In clear, nontechnical language, string theorist Brian Greene explains how our understanding of the universe has evolved from Einstein's notions of gravity and space-time to superstring theory, where minuscule strands of energy vibrating in 11 dimensions create every particle and force in the universe. (This mind-bending theory has been testing at the Large Hadron Collider in Geneva).
This definition of 3 is found in many religions 3x3 and physics. Physics professor Brian Greene of Columbia, explains it so beautifully for everyday people "The Elegant Universe" The # is 9. In quantum mechanics a particle holds 3 to balance itself, but itself needs balancing w/2 other 3s. Neutron, Positron & Electron, 1 unit. Their mass equals them out in power. Need 2 more to keep the balance to work, how Universe runs on quantum rules. Feng Shui 9 is the real kicker.
