Space & Extraterrestrial Theories

On the night of 11 October 1973, shipyard workers Charles Hickson (42) and Calvin Parker (19) claimed they were abducted from the banks of the Pascagoula River in Mississippi by three robotic beings who transported them aboard an oval craft for a medical examination. Sheriff James Caldwell, after interviewing the men, left them alone in a room with a hidden recorder — neither man broke their story when unobserved. Hickson subsequently passed a polygraph. No physical evidence of the encounter has been produced. The case remains one of the most-cited close-encounter reports but has no corroborating physical evidence.

On 30 June 1908, a massive explosion flattened approximately 2,150 square kilometres of Siberian taiga near the Podkamennaya Tunguska River. The blast, estimated at 10-15 megatons TNT equivalent, left no impact crater. Conspiracy framings — most notably that the explosion was caused by a weapon devised by Nikola Tesla — have circulated since the mid-twentieth century. Scientific investigations from 1961 through 2013, including the Anfinogenov sphere findings and Kvasnytsya nanodiamond paper, are consistent with an asteroid or comet air burst. The Tesla-weapon hypothesis has no evidentiary basis.

On 5 November 1975, 22-year-old Travis Walton claimed he was struck by a beam of light from a UFO and taken aboard a craft while six logging crew members watched near Apache-Sitgreaves National Forest, Arizona. Walton was missing for five days. The crew initially became suspects in his disappearance. When Walton reappeared, he described an encounter with humanoid beings aboard the craft. Multiple polygraph tests were administered to crew members and Walton over subsequent years, with contested and contradictory results. The case was dramatised in the 1993 film Fire in the Sky. No physical evidence has been produced.

A persistent Moon Landing Hoax sub-theory claims that director Stanley Kubrick filmed fake Apollo mission footage on a soundstage — often citing his 1968 film *2001: A Space Odyssey* as proof of his technical capability. Multiple independent lines of evidence refute the claim. The sustained low-gravity movement shown in Apollo footage (1/6 g for hours at a time) was technically impossible to simulate with 1960s film technology; *2001* itself used techniques that would have been immediately identifiable if applied to Apollo footage. The Soviet Union, tracking the missions and with every incentive to expose a fake, confirmed the missions. The Apollo program returned 842 lbs of lunar samples distributed to international labs. Lunar Reconnaissance Orbiter photographs from 2009 onward show Apollo landing sites with hardware and tracks still visible.

A common sub-theory of the Moon Landing Hoax claim holds that the Van Allen radiation belts surrounding Earth make a crewed lunar mission impossible — that astronauts would have received a lethal radiation dose before even reaching the Moon. The scientific record contradicts this. NASA engineered the Apollo trajectory to minimise belt exposure, reducing transit time to roughly one hour each way through the most intense zones. Total measured doses across the missions were well within established safe limits. The physicist who discovered the belts, James Van Allen, explicitly endorsed the Apollo missions and rejected the radiation-impossibility claim.

Claims that Artemis II mission photos, videos, or broadcasts prove the lunar flyby was staged or AI-generated.

A media-provenance page tracing alien-autopsy film and image claims.

Claims that a hidden planet is approaching Earth and repeatedly predicted to cause apocalypse.

Claims that mummified remains promoted from Peru are non-human alien bodies.

Claims that NASA or governments will fake an alien or religious event using holograms to create world government.

The claim, based on a 1984 packet of allegedly leaked documents, that President Truman in 1947 established a secret committee (Majestic 12 or MJ-12) of 12 scientists and military officers to study recovered UFO craft from Roswell.

The theory that NASA faked the Apollo moon landings between 1969 and 1972, filming them on a secret movie set rather than actually sending astronauts to the lunar surface.
