Why throws pearls at swine.
Except for one major thing. Reality in something has only one thing. There are not two or more realities. That kind of thinking is theory.
I can prove you are wrong.
What is the reality of 1 billionth person in India today? Obviously you can't possibly know and thus you and he/she have different realities. Fact is that for you to know all the realities in real-time (because history can always be a lie if you did not experience it live) would require the speed-of-light to be infinite, which would thus collapse the past into the future into an infinitesimal point in spacetime and thus nothing could exist. Friction insures multiple realities, and there is no other possible way anything could exist.
You don't realize how ignorant you are, which is typical Dunning-Kruger disrespect.
