    Gravity and Quantum Mechanics in String Theory
    The unified framework that string theory presents is compelling. But its real attraction is the ability to ameliorate the hostilities between the gravitational force and quantum mechanics. Recall that the problem in merging general relativity and quantum mechanics turns up when the central tenet of the former—that space and time constitute a smoothly curving geometrical structure—confronts the essential feature of the latter—that everything in the universe, including the fabric of space and time, undergoes quantum fluctuations that become increasingly turbulent when probed on smaller and smaller distance scales. On sub-Planck-scale distances, the quantum undulations are so violent
    (Epsilon=One: The term "violent undulations" is a poor description of the harmonious oscillations of all fundamental phenomena that act in syncopation coordinated by the beat of fundamental, intrinsic time (FIT).)
    that they destroy the notion of a smoothly curving geometrical space; this means that general relativity breaks down. (Epsilon=One: General Relativity (GR) breaks down on its own account. GR cannot account for accelerating, galactic expansion, or hyper-relativistic, cosmic entanglement. Nor, does GR or the Standard Model provide a logical theory for an accelerating force that is opposite to gravity that explains why Cosmic bodies hang in space—unsupported. The Big Bang is incomplete and ludicrous. For instance: What was the Big Bang within when it "banged"?)

    String theory softens the violent quantum undulations by "smearing" out the short-distance properties of space. There is a rough and a more precise answer to the question of what this really means and how it resolves the conflict. We discuss each in turn.
