    "So that's it" The old man looked like he suddenly understood, but immediately changed his expression and asked, "Then why can't you see the stars on a cloudy day when the sun is not strong?" Yunyang was speechless: "Everyone  It's cloudy, and the sun's rays are so heavily blocked, not to mention the weak starlight. " "Yes I'm really confused." The old man patted his head, "What did Mr. Five just talk about in the starry sky and the universe?  I have never heard of these strange and wonderful things before. I wonder if Mr. Wu can tell me more? " "This old man has a pretty good attitude, so let's not argue with him. He is also older when it comes to becoming a disciple.  Don't humiliate him, just let this matter go." Yun Yang thought in his mind.  Yunyang does not have an aggressive personality. He has always believed in treating others with kindness and mercy. The anger he had before has long since faded away, but Yunyang still has things to do. He was interested and talked a little more here.  , but now I don¡¯t want to delay it any longer.  "If you are interested, old gentleman we can naturally communicate with each other in the future. However, I do have some things at this time that I need Songhe's help with. Why don't we talk about it another day?" Yunyang said.  The old man's face was full of disappointment: "That's it, Mr. Five can do whatever he wants. But I have one last question to ask. Mr. Five just said that the Sun Star is more than 300,000 times heavier than the Zu Star. I wonder how it was measured? That's it.  To measure the weight of the Sun Star, I wonder if it is possible to measure the Ancestral Star and measure the weight of Chang Geng? " "This" Yun Yang hesitated.  Yunyang naturally knows these data and has specific measurement methods, but the simplest way is to introduce the concept of Newtonian mechanics. For the world at this moment, Newtonian mechanics is too advanced.  Yunyang hesitated, but the old man only thought that Yunyang was trying to evade, so he couldn't help but gritted his teeth, and suddenly bent down and bowed to Yunyang: "I had a lot of offense to Mr. Wu before. Although Mr. Wu didn't say much, the old man did.  I know that Old Man is probably wrong when it comes to the movement of stars. Old Man said before that if he loses the debate, he will become Master Wu. Now he will keep his promise and ask Mr. Wu to accept this incompetent disciple. " "  Yang was taken aback.  It is really not a wonderful feeling to have an old man salute to you.  Yunyang hurriedly helped the old man, saying at the same time: "This can't be done, this can't be doneOld sir, get up quickly."  Old man, I hope Mr. Wu will not hide his secrets and can give me some advice" But the old man insisted and refused to get up.  Yunyang couldn't help but feel helpless: "What did the old gentleman say? How can I give advice? It's absolutely impossible to ask me to be my teacher How about this, let's make friends and stay friends forever. It's about astronomy."  As for things, we can communicate with each other, and Yunyang will definitely not hide anything. As for giving advice, he would never take it seriously. "The old man finally straightened up, and seeing Yunyang's sincerity, he said with emotion: "I used to be old.  I listened to people's words and thought that Mr. Wu was a dandy with no knowledge and skills and only knew how to destroy. Today, I saw Mr. Wu. He is rich in knowledge and courteous to others Only today did I realize that compared to Mr. Wu, there are many people who are not as good as him.  " Yunyang smiled bitterly and thought to himself: "This is probably the first step for me to change my image" There was a buzz of discussion below: "Although Professor Chen has a fiery personality, he is a good person.  He is really good at what he says, and he corrects his mistakes when he sees them He doesn't rely on his elders just because he is old. " "Mr. Wu is also good He knows so many things, and he can impress even Professor Chen in astronomy.  I used to think that Mr. Wu was an ignorant and ignorant playboy, but when I met him today, I realized that you should not just listen to what others say" "Songhe, Songhe, you and Mr. Wu go to Chang Geng together. Mr. Wu also said  "What did you learn?" Songhe, who had been unanimously despised before, now became the focus of everyone, and Songhe became complacent: "Uncle Yun has talked about a lot of things Do you know that Suixing and Zhenxing are actually  They are all a big ball of gas, and besides the Zhenxing, there are actually several stars that we cannot see orbiting the sun, and they are bigger than the Ancestral Star" There was a discussion below and Yunyang didn't pay attention.  But this old man has obviously become obsessed with Yunyang.  The old man was so polite, Yunyang was too embarrassed to leave, so he could only reply with a wry smile: "What did the old man say? The old man specializes in astronomy, and Yunyang also admires his accomplishments here" "I don't know what Mr. Wu can do.  Is there a way to measure the distance between the stars and the ancestral star?" the old man asked.  "This" Yun Yang hesitated for a moment, "It's possible, but it's very troublesome. With our current conditions, it's probably impossible but measuring the sun, stars, and length of time?, The distance between Yinghuo, Suixing, Zhenxing and Zuxing can be determined, but it is also very difficult" Determining the distance between the other planets in the solar system and the earth can be done by introducing Kepler's law  , but Kepler's law is obviously too advanced for the world at this moment, so Yun Yang was embarrassed. The old man's expression dimmed again, and he murmured: "Is it difficult?  