Isolated Particle Multiverse Theory

In my previous article about the hypothetical multiverse, I introduced a new concept that I called the Isolated Particle Multiverse Theory. I briefly stated in general what I assumed a real multiverse would actually be like. In this article, I will flesh it out a little more.

So, in this proposed framework, the multiverse exists, but it wouldn't matter because each new universe would only be one choice the particle could have made. It would merely be a particle isolated from our universe in a way as to be itself a new, tiny universe, unable to be traversed by anyone. In fact, according to physics, the particle would be disintegrated into a tiny quarck and gluon plasma soup if the new universe is just a true void. If it is just empty, regular spacetime, the particle would survive.

This theory might be a realistic explanation for the bizarre trait quantum particles possess known as superposition, where the particle exists as many possibilities until it knows it is being observed, and at that point, is forced into a single point.

So, this theory is a proposed explanation for superposition that uses a type of multiverse to do it, but that multiverse is in practicality insignificant and pointless, but still a novelty to think that any kind of multiverse actually exists.

So what about us? Do the choices each person could have made spawn new universes? And would that universe merely be a variant of the person who could have made that certain choice?

Of course, there is no scientific answer to this answer apart from superposition, which makes multiverses heavily theorized, but according to my theory, the answer to that last question would be yes. Each potential choice is isolated in a separate, insignificant universe. Which, like I said, has no bearing on true reality except as a thought experiment.
