What is time travel ? is it happened in real?​

Answer» <html><body><p><strong>Explanation:</strong></p><h3>Time travel is the concept of movement between certain points in time, analogous to movement between different points in space by an object or a person, typically with the use of 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. <a href="https://interviewquestions.tuteehub.com/tag/wells-17822" style="font-weight:bold;" target="_blank" title="Click to know more about WELLS">WELLS</a>'s 1895 novel The Time Machine.[1]</h3><p></p><h3>It is uncertain if time travel to the past is physically possible. Forward time travel, outside the usual sense of the perception of time, is an extensively observed phenomenon and well-understood within the framework of special relativity and general relativity. <a href="https://interviewquestions.tuteehub.com/tag/however-1032379" style="font-weight:bold;" target="_blank" title="Click to know more about HOWEVER">HOWEVER</a>, making one body advance or delay more than a few milliseconds compared to another body is not <a href="https://interviewquestions.tuteehub.com/tag/feasible-456850" style="font-weight:bold;" target="_blank" title="Click to know more about FEASIBLE">FEASIBLE</a> with current technology. As for backward time travel, it is possible to find solutions in general relativity that allow for it, such as a rotating <a href="https://interviewquestions.tuteehub.com/tag/black-898687" style="font-weight:bold;" target="_blank" title="Click to know more about BLACK">BLACK</a> hole.
