In the Back to the Future movies, Dr Emmett Brown uses a DeLorian DMC-12 as a time machine which can travel both forwards and backwards through time. The closest real-life version of this classic car was the Soviet/Russian Mir Space Station. The most time dilation experienced by an individual is approximately 1/48th of a second, for Russian cosmonaut Sergei Krikalev. This is a direct consequence of the 803 days 9 hr 39 min he has spent in space. While in orbit, travelling at around 27,000 kph (17,000 mph), relative to everyone else, he has essentially "time travelled" a fraction of a second into the future. This is consistent with Albert Einstein's Theory of Special Relativity.
