A question mark is a punctuation symbol used at the end of a sentence to indicate uncertainty. The question mark symbol is shown in the picture below.
Why is that particular symbol used to indicate uncertainty? Any symbol imaginable could have been chosen as the punctuation mark to indicate uncertainty. Why choose that exact symbol?
According to Happeh Theory, that specific symbol was chosen because that shape instills a feeling of uncertainty in any human being, when they see it in the head of another human being.
Why or how is it possible that one human being could see the shape of a question mark in the head of another human being? The head of a human being has an irregular, mostly elliptical shape as shown in the next picture.
According to Happeh Theory, the human body at a deep level is constructed from a variety of patterns that are meshed together to form the human body that is seen in a picture or a mirror. According to Happeh Theory, an imbalance between two of those patterns can change the head so it gives the impression of having the shape of a question mark.
The following picture shows the entire human body with a low detail representation of the two patterns in question superimposed on it.
The next picture shows a close up view of the head with a detailed view of the route of each of the two patterns superimposed on it.
Each pattern begins at the base of the neck and travels over to the opposite side of the neck,
then up to the base of the skull on the opposite side of the head,
Each pattern then travels all the way up their respective side of the head,
and then crosses over the top of the head to the opposite side of the head.
Each pattern then travels down the opposite side of the head to the outside corner of the opposite eye,
where each pattern curves all the way under their respective eye towards the inside of the eye,
and up into the inner corner of that eye.
If the part of each pattern under the eye is removed,
the red pattern looks like a question mark symbol
and the blue pattern looks like a question mark symbol.
In a normal and healthy human head those two patterns should be balanced. The symmetry of the two balanced question mark patterns would give the head and face a “complete” or balanced appearance.
Those patterns can change size. If the red pattern shrank until it was very small in some example head,
that head would give the impression the example human beings face was shaped like the blue question mark.
If the blue pattern shrank until it was very small in some example head,
that head would give the impression the face of the example human being was shaped like the red question mark.
If an observer were to look at a human being whose head and face gave the impression they were shaped like either the red or the blue question mark,
what would they would think?
The observer would be confused and uncertain as to where the other half of that human beings head and face were.
According to Happeh Theory, that instinctive reaction of any human being is why the question mark symbol was designed the way it was. The person who invented the question mark punctuation symbol, knew that any human being who saw a question mark punctuation symbol would instinctively understand it meant uncertainty or confusion, because it would remind them of the uncertainty and confusion they feel, when they see a question mark shape in the head and face of another human being.
