Wikipedia’s mixing up metaphors and referring to an alternate reality as one and the same thing as a parallel reality.
They are most certainly not one and the same thing.
Now wikipedia is a publicly sourced encyclopedia, and wiki editors, in my experience, are, quite frankly- bastards, so before I actually create a wiki entry – I want to make sure it’s absolutely bullet proof.
So consider this a start of my unfolding definitions for an alternate reality.
An alternate reality is a separate and distinct version of our fact based version of the world where the laws and rules that govern that version of the world do not necessarily adhere to the the same rules and laws that govern our own.
An alternate reality can be a historically altered and/or inaccurate version in comparison to that of our own reality.
An example of a depiction of this type of alternate reality would include the events depicted in the fictional movie “Terminator 2”, where robots and androids are at war with humans for world domination after a nuclear Armageddon was initiated by an artificially intelligent lifeform named “Skynet ” on August 29, 1997..
This movie depicts events which can be classified as fiction, or to provide a more accurate classification which would be in support of the concept of multiple universes, a more accurate categorization would be to refer to it as an alternate reality.
Alternate realities can also be used as a classification for simulation and intellectual discussion – to answer historically inaccurate ‘what if’ questions such as “What if JFK did not die” or “What if the Twin Towers were never attacked?”
There is no current classification system other than the wildly misused fact vs fiction, which has historically seen a great deal of abuse and corruption due to revisionist historians such as those interested in personal gain.
An alternate reality can also be defined as a perceptually altered reality where the physical laws and psychological laws that govern hat reality can be remarkably different than our own.
With the negatively connotative classifications such as “Hallucination” and “Vision”, a more scientifically acceptable term to use for the act of perceiving worlds outside normal space and time would be to refer to these occurrences as “Seeing an alternate reality”.
Movies such as “John Carter” depict a world where the laws of gravity would work remarkably different than they do on Earth.
This world and many worlds like it quite likely do actually exist.
However, If one were to create a simulated world with the same laws of gravity, one would refer to this simulation as an alternate reality.
Viewing the ‘fiction’ on the television screen and movie is not the same as being in the physical location itself. Accordingly, it can also be said this view is of an ‘alternate reality’ to circumvent the stigma associated with the label ‘fiction’
Conversely, if one were to physically visit the planet under simulation, it would be referred to by it’s normal designations.
The term alternate reality in this case allows the differentiation between simulative fiction and the real life worlds they depict.
Video games, with the laws of gravity, and the laws and rules of those governing a population within a video game – can also be considered ‘alternate realities’.
Evidence is being found to suggest that some video games are actual alternate realities and worlds.
To leverage this term is to suggest that this area of scientific exploration may need to continue, and that it cannot be readily proven nor disproven that this reality contains sentient self aware life.
An alternate reality is merely a label to reframe the consensus based psychology which has compartmentalized fiction as definitively not real thus placing artificial and arbitrary constraints on the continued scientific exploration of these potentially life bearing worlds.
A parallel reality would be thought of as having a high degree of likeness to the reality in parallel.
That is, a parallel reality is an alternate reality. But not all alternate realities are parallel realities.
A mirror reality is thought of as having generally opposite values as the reality in comparison.
In Star Trek, the mirror reality population depicted was perceived as being dark and sinister in contrast to the generally more laid back original reality.
Again, a mirror reality is an alternate reality, but not all alternate realities are mirror realities.
A ‘dimension’ is a rather confusing term, there are MANY different and opposing definitions for it, so classifying this with any accuracy will take an act of god.
,… that’s just my current two cents on .
