The concept of entanglement in quantum mechanics is not just a theoretical curiosity; it has profound implications for our understanding of information and causality.
The interplay between quantum mechanics and general relativity is one of the most profound puzzles in modern physics, and solving it may require a complete rethinking of our understanding of the universe.
In the quest to understand quantum gravity, we are like children playing on the shore of a vast ocean, occasionally finding a smooth pebble or a pretty shell, while the great ocean of truth lies undiscovered before us.
