Okay, let’s talk about the Universe. The only reason that people have ever theorized as to whether or not a multiverse exists is to explain dreams or fantasies. There is no, and I mean no, genuine scientific research that confirms or implies a multiverse that is not more consistent with some other finding.
So why do people believe in it? Delusion, fantasy, wishing they had a better life than they do now. To sell books on theoretical physics. Science fiction television writers, and also movies, I guess.
Why is it important that people stop believing it? It is being used as a manipulation tool. People are being told to slave away in this life because on the next one they can be a space soldier in Star Trek, or go to Heaven, or that they are just one version of themselves and every other version of themselves is better or worse.
Let’s think about the Universe. Presume that the Universe originated with two points at imbalance, or one become imbalanced. Every single motion those points take and make are determined by the arrangement, charge, spin rate, spacing, and so many other factors. They only move in that direction once and that was always and will always be the direction they were going to move.
This isn’t a probability trial where you get to retest the results and measure each one as a classed alternative series of events. That isn’t the Multiverse, that’s just measuring multiple instances of similar actions.
If you go back in time, you were already there, and that’s why you can’t change anything and another reason as to why there is no Multiverse.
Why is it important to reject the idea of the Multiverse and a mutable timeline? Idiots are trying to change the timeline and they’re using the idea of the Multiverse as part of their justification. This wouldn’t work and is just causing harm. Basically, it’s to explain to all of the theoretical physicists and actual idiots, and the overlap.
Edit: Apparently someone reported this post as offensive? I edited the title slightly but if it gets flagged again I ask that moderation consider the value of the statement.
