Time travel is a fascinating concept that has long captured the imagination of scientists, authors and filmmakers alike. It's the idea that you can travel into the past or future to change events or influence destiny. But what is time travel and how is it possible? In this essay, we will address these questions and try to get a clear idea of what time travel is and how it might work. The term time travel refers to the idea that you can move from one point in the space-time continuum to another without following the normal flow of time.
