Bekenstein Bound

The Bekenstein Bound is a theoretical limit on the amount of information or entropy (disorder) that can be contained within a finite region of space holding a given amount of energy. Essentially, it suggests that there's a maximum information capacity for any physical system, proportional to its energy and size. This concept links gravitation, quantum mechanics, and thermodynamics, implying that the universe's information content is finite and governed by its physical properties. It helps us understand fundamental limits of data storage, black holes, and the nature of information in the universe.
