A Brief History of Time mainly introduces to people what cosmology is and the development of cosmology in popular language, answers many basic questions about the universe, and allows people to understand the universe in more detail, becoming a major work of the 20th century.

Co-authored by Stephen Hawking and Leonard Monlodino, the author uses new physical theories to explain the fundamental questions about the universe, and for the first time introduces the complex physics of the universe to the general reader in a very easy-to-understand language. Continuing Hawking's usual clear and witty writing style, the book presents readers with a compelling story that explores the core secrets of time and space.

The subtitle of this book is from the big ** to the black hole. Hawking believes that his life's contribution is to prove the inevitability of black holes and large singularities within the framework of classical physics, and black holes are getting bigger and bigger; But in the framework of quantum physics, he pointed out that black holes are getting smaller and smaller due to radiation, and the big singularity is not only smoothed out by quantum effects, but the entire universe starts here.

A Brief History of Time is a book about the universe, as well as the relationship between space and time and some things about what the universe will look like in the future and the loopholes in space, which prove the inevitability of black holes and the big singularity, black holes are getting bigger and bigger.

About the universe of big ** and black holes.

Write about physics, about the universe.

1. The starting point of time, the great singularity of the universe. The universe is constantly expanding, and it should initially shrink to one point, and this moment is called the great moment of the universe. The density of the universe at this point is infinite, which is called the singularity in mathematics;

2. The end of time, black holes. Stars shrink due to gravitational attraction and form a "black hole" that is not bonded. The gravitational attraction of the surface of the black hole is very strong, and time will end here;

3. How God activates the universe, the origin and destiny of the universe. One is the origin of the universe called the disordered boundary condition, explained by the anthropic principle; Another explanation, called the "inflation model," holds that the universe expands at an accelerated rate at the beginning of the moment, and that the radius of the universe increases by 100 trillion trillion times in much less than 1 second;

4. The unity of physics, the ultimate theory. Mankind is seeking to establish a complete, coherent and unified theory for every event in the universe, in which there is no need to pick specific constants to conform to the facts.

A Brief History of Time is a scientific work by British physicist Stephen Hawking, first published in 1988, with 12 chapters, all of which deal with the most cutting-edge knowledge about the nature of the universe.
