A brief history of time, a brief history of everything. The sequel to A Brief History of Time is the undisputed authority of cosmology. Hawking's research achievements and life have always attracted readers. The sequel to A Brief History of Time is for readers who want to know more about Professor Hawking's life and his theory. This book describes the life course and research work of Professor Hawking's A Brief History of Time in the form of wise and sincere personal interviews, and shows the true humanity behind the huge theoretical framework. This book is not an ordinary oral history, but a very touching and charming portrait and description of one of the greatest thoughts of mankind in the twentieth century. For non-professional readers, this book is undoubtedly beyond their understanding and can only be read as science fiction. Hawking's Lecture-Black Hole, baby universes and Others is a collection of articles and speeches written by Hawking during1976-1992 * *13. This paper discusses the virtual space, black holes leading to the birth of baby universes, and scientists' efforts to seek a completely unified theory, and puts forward original opinions on free will, life value, human survival mode and evolution principle. In A Brief History of Time, Hawking is obsessed with the theory of grand unification, which is Einstein's unfinished dream. Hawking admits in this book that everything in the universe cannot be described and predicted by a single wonderful formula, because the uncertainty principle of quantum theory determines that the universe is the unity of uncertainty and certainty. In this book, Hawking uses a map model to show that the diversity of the universe may need to be described by a family of theories. The essence of space-time was expressed in a complete mathematical form 80 years ago, and the basic principle of quantum theory (he personally thinks that it is only the smallest unit of theoretical physics at present) appeared 70 years ago. However, can these two most accurate and successful theories in the whole physics be unified in a single quantum gravity? Two of the most famous physicists in the world have launched an extreme and extreme debate on this issue. This book is based on six speeches and final debates given by Hawking and Penrose at Cambridge University. The charm of the future begins with stephen william hawking's prediction of the next billion years of the universe and ends with Don Kubit's understanding of the final judgment. It introduces the development of prediction and the methods we use to predict the future today. The words in the book are easy to understand. The author expounds his own views and answers some interesting questions. The Universe in the Shell is Professor Hawking's most important work after A Brief History of Time. In this book, Professor Hawking once again takes us to the forefront of theoretical physics. In Professor Hawking's world, truth and fantasy are sometimes just a thin line. Professor Hawking's explanation in popular language reminds us to fully imagine the universe, and with his unique enthusiasm, invites us to launch an extraordinary journey of time and space together. A Brief History of Time-From BIGBANG to Black Hole (written in 1988) is Hawking's masterpiece. The author's imagination is rich, his ideas are wonderful, his language is beautiful and his words are meticulous, which is even more surprising. Outside the "world", the future changes are so magical and wonderful. This book has a cumulative circulation of 25 million copies and has been translated into nearly 40 languages. In this book, Hawking will try to outline the history of the universe in our mind-from the Big Bang to the black hole, and organically combine various religious theories. In the first lecture, he will briefly review the past ideas about the universe and explain how we get the current image. This may be called the history of the universe. The second lecture will explain why Newton and Einstein's two theories of gravity lead to the conclusion that the universe cannot be absolutely static, and it must either expand or contract. This in turn means that between the first 20 billion years and the first 654.38+0 billion years, there must be a moment when the density of the universe is infinite or out of a certain space, resulting in the so-called Big Bang. This may be the beginning of the universe. The third class will talk about black holes. Black holes are formed when a giant planet, or a larger celestial body, is attracted by its own gravity and collapses (collapse and contraction) (another guess: black holes are separated from elements in a set space). Based on the theory of perceptual philosophy, "everything will go from one extreme to the other under the baptism of time and space", which may be the cause of the white hole. According to Einstein's general and special relativity, there may be countless black (white) holes in the universe (or the world we live in is a branch of black (white) holes). And their history may be the end of a certain field or just a new beginning, because the more you know, the more you find that what you know is just the tip of the iceberg. The generalized (narrow) theory of relativity is a classical theory (because there is no absolute ideal state in this world), including the uncertainty principle of quantum mechanics. The fourth lecture will talk about how quantum mechanics makes energy leak from black holes. Black (white) holes are not as terrible as people describe. The fifth lecture will apply the idea of quantum mechanics to the Big Bang and the origin of the universe. This leads to the assumption that space-time may be limited in scope (dimension), but there is no edge. This may be similar to the surface of the earth, but it has two more dimensions. The sixth lecture will explain how this new boundary condition is explained by the existing knowledge structure: although the laws of physics are symmetrical in time (space), according to the conservation of microscopic particles in chemical theory, any substance (including vacuum state, etc. ), even the "most" stable, essentially "relatively small" changes will occur (see the microscopic particles in the chemical field (charged particles running around the nuclear "planet"). Finally, the seventh lecture will talk about how we try to find a unified theory, and how we can truly unify the quantum mechanics and gravitational physics involved. ) and other disciplines (including the religion of "people" with immortal souls) are integrated into the "ocean" of knowledge. If we do this, we may really understand the forces involved in nature and our position in it. This book is not an ordinary oral history, but an extremely