Antimatter is one of the favorite topics of science fiction writers. Nevertheless, it is real, and scientists have already learned how to obtain it. Matter and antimatter appeared as a result of the Big Bang in equal quantities. But matter remains, and there is no or almost no antimatter in our Universe. Why did this happen? What happened almost fourteen billion years ago? Are there other universes made of antimatter? How can antimatter be used on Earth? The author answers all these questions and talks about the great interest of various specialists in antimatter - as an alternative source of energy, as a possible fuel for intergalactic spaceships and as the basis of the most terrible weapon that humanity can invent.
