Dark matter in Actor-Network Theory context (La materia oscura en el contexto de la teoría del actor-red)

The aim of this work is to use some categories of Actor-Network Theory (ANT) developed by Bruno Latour in the book Reassembling the Social -- An Introduction to Actor-Network Theory to analyze a current controversy that occurs in the area of cosmology: the dark matter existence and its characteristics. The central idea of this article is to try to decipher which type of agent is the dark matter and open the discussion about this topic from a sociological perspective.
