Time travel is the concept of movement (often by a human) between different points in time in a manner analogous to moving between different points in space, typically using a hypothetical device known as a time machine.on-technological forms of time travel had appeared in a number of earlier stories such as Charles Dickens ' A Christmas Carol. Historically, the concept dates back to the early mythologies of Hinduism (such as the Mahabharata).
Time travel â moving between different points in time â has been a popular topic for science fiction for decades. Franchises ranging from Doctor Who to Star Trek to Back to the Future have seen humans get in a vehicle of some sort and arrive in the past or future, ready to take on new adventures.The reality, however, is more muddled. Not all scientists believe that time travel is possible.dvances in quantum theories could perhaps provide some understanding of how to overcome time travel paradoxes. One possibility, although it would not necessarily lead to time travel, is solving the mystery of how certain particles can communicate instantaneously with each other faster than the speed of light.
