Chapter 1412 shock, analysis, learn mathematics, physics and chemistry
Soon, another spaceship flew from a distance, picked up the supply box, and sent it to the Chaos Star.
Xiao Yi naturally saw the other party's movements, smiled and shook his head. He understood Chaos Star's movements very well.
If an alien gives you something, a normal person would definitely be extremely cautious!
With the technological strength of Chaos Star, the conditions on their spaceship are definitely not enough to judge the safety of the items given by Xiao Yi, so sending them back becomes inevitable.
After making an agreement with Chaos Star, Xiao Yi came to the island monument again and looked at the information in the public channel!
"It feels like Chaos Star's spaceship has been moving a lot lately!"
"How do you say this?"
"I often see spaceships flying in front of me."
"Then it's probably because the boss has frequent contacts with Chaos Star, maybe he's transporting food or something like that!"
"Isn't this true? The boss must have gotten so much food from the Chaos Star!"
"Can we also make contact with the Chaos Star?"
"Brother, I advise you to put down such dangerous ideas. If you have upgraded to a micro spaceship, you can still try it. If not, I advise you not to be impulsive!"
"Yes, only strength is the basis for contacting the indigenous people!"
"In addition to strength, there is also the smoothness of communication between each other. If you don't understand the language of Chaos Star and contact them rashly, misunderstandings are likely to occur."
"That's right, if you go up in an escape cabin and have no way to communicate with each other, you will probably be destroyed directly."
"Oh, being weak is the original sin!"
During everyone's discussion, the Chaos Star cargo spacecraft had already transported the food and water given to them by Xiao Yi back to the Chaos Star.
The supply box was quickly delivered to the research institute on Chaos Planet.
"Is this what the people on earth gave us?" Wang Yang, who was wearing thick protective clothing, looked at the pure potato and corn water in front of him and couldn't believe it.
"That's it. I've already had people start testing these things, and the results should be out soon!" the deputy on the side replied in a deep voice.
Wang Yang nodded. At this moment, an exclamation suddenly came from the laboratory: "How is this possible?"
Wang Yang and the two walked to the laboratory, where the staff in the laboratory were discussing.
"These things actually contain a substance we have never discovered before!"
"Yes, this substance is so active!"
"Based on the current test results, it is speculated that these foods and water should be able to improve our physical condition!"
After hearing their discussion, Wang Yang asked: "Did you find anything like this?"
Seeing the Star Lord coming, the person in charge of the laboratory came over and said: "Star Lord, 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 currently no toxicity found, but we don't know whether 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 responded.
The laboratory became busy again.
The deputy next to Wang Yang asked: "Star Master, 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, he shouldn't have to go to such trouble!"
"Well, is it really just a show of goodwill?" the deputy said uncertainly.
"That should be the case. The other party didn't even get our supplies, so they gave us some first. It was probably just a sign of goodwill!" Wang Yang thought for a while and said.
"Maybe, let's wait until the test results come out!" The deputy on the side did not make any comments.
At this time, Xiao Yi watched the public channel where people responded from time to time by taking out the spacesuits inside the cabin. He knew that certain changes were definitely taking place in this galaxy.
Perhaps the shortening of the comet's orbital period is also affected by this change.
"Have you noticed any changes in your orbital trajectory?" Xiao Yi switched to the private chat channel and found Zhu Wu and asked.
"There have been changes, but they don't feel very big!" 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 like we can't use this simple physics theory to calculate here, right?" Zhu Wu said uncertainly.
"It really can't be so simple and crude, but we are only making a rough analysis and are not prepared to find the precise reason!" Xiao Yi replied.
Zhu Wu nodded slightly, and then asked again: "What if all the physics we learned before are no longer applicable here?"
"Maybe, but now we can only use the knowledge we know to make inferences!" Xiao Yi said helplessly, "Let's assume for the moment that the physics we apply is correct!"
"Well, based on our current knowledge, we can indeed deduce that the centripetal force has improved!" 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, to increase the gravitational force, the only way is for the star mass m to become larger!"
"The island owner is awesome, I think I failed physics back then!" Zhu Wu said with emotion.
Xiao Yi smiled and replied: "There is an old saying from my home planet, if you learn mathematics, physics and chemistry well, you will not be afraid of traveling around the world!"
"There is some truth to this old saying!" Zhu Wu responded.
Xiao Yi nodded slightly, and then continued: "According to current calculations, the mass of stars in our galaxy has become larger. What causes the stars to become larger in mass?"
"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 planet.
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. During the expansion process, it eats all celestial bodies within the diameter of its expanded volume!
Hearing Zhu Wu's words, Xiao Yi nodded slightly and said: "This is very possible, but if this is the case, Chaos Planet should be aware of it. I will ask about the situation on Chaos Star!"
"Yes, maybe Chaos Star knows more than us!" Zhu Wu said excitedly, and then became a little worried, "If our inference is correct, then will this comet also be swallowed by this star?
