Galileo established how objects of various mass, when released simultaneously, hit the earth at the exact same instant. Sir Isaac Newton identified that no matter what was falling, if free of drag, fell at an accelerating rate of 9.81 m/s2. Einstein spoke of spatial distortion of light beams as the reason why we are all bound to Earth, yet neither he nor anyone else recognised what causes gravity. First tackled in his earlier book ‘Gravity’, this is David G.H. Crawford’s attempt to have the scientific world reign its resources back into looking at this fundamental question. Having spent a lifetime investigating and advising on problems concerning the operation of electromagnetic powered, water supply and waste-water processing systems, David has an intense, and hands on, interest in this topic. This book explains David’s radical new theory of seeing gravity as the concentric force difference between dark energy and neutron-dragged mass. To finally understand what gravity is will open the world to many advances – in which concentric gravity, once realised, can be utilised in many environmentally friendly ways. A thought-provoking book by a free thinker which encourages us to recognise the historic misconception of gravity.
