Some notable people have given recent public exposure to the hypothesis, such as retired NASA aerospace engineer Larry Lemke,[2] Wisconsin congressman Mike Gallagher,[3] and American filmmaker Steven Spielberg.
[4][5] The time-traveler hypothesis is considered extremely implausible by mainstream scholars[6] and is generally regarded as unorthodox even among fringe conspiracy theorists who argue that UFOs are extraterrestrial spacecraft or interdimensional phenomena.
[citation needed] The notion of time travel from the future to the past is thought to have been introduced for the first time in literature by French botanist and geologist Pierre Boitard in his popular 1861 book Paris avant les hommes (Paris before Men), featuring a man sent back to prehistoric Earth where he interacts with an ape-like ancestor,[7] A few years later, in 1887, Camille Flammarion published Lumen, a novel featuring an alien soul traveling through different worlds and historical periods.
Climate change,[13] the technological singularity, space travel and genetic enhancement have also been identified as potential factors capable of altering the evolution of humans in the future, leading to different transhuman and posthuman scenarios.
The modern UFO era began in the Summer of 1947, days after the United States announced plans to re-industrialize Germany over strenuous Soviet objection, sparking the Cold War.
His article was cited and analysed,[16] alongside evolutionary biologist Theodosius Dobzhansky’s similar view on the implausibility of the evolution of humanoid extraterrestrial life forms, in the famous 2014 collection of essays Archaeology, Anthropology and Interstellar Communication edited by astrobiologist Douglas Vakoch and published by NASA in 2014.
The article goes on linking Hoover's story to other alleged UFO sightings and UFO abduction accounts with similar statements and reports about aliens actually being "humans of the future who have found the technology to overcome the limitations of light speed and time travel paradoxes that keep present day humans from breaching the boundaries of time" and that their "often-humanoid appearance may suggest a link between the way we look today, and what we might look like thousands of years from now.
"[25] In his 2019 book Identified Flying Objects and subsequent 2022 volume The Extratempestrial Model, Dr Masters explored more in depth various aspects of the time-traveler hypothesis, including fringe ancient astronauts theories and possible future development scenarios of human anatomy such as brain growth, craniofacial evolution, bipedalism, paedomorphism and more.
[26][27][2][28][29][30][31][32] Masters and his theory were featured on various podcasts, such as Sean Patrick Hazlett's Through the Glass Darkly,[33] and The Cryptid Factor co-hosted by New Zealand journalist David Farrier, comedian Rhys Darby, producers Dan Schreiber and Leon Kirkbeck.
[27] The 1966 Sherwood Schwartz TV series It's About Time portrays 20th-century astronauts being sent back to the stone age after traveling around the earth faster than the speed of light.
In Gregory Benford’s 1980 novel Timescape, scientist Saul Shriffer, a colleague of Frank Drake at the SETI Project Ozma, believes that a cryptic signal is of extraterrestrial origin, when it fact it had been sent thirty-four years into the past by humans in the future.
In 1993, Syfy (at the time "Sci-Fi Channel") produced their first original TV film,[38] Official Denial, directed by Brian Trenchard-Smith and written by Bryce Zabel, in which a man named Paul Corliss, played by Parker Stevenson, is abducted by aliens who at the end of the movie are revealed to be humans from the future.
In the fifteenth comic book of the Belgian series Blake and Mortimer, The Strange Encounter (2001), British physicist Philip Mortimer and Dr. Walt Kaufman from SUFOS (section of UFO Studies) investigate the corpse Major Lachlan Macquarrie disappeared in the Battle of Saratoga in 1777 after the appearance of three mysterious lights and reappeared in the present under the same circumstances, wearing a baldric inscribed with the words "Yellow King, 8061, Danger, Light, Plutonian, H, Poplar trees, Temple 1954".
Based on the mysterious clue found on Major Macquarrie, they hypothesize that the alien could be from Pluto only to instantly realize that his physiology is unsuitable to survive the planet's harsh environment.
"[41] The 2014 movie Interstellar contains deus ex machina beings who built the tesseract environment inside the supermassive black hole Gargantua and possibly placed the wormhole near Saturn that will lead the crew of the Endurance to three potentially habitable exoplanets.
People in the ufology community, such as former MUFON director for the state of Pennsylvania John Ventre in an interview with KDKA News Radio,[44] as well as American parapsychologist and engineer Harold E. Puthoff,[45] refer to the two interchangeably.
[46] Indeed, from a more scientific standpoint – albeit controversially – within the framework of the many-worlds interpretation of quantum mechanics, temporal paradoxes could be avoided if the time traveler would move from one dimension, or parallel universe, or timeline, to another.
