Grand Slam Theory of the Omniverse: What Happened before the Big Bang? is more than a theory of how the universe began. It is the realization of a larger reality from which its creation was made possible. It is the perception of a universal consciousness as it begins to awaken to its true surroundings. Our universe is rooted in a bigger reality, which it must overcome. As we shall see through our modern scientific context, this new model of something greater than the universe will help us solve the mysteries about our universe that we have sought throughout the ages. This is the Omniverse. Modern science has given us accurate predictions, precise mathematical theories, and countless observations to shape our view of the universe. Throughout the years, discoveries made were like pieces of a puzzle. Some of the latest pieces include the July 4, 2012 observations of the Higgs boson and dark matter. Like separate pieces of a puzzle, we shall see how each part fits together to complete the picture. The Omniverse is the big picture. It is the puzzle pieces arranged together to form the model. The model of the Omniverse is actually quite simple. It consists of a diagram small enough to write on a Post-it note. But what it means to us is huge. It is the universe's path to ascension, described as the Grand Slam. If our entire universe is just the size of a baseball, then picture the stadium, parking lots, and surrounding areas as higher dimensions of the Omniverse. The Omniverse is more than just a new scientific proposal. It is information that awakens us to greater surroundings followed by a new era of scientific discovery. This model will have us dropping assumptions of what humanity knows thus far and realizing infinite possibilities.
