" the Universe of Fluctuations "

We discuss a recent model of a Quantum Mechanical Black Hole (QMBH) which describes the most fundamental known particles the leptons and approximately the quarks in terms of the Kerr-Newman Black Hole with a naked singularity shielded by Zitterbewegung effects. This goes beyond the Zitterbewegung and self interaction models of Barut and Bracken, Hestenes, Chacko and others and provides a unified picture which amongst other things gives a rationale for and an insight into: 1. The apparently inexplicable reason why complex space time transformations lead to the Kerr-Newman metric in General Relativity. 2. The value of the fine structure constant. 3. The ratio between electromagnetic and gravitational interaction strengths. 4. The anomalous gyromagnetic ratio for the electron. 5. Why the neutrino is left handed. 6. Why the charge is discrete. In the spirit of Effective Field Theories, this model provides an alternative formalism for Quantum Theory and also for its combination with General Relativity. Finally a mechanism for the formation of these QMBH or particles is explored within the framework of Stochastic Electrodynamics, QED and Quantum Statistical Mechanics. The cosmological implications 0 International Journal of Modern Physics 'A' 1 are then examined. It turns out that a surprisingly large number of facts, including some which were hitherto inexplicable, follow as a consequence of the model. These include a theoretical deduction of the Mass, Radius and Age of the Universe, as also the values of Hubble's constant and the Cosmological constant.
