Will time travel ever be possible? The science behind the possibility.
A common theme in science fiction media, time travel is captivating. It’s defined by the late philosopher David Lewis in his essay “The Paradoxes of Time Travel” as “[involving] a discrepancy between time and space time. Any traveler departs and then arrives at his destination; the time elapsed from departure to arrival … is the duration of the journey.”
Time travel is usually understood by most as going back to a bygone era or jumping forward to a point in the future. But how much of the idea is based in reality? Is it possible to travel through time?
