Disproof of Many Worlds of Quantum Mechanics

[questfortruth]

It is demonstrated that the many world interpretation of Quantum Mechanics is a useless, unpractical idea. The many world interpretation was aimed to make the path from one universe to another a deterministic process. But that goal was not achieved: modern experiments have proven that quantum superposition is a real thing in our universe. In particular, these are the experiments with the quantum entanglement of particles.

\section{Original Interpretation}

If there is only one universe, it is determined by the Copenhagen interpretation: the wave function follows Schrödinger's equation with the wave function collapsing either to state A and state B of the system.

\section{Adding many-worlds philosophy}

If the possible outcomes are A and B, then according to the Many Worlds Interpretation, outcome A happens inside universe A, and outcome B happens inside universe B. Now comes my logic:

In order to find out what laws of nature hold inside of universe A, one
again has to use the Copenhagen interpretation: the wave function follows
Schrödinger's equation before it collapses. Namely, no law of nature, no
observation inside our universe can make us sure that there are many worlds
out there.

If we have the Copenhagen interpretation, the many-worlds add nothing new.
We must use the Copenhagen interpretation to make practical predictions inside
the universe A, even being followers of the many-worlds interpretation.

Your argument fails the test of scrutiny and is an outdated and primitive concept.

Many-worlds is a reality as dictated not only by the experiments of Quantum Science but logic as well.

Even for the sake of argument if we assume that there is only one universe that still does not explain how a single photon can exist in two places at once.

The photon passes through both slits in a different Quantum universe and the interference is between the universes.

Your failed attempt to convince readers that the dreams of Quantum mechanics and its holy grail falls flat on its face when faced with the tests of reality.
