I have a question about physics theory pertaining to the singularity beginning our particular universe. The laws physics may be thought of as “A logical explanation of the workings of our particular universe”. If you are going to accept that our universe is one of many others, how can you be sure that these laws will be applicable in a different universe? In the attempt to describe the origin of multiple “parallel universe's”, perhaps the origin of ours may be described. Under our accepted laws of physics, time is continuous and irreversible. Let me stray from my thinking to provide a necessary example to convey my thinking. Consider a truly irreversible chemical reaction. Consider the beginning of this reaction to be t=a. As the reaction proceeds, it will eventually stop at t=b. If it is possible to travel beyond the speed of light then theoretically it is possible to take an irreversible reaction from t=b to t=a, hence reversing the irreversible. In contrast, take the “big bang” to be t=a, and present time to be t=b. If it were possible to travel beyond the speed of light, then based on accepted theories it would be possible to travel from t=b to t=a. Furthermore, it would be possible to travel back further than the “big bang”. Since the “big bang” is accepted as the beginning of matter in our universe, you would have essentially brought matter to where matter doesn't exist. Logic dictates that this is not possible. How can something exist when it doesn't? Perhaps e=mc^2 does not describe the limits and principles of light, but rather the limits of our particular universe? Our particular existence can be described through three visible dimensions of length, width and height. Time, can be considered a dimension. What if time was in fact not a 4th dimension, but a “governing dimension” of our universe? What if the “natural speed limit” was best was to describe our universe? If it is accepting that there are multiple oscillating universes, then why can time not be a description of understandable, perceivable, tangible dimension but rather the oscillating limit of our universe? If there are parallel universes, could the limit of the speed of light be the line between our universe and another, parallel universe? Could the speed limit of light simply be line between our universe and the other universes?
