“The Many-Worlds Interpretation” and Possible Paths

The circulation of life, all is intertwined. Sometimes I believe that everything that I have lived is part of a meaning. Sometimes I doubt, because the cause and effect of the “event” depend on the observer, and I know that feelings are tiltable and bendable. I can also model feelings as liquid, so it conforms to the shape of its container, which depends on our personal perspectives and paradigms.
What makes a decision a good choice or bad choice? The result? What if it is not an immediate result? “I took the one less traveled by, And that has made all the difference,” says Robert Frost in his poem “The Road Not Taken.” What about the other ways? I mean all possible ways. Is it possible to follow all paths at the same time?  The answer is “yes,” according to one interpretation of quantum mechanics.
Quantum mechanics explains the behavior of matter and light on the atomic and subatomic levels. To understand (I mean to try to understand) quantum mechanics in daily life, there are two major interpretations. Let me summarize them briefly:
The Copenhagen Interpretation:  Niels Bohr suggested the Copenhagen Interpretation, which asseverates that “a particle is whatever it is measured to be (for example, a wave or a particle), but that it cannot be assumed to have specific properties, or even to exist until it is measured. In short, Bohr was saying that objective reality does not exist. This translates into a principle called superposition that claims that while we do not know what the state of any object is, it is actually in all possible states simultaneously, as long as we don’t look to check[1].” Schrodinger’s Cat is the typical analogy for the explanation of the Copenhagen Interpretation. We have a living cat and we place it in a thick lead box. Then we throw a bottle of cyanide in and close the box. We do not know if the cat is alive or if the cyanide capsule is broken and the cat died. So the cat is both dead and alive according to the superposition law. Only when we open the box and the superposition of the cat’s state is lost do we know whether the cat is alive or dead.
The Many-Worlds Interpretation: This interpretation belongs to H. Everett [2],  who stated that there are many worlds which exist in parallel, that is, in the same space and at the same time as we do. This assumption is based on quantum mechanics, which is very different from our daily life’s classical mechanics. For example, in classical mechanics, you can simultaneously measure the position and the momentum of a moving car. But on small scales, that is, in a quantum world, “The position and momentum of a particle cannot be simultaneously measured with arbitrarily high precision [3].”  This leads an object to have a potential to be in any state. “…. the universe of that object transmutes into a series of parallel universes equal to the number of possible states in which that the object can exist, with each universe containing a unique single possible state of that object. Furthermore, there is a mechanism for interaction between these universes that somehow permits all states to be accessible in some way and for all possible states to be affected in some manner [1].”
So, according to “The Many-Worlds Interpretation,” following all possible ways is possible. You create a universe in every choice you make, and in each of these universes, you make other choices so you create an infinite number of universes as real. This means that while you are a  good person in one world, in another one you can be a sinner. In this way, you are all the colors of the light spectrum. You live everything, every possible feeling, every possible scenario. 
In the words of Aldous Huxley: “Maybe this world is another planet’s hell.” We cannot know how many worlds we have and where are we now. In my opinion, the main idea of life is to live, to feel in the superposition of all worlds; I mean to live all of them at the same time and to feel the summation of all at least as a wise man. I call this “zero” state, no happiness, no pain, just existential peace.  I’d like to finish with a beautiful poem by Rumi for those who doubt their paths:
God renders the bad goodDon’t assume God would render it  any other wayThe enlightened one watches it happenLet’s see what the Companion makesWhatever God makes, It renders it beautiful
