The Universe might be a finite quantum system, like a hard drive with limited storage. But any observer inside it can only 'read' a tiny slice of all the information. So even if a perfect 'theory of everything' exists, we can never test it fully—a fundamental limit of knowledge is baked into the laws of physics.
🎯 If the Universe is a book with a finite number of pages, its total entropy (a measure of uncertainty) is like the maximum number of letters. That's why scientists speak of a 'digital' footprint of reality.
🎬 The metaphor of a book with unreachable chapters comes from Borges' story 'The Library of Babel'—where characters seek an absolute book, doomed to eternal incompleteness.
