The dot-wave gravitation equation gives us an age of the universe since the big bang to be 13.78 billion years which agrees with the astronomical calculation of 13.7 plus and minus 0.1 billion years. This is derived from the equation of the expansion of the hydrogen atom from the time of the big bang. The book provides a complete solution to the universe from the time when space started to contract and the dot-waves started to oscillate. The potential energy of space time was converted into the kinetic energy of the dot-waves. As the universe shrunk to a zero size the dot-waves converted into a high energy black hole which exploded producing billions of smaller black holes which then exploded to produce billions of galaxies. The black holes are explained along with worm holes and white holes. Gravity is the result of the radiation of dot-waves from particles, sub-particles, and photons. The number of dot-waves within the proton, electron, and neutron are calculated. Matter will lose their dot-waves slowly by radiation which causes the dark matter and dark energy in the universe. The book describes Doppler Space Time which is a variation of Einsteinian space time with Doppler equations added to it. Orbital and Spherical Doppler space time also presented. The formula for the conversion of mass to charge is shown. This enables the units of kilograms to be replaced with the units of coulombs, meters, and seconds. The gravitational constant is shown in electrical terms. The book looks at the universe from both an electrical and mechanical perspective. It also discusses Einsteinian relativity and Quantum Theory and how they relate to the Dot-wave theory. The math in the book uses only algebra since the basic structure of the universe is rather simple to understand. This is because the invisible universe is a rather simple place while the visible universe is extremely complicated. The equations of a snowflake are very difficult to describe but the dot-wave equations of gravity are rather simple. This book is written with simple equations from an Engineering perspective. The average reader with simple algebra skills will have no trouble understanding the theory and equations. The book is the result of 34 years of study to solve the greatest problem that the greatest minds have not been able to solve. Gravity is both tough and simple. If you know the answer it is simple. If you do not know the answer it cannot be readily solved. You cannot measure a single dot-wave but you can measure the effects of billions and billions of dot-wave as has been done recently by the gravitational wave data.
