You've heard about how the moon landing was fake, how JFK's assassination was an inside job, and that a group of reptilian elites rule the world. But have you heard the theory that explains why Disney decided to go with Frozen for the name of its hugely successful animated flick? Or about that secret entrance into our hollow Earth? If not, buckle up.

Here, we present some of the wildest theories about Bigfoot, glitches in the Matrix, portals to alternate dimensions, and more.

Mermaids Roam the Deep Seas

Mermaids. Sirens. Aquatic apes. Whatever you prefer to call them, the idea that mermaids swam through the vast oceans has been alive and well among us for thousands of years. In fact, the conspiracy theory that mermaids are real and world governments know about them—but are keeping their existence a secret—still persists today. In 2012, the Discovery Channel released a mockumentary called Mermaids: The Body Found that set off a social media frenzy. There was some confusion about the veracity of the "documentary," but it was eventually revealed that the National Oceanic and Atmospheric Administration (NOAA) scientists were actually just paid actors. The real NOAA eventually released a statement saying that "no evidence of aquatic humanoids has ever been found."

Still, that hasn't stopped amateur web sleuths from trying to discover the mythical species of ocean-dwelling creatures. Even now, several TikTok users constantly share what they believe to be footage proving that mermaids are out there. One thing we know for certain is that there are several deep sea species that we haven't yet discovered—in fact, scientists estimate that a whopping 91 percent of ocean critters remain to be classified while 80+ percent of our oceans are "unmapped, unobserved, and unexplored." And for some, that's enough room for doubt that maybe, just maybe, mermaids could be among the great unknowns.

COVID-19 Was Engineered

There are so many COVID 19-related conspiracy theories that range from blaming 5G for the pandemic—which is still going strong, despite all of the scientific evidence—to condemning everyone from Big Pharma to Bill Gates for the outbreak.

There are also conspiracy theories that say COVID-19 doesn't even exist, and is simply being covered by the media to scare and control the masses. We must have missed the memo regarding that last one.

Here's the truth, plain and simple: These COVID conspiracies are patently false, and make light of a serious problem. The coronavirus is real and deadly. You can take steps that require minimum effort to protect yourself and others around you, like wearing a mask, frequently washing your hands with soap and water for a minimum of 20 seconds, and practicing social distancing.

CERN Helped End the World

Yes, as in, past tense. As in, the world ended in 2012 when CERN discovered the Higgs Boson (A.K.A. the God particle) and accidentally created a black hole that sucked Earth into it, and we just haven't really noticed yet.

There's a Twitter thread that dives deep into what might've happened in 2012, but as this video explains, it's not very likely that we've been sucked into an alternate black hole reality, since CERN doesn't have the ability to produce the amount of energy needed to create one.

And that's not the only conspiracy theory surrounding the European Organization for Nuclear Research (CERN)—a French acronym for Conseil Européen pour la Recherche Nucléaire. Another posits that CERN is planning to use the Large Hadron Collider to open a portal to hell. Or, that at the very least, the Collider is one of the seven seals of the apocalypse (which will also unleash hell on Earth).

The CERN acronym, in addition to a Shiva statue outside the facility, has led people to speculate that the scientists at CERN are actually trying to summon a God: either the Indian deity Shiva or Cernunnos, a Celtic deity who watches over the underworld (you know, because his name starts with Cern). And there are even more theories that say CERN is actually trying to access different timelines and experiment with time travel.

It sounds like CERN has its hands full.

Frozen: The Movie or Cryogenics?

What if we told you The Walt Disney Company created the movie Frozen to alter Google's search algorithm so that when people looked up some variation of "Disney Frozen," information about the movie—and not about Walt Disney himself being cryogenically frozen—would come up?

Screen Rant writes that cigarettes used to be cropped out of Disney's hands in an attempt to keep up with the Mouse House's family-friendly branding, so while creating a hit movie to mess with an internet algorithm sounds nutty, it kind of also makes sense.

And if it was intentional, Disney is full of geniuses.

Denver Airport is a Hub for the Illuminati

...And the New World Order (NWO). And it also acts as a gateway to hell. Who knew?

Conspiracy theorists posit that the Denver International Airport (DIA) is a hub for the lizard people who run the government and much of the world. (Just read our feature about it)

Some believe DIA is the home base of the Illuminati, while others believe it's actually a portal to hell, with Blucifer (the giant blue horse sculpture—which killed the artist who made it—with demonic, glowing red eyes) guarding the gateway.

There are the weird murals on the walls depicting Nazi imagery and a commemoration capstone plaque that mentions the New World Airport Commission (an organization that does not exist). Between that, the gargoyles in Jeppesen terminal, and the interactive gargoyle that welcomed travelers to the "Illuminati Headquarters" before correcting himself and welcoming the masses to "Denver International Airport," something weird seems to be going on there.

DIA is either poking fun at all the conspiracies surrounding the facility, or they're hiding in plain sight.

Hollow Earth

There's a conspiracy theory that says the Earth is hollow and that there might even be a whole other civilization of advanced beings living in it.

The theory is rooted back in the 17th century when Edmond Halley—who has a comet named after him—proposed that the Earth must be hollow due to changing magnetism.

In 2014, scientists found "a reservoir of water three times the volume of all the oceans" deep within Earth. The water, however, isn't just sloshing around within Earth—it's inside ringwoodite, a rock that's 435 miles deep beneath Earth's surface. For some, this bolstered the theory that Earth was hollow, since the water was solidified in rock form.

So how do you access this secret world within a world? Via secret entrances at either the North or South Pole, of course.

Bigfoot Is Real

Apparently, if Bigfoot does exist, the creature probably resides in Washington state. There have been 2,032 reported sightings as of May and there's even a list of the top eight states where you might catch a glimpse of him.

Then again, you might catch the fabled beast in Oregon, Pennsylvania, or Texas, since those states also have a high volume of reported sightings. Plus, Bigfoot has his own FBI file, so there's a good chance that something—or, as this news clip shows—several somethings are out there.

We're Living in the Matrix

Some conspiracy theorists believe that we live in a giant simulation, like in The Matrix. There's also a subreddit dedicated to glitches in the matrix where people share their weird experiences.

The stories are crazy and include people seeing the same "background character" across large spans of time, in random locations, who never seems to age due to people losing chunks and track of time.

Some respected thinkers believe that living in a simulation might be possible, but so far, it's just a far-fetched theory.

The Moon Doesn't Exist

We're not really sure where this theory came from, but it's pretty wild, considering, you know, the moon is right there if you just look up.

Some people, like Dave Marsh—who is also a flat-Earther—say the moon is a projection.

"The moon is a projection, put there for a reason, which we could study for a thousand more years and never understand," Marsh told The Guardian.

To arrive at this conclusion, Marsh followed the path of the moon in the sky in order to compare his findings to official records. Because his findings were not the same, Marsh determined the moon was a scam.

Oh, and the moon is also a hoax because it was created to distract the general masses from the existence of Nibiru, a rogue planet that will cause the apocalypse. Do with this information what you will.
