The Piri Reis map is a genuine 1513 Ottoman world chart, one-third of which survives, that alternative-history writers claim depicts the coastline of Antarctica ice-free—proving a lost advanced or extraterrestrial civilization mapped the planet during the last Ice Age. Cartographic historians instead read the puzzling southern landmass as a distorted, wrapped rendering of South America's coast.

The recurring claim that polling stations hand out pencils so that the state, MI5, or a hidden 'establishment' can secretly rub out and rewrite votes. It is true that UK polling stations traditionally supply pencils and that voters may bring their own pen. But ballots are sealed, transported, and counted the same night under the direct scrutiny of candidates' agents and observers, no evidence of pencil-enabled vote-switching has ever been found, and election authorities across the UK, Canada, Australia and the US have repeatedly debunked the idea. Pencils are used for mundane practical reasons, not for tampering.

NESARA/GESARA is the belief that a secret law was passed that will cancel all debts, abolish the IRS, release vast hidden 'prosperity funds,' and revalue world currencies once it is finally 'announced.' It began as a real but never-introduced 1990s reform proposal that an internet writer transformed around 2000 into a conspiracy theory that has never once come true.

In 1976 NASA's Viking 1 orbiter photographed a mesa in the Cydonia region of Mars that, under low resolution and slanting sunlight, resembled a humanoid face. Fringe researchers argued it was an artificial monument built by a lost Martian civilization and that NASA covered up the truth, but higher-resolution imaging over the following decades resolved it into an ordinary eroded hill.

UN Agenda 21 (1992) and its successor the 2030 Agenda for Sustainable Development (2015, the 17 SDGs) are non-binding, voluntary UN action plans on sustainable development. A conspiracy theory recasts them as a covert blueprint for one-world government, abolition of private property, forced urbanization and depopulation.

The Black Knight satellite is the belief that an artificial object of extraterrestrial origin, roughly 13,000 years old, has been silently orbiting Earth in a near-polar orbit. In reality it is a single 'legend' assembled from at least six unrelated, individually explained events, capped by 1998 NASA photos of a lost thermal blanket.

On April 20 1999 Eric Harris (18) and Dylan Klebold (17) killed 13 people and injured 24 at Columbine High School, Littleton CO, before dying by suicide. Initial reporting — including a USA Today front page and a Time cover captioned 'The Monsters Next Door' — framed the pair as outcast goths bullied into revenge by peers. Dave Cullen's 2009 book 'Columbine' and FBI profiler Dwayne Fuselier's psychological analysis demolished that framing: Harris met criteria for clinical psychopathy on the Hare PCL-R scale; Klebold was severely depressed and suicidal; neither was a bullied loner in the sense the media narrative required. The 'Trench Coat Mafia' was a separate clique whose members had graduated before the attack; Harris and Klebold wore the dusters for tactical concealment, not group identity.

The Protocols of the Elders of Zion is an antisemitic forgery first published in the Russian newspaper Znamya in 1903 by Pavel Krushevan, with later editions promoted by Pyotr Rachkovsky of the Okhrana (Tsarist secret police). The text plagiarises Maurice Joly's 1864 satirical Dialogue aux Enfers (targeting Napoleon III) and elements of Hermann Goedsche's 1868 novel Biarritz. Times of London journalist Philip Graves documented the direct plagiarism in August 1921. Henry Ford serialised the text in the Dearborn Independent (1920–22). Swiss Bern Trial (1933–35) declared it a forgery, though overturned on technicality in 1937. The text has been used by the Hamas Charter (1988), Iranian state media, and white supremacist organisations. Verdict: debunked.

Robert F. Kennedy Jr. has promoted vaccine-autism and vaccine-injury claims since the early 2000s, founding the World Mercury Project (later Children's Health Defense) to advance those claims. The foundational vaccine-autism link derived from Andrew Wakefield's 1998 Lancet paper, retracted in 2010 after investigation found data fabrication and undisclosed financial conflicts; Wakefield was struck off the UK General Medical Council. The thimerosal-mercury hypothesis Kennedy championed was addressed by the 2004 IOM report and by Hviid et al. (2003, NEJM) among many subsequent studies, all finding no causal link. Kennedy was nominated as HHS Secretary in November 2024 and confirmed in 2025, bringing the claims into active US public health policy.

Over two nights in late December 1980, USAF airmen stationed at RAF Woodbridge and RAF Bentwaters in Suffolk reported encountering a landed or hovering unidentified craft in Rendlesham Forest. Lt Col Charles Halt later filed an official memo describing the incident, which was declassified via FOIA in 1983. Investigators Ian Ridpath and Kevin McClure subsequently identified mundane explanations: the Orfordness Lighthouse and the reentry of Soviet satellite Cosmos 749. The UK Ministry of Defence concluded in 2001 the event had 'no defence significance.' The incident is sometimes called 'Britain's Roswell.'

The Whitewater investigation concerned a 1978-1979 real-estate investment by Bill and Hillary Clinton in the Whitewater Development Corporation in Arkansas, linked to Madison Guaranty Savings and Loan run by James McDougal. Resolution Trust Corporation referrals in 1992 prompted independent counsel investigations: first under Robert Fiske (1994), then under Ken Starr from August 1994. The final report by Robert Ray in September 2000 found insufficient evidence to indict the Clintons. Susan and Jim McDougal and Arkansas Governor Jim Guy Tucker were convicted of unrelated fraud. The investigation's scope expanded dramatically into Monica Lewinsky, leading to Clinton's 1998 impeachment. The original Whitewater allegations against the Clintons are debunked; the surrounding political controversy is documented history.

