From Latin impossibilis, impossible is what is not possible or that results of very difficult compliance . To understand the notion of impossible, it is essential to know the definition of possible .
The possible is what can be, happen or exist . The concept is associated with real or what plausible : It is possible for a dog to bark at night or rain tomorrow on a Caribbean island. The impossible, however, It has no chance of materializing or, at least, it is more than difficult. Thus it can be said that it is impossible for a cat to bark or to snow tomorrow on a Caribbean island.
What is impossible can change with the weather . In prehistory, it was impossible to think that a human being would fly, something that became possible from the invention of the plane. Today it is impossible to think that people can travel in time but, perhaps, in the future such action will be achieved from some technological innovation.
Sometimes, the impossible is associated with known conditions or at existing evidence . Thus some may claim that it is impossible for the Yeti to exist although, in reality, for others it could be possible for such a creature to inhabit land unexplored by the man . In this way there is an opposition between the impossible (there is no possibility that the Yeti exists) and the possible (there is minimal probability that said being will live on Earth and has not yet been found).
In colloquial language, the impossible adjective is used to name something difficult to accomplish : "Cristiano Ronaldo scored an impossible goal by eluding five rivals and kicking the goal from a very awkward position", “The Canadian runner won an impossible race: he started in the last position and managed to beat a competitor every two laps ”.
The terms impossible and improbable are often confused, as well as their opposites, possible and probability. However, if we refer to the dictionary of the Royal Spanish Academy, its meanings are sufficiently different: impossible is a situation that has no power or means to succeed or become; improbable, on the other hand, is an unlikely thing that has no basis in a prudent reason.
In other words, something unlikely can happen, although a analysis Rational cannot guarantee it or point to not expecting it to happen. This concept can be applied to various cases, from sports confrontations to the sale of a property, through job search: "It is unlikely that my favorite team wins, but I don't lose hope", "Given the economic situation, it is unlikely that this house will be sold", "With this curriculum it is very unlikely that I will be given the position".
For newly exposed situations to be considered impossible, they should exist factors force majeure that prevented by all means its success: that the team be forbidden to play, that the house has been ruined because of an earthquake and that the person applying for the job has a considerable criminal record and knows that The company will provide such information before making its decision.
As mentioned in previous paragraphs, the limits of the possible and, therefore, of the impossible are often given by historical questions and culture, so they are not considered rigid. Just as the technological advances of the last three decades have given us devices and communication networks that seemed impossible half a century ago, also at the ideological and cultural level, changes that many believed unattainable have been achieved, although in these cases the growth is much slower .
