According to the use that is given to it, the word sunset it can refer to different things. The most widespread use is that which refers to the sunset is the sunset or some other star. Because a star, especially the sun, will be at sunset when it crosses the horizon plane and goes from our visible hemisphere to the non-visible one, when its height is zero and goes from positive to negative.
In the case of a star like the sun, sunset will mean the end of the day, meanwhile, the opposite situation, which is opposed to this state is that of sunrise or also known as dawn, which is when, for example, the sun appears on the horizon and a new day begins. It is worth noting that the only stars that have neither sunset nor dawn are the circumpolar stars.
Modifications during the equinoxes
As the year progresses, the sun will change where it sets. During the equinoxes, that moment of the year in which the days have the same duration as the nights in all the places that make up the planet earth, the sun sets in the west, being the only two days of the year in the which this phenomenon occurs. This phenomenon occurs as we said twice a year, on March 20 and September 22, which is when the two poles of the earth are at the same distance from the sun, sunlight falling in the same way from both. sides of the hemisphere.
Meanwhile, in spring and summer in the Northern Hemisphere the sun sets between the west and the north, which is known as positive declination. Simultaneously, in the southern hemisphere it is autumn and winter, sunset between the west and the north or spring summer, which will be the sunset between the west and the south.
The refraction that the sun's light rays produce in the atmosphere causes us to see light when the sun has already set, the so-called evening twilight. This phenomenon will lengthen the day and shorten the night.
Too, the west or cardinal point is usually designated with the term of sunset.
It should be noted that sunset has a very characteristic hue that makes it visibly recognizable: a pale orange color, which is precisely the one that prevails when sunset.
The twilight understood as decadence
And on the other hand, When you want to account for the decline, the loss of importance, value or strength that something or someone held, it is usually designated as decline. For example, when an artist has lost all that magic and imprint that characterized his works as unique, it will be said that that artist is in the twilight of his career.
The aforementioned is a very common situation in which famous people who have excelled in some subject or art can fall. There are so many cases of authors, actors, musicians, who despite having reaped a highly appreciated career, with succulent successes and recognitions, at a certain point in their lives and for some very specific reason, end up losing part of that recognition.
In the case of artists and authors, it has been a constant throughout history that the fall in addictions such as drugs and alcohol makes their professional lives become unproductive, simply because addiction dominates them and then already They do not produce as before, they are not so lucid as to do the great things that they have been doing.
Also this sense of sunset is very common to appreciate on the political level. In political history there are precisely many governments, powers, which at a certain point were known to be the most powerful in the world of their time and then, either because another group surpassed them in some aspect, or a certain serious event happened, they end up losing that power. tremendous that at some point they incarnated, falling into an agony of authority that little by little will make them disappear.
For this reason, the concept of decline in this sense is linked to the loss of strength or authority.
