How Black Holes Define Entropy’s Cosmic Limit
Entropy, the measure of disorder or information content in physical systems, lies at the heart of thermodynamics and statistical mechanics. It governs how energy distributes across states, reaching a maximum only under precise limits. Fundamental physics suggests that entropy cannot grow without bound—there are cosmic boundaries that define its ultimate scale. Black holes, as the universe’s most extreme gravitational objects, exemplify this limit by encoding entropy within a finite surface area, far exceeding any classical system. This principle reveals a profound link between gravity, information, and the thermodynamic horizon of the cosmos.
The Concept of Entropy and Cosmic LimitsEntropy quantifies the number of microstates corresponding to a system’s macroscopic state.
