This is the most significant breakthrough in over 100 years. Scientists, such as Einstein, Hawking and others have been seeking a “Grand Unified Theory, GUT” that would unify electromagnetic, gravity and other forces without success. Since the force of gravity is an electrical force their search...

Sometimes things are not what they seem to be. We can experience something and attribute it to a long held belief. Without questioning it, we may not begin to fully understand the processes in play.The title of this book states a new terminology. In my years of study and pondering over gravity,...
