This brochure is about a time machine, and not only about it, but more about physics and its capabilities in the study of such a complex concept as time. It turns out that you can look into the past today, and astronomers are successfully doing this by taking, for example, the light of a distant star that travels to us for billions of years. So how does physics look at the fundamental possibility of creating a time machine? How can it be arranged? The author of the issue talks about this in an interesting and very accessible form. The book’s text has been translated from the original language using an artificial intelligence system. In most cases, the translation is accurate and clear, but occasionally there may be incorrect phrasing or individual words left untranslated.
