Ever since Thomas Aquinas two kinds of Infinity can be differentiated: „in-finitum" as a negatively defined and material infinity in comparison to „aeternitas" as the categorically higher true infinity which is exemplified only by god. This differentiation is often used to explain disparities between the immanent perspective of human beings and the transcendent perspective of god. This concept allowed many philosophers and scientists to work with the concepts of infinity in regards to the universe and aside from god. Chief among them is Giordano Bruno, who could develop his theory of an infinite universe as a mirror of god's infinity. However, besides those two conceptions other philosophers have to spearhead new conceptions of infinity to fit their Systems. On one hand Descartes' concept of an unknowably big universe for example skirts the line between the conceptions of a finite and infinite universe. On the other hand, thinkers like Kopernikus, Keppler and Galileo conceptualize the universe as infinite without regard to how this reflects on the infinity of god. This presentation should present a select group of philosophers of the early modern period and showcase their work with infinity in respect to the conception of the universe. In this manner the nuanced relationship between the terms universe, infinity, perspective and god. The main Philosophers that will be discussed are Thomas Aquinas, Giordano Bruno, Galileo Galilei and René Descartes covering mainly the arguments in respectively Civitas Dei, De L'infinito, the Dialogo as well as the Principia and Le Monde. Of course, a point of the presentation is to highlight the discussion of shifting discourses besides the main discussion of the specific philosophical arguments concerning infinity god and the universe
