The "darkest" secret? Don’t say "darkest" to black holes and galaxies.

  Kant said that there are two things in the world that can shake people’s hearts: one is the high moral standards in our hearts; the other is the starry sky above us.

  In 2020, three scientists won this year’s Nobel Prize in Physics for discovering one of the universe’s strangest phenomena – black holes.

  Where all known laws fail

  An overweight monster will capture anything that enters its "hunting range," not even light can escape. This is a black hole. In many cultural forms, the word black hole has a deeper meaning, but for physicists, black holes have always been the product of the natural death of giant stars after they ran out of energy.

  In the last century, Einstein’s theory of general relativity upended all notions of space and time; Oppenheimer calculated the violent collapse of a massive star. But these were considered purely theoretical conjectures until one man, who first succeeded in finding a solution to reality, was Roger Penrose. He used clever mathematics to show that black holes are a direct prediction of Einstein’s general theory of relativity. Black holes hide incomprehensible strangeness, in which all known laws of nature stop. Published 10 years after Einstein’s death, this paper is regarded as the most important contribution to general relativity.

  There is only one answer: supermassive black holes

  Reinhard Genzel and Andrea Gaetz each led a team of astronomers that successfully mapped the orbits of the brightest stars closest to the center of the Milky Way, and both groups found that there was an invisible, but very heavy object that caused these stars to rotate around at an alarming rate.

  What is this invisible object that weighs as much as 4 million solar masses? According to the attractive force theory, there is only one possible explanation – a supermassive black hole.

  Using the world’s largest telescope to see the center of the Milky Way through giant clouds of interstellar gas and dust, Gentzel and Gates have stretched the limits of technology, perfected new techniques, compensated for distortions caused by Earth’s atmosphere, and created unique instruments that can be used for long-term studies. Their work provides the most convincing evidence yet of a supermassive black hole at the center of the Milky Way, as well as clues to new theoretical insights.

  If anything lasts forever, it’s the unknown.

  Penrose’s work tells us that black holes are a direct result of general relativity, and Genzel and Gaetz have done precise tests of general relativity and its predictions. But in the midst of infinitely large singular attractive forces, the theory no longer applies. Scientists are creating a new theory of quantum attractive forces. This must bring together the two pillars of physics, relativity and quantum mechanics, which will meet inside black holes.

  "It’s not just about their internal structure, but also about how to test our theory of attractive forces in the extreme conditions in the immediate vicinity of black holes," said David Havilland, chairperson of the Nobel physics committee. He believes that it is the discoveries of this year’s winners that have opened up new horizons in the study of compact and supermassive celestial bodies, but these peculiar objects still pose many questions to humanity and inspire people to come up with answers through research.

The Beidou satellite ground-based enhancement system for the Yangtze River trunk line has been officially put into operation, and the accuracy of ship navigation can reach sub-meter level

  Xinhua News Agency, Wuhan, June 1 (Reporter Li Siyuan) According to the Yangtze River Communications Administration of the Ministry of Transport, the Beidou satellite foundation enhancement system project of the Yangtze River trunk line undertaken by the bureau has recently passed the completion and acceptance of the Ministry of Transport, and has been officially put into operation and external service since the 1st. With the help of this system, the navigation accuracy of Yangtze River ships can be improved to sub-meter level.

  The Beidou Satellite Ground Enhancement System Project on the Yangtze River Trunk Line is the Beidou service system with the largest scale, the widest coverage, the most complex network structure and the highest service performance requirements for inland river shipping in China. It started in November 2018. The total investment of the project is 107 million yuan, starting from Yunnan Shuifu in the west and about 2800 kilometers long and 30 kilometers wide in the east to the Yangtze River Estuary. The construction of 106 reference stations, 56 ship automatic identification system broadcasting stations, 154 network channels, 12 new computer rooms, and 2 data centers has realized the full coverage of the Beidou satellite ground enhancement signal on the Yangtze River.

  Shen Jianjun, deputy director of the Yangtze River Communications Administration, said that as an important infrastructure for the information construction of the Yangtze River, the Beidou ground-based enhancement system of the Yangtze River trunk line can provide sub-meter navigation accuracy for ships, and centimeter-level and millimeter-level mapping accuracy services for surveying and surveying. At the same time, by empowering shipping elements in depth, accurate perception, accurate analysis, fine management and careful service, the capabilities of integrated traffic management, maritime safety supervision, and water traffic safety emergency command in the Yangtze River have been comprehensively improved.

  According to the introduction, the Beidou ground-based enhancement service system of the Yangtze River trunk line will also encrypt the existing meteorological station observation network to further enhance the resolution of the Yangtze River meteorological monitoring.

  Shen Jianjun said that in the next step, the Yangtze River Communications Administration will continue to carry out the application research and promotion of Beidou technology in Yangtze River shipping, and gradually realize the synergistic integration with 5G, artificial intelligence and data centers in key shipping elements such as key waters, important hubs, ports and logistics parks.

