Time travel is the concept of movement between specific points in time, analogous to move between different points in space by an object or a person, typically using a hypothetical device known as a time machine. Time travel is a widely-recognized concept in philosophy and fiction. The idea of a time machine was popularized by H. G. Wells’ 1895 novel The Time Machine.
