The two worlds interpretation

The two worlds interpretation from my book "The Big Defreeze of the Universe - Analogies & Thought Experiments" 

To help understand the idea of the two worlds interpretation and how it could be a good candidate for a solution for the measurement problem, we will go back to the notebook thought experiment introduced earlier in this book.

The analogy goes that we have a notebook of let`s say 120 pages of holographic two dimensions films. These 120 pages would be representing our multi-verses, so all the possible universes are within this notebook including our universe.

If you look at the two-dimensional holographic page of our universe, you would not be able to tell what this thing is a hologram of, unless you shine a light on it to see the three-dimensional representation of reality of this holographic film. Technically, you are outside the space-time of this holographic film and probably you are not governed by the laws of this holographic film including the laws of quantum mechanics, and you would be shining light from outside it.

The idea is simply that we have two worlds. One in our universe on that two-dimensional holographic film having quantum mechanical behaviors and the other one is totally outside “the notebook” (our universe or multiverse) and its space-time parameters. It does not follow the quantum mechanical behavior.

The version of you in our universe is an observer with constituents following the quantum mechanical behavior, which requires the second version of you in the other world with constituents that do not have quantum mechanical behavior.

Even if the idea of the multiverse is eventually proven correct, according to the proposed two world interpretation the multiverse will not necessarily imply that there are many versions of you doing all possible scenarios. The two worlds interpretation suggests that there is only one version of you acting as an observer with constituents that do not have quantum mechanical behavior. The second version is acting as an observer of the first version. But the second version does not require an observer because its constituents do not have quantum mechanical behavior.
