One of the most popular topics in the history of science-fiction has been the idea of time travel. In literature and cinema, this topic has been exploited uncountable times. We know and love such works as H.G. Wells’ “Time Machine”; H.P. Lovecraft’s “The Shadow Out of Time”; Bradbury’s “A Sound of Thunder”; King’s “The Langoliers”; as well as numerous films and TV shows: “Back to the Future,” “Butterfly Effect,” and “Timecop.” These, as well as many others are dedicated mostly to one question: how can an individual affect or even change his or her entire life in the present by making even slight corrections in his or her own past? In my opinion, this is one of the most common, natural, and essential questions.
When I was a child, I often dreamed about a special pocket device that would allow me to “save” certain moments of my life, so that in case I failed to do something, I could always “load” my life from a checkpoint, already possessing a certain level of experience—exactly how they do it in video games. I imagined the things I could do if I had such power: jumping from skyscrapers without a parachute (and “loading” in the last second); traveling across savannas, jungles, and deserts; racing and performing other risky occupations. I especially liked to think about saving people from desperate and dangerous situations when others could not help; I guess every boy dreams of being a superhero, and I was no exception