interesting theory and description of one of the greatest thoughts of mankind in the twentieth century. For non-professional readers, this book is undoubtedly an opportunity for them to enjoy the fruits of human civilization and a source of valuable inspiration. Hawking lectures-Black holes, baby universes and others are collections of articles and speeches written by Stephen Hawking and his first wife Jane Wilde, from Hawking1976-1992 * *13. This paper discusses the birth of the initial universe and dimensions caused by virtual space and black (white) holes, and the efforts of scientists to seek a completely unified theory, and puts forward original opinions on issues such as free will, life value and death. After three years of study, which was not a huge workload, he obtained a first-class honorary degree in natural science, and then went to Cambridge University to study cosmology. At that time, there was no cosmology major at Oxford University, so he tried to create it. Although he hoped to do research with Fred Hoyle in Cambridge at that time, his tutor was Dens Scarma. After receiving his doctorate, he became a researcher and later a professor at Gonville and Caius College. 1992 The film of the same name cost 3.5 million pounds. Hawking firmly believes that the basic ideas about the universe and the origin of life can be expressed without mathematics, and the world should be able to understand his profound theory through the audio-visual media such as movies. This book is a popular reading about exploring the nature of time and the frontier of the universe. It is the most important classic of contemporary scientific thinking about the universe, and it has changed the human concept of the universe. As the undisputed authority of cosmology, A Brief History of Time has always attracted readers with its research results and life. The sequel to A Brief History of Time is for readers who know more about Professor Hawking's life and his theory. The book describes Professor Hawking's life course and research work in the form of frank and sincere personal interviews, and shows the real "people" behind the huge theoretical framework. The Chinese version of George's The Secret of the Universe was published in early 2008. This book is written by Stephen Hawking, his daughter Lucy Hawking and his student Christopher jaafar. It is one of the "popular science trilogy" of Stephen Hawking's "children" period. In this book, black holes and many parts briefly describe Hawking's new ideas. This book has received rave reviews at home and abroad. The new documentary "Follow Hawking into the Universe" 10 was broadcast on the American Discovery Channel on April 25th. 2004-stephen william hawking's Hawking Paradox and Conservation of Information On July 2, 2004, at the "17 International Conference on General Relativity and Gravity" held in Dublin, Ireland, Hawking's attitude took a 180 turn, indicating that his original view was wrong and information should be conserved. He announced his latest research results on black holes in the universe: black holes don't "completely devour" everything around them as he and most other physicists thought before. In fact, some information of matter sucked into the depths of a black hole may actually be released at some time: information conservation. The reason is that the black hole is too idealized, and the thermal radiation of the black hole is too idealized. However, Hawking never gave strict proof to support his new ideas. Thorne said that this matter can't be decided by Hawking alone, and he still insists on the view that information is not conserved. Presky said that he couldn't understand Hawking's speech and why he won. At present, this sensitive problem involving the basis of quantum theory is far from being solved. The study of black hole theory has gone beyond the black hole itself. Not only touched the important cornerstone of quantum theory-Mo Zheng, but also opened a new chapter in exploring the nature of time. From 1960s to 1980s, great progress has been made in the study of black holes. At first, people thought that a black hole was a death star, and everything could fall in, but nothing could escape. Hawking proved in 1974 that black holes have temperature and radiation. The discovery of Hawking radiation made black holes and Hawking himself a household name. After 1980s, the focus of black hole research gradually shifted from temperature to information paradox. It has long been known that observers outside a black hole will lose almost all information about the matter that formed the black hole and later fell into it. This is the hairless theorem. The famous "Hawking radiation" theory. The so-called "Mao" means "information". There are only three "hairs" left in the black hole, namely, total mass, total charge and total angular momentum, which can be detected by the outside world. At first, people thought that although external observers could not detect the information of the matter inside the black hole, the information did not disappear from the universe, but was hidden inside the black hole. After the discovery of Hawking radiation, people know that all the substances in black holes will eventually be converted into thermal radiation, and thermal radiation can hardly bring any information. In this way, the information of the matter formed and falling into the black hole will disappear from the universe, and the information will no longer be conserved. Not only does the law of conservation of baryon number and the law of conservation of lepton number no longer hold, but the unitary nature of quantum theory will also be destroyed. Faced with such serious theoretical difficulties, physicists have launched a heated debate. Most theoretical physicists believe in the conservation of information and firmly believe that the cornerstone of quantum theory, that is, it will not be destroyed. In a word, information should be saved. Hawking, Thorne and other relativistic experts believe that information is not necessarily conserved, so it is entirely possible to destroy the singularity. To this end, Hawking and Thorne made a bet with Presky, who firmly believed in the conservation of information. "This theory has been in trouble since its birth: it contradicts the' Law of Conservation of Information' adhered to by many scientists. It was once called the "black hole paradox". Just as scientists in the19th century summed up the law of conservation of energy, many scientists in the 20th century put forward the theory of conservation of information. If this theory is established, the "law of conservation of information" will undoubtedly become the most important law in the scientific community, perhaps surpassing matter.
