Rebirth: The No.1 Dandy - Chapter 525
“An important evidence for the existence of dark matter comes from Vera Rubin and Kent Ford’s study of the rotational speed of stars in the Andromeda cloud.
Using high-precision spectral measurement technology, they detected the relationship between the rotation speed and distance of peripheral stars far away from the galactic nucleus.
According to Newton’s law of universal gravitation, if the mass of the galaxy is mainly concentrated on the visible stars in the galactic core, the velocity of the stars outside the galaxy will decrease with distance.
However, the observation results show that the velocity of stars outside the galaxy is constant in a considerable range, which means that there may be a large amount of invisible matter in the galaxy, which is not only distributed in the galaxy core, but also its mass is much greater than the total mass of luminous stars.
Combined with the potential force theorem, the distribution of matter in galaxies can be calculated from the dispersion velocity distribution of visible objects in galaxies.
This method is also suitable for measuring the material distribution of elliptical galaxies and globular clusters.
The results show that except for a few, the material distribution of most galaxies and clusters is inconsistent with the observed distribution of visible material, and the mass of visible material accounts for only a small part of the total mass of galaxies and clusters.

The students in the physics department listened attentively one by one, but Xiao SA was indifferent. He knew nothing about Astrophysics and couldn’t understand it!
However, he sat in the first row, watching Danlu confidently face thousands of students and professors of Tsinghua University, calmly, humbly, calmly, and greatly proud in his heart!
Especially Danlu has always been so pure and refined, with a smile and a smile, and his every move is so beautiful. He simply doesn’t bother to listen and keeps taking pictures with a camera.
He also specially arranged personnel to record the whole process, leaving a good memory for Danlu.
It was perfect. Danlu ended the lecture for nearly three hours in thunderous applause and cheers.
The school arranged a banquet and invited several of Danlu’s classmates to accompany him. One person Xiao SA knew: Liu Qi. This guy secretly pursued Danlu in college.
After graduating from Tsinghua University, Liu Qi was admitted as a graduate student of Tsinghua University. Now he is a lecturer at Tsinghua University.
Liu Qi has a leather collar in his suit today. His hair has been blown intentionally. He can learn from it. He is very scholarly with a pair of gold wire glasses.
At first, Danlu and her classmates talked happily while eating and drinking, nothing more than talking about things after graduation. What do you do? Are you looking for friends? Are you married and have children? Of course, I also recall some things I remember deeply in my college life, both wonderful and angry; There are happy and sad
Wine is red wine. I drink a little more unconsciously.
Liu Qi got excited, poured out two glasses of red wine, went to Danlu and said, “younger martial sister, you are now a famous physicist at home and abroad. Your great discovery of dark matter has been recorded in history, and has been quoted and published in a large number of authoritative academic journals in the world. Great! Elder martial brother, I’m ashamed! Come on, I’ll give you a full glass today!”
Danlu took up her glass, touched it with him and took a sip.
Liu Qi looked up and gulped the full glass of red wine, lit the bottom of the glass and said, “younger martial sister, don’t you give face for a glass of wine?”
Danlu looked at Xiao SA with a helping eye.
Xiao SA smiled, picked up Danlu’s glass and said, “I’ll come.”
Unexpectedly, Liu Qi went crazy with wine. His face sank and said to Xiao SA, “what are you? Can you drink for my younger martial sister? Do you know where this is? It’s a palace of science! I know you. Don’t you just have two bad money? You’re full of copper smell! Dare to mix with us? Get out!”
Xiao spilled a glass of red wine and spilled it out. Liu Qi spilled it all over his face and said, “give your face, don’t be ashamed!”
Liu Qi rushed up to beat Xiao SA. Xiao SA had already kicked Liu Qi out and kicked Liu Qi to the ground. Other students hurried forward to pull them apart, and the banquet broke up unhappily.
This was originally a small matter. Xiao SA didn’t worry about it. He didn’t care when he went back. Unexpectedly, in the evening, Danlu’s classmates called and quietly told Danlu that Liu Qi lost face today and was ready to retaliate against Xiao SA!
Moreover, the classmate also revealed a message to Danlu. Liu Qi’s own family is ordinary, but his sister married a powerful man, so his tone is also high. She threatened to kill Xiao SA and let Xiao SA go around in the capital. It’s hard to say whether she has life to get out of the capital!
Danlu was worried, but Xiao SA didn’t care much.
But trouble is really coming!
Three projects under construction of dream chasing group: the construction project of mobile branch in Changping County, the construction project of computer branch in Fengtai District and the construction project of CNC branch in Chaoyang District were suddenly inspected, and without exception, they received a notice ordering shutdown and rectification the next day.
There are a variety of reasons, such as what civil air defense projects are not in place, non-standard fire access and so on
Ji Zhuo, the general manager of the company, hurried to find the leaders of the district governments for coordination. Unexpectedly, the leaders of the district governments did not know. The inspection team was sent down by the city, and the notice ordering the shutdown and rectification was also issued by the relevant departments in Beijing.
Ji Zhuo hurried to find the person in charge of relevant departments in Beijing to coordinate. Finally, he vaguely heard a rumor that dream chasing company offended the wrong person!
Jizhuo hurried to find Xiao SA.
Xiao SA was happily inspecting the 20 Jiajiale supermarkets that the third girl Wu Yang had just opened in Beijing.
He looked at it from family to family and was generally satisfied.
First, the site selection is good. Without exception, all supermarkets are selected at the intersection with dense traffic, and there are large parking lots, so customers flow and business is busy. This is the most important thing. It’s only reliable to make money!
Second, the zoning layout is more reasonable, which is in line with customers’ consumption habits and consumption psychology.
Third, the decoration style is unified, concise and lively, so that customers feel warm and comfortable.
Fourth, the goods on the shelves are relatively complete and sufficient, and there are many opportunities for customers to choose.
Fifthly, the employees have been trained to work, the service attitude is very good, and they are very responsible.
Sixth, the cleaning work is done well, not dirty or dirty.
Seventh, all aspects of management are relatively standardized and orderly, busy but not chaotic.
……
However, Xiao Sa also put forward many criticisms and suggestions. In his previous life, he knew too much about supermarkets, so it was easy to find problems. He was inevitably picky, which made Wu Yang, Li Tian and others unable to hang on their faces.
However, Xiao sa soon found his own problems. When summing up, he praised Wu Yang, Li Tian, Zhang Qing and others without stinginess. Li Tian and Zhang Qing were relieved. Wu Yang was not happy!
It was at this time that Xiao SA received a report call from Jizhuo.
