In the original time travel novel, The Time Machine by HG Wells, the main character is sent on an extraordinary journey to the future. During this 800,000-year journey, the time traveler, as he is called in the book, faces many new challenges and discovers many new sites. Along with this fictional story, time travel becomes a new subject of study. Time travel, a theory supported by many world-renowned physicists, is a widely debated topic in modern times. However, to fully understand this debate, a small lesson is necessary. The intricacies of the theory of how time travel works are not considered common knowledge. One of the easiest concepts to understand is paradoxes. This concept is described as an argument whose outcome does not seem possible with the initial proposition (Lycan 1). Paradox is one of the main foundations of both sides of the debate. A seemingly more difficult concept, that of parallel universes, is defined as the theory that instead of a singular universe, multiple universes exist and that everything is copied in each of them (Wolf 101). This theory opposes the idea that only one universe exists. Following these narrow concepts, an overview of the theory of general relativity, a broad subject, is also necessary to understand time travel. This was proposed by Einstein and stated that the presence of matter would cause spacetime around it to distort (Kenyon 1). Next comes the theory of special relativity which explains how something that looks at time around it, while moving, distinguishes the time that has passed between two events (Davies). These are two integral theories that help both sides defend themselves. The most difficult concept to master in the study of time travel is that of closed time curves. These curves are common...... middle of paper ...... l-World relativity: the GPS navigation system. Ohio State University. Np, April 27, 2009. Web. June 9, 2010.
