According to a report, Stephen Hawking, a well-known physicist and a professor at the University of Cambridge in the United Kingdom, announced that he has given up his pursuit of "Theory of Everything". In the past, he believed that people would soon find one that can at least be described and predicted in principle. The ultimate "universal theory" of everything in the universe, and now he believes that people will never get such a theory; because according to the "G?del's incompleteness theorem" in mathematics, such a theory is impossible at all. According to this text, the incorrect understanding is:. ['The development of any one discipline is inseparable from the support of other disciplines.', "G?del's incompleteness theorem is closer to the truth of things than the theory of everything.", 'The path to truth is not always smooth.', 'Hawking\'s past pursuit of "universal theory" shows people\'s inexhaustible spirit of exploration.']
