Hello and welcome back to our regularly-scheduled lies here at Factually Deficient! This week, I will answer a question posed by the one and only Blurred_9L, who asked:
Who is on the other side of the line?
Now, the line in question is, of course, a line of symmetry. In order to understand who is found on the other side of a line of symmetry, we must understand two things: what symmetry is, and which particular line we are looking at.
Symmetry, outwardly, is often described as a mirror-image relationship. This is incorrect. Symmetry actually refers to a type of quantum entanglement, whereby a large set of particles each occupy two places at once, arranged along a straight, horizontal or vertical axis in a manner resembling a mirror-image. Symmetry does not describe two things that look alike, but rather, one thing that appears doubled.
As for the line Blurred is referring to, there can, of course, only be one line of symmetry that so obviously has a “who” question referred to it: the spinal column.
On most, if not all, human bodies, the spinal column functions as a line of symmetry, along which a human body (which is actually only half of what we commonly recognize as being a human body) seems to mirror itself, thus creating the illusion of humans as having two eyes, two ears, two arms, two legs, two nostrils, etc. This is also why any injury to one of any of these appendages is generally felt in the “other” one, as well – because in fact, they are both one and the same.
In short, and in summary, to answer Blurred_9L’s question of who is on the other side of the line (of symmetry): you are.