The movie "Hua Qiangu" released the "Stay with You" version trailer on January 20. It is difficult to choose between good and evil

A few days ago, starring Chen Turin and Li Chengbin, Mao Zijun starred in a special role, Lai Meiyun and Zhang Zining starred, Xu Muchan starred in a special friendship role, Chen Xiaodong and Zhang Li starred in a friendship role, and Jiang Yiming, Wang Xichao, Yang Yi, Xie Chengze, Xie Zichen and other co-starring Oriental fantasy film "Hua Qiangu" exposed the "Stay with You" version of the trailer. As a phenomenal hit IP, the release of many famous scenes in the trailer makes people dream back to the past, restarting the memory of this unparalleled love for the whole people. Hua Qiangu and Baizi paint immortals and demons in a special way, but they can’t love each other, and they can’t choose between good and evil. The film uses Oriental fantasy colors as a light painting style, re-presenting the strong theme of female growth, transformation and relief. After nine years of company, the audience is invited to join the long-term stay. The movie "Flower Qiangu" will be released nationwide on January 20.

Cultivating immortals and changing one’s life is fate or calamity, and it is destined to stay for a long time and rise again


The movie "Hua Qiangu" is adapted from Guoguo’s work "Hua Qiangu", which tells the story of the ancient times, when all the immortals worked together to annihilate the demon gods, and the power of the demon gods was sealed in the three major artifacts. After a thousand years, the evil thoughts of the world gathered, and the seal of the three major artifacts loosened. Once the power of the demon gods gathered, the six realms would be destroyed. The head of Changliu, Bai Zihua, summoned a group of immortal secret merchants with the intention of strengthening the seal. But all the forces of all parties competed for the artifact for their own selfish desires, which caused Bu Yuanding, the leader of the three artifacts, to erupt with deadly poison gas and slaughter the villagers. There was a girl in the village, Hua Qiangu, who had provoked the demons since she was a child, and the flowers and plants withered wherever she dripped She was the only one who survived the village slaughter, and those who didn’t know it thought that she had invited the natural disaster and chased after her. Hua Qiangu went to stay for a long time in her life, trying to change her fate through immortal cultivation. But who knew that Hua Qiangu was not only involved in the battle for the artifact, but also found out that she was the real body of the demon god. Fortunately, Bai Zihua saw that her nature was pure and kind, and taught her personally. However, in order to welcome the arrival of the demon god, the mastermind behind the scenes set up a plan to lure Hua Qiangu to gather the artifact, causing the lives to be ruined… In the face of the murder of her lover, the departure of her loved ones, and the annihilation of Hua Qiangu by pain and resentment, how should she choose this time

In the latest trailer released today (January 4), Hua Qiangu, who has the real body of the demon god, was misunderstood by the world and fled all the way to long stay, but she asked to no longer be displaced in the chaotic times and have a place to live. Bai Zi Hua accepted her as a disciple, and the destined fetters of the two have been intertwined since then. However, creation has tricked people, and Hua Qiangu’s demon god power has gradually been stimulated. In order to protect the common people and rescue his apprentice from being hurt by the demon god’s power, Bai Zi Hua decided to use his thousand-year cultivation base to give it a go. Even so, he still couldn’t get Hua Qiangu out of the fate of being pierced by the soul-destroying nail. The injustice of the world made Hua Qiangu cry unwillingly to fate, and finally woke up the demon god to return to the world. At the end of the trailer, the seriously injured white painting picked up his sword and looked at the powerful demon god with his eyes like torches. How would the ending be?

It is difficult to choose between good and evil, and join hands to go to the nine-year covenant


The identities of Hua Qiangu and Baizi Hua Fairy and Demon were born into opposition, and they couldn’t love each other. Baizi Hua knew that Hua Qiangu was burdened with too many misunderstandings from the world, and from the moment he saved Hua Qiangu, the tribulation of their love began. Love sprouted between the day and night of the master and the disciple’s relationship and thoughts, but the injustice of fate and the hatred of the world eventually pushed the two to the end of their lives. In order to save the master, Hua Qiangu was injured by an arrow, but in exchange for the sword stab of the beloved person, the sword of broken thoughts symbolizing the friendship between the master and the disciple was finally broken. Flower Qiangu, the demon god, stood proudly in the world, opened the revenge mode of divine power, and completely stimulated the conflict and broke with the world. Bai Zi painting in order to end the calamity to risk, even if he for Hua Qiangui block the anger of the world, but the opposition between good and evil they ultimately hard to choose.

As a phenomenon-level hit IP, from the novel to the drama, to the current movie, the fatalistic sadomasochism between the two has been deeply concerned by IP fans, and it can still ignite the enthusiasm of IP fans after nine years. Hua Qiangu’s love is hard to hide being deeply corroded by the pool of unfeeling water, and famous scenes such as Bai Zi’s painting of being punished by immortals to protect her life make people dream back to the past, restarting the memory of the whole people for this unparalleled love. The film’s unswerving and reckless emotional interpretation of the two is exciting. From the slender girl to the peerless demon god, from "I wish, I ask" to "I dare, I can", the film gives a hearty and colorful writing of Hua Qiangu’s fate transformation.

The entire film was filmed in Guangxi, which not only integrated the beautiful natural scenery of Guangxi into the film, but also skillfully integrated world-class cultural heritage Huashan rock paintings and national intangible cultural heritage Nuo opera into the plot at multiple levels and perspectives, enhancing the influence and dissemination of Chinese civilization in a way that "moisturizes things and is silent".
