Everett interpretation

The quantum multiverse: "Quantum mechanics suggests that every possibility embodied in its probability waves is realized in a vast number of parallel universes."

• This is similair to the Many-world's interpretation of quantum mechanics, which I have described above.

• Every time a diversion in events occurs, there is a new universe created.

In 1957, Hugh Everett proposed the Many-worlds interpretation of quantum mechanics. Instead of the measurement of a quantum system reducing the system from a number of potential outcomes to one definite outcome, the entire Universe will split into a number of parallel realities equal to the number of potential outcomes. 

The Level III multiverse brings in quantum mechanics. This is the MWI or Many-Worlds interpretation of quantum mechanics. This was a proposal made by Hugh Everett III. It must first be understood, that, in quantum mechanics, certain observations, exist in a range of different potential or possible observations. This is known as the wave function of a quantum system. Each of these observations in quantum mechanics has a corresponding probability (of it being observed to have actually occurred). We say that the wave function is in a superposition (undetermined state) of several different potential outcomes (known as eigenstates in quantum mechanics). When the wave function, upon observation, is reduced to a single eigenstate, we call this the wave function collapse. Thus, the MWI, denies the actuality that the wave function collapse even happens. In the Many-Worlds interpretation, each of these possible observations, corresponds to a different universe! In the Level III multiverse, all possible histories, futures and realities are real. Anything that could have happened, and did not, did happen, in another universe. A good way to visualize the many-worlds interpretation is by throwing a die. There are 6 possible outcomes, you role a 1, 2, 3, 4, 5 or a 6. One of these will be observed in our physical universe. However, if the many-world's interpretation is correct, than, each of these possible outcomes, corresponds to a different universe, that exists on a quantum branch, in infinite dimensional space. 

A way to visualize the Many-Worlds interpretation. Each possible outcome, has a corresponding universe, each equally real.

The MWI is an interpretation of quantum mechanics where, each potential outcome to an observable in a quantum system will actually reside in different universes, that somehow coexist.
