Episode 740 - Cosmic Conundrums

The historical trajectory of theoretical physics is marked by a deep ontological tension between absolutist and relational conceptions of space, time, and motion. This debate was famously crystallized in the early eighteenth century during the correspondence between Gottfried Wilhelm Leibniz and Samuel Clarke, who acted as the spokesperson for Isaac Newton. Newton postulated that absolute space is an infinite, immutable, and immovable substantival container that exists independently of any physical matter, serving as an unchanging backdrop for the dynamics of the universe. In contrast, Leibniz rejected this substantivalist view, arguing that space is not an independent entity but rather an abstract "order of coexistences," while time is an "order of successions".
