There have been videos on youtube recently that suggests C.E.R.N. has opened a portal in which a parallel reality has emerged and altered the past history on various things. The theory is called the Mandela Effect...Makes a good Twilight Zone episode. This posting is one example of the things they claim. And I also discredit that claim in this posting as well.
Past deceivers had brought up things that were truthful, And then would then contradict the public that a fallacy they had fabricated is the truth instead...Sometimes they use to try to back it up with a photo-shopped image of something. This older method of smoke-n-mirrors can easily be debunked with archives, old photos and old newspaper clippings.
The deception of this one is more clever. They begin with agreeing with the public on popular mispreceptions about past and historical things (and there are more of them than you would think). Then they will produce actual truthful evidence of the correct way something is...If a photo is the proof, it is not altered, but there is a deception to it.
They will not say, "You were mistaken. I have proof of that. See this old photo?"
They will instead say, "The way we all knew history is no longer that way. A portal from CERN has altered history. Look at this old photo. We never knew things this way. And this old photo now shows it the way the past is now. History has supernaturally changed, and this photo now shows it".
In actuality, that photo had always been correct from the beginning. They are using popular mispreceptions most people have of history as a tool of deception. With this more cunning method of smoke-n-mirrors, someone who falls for the deception could be looking at the old newspaper clippings their Grand Dad had from 1963, and swear up-n-down that the parallel reality from the C.E.R.N. portal had supernaturally altered the photos to include Governor Connelly and his wife riding in the limo.
I other words, instead of lying, they are turning the truth into a lie...or present the truth as an alteration of history.
I posted a 3:45 Youtube slideshow video debunking the theory, and it has a catchy R&B song about magic; https://www.youtube.com/watch?v=PjXGt7t6w_8 Between footages 0:20 and 0:30, someone who was only glancing at the video might think they were tripping out.
