The family of three, Antoine, Jerri, and son Terry, came across a small metal sphere the size of a bowling ball. Their first thought was the sphere had been a cannonball left from New World conquistadors. They decided to take the sphere back to their house. +Several days later, Terry was playing the guitar in their home. The sphere seemed to react to the sound of the guitar. It made a throbbing noise. Later, the sphere was noticed to roll on its own and even stop on its own and change direction. Terry started doing experiments with the sphere. He noticed the sphere would reverberate when hit with a hammer. He also found the sphere would move after being shaken and placed on the ground. +The Betzes reported that the sphere moved on its own several times, and that it would follow people around the house seemingly on its own. Eventually, they stored the sphere in a trunk, and only took it out to show friends and family. + + +== Analysis == + + +=== At the time of discovery === +In April 1974, United Press International (UPI) reported "The [United States] Navy said the sphere is nothing more than a huge ball bearing used as a check valve in the piping system of some chemical plant." The same month, the Miami Herald reported that a similar ball in Jacksonville (near Fort George Island) had been identified as "part of a valve once used in a paper mill." +In June 1974, UPI further reported that the sphere had been examined by a group of scientists attending a conference sponsored by the National Enquirer—the group felt "the object was constructed of some type of stainless steel made on earth." At the time, the National Enquirer was offering a cash reward for any object proven to have come from outer space. + + +=== Later review === +A 2012 analysis by Skeptoid revealed contemporary media analysis indicating that the Betz sphere may have been a ball check valve produced by the Bell & Howell company: its size, weight, and metallurgical composition matched those of the company's ball check valve. +Skeptoid also posited an explanation for the sphere's autonomous motion, noting that the sphere "sat quietly on display inside the Betz home for nearly two weeks, and is not reported to have ever moved on its own at all, except for when someone took it down to experiment with it", and quoting a representative of the U.S. Navy who stated that "I believe it's because of the construction of the house... It's old and has uneven stone floors. The ball is almost perfectly balanced, and it takes just a little indentation to make it move or change direction." +Skeptoid noted coverage of New Mexico artist James Durling-Jones, who had been collecting scrap metal for use in sculptures; Durling-Jones reported having loaded ball check valves into the rooftop luggage rack of his Volkswagen Bus, and having "(driven) through the Jacksonville area around Easter of 1971, at which time a few of the balls rolled off the luggage rack and were lost." Skeptoid concluded that this was the sphere's origin. + + +== See also == +Gravity hill – Illusion in which objects appear to roll uphill +Klerksdorp sphere – Natural nodule-like rock concretions +Stone spheres of Costa Rica – National symbol of Costa Rica + + +== Notes == + + +== References == + + +== External links == + +The Mysterious Betz Sphere of Fort George Island, The Jaxson \ No newline at end of file diff --git a/data/en.wikipedia.org/wiki/CERN_ritual_hoax-0.md b/data/en.wikipedia.org/wiki/CERN_ritual_hoax-0.md index b936f0fd8..293ea07e8 100644 --- a/data/en.wikipedia.org/wiki/CERN_ritual_hoax-0.md +++ b/data/en.wikipedia.org/wiki/CERN_ritual_hoax-0.md @@ -4,7 +4,7 @@ chunk: 1/1 source: "https://en.wikipedia.org/wiki/CERN_ritual_hoax" category: "reference" tags: "science, encyclopedia" -date_saved: "2026-05-05T04:31:00.092680+00:00" +date_saved: "2026-05-05T04:39:46.497322+00:00" instance: "kb-cron" --- diff --git a/data/en.wikipedia.org/wiki/Chemtrail_conspiracy_theory-0.md b/data/en.wikipedia.org/wiki/Chemtrail_conspiracy_theory-0.md new file mode 100644 index 000000000..ac4150fb0 --- /dev/null +++ b/data/en.wikipedia.org/wiki/Chemtrail_conspiracy_theory-0.md @@ -0,0 +1,27 @@ +--- +title: "Chemtrail conspiracy theory" +chunk: 1/3 +source: "https://en.wikipedia.org/wiki/Chemtrail_conspiracy_theory" +category: "reference" +tags: "science, encyclopedia" +date_saved: "2026-05-05T04:39:47.833953+00:00" +instance: "kb-cron" +--- + +The chemtrail conspiracy theory is the erroneous belief that long-lasting condensation trails left in the sky by high-flying aircraft are actually "chemtrails" consisting of chemical or biological agents, sprayed for nefarious purposes undisclosed to the general public. Believers in this conspiracy theory say that while normal contrails dissipate relatively quickly, contrails that linger must contain additional substances. Those who subscribe to the theory speculate that the purpose of the chemical release may be solar radiation management, weather modification, psychological manipulation, human population control, biological or chemical warfare, or testing of biological or chemical agents on a population, and that the trails are causing respiratory illnesses and other health problems. +Chemtrail conspiracy theories emerged in the late 1990s after publication of a 1996 United States Air Force (USAF) report on weather modification, with the Air Force accused of secretly spraying substances via aircraft. The theories spread through internet forums and were popularised by radio host Art Bell from 1999. +Chemtrails have been dismissed by the scientific community. There is no evidence that purported chemtrails differ from normal water-based contrails routinely left by high-flying aircraft under certain atmospheric conditions. Proponents have tried to prove that chemical spraying occurs, but their analyses