The 4 Interpretations of Quantum Mechanics

As many people know there are quite a few interpretations of quantum mechanics and what role it plays in our universe. Two of the most influential of these are the Copenhagen interpretation and the Many worlds theory

Quantum Mechanics

Quantum mechanics is a theory to explain matter at an atomic scale. Many scientists have worked on a theory. The two most prominent are Erwin Rudolf Josef Alexander Schrödinger and Niels Bohr.

One of the main reasons for so many theories is that: how quantum mechanics affects the real world is exceedingly difficult to visualize and explain even with the many experimental results obtained. This stems from quantum mechanics being a sum (or interplay) of different terms. Each term describes a physical state of the quantum mechanics system.

What brings the complicated part of quantum mechanics is that the theory must account for the interactions between them, but all of these terms are unable to exist simultaneously and each time experiments are done with these terms only one of them can be seen in the measurement which prevents any term to be given importance over any other terms. This paradox is what created all these interpretations.

The Copenhagen Interpretation

This is quite an interesting interpretation of quantum mechanics as not only does it tie in physics, but Maths also plays an influential role in it. This is because the state of the particle is dependent on probability. A particle exists in all terms at once but once we observe it is forced to enter one state of matter is what the Copenhagen interpretation states. Coherent superposition is when particles exist in all terms but can be only viewed in one. This explains the unorthodox behavior of subatomic particles. Since this theory makes the most sense to physicists however, the Many worlds theory is remarkably close behind as second best.

Many-Worlds Theory

The Many worlds theory is what created the concept of infinite universes as there are infinite possibilities. The realities exist in the same space and time. It states that the existence of these parallel realities removes the randomness and action from quantum mechanics. This can explain why the measurements obtained experimentally exist in a single term only. This created the concept of Quantum decoherence which explains how the randomness of this subject affects daily life.
