17th and 18th centuries cosmology
Abstract...
The structure, formation and evolution of the Universe were some of the main topics in the scientific debates during the 17th and 18th centuries in Europe. They involved novel ideas on the cosmos, which concerned aspects that were not considered before so emphatically, and which were fundamental for the future development of astronomy. This paper presents a brief account of several milestones within the gradual definition of pre-galactic systems: the historical role of the tradition of the plurality of worlds, the significance of Descartes, and the introduction of the Milky Way and nebulae in the discourses around the cosmic structure.