have been flawed or based on misconceptions. Because of the conspiracy theory's persistence and questions about government involvement, scientists and government agencies around the world have repeatedly explained that the supposed chemtrails are in fact normal contrails. + +== History == + +Chemtrail conspiracy theories began to circulate after the United States Air Force (USAF) published a 1996 report about weather modification. In the late 1990s, the USAF was accused of "spraying the U.S. population with mysterious substances" from aircraft "generating unusual contrail patterns". The theories were posted on internet forums by people including Richard Finke and William Thomas and were among many conspiracy theories popularized by late-night radio host Art Bell, starting in 1999. As the chemtrail conspiracy theory spread, federal officials were flooded with angry calls and letters. +A multi-agency response attempting to dispel the rumors was published in 2000 by the Environmental Protection Agency (EPA), the Federal Aviation Administration (FAA), the National Aeronautics and Space Administration (NASA) and the National Oceanic and Atmospheric Administration (NOAA). Many chemtrail believers interpreted agency fact sheets as further evidence of the existence of a government cover-up. The EPA refreshed its posting in 2015. +In the early 2000s, the USAF released an undated fact sheet that stated the conspiracy theories were a hoax fueled in part by citations to a 1996 strategy paper drafted within their Air University titled Weather as a Force Multiplier: Owning the Weather in 2025. The paper was presented in response to a military directive to outline a future strategic weather modification system for the purpose of maintaining the United States' military dominance in the year 2025, and identified as "fictional representations of future situations/scenarios". The USAF further clarified in 2005 that the paper "does not reflect current military policy, practice, or capability" and that it is "not conducting any weather modification experiments or programs and has no plans to do so in the future". Additionally, the USAF states that the "'chemtrail' hoax has been investigated and refuted by many established and accredited universities, scientific organizations, and major media publications". +The conspiracy theories are seldom covered by the mainstream media, and when they are, they are usually cast as an example of anti-government paranoia. For example, in 2013, when it was made public that the CIA, NASA, and NOAA intended to provide funds to the National Academy of Sciences to conduct research into methods to counteract global warming with geoengineering, an article in the International Business Times anticipated that "the idea of any government agency looking at ways to control, or manipulate, the weather will be met with scrutiny and fears of a malign conspirac[y]", and mentioned chemtrail conspiracy theories as an example. Robert F. Kennedy Jr, United States Secretary of Health and Human Services since 2025, started supporting the conspiracy theory in 2024. +The conspiracy theory has inspired attempts at legislation in several US states. Some states, including Florida, have passed such laws. The Missouri Law Review discussed possibilities to regulate chemtrail misinformation legally in a 2020 article. + +== Description == +Proponents of the chemtrail conspiracy theory find support for their theories in their interpretations of sky phenomena, videos posted to the internet, and reports about government programs; they also have certain beliefs about the goals of the alleged conspiracy and the effects of its alleged efforts and generally take certain actions based on those beliefs. +The term chemtrail is a portmanteau of the words chemical and trail, just as contrail blends condensation and trail. + +=== Interpretation of evidence === \ No newline at end of file diff --git a/data/en.wikipedia.org/wiki/Chemtrail_conspiracy_theory-1.md b/data/en.wikipedia.org/wiki/Chemtrail_conspiracy_theory-1.md new file mode 100644 index 000000000..32a1b7426 --- /dev/null +++ b/data/en.wikipedia.org/wiki/Chemtrail_conspiracy_theory-1.md @@ -0,0 +1,27 @@ +--- +title: "Chemtrail conspiracy theory" +chunk: 2/3 +source: "https://en.wikipedia.org/wiki/Chemtrail_conspiracy_theory" +category: "reference" +tags: "science, encyclopedia" +date_saved: "2026-05-05T04:39:47.833953+00:00" +instance: "kb-cron" +--- + +Proponents of the chemtrail conspiracy theory say that chemtrails can be distinguished from contrails by their long duration, asserting that the chemtrails are those trails left by aircraft that persist for as much as a half-day or transform into cirrus-like clouds. The proponents claim that after 1995, contrails had a different chemical composition and lasted a lot longer in the sky; proponents fail to acknowledge evidence of long-lasting contrails shown in World War II–era photographs. +Proponents characterize contrails as streams that persist for hours and that, with their criss-cross, grid-like, or parallel stripe patterns, eventually blend to form large clouds. Proponents view the presence of visible color spectra in the streams, unusual concentrations of sky tracks in a single area, or lingering tracks left by unmarked or military airplanes flying atypical altitudes or locations as markers of chemtrails. +Photographs of barrels installed in the passenger space of an aircraft for flight test purposes have been claimed to show aerosol dispersion systems. The barrels' actual purpose is to simulate the weight of passengers or cargo. The barrels are filled with water, and the water can be pumped from barrel to barrel to test different centers of gravity while the aircraft is in flight. +Former CIA employee and whistleblower Edward Snowden, interviewed on The