What is it?
The “Mandela Effect” is what happens when someone has a clear memory of something that never happened in this reality. Large groups of us – total strangers – remember the exact same events with almost identical details. However, our memories are different from what’s in history books, newspaper archives, and so on.
This isn’t a conspiracy theory, and we’re not talking about “false memories". Some of us speculate that parallel realities exist, and – until now – we’ve been sliding between them without realizing it.
The Mandela Effect is named after the famous Nelson Mandela (who some remember as dying in prison in 2013, but who others remember dying a free man years later). The effect is when a large group of people remember something being a certain way, but when people go back and look at it, it has changed, or is gone in this universe with no reasoning other than "it's always been like that"
Two popular theories on the Mandela effect are:
Time Travel ~ Some believe that time travelers have come back to the past and changed one little thing that ended up changing many other things kinda like the butterfly effect. Think about it. The future has already happened, so even if time travel is say 1000 years in the future, it has already been done, which means time travelers are going back to the past, which is our present, and changing little things.
Parallel Universe ~ Others believe that sometime in the last decade or two the world went through a black hole, or that our "original world" ended, and now we are in this Parallel Universe. It's believed something changed in the process of switching, or going through the black hole. (It's been speculated that in the years 2000 or 2012 this happened, because many thought the world was gong to end)
Some of the most popular mandela effects ~
Berenstain Bears or Berenstein Bears – Which do you recall? (Still one of the most popular topics at this website.)
Challenger shuttle explosion date? 1984, 1985, or 1986? Winter or another time of year? (Per Wikipedia, it was 28 Jan 1986.) Also, alternate memories about the Columbia.
Colors – Chartreuse and more – Many people recall chartreuse as a pink or reddish color. It’s actually yellow-green.
Curious George – Tail or no tail? (He’s never had a tail.) This is part of my article about dual memories.
Ghost Hunters TV show – Some remember the earliest show name as TAPS, not Ghost Hunters. (Yes, we know the real-life team is called TAPS, and some of their gear has always said that.)
Henry VIII portrait with a turkey leg in his hand – Many people clearly recall seeing it in history books, but there’s no record of it, now.
Jif or Jiffy Peanut Butter – Jif peanut butter was never called “Jiffy,” in this timestream. (Not confused with Skippy brand, either.)
Lindbergh baby – Never found? In this timestream, the 20-month old baby was found 12 May 1932.
Mother Teresa – A saint before 2016? Several recall her canonization in the 1990s. They also recall her name spelled “Theresa.”
Nelson Mandela’s death in prison, long before his actual death (in this timestream) on 5 December 2013. (This was the alternate memory that launched MandelaEffect.com)
Red/blue – Pepsi logo changes, Chevron logo changes, and other color swaps… are they markers, cues, or signs to watch for?
September 22nd or 23rd? – Some people recall events shifting from one of these dates to another. (The reaction to this article – on- and off-site – has been disproportionate to its apparent minor importance.)
Sky – Changes in the sun, moon, stars, planets and their moons, constellation configurations and placement, and the color of the sky in general. ...EDIT: Note, Yes! Not only have I been aware of this, but family members as well!
Tiananmen Square – Memories of a young man being run over by a tank. (Might be Mandela Effect issue or simple media manipulation.) ...EDIT: Note, I remember him being moved out of the way by two men in uniform. What do you remember?
