In this work, it will be shown that the gravitational field equations, described by the theory of general relativity, and the equations describing textures in nematic liquid crystals are surprisingly similar; it is possible to formulate the principles of both field equations using alike statements, leading to the establishment of a detailed correspondence between many of their aspects. As a consequence, the textures of nematic liquid crystals can be described by an Einstein-like equation, where the elastic-stress tensor replaces the energy momentum tensor, and, moreover, some aspects of the geometry of the gravitational field can be simulated in a nematic sample.
