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.
