DeLorean time machine DeLorean time machine The DeLorean time machine is a fictional automobile-based time travel device featured in the "Back to the Future" franchise. In the feature film series, Dr. Emmett Brown builds a time machine based on a DeLorean DMC-12 car, to gain insights into history and the future. Instead, he ends up using it to travel over 30 years of Hill Valley history (from 1985 to 2015) with Marty McFly to change the past for the better and to undo the negative effects of time travel. One of the cars used in filming is on display at Universal Studios Hollywood
Time travel Mitchell's story 'The Clock That Went Backward' (1881) is usually described as the first time-machine story, but I'm not sure that a clock quite counts." H. G. Wells's "The Time Machine" (1895) popularized the concept of time travel by mechanical means. Some theories, most notably special and general relativity, suggest that suitable geometries of spacetime or specific types of motion in space might allow time travel into the past and future if these geometries or motions were possible. In technical papers, physicists discuss the possibility of closed timelike curves, which are world lines that form closed loops in spacetime, allowing
