Quantum Machanics, Quantum cumputing, parralel universes and the mandela effect!

[TrianonDave]

Anyone got any views, knowledge of this theory? come on Bongo, must be right down your street? apparently, things are switching before our eyes and explained by using the phrase Deja vu.

Things like name changes and memory switching or misunderstanding, educational theories which keep changing?

question, where did Nelson Mandela die? |Snow white, was it magic mirror on the wall or mirror, mirror?
Jif or Jiffy. snickers or marathon?
Henry viii painted with a turkey leg in his hand but you cannot see it now?
Sky logo red or blue?
Tiananman Square, ma standing in front of the advancing tank, was he killed or did he survive?
9/11 seven planes hijacked or was it 4 or even just 2??

The theory is that there are super computers that we are actually part of in a real Matrix or ones that can change reality history and the past as well as being a portal to alternative dimensions! I do not pretend to understand it but find it fascinating...latest block buster on Sky is 'West-world' is this a hint or trying to explain the matrix?
