Stephen Hawking's works are mainly scientific in nature. They deal with concepts like the nature of black holes, the theory of relativity, and the origin of the universe. Novels, on the other hand, are fictional stories. For example, Hawking's 'A Brief History of Time' is about real scientific phenomena, while a novel could be about made - up characters and events.
Stephen Hawking's works are centered around physics, cosmology, and related scientific fields. They are meant to convey accurate scientific knowledge. Novels are a different genre altogether. Novels can cover a wide range of topics from historical fiction to fantasy. Hawking's books are more like textbooks in a sense, but made accessible to the general public. For example, his works might talk about the expansion of the universe, whereas a novel could be about a detective solving a mystery in a small town. There is no creative fictional narrative in Hawking's works like there is in novels.
