Final answer:
The notion of a complete theory being understandable by everyone intersects with the complexity of theoretical physics, but efforts are made to simplify and communicate these ideas to a broader audience.
Step-by-step explanation:
The notion that a complete theory should be understandable by everyone intersects with the inherent complexity of theoretical physics, particularly in the context of understanding the origins of the universe and consciousness.
Physics, especially in the realm of quantum mechanics and general relativity, involves intricate mathematical concepts and abstract theories that can be challenging to comprehend. However, scientists strive to simplify and communicate these ideas to a broader audience through popular science books, documentaries, and educational platforms.