Joe Rogan Experience, said he had searched through all the secret information of the U.S. government for evidence about (aliens and) chemtrails. According to a CNN report about the webcast, he said: "In case you were wondering: ... Chemtrails are not a thing" and "I had ridiculous access to the networks of the NSA, the CIA, the military, all these groups. I couldn't find anything". +Jim Marrs has cited a 2007 Louisiana television station report as evidence for chemtrails. In the report, the air underneath a crosshatch of supposed chemtrails was measured and apparently found to contain unsafe levels of barium: at 6.8 parts per million, three times the nationally recommended limit. But a subsequent analysis of the footage showed that the equipment had been misused and the reading exaggerated by a factor of 100—the true level of barium measured was both usual and safe. +In 2014, a video that went viral showed a commercial passenger airplane landing on a foggy night, which was described as emitting chemtrails. Discovery News pointed out that passengers sitting behind the wings would clearly see anything being sprayed, which would defeat any intent to be secretive, and that the purported chemical emission was normal air disruption caused by the wings, visible due to the fog. In that same year, in several photos of German chancellor Angela Merkel visiting the ILA Berlin Air Show, the water tanks next to her were falsely identified as toxic chemicals. +In October 2014, Englishman Chris Bovey filmed a video of a plane jettisoning fuel on a flight from Buenos Aires to London, which had to dump fuel to lighten its load for an emergency landing in São Paulo. The clip went viral on Facebook, with over three million views and more than 52,000 shares, cited as evidence of chemtrails. He later disclosed that the video post was done as a prank. +In some accounts, the chemicals are described as barium and aluminum salts, polymer fibers, thorium, or silicon carbide. +Chemtrail believers interpret the existence of cloud seeding programs and research into climate engineering as evidence of the conspiracy. + +=== Beliefs === +Various versions of the chemtrail conspiracy theory have been propagated via the internet and radio programs. There are websites dedicated to the conspiracy theory, and it is particularly favored by far-right groups because it fits well with a deep suspicion of the government. +A 2014 review of 20 chemtrail websites found that believers appeal to science in some of their arguments but do not believe what academic or government-employed scientists say; scientists and federal agencies have consistently denied that chemtrails exist, explaining the sky tracks are simply persistent contrails. The review also found that believers generally hold that chemtrails are evidence of a global conspiracy; they allege various goals which include profit (for example, manipulating futures prices, or making people sick to benefit drug companies), population control, or weapons testing (use of weather as a weapon, or testing bioweapons). One of these ideas is that clouds are being seeded with electrically conductive materials as part of a massive electromagnetic superweapons program based around the High Frequency Active Auroral Research Program (HAARP). +Believers say chemtrails are toxic; the 2014 review found that they generally hold that every person is under attack and often express fear, anxiety, sadness, and anger about this. A 2011 study of people from the US, Canada, and the UK found that 2.6% of the sample believed entirely in the conspiracy theory, and 14% believed it partially. An analysis of responses given to the 2016 Cooperative Congressional Election Study showed that 9% of the 36,000 respondents believed it was "completely true" that "the government has a secret program that uses airplanes to put harmful chemicals into the air" while a further 19% believed this was "somewhat true". +Chemtrail conspiracy theorists often describe their experience as being akin to a religious conversion experience. When they "wake up" and become "aware" of chemtrails, the experience motivates them to advocacy of various forms. For example, they often attend events and conferences on geoengineering, and have sent threats to academics working in geoengineering. +Some chemtrail believers adopt the notions of Wilhelm Reich, who devised a "cloudbuster" device from pipework. Reich claimed this device would influence weather and remove harmful energy from the atmosphere. Some chemtrail believers have built cloudbusters filled with crystals and metal filings, which are pointed at the sky in an attempt to clear it of chemtrails. +Chemtrail believers sometimes gather samples and have them tested, rather than rely on reports from government or academic laboratories, but their experiments are usually flawed; for example, collecting samples in jars with metal lids contaminates the sample and is not done in scientific testing. \ No newline at end of file diff --git a/data/en.wikipedia.org/wiki/Chemtrail_conspiracy_theory-2.md b/data/en.wikipedia.org/wiki/Chemtrail_conspiracy_theory-2.md new file mode 100644 index 000000000..91e6664b5 --- /dev/null +++ b/data/en.wikipedia.org/wiki/Chemtrail_conspiracy_theory-2.md @@ -0,0 +1,39 @@ +--- +title: "Chemtrail conspiracy theory" +chunk: 3/3 +source: "https://en.wikipedia.org/wiki/Chemtrail_conspiracy_theory" +category: "reference" +tags: "science, encyclopedia" +date_saved: "2026-05-05T04:39:47.833953+00:00" +instance: "kb-cron" +--- + +=== Incidents === +In 2001, in response to requests from constituents, U.S. Representative Dennis Kucinich introduced (but did not author) H.R. 2977 (107th), the Space Preservation Act of 2001, which would have permanently prohibited basing weapons in space, listing chemtrails as one of a number of "exotic weapons" that would be banned. Proponents have interpreted this explicit reference to chemtrails as official government acknowledgment of their existence. Skeptics noted that the bill in question also mentions "extraterrestrial weapons" and "environmental, climate, or tectonic weapons". The bill received an unfavorable evaluation from the United States Department of Defense and died in committee, with no mention of chemtrails appearing in the text of any of Kucinich's three subsequent failed attempts to enact a Space Preservation Act. +In 2003, in a response to a petition by concerned Canadian citizens that "chemicals used in aerial sprayings are adversely affecting the health of Canadians", the Government House Leader responded: "There is no substantiated evidence, scientific or otherwise, to support the allegation that there is high altitude spraying conducted in Canadian airspace. The term 'chemtrails' is a popularised expression, and there is no scientific evidence to support their existence." The House leader added, "it is our belief that the petitioners are seeing regular airplane condensation trails or contrails." +In 2005 in the United Kingdom, Elliot Morley, a Minister of State for the Department for Environment, Food and Rural Affairs was asked by David Drew, the Labour Party Member of Parliament for Stroud, "what research [the] Department has undertaken into the polluting effects of chemtrails for aircraft", and responded that "the Department is not researching into chemtrails from aircraft as they are not scientifically recognised phenomena", and that work was being conducted to understand "how contrails are formed and what effects they have on the atmosphere." +During the 2011–2017 California drought, some local politicians in Shasta County reacted credulously to conspiracy theories suggesting that weather-modifying chemtrails had caused the unusual weather conditions. + +== Contrails == + +Contrails, or condensation trails, are "streaks of condensed water vapor created in the air by an airplane or rocket at high altitudes". Fossil fuel combustion (as in piston and jet engines) produces carbon dioxide and water vapor and soot particulates that act as cloud condensation nuclei. At high altitudes, the air is very cold. Hot humid air from the engine exhaust mixes with the colder surrounding air, causing the water vapor to condense into droplets or ice crystals that form visible clouds. The rate at which contrails dissipate is entirely dependent on weather conditions. If the atmosphere is near saturation, the contrail may exist for some time. Conversely, if the atmosphere is dry, the contrail will dissipate quickly. + +It is well established by atmospheric scientists that contrails can persist for hours, and that it is normal for them to spread out into cirrus sheets. The different-sized ice crystals in contrails descend at different rates, which spreads the contrail vertically. Then the differential in wind speeds between altitudes (wind shear) results in the horizontal spreading of the contrail. This mechanism is similar to the formation of cirrus uncinus clouds. Contrails between 25,000 and 40,000 feet (7,600 and 12,200 m) can often merge into an "almost solid" interlaced sheet. Contrails can have a lateral spread of several kilometers, and given sufficient air traffic, it is possible for contrails to create an entirely overcast sky that increases the ice budget of individual contrails and persists for hours. + +Experts on atmospheric phenomena say that the characteristics attributed to chemtrails are simply features of contrails responding to diverse conditions in terms of sunlight, temperature, horizontal and vertical wind shear, and humidity levels present at the aircraft's altitude. In the US, the gridlike nature of the National Airspace System's flight lanes tends to cause crosshatched contrails, and in general it is hard to discern from the ground whether overlapping contrails are at similar altitudes or not. The jointly published fact sheet produced by NASA, the EPA, the FAA, and NOAA in 2000 in response to alarms over chemtrails details the science of contrail formation and outlines the known and potential impacts that contrails have on temperature and climate. The USAF produced a fact sheet that described these contrail phenomena as observed and analyzed since at least 1953. It also rebutted chemtrail theories more directly by identifying the theories as a hoax and disproving the existence of chemtrails. +Patrick Minnis, an atmospheric scientist with NASA's Langley Research Center, has said that logic does not dissuade most chemtrail proponents: "If you try to pin these people down and refute things, it's, 'Well, you're just part of the conspiracy'". +Analysis of the use of commercial aircraft tracks for climate engineering has shown them to be generally unsuitable. +Astronomer Bob Berman has characterized the chemtrail conspiracy theory as a classic example of failure to apply Occam's razor, writing in 2009 that instead of adopting the long-established "simple solution" that the trails consist of frozen water vapor, "the conspiracy web sites think the phenomenon started only a decade ago and involves an evil scheme in which 40,000 commercial pilots and air traffic controllers are in on the plot to poison their own children". +A 2016 survey of 77 atmospheric scientists concluded that "76 out of 77 (98.7%) of scientists that took part in this study said they had not encountered evidence of a [secret large-scale atmospheric program] (SLAP), and that the data cited as evidence could be explained through other factors, such as typical contrail formation and poor data sampling instructions presented on SLAP websites". + +== See also == + +== References == + +== Further reading == +Talbot, Margaret (30 August 2002).

