This book is a discussion of the work being done in the quest to obtain a Theory Of Everything. An acceptable theory of everything (T.O.E.) is the ultimate goal of most cosmologists and physicists. A theory of everything would explain all observational data by unifying all of the 4 known fundamental forces into one verifiable and validated theory. This would then become known as "The Law of Everything." Grand Unification Theory was a major step towards this goal by unifying the weak, strong and electromagnetic forces in one model. A T.O.E would complete the process by unifying the gravitational force with the other 3 forces mentioned above. The testing of hypotheses alone deals with time scales on the order of 10 DEGREES-12 seconds, length on the order of 10 DEGREES-35 meters and temperatures approaching 10 DEGREES32 Kelvin. Most of the testing is done at The Large Hadron Collider at CERN in Switerland. The discovery of the Higgs Boson was one major step in this direction. Most T.O.E.'s tend toward the use of "String Theory" at the time of this publication. One thing to know, if we take into regard the lessons of history, is that a T.O.E. will not be the end of the questions regarding the universe but it will open doors that have previously gone unentered. The applications of such a theory remains to be seen.