Then Then, I wonder if Mr. Wu can determine the size of the ancestral star?  " "Huh?  !  Yunyang looked at the old man in surprise, "You haven't determined the size of the Ancestral Star yet?"  This is a very simple thing.  "    "Simple?  The old man was immediately pleasantly surprised: "Simple is good, simple is good. To be honest, I and my colleagues have been thinking hard for a long time on how to measure the size of the ancestral star, but they have never been able to find a way Since Mr. Wu said  I have a method, but I wonder if I can teach it to the old man?  After the measurement is made, it will be announced to the entire Qiankun Martial Arts Academy in the future, and it will definitely be marked on the front as measured by the fifth teacher of the academy" "Measurement of the size of the ancestral star?  !  Mr. Wu has a way to determine the size of the ancestral star?  This, this this will definitely be a grand event in our Shenghua City" "Someone has proposed before that the masters of the Transcendent Realm should leave Shenghua City, walk around the ancestral star, and then calculate the radius from the circumference, but this is too inappropriate.  Accurately, not only the direction cannot be determined, but we don¡¯t even know whether the circle we walked is the longest one on the ancestral star" In terms of this sentence, it means that it is impossible to determine whether the circle we walked is the equator of the earth.  Obviously, only the latitude of the equator can be used to calculate the radius of the earth, and other latitudes cannot be calculated. People in this era probably did not have the concept of the north and south poles, and they could not calculate the radius of the earth by measuring the length of the longitude. "This.  The method is simple" Yunyang said helplessly, "But I can't do it myself. This requires manpower Also, the time is not right now. I wonder if the old gentleman can wait a little longer" "Manpower  ?  The old man suddenly straightened his back: "Mr. Wu really has a way?"  Don't worry about Mr. Five's manpower. The students in this classroom can all be driven by Mr. Five. If it's not enough, Mr. Five can ask for it, and the college will definitely respond to requests.  " Someone in the classroom below suddenly shouted: "Mr. Wu, please take us to measure the size of the ancestral star!  " "Please ask Mr. Wu to take us to determine the size of the ancestral star!  ¡± The sound suddenly became loud. Yunyang turned around and saw that Songhe was shouting the loudest. ¡°I¡¯m kidding, this is to determine the size of the ancestral star! Although this matter has no practical significance, it has symbolic significance.  But it is extremely important. Probably everyone except Yunyang knows how serious the dispute between Shenghua City and the other eleven main cities is. To put it simply, it is best to measure the weight of the earth.  Describing the earth in various accurate digital ways has an unparalleled effect in strengthening the faith of the people of Shenghua City. At the same time, it also plays an extremely important role in combating the remaining eleven cities - because of the gang of gods.  Sticks are always talking about it, and they always try to infiltrate the sacred concept of the ancestral star into Shenghua City. The Foreign Intelligence Service catches many spies every year, and every year there are always people who are tainted by this kind of thinking To put it bluntly, this  The significance of this matter is to reveal a truth to everyone, that is: as long as we continue to explore and continue to become stronger, then anything can be done and any mystery can be explored clearly, and this is undoubtedly an encouragement to believe in God wholeheartedly.  , and the idea of ??letting the gods arrange everything is seriously conflicting. Probably only Yunyang himself didn't know this. Naturally, the old man figured this out very early. In fact, deep down in his heart, he  He is also extremely eager to see that what Yunyang said about the earth and Chang Geng being both revolving around the sun is true, because if this can be confirmed, the foundation of the doctrine of Wanhua God will be shaken, but everything he has studied will be shaken.  Everything he saw and came into contact with told him that the sun, moon and stars were all revolving around the earth, so he had to stick to this theory. Of course, there was no way to decide whether the earth revolved around the sun or the sun revolved around the earth.  Use intuitive evidence to prove it, but measuring the size of the ancestral star can be shown with clear processes and reasoning. It¡¯s no wonder that the old man was so excited. Yunyang had to make concessions:  "Okay, okay, uh, I promise everyone that after I finish what I'm doing, I will lead you to determine the size of the ancestral star Now, I'm really in a hurry and I really have to leave first. I'm sorry, old man.  Yunyang will visit another daySonghe, come out quickly!  " Songhe hurriedly ran out. Yunyang pulled Songhe and turned away. Behind him, the old man kept shouting: "FiveSir, please don¡¯t forget If you don¡¯t come for three days, I will go to the back mountain to look for you"
