Everette's many worlds interpretation of the mathematic constructs of Quantum Mechanics may have shocked the world of physicists in the mid 20th century. Some might have even called it blasphemous. Such un-Copenhagen view of the real world is really derailing itself from reality, or is it? In Quantum Mechanics, existence of matter at any locality is described by its wave function, essentially assigning probabilities to various points in space, probabilities of the matter existing at particular points. How unrealistic a description it is of the macroscopic world we reside in. Are we not, in actuality, existing at the very point where we are existing right now? I do not see the Eiffel tower and the Nil river at the same time, nor do I see one, then instantly the next. In Copenhagenists' term, the wave function has collapsed. Collapsed by observation. The chair on which you sit, may have been on the Moon, or on Alpha Centauri; but because your sensory has come to observe it, its wave function is instantly collapsed, resulting in it appearing with 100% probability right where it is, right now. We do not observe the chair in many places at the same time. However, in the microscopic world, this phenomena is very real, and even more than ever present. Why, Everette thought, should this ever be the case? Why should there be a need of "collapsing" wave functions? Why should there be a demarcation between the macroscopic and the microscopic world? Where does this imaginary boundary lie? Is it a necessary part of Quantum Mechanics? Or is it just an illusion, a case of ignorance, demonstrating the fact that we do not fully comprehend what does this peculiar behavior mean in our own world, in our own terms? Why can't they all exist at once, albeit in their very own reality, unaffected by the other? If this is true, then, what is the implication? Many different worlds, indubitably. Each one branching off a fork amongst many other forks in an ever growing tree of realities. No collapsing needed. No unnecessary boundaries between the macroscopic and the microscopic. All is well.
If so, could we not imagine, in a universe, something, of some form, appearing out of nowhere for no reason, and with no trace of its origins? After all, given the unlimited bounds of space and time dimensions, that which is probable, however slightly, comes to transpire, sooner or later. Suppose, for the purpose of dramatization, an entire civilization, which is more than sufficiently advanced, appears out of nowhere. This civilization possess the knowledge of the intricacies and mechanisms by which the universe, or rather, the multiverse contains, and runs. They possess the mastery of matter and non-matter, and also of life and mortality. They are so powerful relative to the present stage of Mankind, that they are effectively God-like. Their motives, rationale, moral, ethics, consciousness, thought process, so different, so highly evolved, that they are no longer comprehensible to us mere mortals. These properties, when carefully mulled over, are really not all that hard to attain. Humankind, at its ever increasing rate of progress and advancement, shall come to a point in time where it becomes transhuman, and thus no different than the fictional civilization I proposed, capability-wise. This point is called The Singularity. The point thereafter humans are imbued with capabilities incomprehensible to our present mind. However, there still remain one thing that sets us apart from the said fictitious civilization. They do not have a history. They appear out of nowhere, for better or worse, all thanks to the quirks of Quantum Mechanics.
