A key unresolved issue lies at the heart of our science -- the quest of Aristotle, Newton, Einstein, Hawking and many others, now widely known as the Theory of Everything. This ultimate understanding is expected to transform science and resolve its many mysteries -- all via one single overlooked principle in nature that will explain, simplify and unify everything. This quest has produced theories such as Special Relativity, General Relativity and Quantum Mechanics, enormous investments in powerful particle accelerators and space telescopes, and such recent pursuits as "Dark Matter" and "Dark Energy." But enormous problems remain: these theories, projects and pursuits are all completely separate and frequently incompatible, presenting unresolved abstractions, speculation, paradoxes and mysteries that often even violate our laws of physics, upon closer examination. As a result, the Theory of Everything continues to elude us, with no clear way forward. The Final Theory clearly shows why...