This alleged coordinated effort aims to control the population and reduce genuine human interaction. Supporters of the theory claim that social bots were deliberately created to manipulate algorithms and enhance search results to influence consumers. Some proponents also accuse government agencies of using bots to shape public perception and opinions. +The dead Internet theory gained renewed interest following the AI boom that began in the 2020s, with large language model (LLM) chatbots and text-to-image models emerging as technologies that could theoretically drown out human-authored content on the web. In the time since, social media sites have seen a measured increase in bot activity, such as algorithmic feeds displaying low-quality AI slop at the expense of user-generated content. +Despite there being no evidence of a conspiracy, commentators have linked some aspects of the dead Internet theory to this rise in generative content across social media. Sources see the theory as having some amount of truth behind it, or as offering a potentially realistic prediction of the Internet's future. One source uses the term "Dead Internet" to describe spaces online that host generative content, explicitly dropping the word "theory". Within the academic literature, a "leaner" version of the theory has been discussed that focuses on core principles, and strips the conspiratorial elements. + +== Origins and spread == +Academic literature often struggles to document online subcultures and conspiracy theories, making the origins of the dead Internet theory difficult to precisely identify. The first post on the dead Internet theory is thought to have originated on the image board Wizardchan. In 2021, a post titled "Dead Internet Theory: Most Of The Internet Is Fake" was published onto the forum Agora Road's Macintosh Cafe esoteric board by a user named "IlluminatiPirate", claiming to be building on previous posts from the same board and from Wizardchan, and marking the term's spread beyond these initial imageboards. The conspiracy theory spread into online culture through widespread coverage on platforms such as YouTube, Reddit, and Twitter, where it was amplified by online communities and content creators. It gained more mainstream attention with a September 2021 article in The Atlantic titled Maybe You Missed It, but the Internet 'Died' Five Years Ago. This article has been widely cited by other articles on the topic. +In 2023, the dead Internet theory entered academic literature when a book published by the CRC Press included a definition of the dead Internet theory in its glossary, and in 2024, when an opinion piece titled Artificial influencers and the dead internet theory was published in the Curmudgeon Corner of AI & Society. The glossary definition discussed the full theory, while the opinion piece did not, focusing instead on AI-generated content and AI-driven Interactions. These two sources have been cited by other academic articles that discuss the topic. In 2026, a publication in Computer (magazine) built upon the AI & Society article by distinguishing between a "Leaner" version of the dead Internet theory, centered on the core evidence, and the "conspiracy-laden" full version. +The recent growth of interest in the dead Internet theory has been linked to increasing public awareness of bots, algorithmic content distribution, and advances in artificial intelligence. + +== Claims == + +The dead Internet theory has two main components: that organic human activity on the web has been displaced by bots and algorithmically curated search results, and that state actors are doing this in a coordinated effort to manipulate the human population. The first part of the theory is described as the main argument, and the second where the conspiracy portion begins. This first part, that bots create much of the content on the Internet and perhaps contribute more than organic human content, has been a concern for a while, with the original post by "IlluminatiPirate" citing the article "How Much of the Internet Is Fake? Turns Out, a Lot of It, Actually" in New York magazine. The dead Internet theory goes on to include that Google, and other search engines, are censoring the Web by filtering content that is not desirable by limiting what is indexed and presented in search results. While Google may suggest that there are millions of search results for a query, the results available to a user do not reflect that. This problem is exacerbated by the phenomenon known as link rot, which is caused when content at a website becomes unavailable, and all links to it on other sites break. This has led to the theory that Google is a Potemkin village, and the searchable Web is much smaller than we are led to believe. The dead Internet theory suggests that this is part of the conspiracy to limit users to curated, and potentially artificial, content online. + +The second half of the dead Internet theory builds on this observable phenomenon by proposing that the U.S. government, corporations, or other actors are intentionally limiting users to curated, and potentially artificial, AI-generated content, to manipulate the human population for a variety of reasons. In the original post, the idea that bots have displaced human content is described as the "setup", with the "thesis" of the theory itself focusing on the United States government being responsible for this, stating: The U.S. government is engaging in an artificial intelligence-powered gaslighting of the entire world population. + +=== "Weak" and "Strong" versions === +A 2025 chapter in the book Market-Oriented Disinformation Research described the theory as having a "weak" and "strong" version. The "weak" version of the theory asserts that there is a group of elites using bots to shape public discourse, while the "strong" version of the theory asserts that society itself collapsed because of some catastrophic event, and some entity (perhaps aliens or highly advanced artificial intelligence) is keeping people connected to the internet to disguise this reality. \ No newline at end of file diff --git a/data/en.wikipedia.org/wiki/Dead_Internet_theory-1.md b/data/en.wikipedia.org/wiki/Dead_Internet_theory-1.md new file mode 100644 index 000000000..e8a8733da --- /dev/null +++ b/data/en.wikipedia.org/wiki/Dead_Internet_theory-1.md @@ -0,0 +1,33 @@ +--- +title: "Dead Internet theory" +chunk: 2/4 +source: "https://en.wikipedia.org/wiki/Dead_Internet_theory" +category: "reference" +tags: "science, encyclopedia" +date_saved: "2026-05-05T04:39:49.078633+00:00" +instance: "kb-cron" +--- + +=== "Leaner" dead Internet theory === +In a 2026 article, Hal Berghel discussed what he called a "Leaner" dead Internet Theory, "stripped of paranoia, prejudice, politics and polemic." In this discussion, Berghel points to the 2025 publication in AI & Society by Yoshija Walter, and lists algorithmic generated content, Generative AI byproducts, the difficulty for some people to distingusish between this and human generated content, and the resulting mistrust and misinformation as the core of the dead Internet theory. Berghel laments that conspiracy theorists take these phenomena and to make implausible claims, while arguing that core criticisms should not be dismissed. + +== Expert view == +Caroline Busta, founder of the media platform New Models, was quoted in a 2021 article in The Atlantic calling much of the dead Internet theory a "paranoid fantasy", even if there are legitimate criticisms involving bot traffic and the integrity of the Internet, but she said she does agree with the "overarching idea". A 2021 Ouest-France article, which heavily referenced the 2021 article in The Atlantic, went on to compare the dead Internet theory to flat Earth and COVID-19 conspiracy theories. The article stated that even though bots do produce online content, the dead Internet theory is still not realistic. In 2023 in The New Atlantis, Robert Mariani called the theory a mix between a genuine conspiracy theory and a creepypasta. A 2023 book published by CRC Press discussed the dead Internet theory, specifically mentioning Google censoring the web. The book included an entry for the term in its glossary defining it as: + +The Dead Internet Theory is a conspiracy theory that suggests the Internet has died and that much of the content we see online is now artificially generated by AI to manipulate the world population. The theory raises concerns about the impact of AI on propaganda, art, and journalism. +A 2024 IFLScience article stated: + +Like all good conspiracy theories, the Dead Internet Theory takes a kernel of truth or agreed sentiment (that the internet is getting worse, and that bot activity is increasing) and twists it into something it isn't. +In 2024, "dead Internet theory" was sometimes used to refer to the observable increase in content generated via large language models (LLMs) such as ChatGPT appearing in popular Internet spaces without mention of the full theory. In a 2024 opinion column in AI & Society's "Curmudgeon Corner", Yoshija Walter stated that the once speculative theory is now observable with the introduction of AI generated content. In a 2025 article by Thomas Sommerer, this portion of the dead Internet theory is explored, with Sommerer citing Walter and calling the displacement of human generated content with artificial content "an inevitable event". Sommerer states the dead Internet theory is not scientific in nature, but reflects the public perception of the Internet. Another article in the Journal of Cancer Education discussed the impact of the perception of the dead Internet theory in online cancer support forums, specifically focusing on the psychological impact on patients who find that support is coming from an LLM and not a genuine human. The article cited both Walter and the CRC Press book when defining the dead internet theory, but did not mention the conspiracy aspect. The article also discussed the possible problems in training data for LLMs that could emerge from using AI-generated content to train the LLMs. In a 2025 paper, Roland Leikauf described the dead Internet theory as "pseudoscientific" while questioning if new AI tools would justify our fear that the theory might become reality. Leikauf cites Walter's 2024 publication for his definition of the dead Internet theory. In a chapter of the 2025 book Market-Oriented Disinformation Research, it states: + +What makes the Dead Internet a nameworthy conspiracy is that even though it is rooted in selective truths that are exaggerated or even taken to their logical extremes, it also draws attention to a legitimate problem. +In a 2025 interview with Time, linguist Adam Aleksic stated that the dead Internet theory "used to be a lunatic fringe conspiracy theory, but it's looking a lot more real". +In a 2026 paper published in Computer (magazine), Hal Berghel discusses a "leaner" version of the theory, without the conspiratorial elements, focusing on the core claims. In this paper he states: + +We must admit that some of the core principles of the DIT are convergent with our technical and historical experience. Unfortunately, the conspiracy theorists augment these very plausible observations with their own mix of biases and agendas that lead to implausibility and absurdity, which in turn leads to rejection. But it is a mistake of the first order to dismiss the core criticisms unequivocally. + +== Criticism == +The dead Internet theory has been cited by some as a conspiracy theory lacking credible evidence. While research has shown that automated bot accounts makeup a significant portion of internet traffic, experts emphasize that this provides no proof of a coordinated effort to replace human activity online. Critiques argue that the theory is based largely on unverified observation, such as perceived declines in content quality or repetitive online interactions, rather than verifiable data. Researchers also note that many forms of bot activity such as spam filtering, Denial-of-service attacks, and web scraping serve specific functions, sometimes maliciously, but do not indicate in any way that human participation on the internet is being replaced. +Researchers have also compared the dead Internet theory to other internet related conspiracy theories and note that these theories often stretch current trends, like artificial intelligence and increased bot activity, into speculative claims without using concrete evidence. + +== Evidence == \ No newline at end of file diff --git a/data/en.wikipedia.org/wiki/Dead_Internet_theory-2.md b/data/en.wikipedia.org/wiki/Dead_Internet_theory-2.md new file mode 100644 index 000000000..ba6c5bc56 --- /dev/null +++ b/data/en.wikipedia.org/wiki/Dead_Internet_theory-2.md @@ -0,0 +1,38 @@ +--- +title: "Dead Internet theory" +chunk: 3/4 +source: "https://en.wikipedia.org/wiki/Dead_Internet_theory" +category: "reference" +tags: "science, encyclopedia" +date_saved: "2026-05-05T04:39:49.078633+00:00" +instance: "kb-cron" +--- + +=== Bot traffic === +In 2016, the security firm