About the book: 1987 / The book tells about the key problems of the modern physical picture of the world: about black and white holes in the Universe, about the “lovely”, “ flavored" and "colored" particles - quarks, about cosmic worlds hidden inside particles, about emptiness, which turns out to be not emptiness, but a material substance, about space quanta and time quanta, about hypothetical monopoles and antimatter. For a wide range of readers.
