@Aéius Cercle:
"Provide falsifiable experimental-protocol if possible."
Sure. It's called the scientific method:
1. Observe a phenomenon that's happening in reality.
2. Set up a theory that could explain the phenomenon.
3. Formulate the conditions that can prove the theory wrong.
4. Apply the conditions and observe whether the theory and reality match.
Regarding the Mandela effect:
Observation 1: The majority of humans on this planet is obviously unable to think outside the box of a given religion or ideology.
Observation 2: Science is degrading into a tool of the authoritarian ruling class. The search for truth is being pushed in the background. People lose the ability to ask important questions. People lose the ability to admit that they are wrong. People lose the ability to change their minds.
Observation 3: The Mandela effect makes people question reality. They start to ask important questions again. They are forced to admit that they could be wrong. They are forced to change their minds.
Theory: Consciousness of humans on this planet is being tampered with. It's "compressed" into a state of inability to interact with physical reality in a meaningful way. The purpose of the compression is to ensure that humans lose the ability to do real science, thus losing the ability to identify – and get rid of – the control mechanisms of the "prison planet".
The so-called "Mandela effect" is an attempt to counteract this compression of consciousness. People are confronted with phenomena that don't fit into the narrative of the predominant authoritarian ideology.
Conditions that can prove the theory wrong:
1. If humans were allowed to interact with reality in a free manner, asking difficult questions should neither lead to ignorance nor oppression of the people who ask the questions. True science would take the matter seriously. True scientists would conduct experiments of various nature in order to investigate the Mandela effect. In other words: To expand consciousness into the unknown.
Observation: This doesn't happen at all. Phenomena like the Mandela effect are mostly being ignored by mainstream science, and where there is no ignorance, the phenomenon is explained away without adhering to the scientific method.
2. If the theory is wrong, investigating the Mandela effect should yield no useful insights about the nature of reality.
Observation: We are not at this point yet, because most people that are fascinated by the Mandela effect don't apply the scientific method. They provide explanations – like the CERN theory – without providing evidence. Videos going viral are not statistical evidence, because they provide subjective conclusions, not objective observations. In other words: The requirements for statistical data haven't been met.
3. Attempts to replicate the phenomenon fail.
Observation: We are not at this point yet, because attempts to replicate the phenomenon have not been made. At least not in public.
