क्या समय यात्रा सम्भव है ??? // Is time travel possible ??

there are some possible theories of time travel.
Time travel is commonly defined with David Lewis’ definition: An object time travels if and only if the difference between its departure and arrival times as measured in the surrounding world does not equal the duration of the journey undergone by the object. For example, Jane is a time traveler if she travels away from home in her spaceship for one hour as measured by her own clock on the ship but travels two hours as measured by the clock back home, assuming both clocks are functioning properly.
