"Physicist Martin Walsh has studied gravitational fields for over 20 years. Following from the pillars of science; Euclid, Leibniz, Kepler, Descartes, Newton, Dirac, Einstein and Hawking etc. and discussing concepts with professors, teachers and former CERN members. In adherence with Newtonian physics which is discussing aspects of interactions that can be seen and repeated, Walsh has unified gravity with quantum field theory, presents quantum verifications in Layman's terms and unites gravity with spacetime. The final piece of scientific literature of Newton's three laws of motion in relation to gravity and the grand unification of energy. The ""Holy grail"" of physics is within this book, physics confirms this."
