Sombra del Universo is a visual journey through the hidden macrocosm accompanied by a poetic voice. Ninety-seven percent of the matter that makes up the universe is dark matter. This matter holds secrets related to the origin of the universe, appearing in various forms such as dark stars, filaments, nebulae, or galaxies. The abstract imagery allows us to reconstruct and imagine the meaning of the photographs from our own subjectivity. Departing from a scientific discourse that seeks truth and objectivity, this photo book celebrates the intuition and imagination that arise from shadows and dimly lit places.
