Simon Parkes, who until April was a Labour town councillor for Whitby in North Yorkshire, claimed "psychopathic" members of a group of world leaders, known as the Illuminati by conspiracy theorists, were hellbent on using the huge atom colliding machine to open a vortex that would allow them complete control over all of us.
The LHC, run by the European Organisation for Nuclear Research (CERN) at Geneva on the French-Swiss border, is the world’s largest and most powerful machine and used to collide particles at close to the speed of light in a bid to discover more about physics and the possibility of parallel universes.
The curious machine developed across a 16-mile ring of superconducting magnets has had critics before amid claims it could inadvertently create a black hole that may swallow up the world, but Mr Parkes' story is one of the strangest to date.
Mr Parkes, who has previously been a borough councillor in London and lectured at the Natural History Museum, made the extraordinary claims before hundreds of people during a paranoia-inducing speech at a UFO convention in a country manor house.
Conspiracy theorists claim the Illuminati is a worldwide secret organisation which really runs the world above the global leaders we see in office.
He claimed to have foiled a sinister plot by the "elite group" just weeks ago in August to use the LHC to open an evil portal that would allow them to become more powerful.
Mr Parkes, who has earlier made national headlines after saying his mother was alien, and he lost his virginity to one, was the key speaker of the event organised by the UFO Academy at High Elms Manor in Watford, Hertfordshire.
So many people turned out to see him there were people seated in a corridor outside the main hall and others watching it on a live stream in another room.
He even said the LHC was developed using alien technology from another planet by evil Illuminate scientists to "interfere with time, open portals to other dimensions and severe the link between good humans and the spiritual plane and divine consciousness."
He claimed an attempt was made to severe "the link" on August 15.
He said: "It became very obvious the LHC was going to be used for a pivotal roll on August 15 this year."
This was a month after the announcement that the LHC had discovered a new particle known as a pentaquark.
Mr Parkes said: "I have not said the LHC can break the divine link between all good humans on this plane and divine consciousness, but that was their plan."
But Mr Parkes claimed to have sources who made him aware of what was about to unfold, so he set about arranging a global "mind warp" to defeat the plan.
He said: "We couldn't just do nothing. There is much you could do without sticking your head above the parapet.
I have not said the LHC can break the divine link between all good humans on this plane and divine consciousness, but that was their plan.
The LHC came back on, but they thwarted it again, he claimed.
He said: "All over the globe good people started to meditate for five to six minutes, after the meditation it failed again, but we did take some damage. One person lost hearing in an ear for three weeks and others had ringing in ears because there was an attack by those psychically protecting it."
He claims the mass meditation caused a thunderstorm over Switzerland, meaning the LHC was forced onto a back-up power system which only gave a thirds of its full capacity.
He said: "Gaia came to our rescue and a thunderstorm took out the power."
According to New Age philosophies Gaia is an all powerful force govering the universe.
He said: "With just a third of the power it created a 0.8mm hole between the third and fourth frequency, but that was not enough to bring anything through."
There is, of course, no evidence that the LCH was used in any such attempt or that Mr Parkes and his group stopped it in its tracks.
However, his conspiracist claims did disturb some audience members.
One woman, aged in her 50s, who would not be named, told Express.co.uk: "I was expecting to come and learn about UFO sightings, but all the speakers were pretty out there even by UFO standards. I found Simon's talk quite disturbing and it makes you wonder where on Earth this is all coming from?"
But a man, in his 20s, said he trusted the advice.
He said: "Simon is spot on with all this. If he says it happened, it happened."
Express.co.uk has contacted CERN, which runs the LCH, to see if it wishes to respond to the extraordinary allegations, and awaits a response.
Mr Parkes also said the failure of the LCH plan meant the cruel Illuminati leaders needed a new plot as there were just 200 of them left on Earth, after some of them had fled the planet.
He said: "For 25 years it has been known the psychopaths want to kill half to a third of the population.
"But now they may not need to kill so many because of what they are planning next."
