This book identifies "dark" "matter" and explains how it has gone undetected for decades even though its nature is both simple and obvious. This book also carefully examines the foundations of modern physics and demonstrates clear conceptual inconsistencies that run throughout those foundations. Indeed, this work demonstrates that almost ninty-seven percent of the essence of the universe is a surprise to current physicists because the edifice that is modern physics is built on quick-sand. The universe is dark to current practitioners because their edifice long ago collapsed into a deep and unrelenting mire. Henceforth, it will not be possible to assert expertise in the fields of Mechanics, Gravitation, Electricity, Magnetism and Relativity without having reviewed and understood the ideas in this text. Such an assetion surely sounds like hyperbole, but, in fact, is understatement. Read this book and you will understand why and, in the process, will have a new and deeper understanding of how the universe really works.
