What does the king of the infinite universe in the shell mean?

Being in a shell means that even if I am locked in a shell, I still think I am the king of the infinite universe. This sentence is not arrogant, nor is it a compliment. It's just a self-complete sentence.

This sentence was written by Shakespeare, and Hawking wrote his masterpiece "The Universe in the Shell" on this topic. Wheelchair is his "shell", but Hawking, trapped in his body, still has the universe in his mind, shaping the modern world view and leading millions of people to look into the vast distance.
