The word singularity, in its strictest sense, refers to the quality possessed by those people, objects or facts, called singular. From this, it can be said that singularity, as a determining factor, are those characteristics that distinguish a certain entity from those of its same class or group. Within mathematics, the term is used to talk about those functions that, once their value is discovered, begin to behave in an unexpected way; that is why the singularity theory was established. In physics, for its art, you have the gravitational or spacetime singularity, an astrophysical model in which the curvature of space-time becomes infinite, as shown in some of the black hole models.

In mathematics, singularities can be quickly identified. These, according to their nature or the characteristics they present, can be both essential, that is, their behavior is extreme, and isolated, those that do not have singularities close to them. In physics, following the line of spatio-temporal singularities, theorems have been created, such as the Penrose-Hawking theorem, in addition to the mechanical singularity theory, where the behavior of any mechanism, which presents a certain configuration, it cannot be predicted, or its magnitudes become infinite or indeterminate.

Within the philosophical field, we speak of the singularity of entities, that is, the particularities of each existing being. This is studied in ontology and is also presented in Christian philosophical doctrines. Similarly, there is talk of a technological singularity, a hypothesis in which it is proposed that, at a certain point of progress, a certain technological civilization would be unable to control the consequences of such benefits.
