Sign in, people are on an isolated island, and they just built a luxury villa by themselves

Chapter 1408 Shocked, analyzed, learned mathematics, physics and chemistry well

Soon, another spaceship flew from a distance, picked up the supply box and sent it to Chaos Star.

Xiao Yi naturally saw the other party's movements, and shook his head with a smile. He understood Chaos Star's movements very well.

If an alien gives you something, as long as it is a normal person, it will definitely be extremely cautious!

With Chaos Star's scientific and technological strength, the conditions on their spaceship are definitely not enough to judge the safety of the items Xiao Yi gave, and it became inevitable to send them back.

After making an agreement with Chaos Star, Xiao Yi came to the island monument again and looked at the information in the public channel!

"Recently, I feel that the spaceship of Chaos Star seems to be a little active!"

"how do I say this?"

"I often see spaceships flying around in front of me."

"It is estimated that the boss has frequent contacts with Chaos Star, maybe he is delivering food or something!"

"This is a real hammer, the boss must have gotten so much food from Chaos Star!"

"Can we also contact that Chaos Star?"

"Brother, I advise you to let go of such a dangerous idea. If you have upgraded to a miniature spaceship, you can still try it. If not, I advise you not to be impulsive!"

"Yes, only strength is the basis for contacting the natives!"

"In addition to strength, there is also whether the communication between each other is smooth. If you don't understand the language of Chaos Star and contact them rashly, there is a high possibility of misunderstanding."

"That's right, you go up in an escape pod, and you have no way to communicate with each other, so you will probably be directly destroyed."

"Hey, being weak is the original sin!"

During everyone's discussion, the Chaos Star Cargo Spaceship had transported the food and water that Xiao Yi had given them back to the Chaos Star.

The material box was quickly sent to the research institute on Chaos Star.

"Is this what the people on Earth gave us?" Wang Yang, who was wearing a thick protective suit, looked at the pure water from potatoes and corn in front of him, and couldn't believe it.

"That's it. I've got people to start testing these things here, and the results should come out soon!" The deputy on the side replied in a deep voice.

Wang Yang nodded. At this moment, a sudden exclamation came from the laboratory: "How is this possible?"

Wang Yang and the two walked towards the laboratory, where the staff in the laboratory were discussing.

"These things contain a substance that we have never found before!"

"Yes, the activity of this substance is so high!"

"Based on the results of the current tests, these foods and water should be able to improve our physical condition!"

Hearing their discussion, Wang Yang asked, "Did you find anything?"

Seeing the star master coming, the person in charge of the laboratory joined in and said, "Star master, we have discovered a substance that we have never discovered from the food and water provided to us by the people on earth."

Wang Yang frowned and asked, "Is this substance poisonous?"

"There is no toxicity found so far, but we don't know if our body can withstand the activity of this substance. If it can, we can improve our physical fitness by eating this kind of food!" the person in charge replied.Wang Yang nodded: "Let's conduct experiments on mice first!"

"Yes!" The person in charge replied.

The lab is busy again.

The deputy next to Wang Yang asked, "Star Lord, what do you think this earthling is going to do?"

Wang Yang shook his head: "I don't know, but if he really wants to destroy us, it shouldn't be so troublesome!"

"Well, is it really just a show of favor?" The deputy said uncertainly.

"It should be. The other party didn't even get our supplies, so he gave us some first. It should be just a gesture of goodwill!" Wang Yang thought for a while and said.

"Maybe, let's wait for the test results to come out!" The deputy on the side didn't make any comments.

At this time, Xiao Yi watched the public channel from time to time when someone responded that the spacesuit in the cabin was opened, and he knew that some changes must be taking place in this galaxy.

Perhaps the shortening of the comet's revolution period is also affected by this change.

"Did you pay attention to whether your orbit has changed?" Xiao Yi switched to the private chat channel, found Zhu Wu and asked.

"There are changes, but it doesn't feel like a big deal!" Zhu Wu replied.

"If the trajectory does not change much, it can only mean that the comet's speed has increased!" Xiao Yi frowned and analyzed, "According to the formula of centripetal force F=mV^2/R, the comet's mass has not changed much and its trajectory has not changed much. , the speed increases, indicating that the centripetal force has increased.”

"Island Master, I feel that here, we can't use this simple physics theory to calculate?" Zhu Wu said uncertainly.

"It's true that it can't be so simple and rude, but we only made a general analysis, and we are not prepared to find out the exact reason!" Xiao Yi replied.

Zhu Wu nodded slightly, and then asked again: "What if all the physics we learned before are not applicable here?"

"Maybe, but now we can only use what we know to infer!" Xiao Yi said helplessly, "Let's assume for now that the physics we apply is correct!"

"Well, according to our current knowledge, we can indeed deduce that the centripetal force has increased!" Zhu Wu said.

Xiao Yi continued his analysis: "The centripetal force of the comet's revolution around the star is provided by universal gravity, and the formula of universal gravity is F=GMm/R^2. The gravitational constant G remains unchanged, and the comet mass m and the distance R between the two are roughly different. Change, in order to increase the gravitational force, the star’s mass M can only increase!”

"The owner of the island is awesome, I think I failed in physics back then!" Zhu Wu said with emotion.

Xiao Yi replied with a smile: "There is an old saying in my home planet, if you learn mathematics, physics and chemistry well, you will not be afraid to travel all over the world!"

"This old saying really makes sense!" Zhu Wu responded.

Xiao Yi nodded slightly, and then continued: "According to the current calculations, the mass of the stars in our solar system has increased, what will cause the mass of the stars to increase?"

"Could it be that the stars in this galaxy have begun to transform into red giants?" Zhu Wu suddenly thought of some popular science articles he had read on his home star.

After the nuclear fusion of the star is completed, the core no longer produces energy, causing the surface to expand and the center to collapse. In the process of expansion, all celestial bodies within the diameter of its expanded volume are eaten!
Hearing Zhu Wu's words, Xiao Yi nodded slightly, and said, "It's very possible, but if that's the case, Chaos Planet should be aware of it. I'll ask about the situation on Chaos Planet!"

"Yes, maybe Chaos Star knows more than us!" Zhu Wu said excitedly, and then he was a little worried, "If our deduction is correct, will this comet also be swallowed by this star?" ?”
