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 text of the book was translated from the original language using an artificial intelligence program. For the most part, the translation of the text is of very high quality, but in some cases, due to the imperfection of the technology, there may be incorrect phrase translations in the text, as well as single words and expressions may not be translated.
