This text explores the philosophical nature of physical constants within the context of a universe where everything appears to be in flux. The author challenges the traditional Aristotelian view, which posits that change is only possible upon a fixed, unchanging substrate. Instead, he proposes an ontological shift: change itself is fundamental, while what we perceive as permanent or stable is actually the result of an active organization of variability into repetitive structures of events. Thus, permanence is not a given starting point but an achieved state of controlled dynamism. Despite this primacy of change, scientific descriptions of the world consistently rely on constants. The author raises the question of whether these constants are merely instrumental tools within mathematical frameworks or if they possess a genuine ontological grounding in reality, as theoretical physicists maintain. This reflection invites a deeper inquiry into the relationship between mathematical models and the inherently processual nature of existence, which often defies static categorization.
