A brief look at quantum physics and multiple world's or alternate realities 

In 1954, a young Princeton University doctoral candidate named Hugh Everett III came up with a radical idea: That there exist parallel universes, exactly like our ­universe. These universes are all related to ours; indeed, they branch off from ours, and our universe is branched off of others. Within these parallel universes, our wars have had different outcomes than the ones we know. Species that are extinct in our universe have evolved and adapted in others. In other universes, we humans may have become extinct.

This thought boggles the mind and yet, it is still comprehensible. Notions of parallel universes or dimensions that resemble our own have appeared in works of science fiction and have been used as explanations for metaphysics.

Why does quantum matter behave erratically? The quantum level is the smallest one science has detected so far. The study of quantum physics began in 1900, when the physicist Max Planck first introduced the concept to the scientific world. Planck's study of radiation yielded some unusual findings that contradicted classical physical laws. These findings suggested that there are other laws at work in the universe, operating on a deeper level than the one we know.

all quantum particles don't exist in one state or the other, but in all of its possible states at once. The sum total of possible states of a quantum object is called its wave function. The state of an object existing in all of its possible states at once is called its superposition.

According to Stephen Hawking, renowned theoretical physicist and cosmologist mysterious, destructive, dark parts of the universe could answer one of the most puzzling paradoxes of physics - the existence of parallel universes. Stephen Hawking has argued in favor of the parallel universe theory for many years.

The Mandela effect

The Mandela Effect refers to a situation in which a large mass of people believes that an event occurred when it did not.

Origins of the Mandela Effect

The term "Mandela Effect" began when it was first coined in 2009 by Fiona Broome when she published a website detailing her observance of the phenomenon. Broome was at a conference talking with other people about how she remembered the tragedy of former South African president Nelson Mandela's death in a South African prison in the 1980s.

However, Nelson Mandela did not die in the 1980s in a prison—he passed away in 2013. As Broome began to talk to other people about her memories, she learned that she was not alone. Others remembered seeing news coverage of his death as well as a speech by his widow.

Broome was shocked that such a large mass of people could remember the same identical event in such detail when it never happened.

Examples of the Mandela Effect

1) Nelson Mandela died in prison in the 1980s

Mandela died in 2013 - look it up!

2) Darth Vader's line "Luke, I am your father

He actually JUST said "I am your father

3) Snow white - "Mirror mirror on the wall"

She actually said "magic mirror on tte wall"

4) Mr moneybags the monopoly mascot had a monocle

He does not in fact have a monocle

5) The Berenstein bears never were

It's actually the Berenstain bears

6) Henry VIII eating a turkey leg

Most people remember this image however no such picture exists

7) Febreeze the air freshener

Is actually spelt Febreze

These are just a few examples of the Mandela Effect

One theory about the basis for the Mandela effect originates from quantum physics and relates to the idea that rather than one timeline of events, it is possible that alternate realities or universes are taking place and mixing with our timeline. In theory, this would result in groups of people having the same memories because the timeline has been altered as we shift between these different realities.

Many conspiracists believe it is the work of the LHC (large hadron collider) creating or resulting in overlapping realities from the experiments.

Scientists attempt to rationalise this concept citing different types of memory.

False memories

When memories are recalled, rather than remembered perfectly, they are influenced to the point that they can eventually become incorrect. In this way, memory is unreliable and not infallible.

Memory related concepts

Confabulation: Confabulation involves your brain filling in gaps that are missing in your memories to make more sense of them. This isn't lying, but rather remembering details that never happened. Confabulation tends to increase with age.

Post-event information: Information that you learn after an event can change your memory of an event. This includes event subtle information and helps to explain why eyewitness testimony can be unreliable.

Priming: Priming describes the factors leading up to an event that affects our perception of it. Also called suggestibility and presupposition, priming is the difference between asking how short a person is, versus how tall a person is.

In essence, memories are vulnerable bits of information stored in the brain that can be changed over time. While we assume that our memories are accurate, this is not necessarily the case.

In this author's opinion I'm gonna go with the crazies as I definitely remember a lot of the examples being the former rather than the latter... Unless my brain is playing tricks, but how could so many people remember the same identical events as false memories?