On 13 July 2024, Thomas Matthew Crooks fired on a Trump campaign rally in Butler, Pennsylvania, grazing Trump's ear and killing audience member Corey Comperatore. Crooks was shot dead by counter-snipers. Secret Service Director Kimberly Cheatle resigned following congressional pressure. Senate HSGAC and a bipartisan House Task Force launched investigations. The inside-job framing — that security failures were deliberate — is not supported by FBI findings or congressional conclusions, which attribute failures to coordination breakdowns and resource shortfalls.

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 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.

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.

The battleship USS Maine sank in Havana Harbor on 15 February 1898, killing 266 sailors. The Sampson Court of Inquiry (1898) and the Vreeland Board (1911) both attributed the sinking to an external mine, fuelling the "Remember the Maine" war cry that helped launch the Spanish-American War. Admiral Hyman G. Rickover commissioned a 1976 Naval History and Heritage Command study concluding that a coal-bunker fire adjacent to a magazine was the most probable cause. Modern computational analysis (1998 National Geographic study) supported the coal-fire hypothesis. The Spanish-mine attribution is now considered the debunked framing by mainstream naval historians.

Grand Duchess Anastasia Nikolaevna of Russia was executed with the rest of the Romanov family by Bolshevik forces at Yekaterinburg on 17 July 1918. Uncertainty about whether all family members were killed — rooted in the chaotic disposal of the bodies — gave rise to multiple impostor claims over the following decades, most famously Anna Anderson, later identified by DNA as Franziska Schanzkowska of Poland. A partial grave was found in 1991 and confirmed five Romanovs by DNA; a second grave found in 2007 contained the remains of Alexei and one daughter, confirmed by DNA in 2008 and 2009. The full family is accounted for. No Romanov child survived.

Adolf Hitler died by suicide in his Führerbunker in Berlin on 30 April 1945. Soviet forces recovered remains; dental records matching Dr. Hugo Blaschke's records for Hitler were confirmed; the Soviet skull cap with a bullet hole was displayed as evidence. A persistent claim holds that Hitler escaped via ratlines to South America — Argentina is most frequently named. FBI files released under FOIA in 2014 reference wartime informant reports of Hitler sightings in Argentina; these are raw intelligence reports, not confirmed findings. The ratlines were real and transported genuine Nazi war criminals including Eichmann and Mengele. Hitler's death in the bunker is confirmed by multiple independent forensic and archival analyses.

On 26 March 1997, 39 members of the Heaven's Gate religious movement were found dead at a rented mansion in Rancho Santa Fe, California. They had ingested phenobarbital mixed with vodka and applied plastic bags to their heads. Leader Marshall Applewhite had taught that a spacecraft trailing comet Hale-Bopp would transport their souls to a higher realm. Claims of government cover-up or institutional concealment are unsupported: the investigation was transparent, Applewhite's videotaped teachings are publicly available, and the deaths were thoroughly documented.

In June 1998, CNN's NewsStand programme broadcast a report claiming that US Special Forces used sarin nerve agent during Operation Tailwind in Laos in September 1970, specifically to kill American defectors. CNN retracted the report in July 1998 after an independent review by First Amendment attorney Floyd Abrams found the claim was not supported by the evidence gathered. The two producers responsible were dismissed. Operation Tailwind itself was a real classified SOG mission; the sarin-on-defectors claim is the fabricated element, retracted by the news organisation that aired it.

Silicon Valley Bank (SVB) collapsed on 10 March 2023 in the second-largest US bank failure in history. Conspiracy claims attributed the failure to coordinated short-selling campaigns or deliberate destabilisation by financial actors. Federal Reserve, FDIC, and congressional investigations attributed the collapse to SVB's concentration of approximately $91 billion in long-duration mortgage-backed securities purchased at near-zero interest rates, which lost market value as rates rose. When SVB announced a $1.8 billion realised loss from selling securities on 9 March, a Twitter-accelerated bank run ensued. Short-seller conspiracy claims are unsupported.

R&B singer Aaliyah Dana Haughton and eight others died when a Cessna 402B crashed shortly after takeoff from Marsh Harbour Airport in the Bahamas on 25 August 2001. The National Transportation Safety Board investigation determined the probable cause was weight overload and the aircraft being piloted by Luis Morales III, who was not rated for the aircraft type and whose toxicology showed cocaine and alcohol. The claim that the crash was a cover-up or an orchestrated killing has no evidentiary basis and directly contradicts the NTSB findings.

Jahseh Dwayne Ricardo Onfroy (XXXTentacion) was shot and killed during a robbery outside a motorsports dealership in Deerfield Beach, Florida, on 18 June 2018. Four men were convicted of first-degree murder and armed robbery in October 2023: Dedrick Williams, Michael Boatwright, Trayvon Newsome, and Robert Allen. The prosecution established a robbery motive — the perpetrators targeted XXXTentacion for cash he was known to be carrying. The claim that a rival record label orchestrated the killing has no evidentiary basis and contradicts the conviction record.

Whitney Houston was found unresponsive in a bathtub at the Beverly Hilton Hotel on 11 February 2012 and pronounced dead at age 48. The Los Angeles County coroner ruled the cause of death accidental drowning with cocaine use and atherosclerotic heart disease as significant contributing conditions. Within hours of the announcement, online conspiracy communities advanced the claim that Houston had been an Illuminati 'sacrifice' — killed by the music industry or a shadowy elite cabal. The claim has no forensic, documentary, or testimonial basis.
