While there are no documentaries on actual time travel experiences since time travel remains a theoretical concept, there are several documentaries that explore the topic of time travel or discuss the scientific theories behind it. Here are a few examples:
"How to Build a Time Machine" (2016): This documentary follows two men, Rob Niosi and Ronald Mallett, who are both fascinated by the idea of time travel. Niosi is constructing a full-scale replica of the time machine featured in the 1960 film "The Time Machine," while Mallett is a theoretical physicist working on a concept for a real time machine.
"The Fabric of the Cosmos" (2011): Although not solely focused on time travel, this documentary series, hosted by physicist Brian Greene, explores various concepts of space and time. One episode, titled "The Illusion of Time," delves into the nature of time, its perception, and how it relates to time travel.
"The World's First Time Machine" (2003): This documentary follows a team of scientists led by theoretical physicist Ronald Mallett, who is working on a real-world time machine based on Einstein's general theory of relativity. The film delves into Mallett's personal motivations and his scientific research.
"Parallel Worlds, Parallel Lives" (2007): This documentary is about Mark Oliver Everett, the lead singer of the band Eels, as he explores the life and work of his father, Hugh Everett III. Hugh Everett was a physicist who proposed the "Many-Worlds Interpretation" of quantum mechanics, which has implications for the possibility of time travel.
Please note that these documentaries may not provide a definitive answer on the practicality or feasibility of time travel, but they offer insights into the scientific theories and individuals exploring the subject.
