Im a beliver Hay Chee. The concept of parallel dimensions is not new - in fact, it's been hypothesized that they somehow exist due to matter-antimatter imbalance. Interdimensional portals are not new either.

Society neither recognizes nor sanctions a personal change that does not have its origin in the immediate environment. It is difficult to undergo a perceptual shift while maintaining a stranglehold on the status quo. Conversely, if the status quo should be altered dramatically, it is equally stressful to adjust one's perspective in tandem with the shifting environment.

Some say that we live in the third dimension. That is, we have length, depth and height. Others would add another dimension and call it motion, placing us in the fourth dimension. Mathematically, there is a strong argument for dimensions below and above us. A single point in space could be assigned the name of the zero dimension. That point, extended in a straight line to infinity in two opposite directions could be named the first dimension. That line, extended sideways on a single plane to infinity in two directions, could be assigned the name, second dimension. That plane, extended to infinity perpendicular to itself in two directions, could be called the third dimension. Movement within that dimension could be labeled the fourth dimension. By mathematical extrapolation, there could be a fifth dimension, a sixth, etc. Just how many dimensions are there? If our universe is infinite, could there be an infinite number of other worlds or dimensions, each being infinite in scope? It boggles the mind to think of not just infinity squared or cubed, but infinity to the infinith power!
