That's it! No more mysteries! The deepest secrets of physical nature are now completely revealed! Did you ever wonder how everything came into existence? What is matter made of? What are, in fact, space and time, and why do elementary particles interact? And the one I like most: what is gravity and how does it exert its force throughout the Universe? Look no further: all the answers to these "big" questions are right here, put as simply as possible. No more hiding behind formulas and theories only a few can understand: now the naked truth comes in simple words that can easily describe our complex reality. This original, fascinating, paradigm-shifting theory unifies all of nature's fundamental forces into a single interaction, whose mechanics is based on space granularity - the only intrinsic characteristic of space physicists always avoided considering. The granular fabric of space actually makes possible the existence of matter and its continuous motion, which embeds relativity as a governing rule.