Imperva released a report on bot traffic after examining over 16.7 billion visits to 100,000 randomly selected domains, and found that automated programs were responsible for 52% of web traffic. This report has been used as evidence in reports on the dead Internet theory. Imperva's report for 2023 found that 49.6% of Internet traffic was automated, a 2% rise from 2022, which was partly attributed to artificial intelligence models scraping the web for training content. A 2023 policy paper from the Institutul Diplomatic Român cited this increase in bot traffic as the basis for the dead Internet theory. + +=== Large language models === + +Generative pre-trained transformers (GPTs) are a class of large language models (LLMs) that employ artificial neural networks to produce human-like content. The first of these to be well known was developed by OpenAI. These models have created significant controversy. For example, Timothy Shoup of the Copenhagen Institute for Futures Studies said in 2022, "in the scenario where GPT-3 'gets loose', the Internet would be completely unrecognizable". He predicted that in such a scenario, 99% to 99.9% of content online might be AI-generated by 2025 to 2030. These predictions have been used as evidence for the dead Internet theory. +In 2024, Google reported that its search results were being inundated with websites that "feel like they were created for search engines instead of people". In correspondence with Gizmodo, a Google spokesperson acknowledged the role of generative AI in the rapid proliferation of such content and that it could displace more valuable human-made alternatives. Bots using LLMs are anticipated to increase the amount of spam, and run the risk of creating a situation where bots interacting with each other create "self-replicating prompts" that result in loops only human users could disrupt. In an article in AI & Society, Henrique Marcos discusses the possibility of LLMs impacting linguistic communities as they become more widespread in a scenario like the dead Internet theory. + +==== ChatGPT ==== +ChatGPT is an AI chatbot whose late 2022 release to the general public led journalists to call the dead Internet theory potentially more realistic than before. Before ChatGPT's release, the dead Internet theory mostly emphasized government organizations, corporations, and tech-literate individuals. ChatGPT gives the average Internet user access to large language models. This technology caused concern that the Internet would become filled with content created through the use of AI that would drown out organic human content. + +=== Facebook === + +In 2024, AI-generated images on Facebook, referred to as "AI slop", began going viral. Subjects of these AI-generated images included flight attendants, black children next to artwork they supposedly created, and various iterations of "Shrimp Jesus", depictions of Christ "meshed in various forms" with shrimp. Many of these posts had hundreds or even thousands of comments saying "Amen". The images were cited as an example of the Internet of the time having begun to feel "dead". Sommerer discussed Shrimp Jesus in detail within his article as a symbol to represent the shift in the Internet, specifically stating: + +Just as Jesus was supposedly the messenger for God, Shrimp Jesus is the messenger for the fatal system [we've] maneuvered ourselves into. Decoupled, proliferated, and in a state of exponential metastasis. +Facebook includes an option to provide AI-generated responses to group posts. Such responses appear if a user explicitly tags @MetaAI in a post, or if the post includes a question and no other users have responded to it within an hour. +In January 2025, interest renewed in the theory following statements from Meta on their plans to introduce new AI-powered autonomous accounts. Connor Hayes, vice-president of product for generative AI at Meta stated, "We expect these AIs to actually, over time, exist on our platforms, kind of in the same way that accounts do ... They'll have bios and profile pictures and be able to generate and share content powered by AI on the platform." These accounts were quickly removed. + +=== Reddit === + +In the past, the Reddit website allowed free access to its API and data, which allowed users to employ third-party moderation apps and train AI in human interaction. In 2023, the company moved to charge for access to its user dataset. Companies training AI are expected to continue to use this data for training future AI. As LLMs such as ChatGPT become available to the general public, they are increasingly being employed on Reddit by users and bot accounts. Professor Toby Walsh, a computer scientist at the University of New South Wales, said in an interview with Business Insider that training the next generation of AI on content created by previous generations could cause the content to suffer. University of South Florida professor John Licato compared this situation of AI-generated web content flooding Reddit to the dead Internet theory. + +=== Twitter === + +In 2020, several Twitter accounts started posting tweets starting with the phrase "I hate texting" followed by an alternative activity, such as "i hate texting i just want to hold ur hand", or "i hate texting just come live with me". These posts received tens of thousands of likes, many of which are suspected to be from bot accounts. Proponents of the dead Internet theory have used these accounts as an example. + +In September 2025, OpenAI CEO Sam Altman posted on Twitter (by then called X), bringing attention to the dead Internet theory. He stated that:i never took the dead internet theory that seriously but it seems like there are really a lot of LLM-run twitter accounts now. This post went viral and lead to discussion about the impact of generative AI on society at large, including online experience, human language, and education. \ No newline at end of file diff --git a/data/en.wikipedia.org/wiki/Dead_Internet_theory-3.md b/data/en.wikipedia.org/wiki/Dead_Internet_theory-3.md new file mode 100644 index 000000000..164765f4b --- /dev/null +++ b/data/en.wikipedia.org/wiki/Dead_Internet_theory-3.md @@ -0,0 +1,33 @@ +--- +title: "Dead Internet theory" +chunk: 4/4 +source: "https://en.wikipedia.org/wiki/Dead_Internet_theory" +category: "reference" +tags: "science, encyclopedia" +date_saved: "2026-05-05T04:39:49.078633+00:00" +instance: "kb-cron" +--- + +=== TikTok === +In 2024, TikTok began discussing offering the use of virtual influencers to advertising agencies.

