The so-called "Mandela Effect" or the "Quantum Effect" is an unexplained phenomenon. There are many hypothesis as to what may be causing this effect where things change contrary to our collective memories. Below is a secular video from Youtube user Top5s entitled

"The Mandela Effect | Examples & Possible Explanation | Documentary"If thought out logically there are some explanations that we can dismiss. One such illogical explanation is that someone traveled back in time and made the changes we see today. If this were true then we would all have the same memories of these events and there would be no controversy. For instance we would all remember "magic mirror on the wall", instead of "mirror, mirror on the wall". Besides, how would someone be able to get the script writers, actors, and directors to change the words? But, the problem gets worse when you consider the dozens of songs and movie changes spanning different decades.Another hypothesis is that an alternate reality has somehow impinged on ours. This parallel universe miraculously has the same people we do (all with the same names and geneology), schools, music, movies, newspapers, corporations, art, science, countries, oceans, continents, animals, sun, moon, stars, laws of physics, and a million other impossible coincidences. Also there is zero evidence of parallel universes, except in hundreds of Hollywood movies, TV series, and other media propaganda.There are powerful clues as to who some of the players are behind this phenomenon. Below is a photo of a CERN physicist holding a tell tale sign before the "Mandela Effect" was known. This picture is a little small here, but there is an orange sign that reads, "Mandela" on it.In the secular world the changes are meaningless, and just a curiosity. In the Christian world the changes are enormous, and very serious indeed. The "Mandela Effect, or the Quantum Effect", or what ever you want to call it seems now to be setting it's sights on the Bible, Christian literature, art and doctrines.I don't know what is causing this "Mandela or Quantum Effect" (although I suspect I do) but I DO know that if this were simply a random event then the secular world should be experiencing changes of the same magnitude as Christianity, but they are not.This website MandelaBibleChanges.com was built to document the ongoing major changes and help preserve the facts as we knew them. On this site we will be documenting many examples of undeniable changes that were unmistakably engineered to undermine God's character, the scriptures, doctrine, and the Truth!
