On June 29, 2026, CERN turned off the world’s most powerful particle collider. This planned 4-year shutdown, known as Long Shutdown 3, is part of a major maintenance and upgrade phase that will turn the Large Hadron Collider into a more advanced and better performing machine. Though, to fringe pockets of the internet, that’s just the official story.

Social media is buzzing with posts like “The machine is being turned off so the real light can fully turn on — the loops are breaking, the door is wide open.” Some claim the shutdown has caused reality to jump timelines, open or close portals to alternate dimensions, or accelerate the passage of time.

In fact, this is just the latest in a long string of conspiracy theories that have plagued the particle collider throughout its history, thanks in part to the advanced, difficult-to-understand science it’s designed to do. To some people, uncertainty can look like a cover-up.

What CERN and the LHC Actually Do

CERN is a massive atomic physics laboratory just outside Geneva, Switzerland that’s home to a number of particle accelerators, which are machines that accelerate tiny particles, like electrons, protons, and sometimes even whole atoms, to very high energies in order to study what happens when they collide.

Particle accelerators have advanced our understanding of the universe, led to technological breakthroughs, and even enabled the creation of lifesaving medical treatments like radiation therapy.

At 27 kilometers long, the Large Hadron Collider, or LHC, is the largest, most powerful particle accelerator not only at CERN, but in the entire world. It has enabled a huge number of discoveries, perhaps the most famous of which is the Higgs-Boson — the so-called “god particle” that gives mass to all other particles.

What makes CERN such a tempting target for new-age philosophers and conspiracy theorists is that it is actually used to answer questions about alternate dimensions and the unknown. As a result, over the last two decades, a complex mythology has grown around it.

CERN Conspiracies: A Chronological History

Wave 1: The Black Hole Panic

Conspiracies about the LHC date back to its very first moments. The origin of the first conspiracy was already covered by Skeptoid nearly 20 years ago: in 2008, two people — a retired nuclear safety officer and a journalist — filed a lawsuit alleging that the LHC could create black holes and seeking to stop the collider’s operation until that risk could be adequately studied.

It may sound outlandish, but there was substance behind the allegation: particle collisions can potentially concentrate enough matter to form microscopic black holes. But in a safety report published in response to the lawsuit, CERN noted that even if these tiny black holes did form, they would decay too quickly to grow to a dangerous size.

Still, the media coverage of the black hole risk was massive. More than a billion people tuned in to watch the LHC switch on in September 2008 in an event that MSNBC reporter Alan Boyle called “bigger than Britney,” and LHC physicist John Ellis was quoted as saying “Of the billions who tuned in for the switch-on, I suspect that many were only interested in seeing whether or not we would be blown to smithereens.” Physicists received death threats connected with the LHC turning on, and fears of global annihilation even led one person to die by suicide. On a lighter note, a website with the URL “hasthelargehadroncolliderdestroyedtheworldyet.com” made the rounds as a tongue-in-cheek resource for the LHC panic.

The LHC turned on, did not end the world, and has since led to numerous scientific breakthroughs. But that hasn’t stopped the conspiracy theories from growing.

Wave 2: The Higgs Boson discovery

On July 4th 2012, researchers at the LHC discovered the long-sought-after Higgs Boson, the fundamental force-carrying particle of the Higgs field, which is what grants other particles their mass. This was another widely publicized discovery that broke the perimeter of science news to land in the public consciousness — and formed its own conspiracy theory as a result.

According to proponents of this theory, while physicists were researching the Higgs boson, something went terribly wrong. The experiments caused a rift in the space-time continuum, which destroyed our universe and moved us into a parallel timeline.

Many believe this is the cause of the so-called Mandela effect: the phenomenon where large numbers of people all seem to misremember the same things about history, like that Nelson Mandela died in prison in the 1980s (he didn’t) or that there was a movie called “Shazaam” that featured Sinbad as a genie (there wasn’t). The theory says that these things used to be true, but we moved into a different timeline and these altered details are evidence of that shift.

Wave 3: The Shiva Statue and a Human Sacrifice Hoax

In 2004, CERN unveiled a two-meter bronze statue of Shiva, the Hindu deity also known as “the cosmic dancer” or, alternatively, “the destroyer” — a metaphor for the “dance” of subatomic matter and the patterns of the cosmos. The statue was a gift from India to honor CERN’s long relationship with the country. But a statue of a god called “The Destroyer” at a facility already suspected of bringing an end to the universe was bound to cause rumors.

In 2015, the LHC turned back on after a two-year hiatus. In 2016, a video circulated online depicting several people in black cloaks gathering by the Shiva statue in what appears to be an occult ceremony. A woman lies down in the middle of the gathering and one cloaked figure appears to stab her repeatedly. The video is filmed from the perspective of a viewer secretly watching from a window above, and as the ceremony reaches its peak, the viewer lets out a string of expletives and runs away.

