Abstract
This paper examines the transformation of the concepts of physical quantities and reality within the framework of quantum mechanics, with a particular focus on the philosophical shift from a materialistic universe rooted in classical local realism to an information-theoretic universe based on quantum theory. Classical physics, grounded in local realism, assumed that physical objects possess intrinsic properties independent of observation. However, quantum mechanics challenges this view, suggesting that physical quantities might not be attributes of physical objects, particularly in light of phenomena such as quantum entanglement and the violation of Bell's inequality. Building on John Wheeler's ``It from Bit'' hypothesis, this paper argues that `It' emerges through informational processes, where the observer, the measuring apparatus, and the observed system interact. This shift in understanding critically examines local realism, rooted in philosophical foundations, in light of the empirical demands of quantum mechanics, leading to an interpretation of reality as `reality', an emergent phenomenon shaped by measurement and based on information. By reconstructing physical quantities within the framework of algebraic quantum theory, the paper highlights the necessity of moving beyond traditional philosophical debates and embracing a more relational and dynamic view of the universe.
