Scientists are actively engaged in understanding new observations regarding our universe. There is agreement that achieving a new level of understanding may require an extension to what is currently known about fundamental interactions, matter and energy. This book is a summary of work by the author building on the best measurements made by physicists, astronomers and cosmologists. Historically, a culture’s cosmology was an explanation of the origin and a justification for its most significant beliefs. Understanding nature’s language goes further. With it, we can read the book of nature and participate in the unfolding of nature’s potential. A no-nonsense engineering approach is used that simplifies nature to a few simple relationships. Of specific interest are the topics of force unification, gravitational theory and the definition of space and time. It also addresses several topics at the forefront of current research like dark energy and cold dark matter. Of course these are physical matters but the author addresses what this means to life and what it is reasonable to believe regarding philosophy’s “enduring questions”. Man invented language, developed an alphabet and then used the alphabet in creative ways to communicate. As a child we learn a language. It is an extremely useful tool but we didn’t invent the language. Physics is the same way. It has a language and an alphabet that it shapes into words and a significant story. One difference, however, is that we are one of the things it shapes and if we want to understand ourselves and the things around us we must learn the language. Nature starts with the whole, separates it into parts and then fits the parts together in different ways to make the universe we observe. This is a little like a picture puzzle. The picture is cut into pieces and then re-assembled. In the process, it becomes clear that the pieces are meant to fit together and the proof is simply that the picture is once again whole.