The video turned out to be a prank filmed without CERN’s official involvement, likely by visiting scientists poking fun at the conspiracy theories swirling around the facility. A CERN spokeswoman said at the time, “CERN welcomes every year thousands of scientific users from all over the world and sometimes some of them let their humor go too far. This is what happened on this occasion.”

Few still cite the ritual video as evidence of a conspiracy at CERN, but the Shiva statue continues to be used as evidence of occult activity there.

Wave 4: Portals to Alternate Dimensions

In December 2018, the LHC turned off for Long Shutdown 2, and collisions didn’t happen again until July 5th, 2022. The conspiracy theorists were ready for this new run of the collider — but their theories had changed shape. Black holes and ritual sacrifice gave way to a new frame: the portal. Part of this was cultural timing: Stranger Things and Doctor Strange had both put fictional versions of interdimensional gateways in front of huge audiences that year, and viewers made the connection to CERN almost immediately.

One tweet read, “Be ready for July 5th everyone. That's all I'm saying. Protect your energy. Be alert. Don't do things that lower your vibration, your energy, or your focus. CERN will be opening a portal on July 5th. They began getting it ready when the planets aligned on June 24th.”

This is the moment when a new character entered the story: Dr. Astrid Stuckelberger, a figure repeatedly called a “Swiss scientist” by proponents of her claims — though her PhD is in public health, not physics. Stuckelberger rose to prominence as a supposed WHO whistleblower during the COVID-19 pandemic, when she claimed the COVID vaccine had caused 18,000 deaths. The truth was that these were deaths reported after the vaccine, not necessarily because of the vaccine.

In 2022, Stuckelberger took on the mantle of “CERN whistleblower.” She started appearing on podcasts making claims about otherworldly phenomena at the facility, and described attending a dinner in 2016 where she was seated next to two CERN physicists. She started the conversation by asking them how many dimensions of reality actually exist, and they told her 17. These physicists went on to say there was a portal beneath CERN’s facility that a “being” had reportedly come through — not once, but several times. On one occasion, she says, it left a scarf behind. Stuckelberger has told this story repeatedly across multiple podcast appearances, sometimes adding details about an underground tunnel from CERN to the UN, a CIA base under Lake Geneva, a time machine at the Vatican, and claims about EMFs and dowsing.

Clips from Stuckelberger’s interviews calling her a “CERN whistleblower” have proliferated throughout social media. A secondhand anecdote from a conversation that happened years before she started sharing it is now the fuel for a new round of conspiracy theories.

Wave 5: 2026 and Long Shutdown 3

On June 29 2026, CERN switched off the LHC to begin Long Shutdown 3, a planned four-year maintenance period that will prepare the collider for its next, more powerful phase. Almost immediately, the same mythology that’s followed the collider since 2008 resurfaced.

The claims take a few different shapes, depending on which corner of the internet you’re in. Some frame the shutdown as a kind of release, with posts describing “the loops breaking” and “the door” finally opening now that the machine has stopped running. Others tie the shutdown to spikes in the Schumann Resonance, a real, measurable set of electromagnetic frequencies in the Earth’s atmosphere, and claim these spikes are making people feel physical effects like joint pain, dizziness, or a racing sense of time. There are other strands, too: people who claim CERN causes earthquakes, for example, or that time travelers are sabotaging experiments at CERN to prevent a world-altering discovery.

At this point, it seems unlikely that the conspiracy theories will ever stop — they’ll just take on new forms and formats for newer audiences.

Why CERN is so Ripe for Conspiracy Theories

CERN is an unusually good target for conspiracy theories for a few reasons. The science performed there is some of the most advanced subject matter there is — even physicists sometimes struggle to explain their work to non-scientists. For a certain subset of the population, that opaqueness can feel sinister, like “they” aren’t fully explaining what goes on there in order to keep us in the dark.

There’s also the fact that theoretical physics really does talk about some of these out-there concepts: extra dimensions, time dilation, wormholes, black holes. Scientists really did think collisions in the LHC could form black holes. Physicists talk about their work with words like “portal” to refer to microscopic, instantaneous, and entirely theoretical “openings” to alternate dimensions, which are easily twisted in headlines to suggest human-sized portals a la Stargate — and when a fringe PhD says a being walked through one at CERN and left a scarf behind, it’s easy for people to believe.

None of this requires anyone involved to be foolish. It requires a difficult subject, a few ambiguous details, and a story that’s emotionally satisfying in the way “the machine is being upgraded on schedule” never will be. It’s the same set of ingredients combined in a new way every time CERN makes the news, for almost two decades running.

So the LHC is dark for now, and by the time it switches back on in 2030, the mythology will have had four more years to grow. Maybe it'll be a new whistleblower. Maybe a new platform, or a new movie that gets people thinking about portals again. But if the last 18 years are any guide, one thing won't change: somewhere between what CERN actually says and what people want to believe, this story will find room to grow all over again.
