What is the Universe? How little is needed to describe it as an entity limited by the size and matter content. To describe on the basis of undoubtedly commonly known facts,and not on the basis of ad hoc assumptions,not based on theories whose scope of correctness is limited,not on the basis of dogmas,which already live their own lives. This book (volume one) is an introduction to a coherent description of the Universe and matter on all scales,also on the smallest scale of Planck.

It is a unique work, it is an unconventional book, and in its semantic point of view is sensational, in the full sense of the word. Already the first volume announces something unexpected for a traditional mainstream scientific narrative. This is a book about the Universe unlike anything that has ever been written. What is the Universe? How little is needed to describe it as an entity limited by the size and matter content. To describe on the basis of undoubtedly commonly known facts, and not on the basis of ad hoc assumptions, not based on theories whose scope of correctness is limited, not on the basis of dogmas, which already live their own lives. This book (volume one) is an introduction to a coherent description of the Universe and matter on all scales, also on the smallest scale of Planck. The starting point for this is the cosmological principle. The second pillar is the duality of gravity, discovered by the author. This work will surprise people of science - sooner or later, they will also decide to read it. So, reading this text is also not easy. “Can one man do so much alone?” Can he build from scratch, an alternative, internally coherent vision of the Universe, a falsifiable vision, easily answering many questions, to which science today has no answer? It turns out that yes. Not only this. There are also questions that have not yet been asked by science. The author answers some of them in a convincing way. So, this is not about a cheap advertising stunt. This is all true, even if it scares away professionals. The first volume of this work is a foretaste of a great intellectual adventure, it is an inspiring challenge - not only for people of science. Although this is a scientific work on the features of a philosophical dissertation, it is written in a popular language and is available to all those interested in Science, including young people. The author is a science writer (8 books), physicist, teacher, lecturer. He deals with the basics of physics and philosophical aspects of scientific research. Retired for many years.
