The Dulce Base: A Secret Human-Alien Underground Facility in New Mexico
The Dulce Base legend claims a multi-level, jointly-operated human-alien facility hides beneath Archuleta Mesa near Dulce, New Mexico, complete with genetic experiments, a 'Nightmare Hall,' and a 1979 firefight between aliens and human security. No physical evidence for any such base has ever surfaced. The story's documented origin is far stranger than the myth: a real U.S. Air Force disinformation campaign, run through AFOSI, that targeted Albuquerque businessman Paul Bennewitz and helped manufacture a modern UFO legend.

The Dogon and Sirius B: Did Amphibious Aliens Teach an African Tribe About an Invisible Star?
Robert Temple's 1976 book The Sirius Mystery claimed the Dogon people of Mali held impossible ancient knowledge of Sirius B, an invisible white-dwarf companion star with a ~50-year orbit, taught to them by amphibious extraterrestrials called the Nommo. The claim rests on 1930s-40s ethnography by Marcel Griaule and Germaine Dieterlen. But a 1991 field restudy by anthropologist Walter van Beek found Dogon informants did not actually hold the Sirius-B lore Griaule reported, Sirius B's existence and orbital period were already well known to Western science before Griaule arrived, and Carl Sagan and others argue the knowledge, if genuine, reached the Dogon through ordinary human contact.

Bitcoin Was Created by the NSA
The claim that Bitcoin was secretly built by the NSA (or another intelligence agency) as a surveillance tool, honeypot, or stepping stone to a controllable cashless currency. Proponents point to two real facts: the NSA designed the SHA-256 hash function Bitcoin uses, and NSA cryptographers co-authored a 1996 paper on anonymous electronic cash. But no evidence connects the agency to Bitcoin's creation, the technology it uses is public and standardized, and the code and history point to an independent cypherpunk lineage.

The Baghdad Battery: Ancient Electricity 2,000 Years Before Volta?
A set of clay jars with copper cylinders and iron rods, found near Baghdad and dated to the Parthian or Sasanian era, are claimed by alternative-history writers to be ancient electric batteries — proof of a lost electrical technology used for electroplating, or even a gift from ancient astronauts. The jars are genuinely old and a jar-plus-two-metals arrangement really can produce a fraction of a volt, and replicas (including a famous MythBusters build) have generated current. But there are no wires, no connectors, no electroplated artifacts, and no textual record of electricity in antiquity. The mainstream archaeological reading — storage vessels for sacred scrolls or protective spells — fits the evidence far better.

JFK Assassination: Second Shooter from the Grassy Knoll
The grassy knoll second-shooter claim is the most prominent sub-theory of the JFK assassination conspiracy. It holds that a second gunman fired from the wooden fence atop the grassy knoll north of Elm Street in Dealey Plaza on 22 November 1963. Evidence for the claim rests primarily on acoustic analysis of a Dictabelt police-radio recording (the basis for the HSCA 1979 conclusion of probable conspiracy), some witness testimony, and a perceived head-movement in the Zapruder film. The acoustic evidence was subsequently rejected by a National Research Council panel and the FBI. No physical evidence — no second bullet, no shell casings, no blood-spatter consistent with a frontal shot — has been produced. The Warren Commission found no credible second-shooter evidence; the HSCA concluded probable conspiracy based on the acoustic evidence; the NRC and FBI rejected that acoustic evidence. The claim is unsubstantiated but not fully resolvable.

New Jersey Drone Sightings 2024
In November–December 2024, a wave of unidentified drone sightings over New Jersey and surrounding states generated significant media and political attention. NJ Governor Phil Murphy, FBI, FAA, and DHS acknowledged the sightings but offered no definitive explanation. Multiple theories circulated: foreign-adversary surveillance, US military testing, hobbyist drones, misidentified aircraft. The FBI and DHS investigation concluded that many sightings were explained by misidentified commercial aircraft, hobbyist drones, and stars/planets. The "foreign adversary surveillance" and "advanced military testing" framings remain unsubstantiated.

GLP-1 / Ozempic Side-Effect Suppression Claims
GLP-1 receptor agonists (semaglutide/Ozempic/Wegovy, tirzepatide/Mounjaro) are the fastest-growing drug class of the 2020s. Real adverse event reports exist in FDA FAERS data — including thyroid concerns, pancreatitis, and suicidal ideation reports — and are publicly available. Large peer-reviewed clinical trials (NEJM SELECT 2023, SURMOUNT-1 2022) have found these side effects either absent at statistically significant levels or outweighed by cardiovascular benefit. The conspiracy claim that pharma is deliberately hiding life-threatening side effects contradicts the publicly available clinical-trial data and FDA post-market surveillance, which are accessible to any researcher.

DOGE and the Hidden Government Spending Claims
The Department of Government Efficiency (DOGE), created by executive order in January 2025 with Elon Musk as a senior advisory figure, identified real inefficiencies and duplicate payments in federal contracting. A conspiracy framing built on this foundation claims that DOGE uncovered explosive evidence of trillions in hidden slush funds or systemic fraud that is being suppressed by the deep state, congressional leadership, or the administrative bureaucracy. GAO and Inspector General reports confirm real but limited waste findings; the "suppression of explosive revelations" framing is unsubstantiated.

Marilyn Monroe Assassination
Marilyn Monroe died on August 4–5, 1962 at her Brentwood home. The Los Angeles County coroner ruled probable suicide by acute barbiturate poisoning. Persistent claims hold that she was murdered — by the CIA, FBI, or individuals connected to President Kennedy or Attorney General Robert Kennedy — to prevent her from disclosing sensitive information. The FBI surveillance file on Monroe is real. Multiple forensic re-examinations have not produced new evidence supporting the assassination claim, which remains unsubstantiated.

Antifa: Cult and Coordinated-Organization Claims
Two related conspiracy framings are commonly applied to "antifa" — a recent rhetorical "cult of antifa" framing, and the older claim that antifa is a centrally coordinated terror organisation. Both fit poorly with the documented reality of decentralised local antifascist affinity groups, no central leadership, no unified funding source, and no formal membership. Local affinity groups (Rose City Antifa, NYC Anti-Fascist Action) and specific protest violence are documented in court records; the larger "central cabal" and "high-control cult" claims are not. FBI Director Christopher Wray testified in September 2020 that antifa is "an ideology, not an organisation."

Yellowstone Supervolcano Cover-Up
Claims that the US government or USGS is concealing evidence of an imminent Yellowstone supervolcano eruption that would devastate North America, or that seismic and geothermal data are being misrepresented to prevent public panic. The USGS Yellowstone Volcano Observatory (YVO) publishes its monitoring data in real time. The current probability of a large-scale Yellowstone eruption in any given year is approximately 1 in 730,000.
