30 Famous Conspiracy Theories From the US

23. For years, people across Minnesota have reported hearing low humming or roaring sounds coming from the sky.

For years, cities across Minnesota have reported hearing strange humming noises that seem to come from the sky. In 2011, for example, many residents in Alexandria, Minnesota, caught on camera suspicious noises, bringing mainstream attention to the phenomenon, and sparked conspiracies. The theories were reintroduced in 2018 after another higher pitch sound was heard in Minneapolis.

Some blame it on the airplanes or the area having a high magnetic resonance, but others think the sounds are much more serious. They claim the sounds come from extraterrestrial beings or secret military testing or even a mind control weapon. It’s not just Minnesota that is experiencing this phenomenon. This steady, droning sound, commonly known as just ‘The Hum’, has also be reported in places as disparate as Taos, New Mexico, Bristol, England, and Largs, Scotland.

24. Conspiracy theories surround a mysterious New Hampshire formation known as Mystery Hill.

There is a 4,000-year-old archaeological site in Salem, New Hampshire, that no one has no idea how or why it was created. The site consists of chambers, walls, drains, and basins made of stone. Some people claim that the rock formation was formed by native Americans in the area or by colonial settlers.

As William Goodwin purchased the formations, he came up with the idea that the place was founded by Vikings or Irish monks long before Christopher Columbus arrived in the Americas. Some also believe the site dates back to medieval ages. Another famous theory is that the site was used as a stop on the underground railroad to hide former slaves.

25. Several people claim that the Joplin tornado was deliberately created by the military in 2011.

On May 22, 2011, at 5:41 p.m., Joplin, Missouri, was struck by a deadly tornado with winds approaching 200 mph. The tornado destroyed the city and killed 161 people. However, some of the out-of-this-world abilities of the tornado contributed to the development of conspiracy theories.

The most famous theory is that the tornado was created by one of our previous entries, the US Military at a facility in Alaska known as the High-Frequency Active Auroral Research Program (HAARP). The facility is researching the upper Earth’s atmosphere, but many believe that it can create hurricanes and tornadoes, much like the one in Joplin. Experts say this is an inaccurate theory, according to ABC News.

26. An abandoned ghost town in New Jersey became one of the first conspiracy theories of the Internet when people assumed the city was the site of a group that practiced interdimensional travel.

Ong ‘s Hat is a forgotten town in the Pine Barrens of New Jersey. The town dates from the 17th and 18th centuries, but the population decreased significantly in the 20th century, turning it into a ghost town. Many claim that the town was repopulated a few decades later. In the 1980s, a pamphlet was released stating that Ong ‘s Hat was home to a group of people who performed interdimensional travel.

The pamphlet suggested that the group started when two scientists from Princeton University moved to an abandoned town and eventually created “The Egg,” which enabled people to travel to alternate universes. According to the pamphlet, the computer was moving the entire group to a separate dimension in order to avoid police investigation. The theory has spread all over the internet. Although some people have suggested that they were part of this group at Ong ‘s Hat, there is no proof that this group ever existed. The most common theory is that Ong ‘s Hat is one of the earliest ARG’s (alternate reality game) a work of transmedia storytelling which is presented as fact.
