Quantum Computing: Parallel Universes (Revisited)

Every denizen of this planet has encountered this phrase at least once: "Your life is the partial expression/partial product of the choices you made from the time you were conceived up to this present moment". Conversely, it also holds that: "Your life is the partial expression/partial product of the choices you didn't make from the time you were conceived up to this present moment".

...This may seem like an astute play of words, but this example will illuminate on what I mean:


On a planet located in a distant galaxy that is 124 light-years from the Milky Way, there are only two distinct species of intelligent beings: Zoogles and Boogles. Zoogles are different to Boogles and, in fact they can be regarded as extreme opposites. Zoogles don't commingle with other Zoogles, and Boogles don't commingle with other Boogles. The inhabitants of this weird planet hang out in pairs (a Boogle and a Zoogle), with their perfect opposites. Hence, this means that any being you encounter on that weird celestial body is either a Zoogle or a Boogle. Which, therefore, implies that a Boogle is any randomly selected intelligent being on the planet who is not a Zoogle, and vice-versa.

Let us postulate that the distant planet is the multiverse, or grand universe of the totality of choices you could ever make, and couldn't/didn't make in your life, and that the universe, or subset illustrating the choices you actually managed to make is represented by the Boogles, and that the choices you didn't or couldn't make are represented by Zoogles.
If someone knew every single Zoogle on this planet, and knew their individual character traits, he/she could work out the individual character traits of all Boogles, without even meeting a single Boogle (remember: Boogles are the extreme opposites of Zoogles), but then he'd/she'd be still left with the task of appending the character traits he/she arrives at, to individual Boogles. If he/she had additional information on Boogles and Zoogles that associated which each other, the task of appending the character traits he/she arrives at, to individual Boogles becomes easier. Therefore, the example simply serves to illustrate how an object can be abstractly constructed, when information on the particular object is lacking, from information on its perfect opposite. Hence you can see why it is also true that: "Your life is the partial expression/partial product of the choices you didn't make from the time you were conceived up to this present moment."

More on choices: Everyone has a specific choice they made, that changed the course of the rest of their lives. For Bill Gates, his life-changing choice was to create software called BASIC for the MITS Altair 8800 - which, in essence, laid the foundations for Microsoft: a company that made him a billionaire.

If Bill Gates hadn't decided to create software for the MITS Altair 8800, what course would his life have taken? Would his life be like what is right now?

Of course it wouldn't, it would have taken a totally different course. That is in essence, what the term 'parallel universes' in quantum computing seeks to describe - different future 'realities' that a particular organism would find itself immersed in--or different realities it would experience--because of minor variations in the organism's present and past environmental circumstances (that may/may not be partially shaped by the choices the particular organism makes). These different realities are as infinite as the choices an organism makes during its lifetime, and are termed parallel universes in quantum computing terminology.

Makes sense now?
