This book describes the basic concept of the Universal Spacetime Theory (UST). During its development I was stimulated by many scientific ideas proposed since the dawn of science that I described briefly in Chapter 1. In the UST these ideas took on a completely new form thanks to my discovery of a spiral string entity that I named the toryx. The toryx turned out to be a perfect candidate for a prime element of nature. This however was only the tip of the iceberg. Besides yielding the unified laws applicable to both micro- and macro-worlds the toryx helped me to find the answer to the most puzzling question of science.
