Concept in Definition ABC

There is talk of gloom when in the environment in question there is a weak shadow between light and darkness and that at first glance prevents us from seeing where one begins and where the other ends. “The house is in darkness, please can you turn on some light. Dinner with Mario was the most romantic, we had dinner in a restaurant that looked out to the lake and presented lighting with a predominance of twilight.”

Weak shadow that does not allow to identify things and people well because there is no full light

Although for many people the gloom tends to cause fear and displeasure, and for example they want to get out of it, either by leaving that semi-dark place or by turning on some light that I took them out of it, we cannot ignore that for some people and contexts the penumbra is presented as an excellent option to find privacy, especially in cases such as the one indicated in the example of lines above, of a dinner or romantic meeting between two lovers where the little lighting, that is, the semi-darkness, invites the privacy that many times

demand the love.

Technically, in a twilight setting, the light source is partially blocked, unlike in the dark, in which the light source is totally blocked. It is because of this difference that in the semi-darkness we can see some areas of light, shapes and colors, although, not entirely clear, that is, the semi-darkness is never total darkness.

For example, if the living room of the house is in twilight and someone is on the sofa resting, it is possible that we notice that there is a figure lying on it, however, we will not be able to distinguish who it is, since the semi-darkness does not allow us to notice details significant.

While the lunar eclipse is a event What will happen when the earth comes between the sun and the moon causing a cone of shadow that will darken the moon. For the eclipse of these three bodies to occur, their alignment is necessary.

Eclipses can be anticipated through the use of the technology, with computer programs designed to accurately calculate the positions of the bodies and then draw the conclusions that inform us of the dates of their succession.
And an ancient form that is the annotation of the cyclical repetition of these phenomena.
