This book is a popular science model of physics, telling the special relativity and cosmology of time and the origin of the universe.
brief Introduction of the content
Admitting the mistake of "black hole paradox", in July 2004, Hawking revised his original view and admitted "information conservation".
Cosmology is an ancient and young subject. Therefore, as a higher creature in the universe, human beings are not satisfied with their own survival and the extension of race, but are still tirelessly exploring the significance of the existence and life of generations. However, the evolution of human thought is extremely slow and arduous. From Aristotle to Ptolemy's geocentric theory to Copernicus' Heliocentrism, it has evolved for 2000 years. Surprisingly, although people know that everything in the world is moving, it was not until Hubble discovered the law of red shift in the 1920s that the concept of the evolution of the universe entered human consciousness. People never even thought that the universe would evolve. Newton's law of universal gravitation shows that the matter in the universe cannot be in a stable state under the action of gravity. Even in Einstein's general theory of relativity, the situation is not much better. In order to get a stable model of the universe, he introduced the cosmological constant into his theory. They all hope to find a stable model of the universe in their own theories. It can be seen that the concept of the evolution of the universe was not produced in the minds of these geniuses.
