Since Hua Feng handed over the magnet stone to Lin Chong, they were separated, Zhang Sanfeng and Yichenzi returned to Wudang Mountain.

Dan Qiusheng returned to Longhu Mountain to visit Zhang Tianshi and presided over the daily work of the Huaxia Cultivators Association and the One Qi Dao Alliance.

The other people from the Flying Dragon Battalion came to pick them up, along with Li Long, Wang Yue, and Shuang Ning, and returned to Lushan to carry out a new mission. And Bai Feng still formed a three-person team with Yun Meng and Hua Feng to continue to stand by in Nanjing.

It's been three days since the last separation. At this moment, Jinling City is calm as usual, Hua Feng is practicing the exercises he has learned in addition to accompanying his parents every day, and his life is also full and comfortable.

At the Chinese Academy of Sciences, astrophysicists are sorting out the information on Hawking more than a hundred years ago:

Stephen William Hawking is one of the world's most internationally renowned greats of this century, a professor in the Department of Mathematics and Theoretical Physics at the University of Cambridge, and one of the foremost general relativity and cosmologists of our time. He was awarded the Lucas Chair in Mathematics at the University of Cambridge, the most honoured chair in the history of the natural sciences after Newton and Dirac.

In the 70s of the 20th century, together with Penrose, he proved the famous singularity theorem, for which they were jointly awarded the 1988 Wolf Prize in Physics. As a result, he has been hailed as the world's most famous scientific thinker and the most prominent theoretical physicist after Einstein. With a thin "A Brief History of Time", it has conquered 30 million readers around the world. The black hole theory has perfectly unified quantum theory and thermodynamics in the "Hawking radiation", and the quantum cosmology of the borderless vision he proposed in the 80s of the 20th century has solved the "first push" problem that has plagued the scientific community for hundreds of years.

Stephen William Hawking's work laid the groundwork for today's understanding of black holes and the origin of the universe, but he also notes that his performances in the animated film "The Simpsons" and the sci-fi series "Star Trek: The Next Generation" are just as impressive.

Stephen Hawking emphasized in "The Great Design" that the universe does not need a creator or "God", and began with "philosophy is dead", which means that human beings will be detached from ignorant self-enslavement, and denies that pure philosophy and religion can truly explain nature, which also shows that the major religions are only systems for the ancient spiritual world to explore the unknown and pursue immortal liberation, rather than objective truth. With the progress of the times, human civilization should also catch up and not be left behind, which is why generations of people of insight have pursued the meaning of existence, life and the universe. Solving these propositions should have been the task of philosophers, but it is a pity that the high development of science has made it impossible for philosophy to keep up. This is what Hawking meant when he said in the opening chapter of "The Great Design" that "philosophy is dead".

Hawking wanted to unravel the mysteries of the birth of the universe, and in the 1970s, Hawking applied quantum mechanics to explain the phenomenon of black holes, and in the next 30 years, it has become more difficult to explain the entire universe with quantum mechanics. Stephen Hawking wanted to find a theory that could perfectly explain the entire universe to explain the universe that was born 13.7 billion years ago until now, but after many years, even if he was infinitely close, he still did not come to a conclusion. According to his theory of quantum mechanics, the universe was born from the Big Bang, the product of the explosion of a compressed infinitesimally small matter with great gravity (which can also be understood as infinite density). The theoretical category of quantum mechanics can't explain how this process works? Why is this so? Hawking said, "There must be a theory that can describe small-scale gravity."

The latest scientific breakthrough is Hawking's colleague, Michael Green of Queen Mary College of London. Green's superstring theory, referred to as "string theory", which points out that all particles and natural forces are actually tiny string-like objects in oscillation, solves the problem of gravity that Hawking has been trying to solve, and this theory must be based on the fact that the universe must have 9, 10, or even greater than 11 dimensions, and the three-dimensional world in which humans live may only be one of the membranes of the real universe......

Numerous scientists from all over the world are conducting experiments in space and on Earth to prove string theory, as well as experimentally proving to support Hawking's black hole theory and quantum theory. On January 24, 2014, Professor Stephen Hawking, a famous British scientist, once again shocked the physics community with his theory related to black holes, admitting in a paper published a few days ago that "black holes do not exist", but "gray holes" do exist. In the paper, "Information Preservation and Weather Forecasting For Black Holes," Hawking argues that "black holes do not exist" because they cannot find their boundaries, in order to solve the "firewall" problem by assuming that "black holes do not exist" in the new theory, which does not really do not exist. The boundary of a black hole is also known as the "event horizon", and the classical black hole theory holds that matter and radiation outside the black hole can enter the black hole through the event horizon, and no matter or radiation inside the black hole can pass through the event horizon.

Stephen Hawking's latest "gray hole" theory suggests that matter and energy are re-released into the universe after being trapped in a black hole for a period of time. In his paper, he admits that his initial understanding of the horizon was flawed, and that light can actually pass through the horizon. As light escapes the core of a black hole, its motion is like a person running on a treadmill, slowly contracting by radiating outward. "Classical black hole theory holds that no matter or radiation can escape a black hole, while quantum mechanical theory suggests that energy and information can escape from a black hole. Hawking also points out that an explanation for this escape process requires a theory that successfully blends gravity with other fundamental forces. No one in physics has tried to explain this process for nearly a hundred years.

Some scientists agree with Hawking's "gray hole" theory, while others are skeptical. Joseph Polchinski, a theoretical physicist at the Kavli Institute for Theoretical Physics in the United States, pointed out that according to Einstein's theory of gravity, the boundaries of black holes exist, but they are not distinct from the rest of the universe. In fact, as early as 2004, Hawking made a similar statement. On July 21 of that year, Stephen Hawking pointed out at the 17th International Congress on General Relativity and Gravitation that black holes were not "completely devoured," as he and most other physicists had previously believed, and that in fact some of the information about the matter that had been sucked into the depths of the black hole might be released at some point.

And none of this has been made substantially until today, about space, black holes, gray holes. There is still a lot of work to be done for people today.
