The author, a world-famous ophthalmologist and traveler, shares in this book his discovery - the law of “four sixes”, which our planet obeys. The author comes to the conclusion that during apocalypses, the Earth’s axis rotates 6666 km, “shaking off” lost humanity from its surface. Moreover, it turns out that the main ancient monuments and mysterious places of the planet are also 6666 km apart from each other. Mathematical calculations are given, from which it is clear that ancient people not only knew about the law of “four sixes”, but also used the power of the “6666” points of the Earth for their lives. The book is written for a wide range of readers, although in essence it is deeply scientific.1- e edition, supplemented.
