I think you are confusing your quantum mechanics terminology . You are referring to the double slit experiment and the superposition of any given thing . It states that ' reality ' can change depending on the observer , but there is nothing to indicate that this is the result of one single event taking place that split the universe into multiple timelines , or our ability to have any influence on reality . With this kind of reasoning you have crossed over from recordable quantum mechanics into pseudo science . Furthermore , the ME isn ' t a new thing . It could have been going on for decades , its just that with the nature of the internet and the ability for informationideasconcepts to suddenly go viral , its now suddenly become a thang . That , and perhaps CERN screwing around with the very fabric of space and time last year
