The foreign trade department of the company discussed the photos of the central black hole of the Milky Way Galaxy released for the first time

Early this morning, the staff of the flange Foreign Trade Department of Shanxi Haokun flanges Group Co., Ltd. were excited to discuss. The general manager in charge of flange foreign trade looked surprised after entering the door. Because he accompanied the customer to inspect a batch of stainless steel flanges by remote video in the factory yesterday, he was busy and didn't have time to watch the news and hot search. Our flange salesperson and experience explained: "today, we are more happy than we received a large flange order. The general manager in charge of flange foreign trade looks curious." Last night, the first photo of the black hole Sagittarius A * (Sgr A *) in the center of the Milky Way galaxy was unveiled at the Shanghai Observatory of the Chinese Academy of Sciences. For the first time, photos of the black hole in the center of the Milky way were released. Is it worth celebrating more than we take a big flange order? This is exciting news. The rest of the world's five cities have released this photo at the same time as China. It has been 50 years since British physicist Hawking put forward the idea of black hole, which was first put forward by Einstein's general theory of relativity. Black hole is a very dense celestial body with strong gravity. Even light cannot escape in a certain area around it. The maximum boundary of this area is called "event horizon". This is a demonstration of black holes. This is a major breakthrough in our astronomical system. It is more difficult to "shoot" than the first black hole photo of mankind. But we did. "China's rapid development has attracted the attention of the world. Our astronomy and aerospace fields have been making breakthroughs, which also means that our flange may be sold to a wider range in the future. We also hope that our flange can have more practical significance. We will follow the development of our country and constantly improve the quality and technology of our flange.