YouTube engineers coined the term "the Inversion" to describe this phenomenon. YouTube bots and the fear of "the Inversion" were cited as support for the dead Internet theory in a thread on the Internet forum Melonland. + +=== SocialAI === +SocialAI, an app created on September 18, 2024, by Michael Sayman, was created with the full purpose of chatting with only AI bots without human interaction.

The term Fogvid-24 was popularised on platforms such as TikTok and X during a period of widespread fog in North America and the United Kingdom. Fact-checkers and meteorologists attributed the reports to ordinary foggy conditions, seasonal respiratory illness, and misinterpretation of visual effects under lights, noting there is no evidence that the fog was engineered or that it contained harmful agents. + + +== Background == +In late December 2024, dense fog and freezing fog were widely reported in parts of the United States and the United Kingdom, disrupting transport and prompting routine advisories. During the same period, posts and short videos circulated claiming the fog was unusually thick, smelled "chemical," or left people unwell shortly after exposure; commenters began referring to the phenomenon as Fogvid-24. + + +== Claims == + + +== Responses and expert commentary == +Meteorologists and public-health communicators state there is no evidence that the fog was engineered or toxic, and that winter fog is expected under certain synoptic conditions (e.g., high humidity at or near the dew point, light winds, temperature inversions). Commentaries also note that shining bright lights into fog makes water droplets and other airborne particles more visible, which can be misinterpreted as unusual "large particles". Agencies have previously clarified limits of weather modification and debunked claims that routine technologies can create or steer widespread events. + + +== Media coverage and online spread == +Coverage by national and digital outlets traced the rise of Fogvid-24 narratives from late December 2024, highlighting typical themes—bioweapons, drones, "smart dust"—and documenting official explanations and routine advisories. Podcasts and explainers from meteorologists also addressed the rumours and reviewed likely meteorological setups for the fog. + + +== Historical references used in narratives == +Advocates often cite mid-20th-century U.S. open-air biological tests as precedent. In 1950, the U.S. Navy conducted Operation Sea-Spray, dispersing Serratia marcescens over the San Francisco area to study vulnerability to attack: a programme now widely criticised. Historians and health authorities caution, however, that such history does not evidence contemporary engineered fog events. Operation Big Buzz (1955), a U.S. Army biological warfare test where millions of mosquitoes (carriers of diseases like yellow fever) were released over the Black neighborhood of Carver Village to study disease transmission, causing illnesses and raising ethical concerns. This was part of larger Cold War-era biological weapon tests, including spraying bacteria simulants in other cities and testing mosquito-borne disease potential in Savannah and Avon Park, Florida, in the mid-1950s Operation Big Buzz. + + +== See also == +Weather modification +Chemtrail conspiracy theory +Mass psychogenic illness +Conspiracy theories + + +== References == + + +== External links == +"Fact check: Debunking weather modification claims".

Marie Curie was the first woman to also receive the Nobel Prize in Chemistry in 1911, making her the first person to win two Nobel prizes and, as of 2023, the only person to be awarded two Nobel prizes in two different scientific categories. +Maria Goeppert Mayer became the second woman to win the prize in 1963, for the theoretical development of the nuclear shell model, a half of the prize shared with J. Hans D. Jensen (the other half given to Eugene Wigner). Donna Strickland shared half of the prize in 2018 with Gérard Mourou, for their work in chirped pulse amplification beginning in the 1980s (the other half given to Arthur Ashkin). Andrea Ghez was the fourth female Nobel laureate in 2020, she shared one half of the prize with Reinhard Genzel for the discovery of the supermassive compact object Sagittarius A* at the center of our galaxy (the other half given to Roger Penrose). In 2023, Anne L'Huillier shared the prize in equal parts with Pierre Agostini and Ferenc Krausz for their experimental contribution and development of attosecond physics. L'Huillier is the first female laureate to receive 1/3 of monetary award of the Nobel Prize in Physics (Curie, Goeppert–Mayer, Strickland and Ghez received 1/4). +Physicists and physicochemists that won a Nobel Prize in Chemistry include Marie Curie, Irène Joliot-Curie, daughter of Marie Curie, in 1935, and Dorothy Hodgkin in 1964. Nuclear physicist Rosalyn Sussman Yalow was the second female scientist to win the Nobel Prize in Physiology or Medicine in 1977 for the development of radioimmunoassays.
