Motion Mountain - Volume 6

This book is written for anybody who is intensely curious about nature andmotion.Have you ever asked: Why do people, animals, things, images and empty space move?The answer leads to many adventures, and this book presents one of the best of them: the search for a precise, unified and final description of all motion.
The wish to describe all motion is a large endeavour. Fortunately, this large endeavour can be structured in the simple diagramshown in Figure 1.The final and unified description of motion, the topic of this book, corresponds to the highest point in the diagram. Searching for this final and unified description is an old quest. In the following, I briefly summarize its history and then present an intriguing, though speculative solution to the riddle.
The search for the final, unified description of motion is a story of many surprises. For example, twentieth-century research has shown that there is a smallest distance in nature. Research has also shown that matter cannot be distinguished from empty space at those small distances. A last surprise dates from this century: particles and space are best described as made of strands, instead of little spheres or points. The present text explains how to reach these unexpected conclusions. In particular, quantum field theory, the standard model of particle physics, general relativity and cosmology are shown to follow from strands.The three gauge interactions, the three particle generations and the three dimensions of space turn out to be due to strands. In fact, all the open questions of twentieth-century physics about the foundations of motion, all the millennium issues, can be solved with the help of strands.
