This compelling new theory of physics challenges a century of mathematics-based physics. It solves an ever-lengthening list of physical mysteries left behind by modern physics. This innovative theory physically explains all aspects of physics, an achievement that leading physicists consider impossible. This third edition updates the theory and makes the book even more reader friendly. Its unique approach unifies physics by showing how everything transforms into everything else. Surprisingly, matter and energy are found to be much the same. This thought-provoking approach is unexpectedly simple and understandable. Its secret is to reverse the assumptions made by Einstein, to use basic principles in physics, and to fill space with spatial fluid. The result is a fluid-based theory of physics. This powerful new theory evolved over many decades. It agrees with experiment, and interrelates all aspects of physics. This theory provides a feeling of satisfaction because it makes the world around us far more understandable.
