Chapter 148 Mysterious Source of Gravity

This alien creation is very easy to use. Just input different parameters and different pictures will pop up. Interesting, very interesting... Yu Yifeng kept experimenting, just like playing with a new toy.

All kinds of pictures are full of alternative astronomical beauty, because the object of observation is gravitational waves, which look like ripple-like radiation sources.

In fact, humans are in such superposition states of gravitational waves. They are invisible and intangible, but they really exist. Gravity is the weakest of the four fundamental forces. The gravitational force between two protons is only 1/(1.235*10^36) of the electromagnetic force between them, which is almost negligible.

But on a macroscopic scale, gravity becomes the only force that controls the movement of celestial bodies.

The strongest gravity is much stronger than the strong interaction. Even light can't break free, and even neutron stars will be torn apart!

It has to be said that this is a miracle that accumulates little by little, from the smallest to the largest, from the weakest to the strongest. Gravity can be said to be a typical struggle for losers to reach the peak of life.

Even someone like Xu Yunjin, who doesn't understand science, was immersed in the beautiful picture.

Yu Yifeng discovered that this telescope can even clearly "see" things hundreds of millions of light years away, and can also roughly estimate the mass, size and distance of the object from the picture.

However, because the gravitational waves are so weak, this machine still has its limits. The farther the distance, the higher the computer's computing power and the quality of the observed object.

After a simple test, only large mass sources such as stars, neutron stars, and black holes can be observed for things hundreds of millions of light years away, and other tiny planets are powerless.

The closer the distance, the higher the measurement accuracy. Even small meteorites and comets can be "seen" within one light year!

However, this telescope has a big flaw. Compared with a radio telescope, it can't see the specific picture clearly, and can only use corrugated dots instead. In other words, it can only observe the position and movement of the target.

Well... no matter what, it is countless times clearer than human telescopes. At least human telescopes cannot "see" anything blocked by planets...

"The spaceship of the Green Light Civilization is very large, the mass should be not small, and it is relatively close to us... it should be clearly observed." Professor Thomson listed a series of data on the screen and said carefully.

Yu Yifeng nodded: "Then let's try it, what is the mass of Sedna?"

Now we should get down to business. They spent so much effort just to monitor the Green Light Civilization spaceship.

This is the most important thing. If we can't see the other party's spaceship, people will have no sense of security.

"The mass level of Sedna should be around 10^20 kilograms. As for the spacecraft of the Green Light Civilization, the mass cannot be accurately estimated because the specific materials and related structures are unknown..."

Professor Thomson pondered for a moment and wrote a line of data on the paper: "Its diameter is 150 kilometers. It is assumed that its overall density is slightly lighter than water, and its mass level is about 10^14-10^16 kilograms. Anyway, it should not be as light as Noah."

The observation object of this telescope must start at least tens of billions of tons, that is, 10^11 kilograms. A spacecraft like Noah, which is huge in size and has a mass of only a few million tons, is too small to be observed.

Yu Yifeng entered the relevant parameters according to Professor Thomson's statement and hit the Enter key. There were as many as thousands of celestial bodies that appeared this time!

This includes a pile of meteorites after the explosion of the earth and the tearing of the moon... Well, the solar system does have so many small celestial bodies with a mass distribution between 10^14-10^20 kilograms.

It took everyone a minute to easily find the gravitational source represented by Sedna, and then...

It was gone! There was no spaceship!

"What happened?"

In just a moment, Yu Yifeng felt a chill on his back. He immediately thought of something not so good. Did the spaceship hide on purpose? Or...has it left Sedna?

Failed! The gravitational wave telescope they had high hopes for actually failed! Xu Yunjin and others also clenched their fists tightly, with cold sweat on their foreheads. What does the disappearance of the alien spaceship mean?

Just a few days ago, people could no longer see the spaceship through infrared light, that is, the alien spaceship had been repaired. If it is deliberately hidden, humans will lose its vision and can only see it when it is very close!

"Are you sure this is Sedna?" Yu Yifeng asked in disbelief.

"Yes...This is indeed Sedna, it should be it!" Several people confirmed it again and again. This kind of astronomical common sense, they can't make a mistake.

"But where is the spaceship? Where is the alien spaceship!"

Xu Yunjin has already shouted anxiously, he did not see the other smaller circle.

Yes, according to reason, there should be a smaller gravity source, that is, the huge alien spaceship!

Where did it go? !

Everyone searched the image several times, and indeed did not see the appropriate small circle near Sedna. And in the image, there are hundreds of small gravity sources, and it is impossible to distinguish which one is the alien spaceship and which are meteorites.

A chill rose from the bottom of his heart, and Yu Yifeng was so anxious that his hair almost stood up, and he even wanted to issue an emergency order!

"...Maybe it's a problem with the search range?" Professor Thomson also looked incredible, with fine beads of sweat on his forehead.

"Could it be...they are too close and their gravity overlaps? This is possible..."

The crowd spent another hour to start targeted inspections, eliminating those small gravity sources one by one, and indeed...no suspicious traces were found!

"They are all meteorites, not alien spacecraft. Maybe that's the case, the gravity of the two overlaps, and the alien spacecraft is still on Sedna."

After checking these, many members of the Ministry of Public Security breathed a sigh of relief. This may be an explanation, but it can't make everyone completely relieved. After spending so much time, there is still no observation of alien spacecraft, which makes everyone feel a little helpless.

Professor Thomson said again: "The propagation speed of gravitational waves is also the speed of light, that is, what we see is almost the situation 12 hours ago. If it leaves Sedna, we will definitely be able to observe a small circle...Yes, it must be like this."

Yu Yifeng frowned, there is no way. In the vast universe, information lag is inevitable. In fact, it would be fine as long as humans don't see it flying towards Mars...

The situation has not yet developed to the worst, he felt a little relieved and patted Xu Yunjin on the shoulder: "Old Xu, this is left to you, be sure to monitor it 24 hours a day, and notify me directly if there is anything."

At the same time, he turned his head and said: "Professor Thomson, you will be responsible for the maintenance of this telescope, is it okay?"

Xu Yunjin saluted immediately and replied solemnly. But Professor Thomson seemed to be stunned, staring straight at the observation image, and said stiffly: "Something is wrong!"

Hearing what he said, Yu Yifeng and Xu Yunjin immediately became nervous, "What's wrong?"

Professor Thomson seemed to be stunned, and kept calculating for a long time, and finally slowly said: "I just adjusted the parameters and expanded the search range... Look!"

Everyone looked up in confusion, only to see... a small sphere appeared near Sedna, tightly attached to it. However, its gravitational strength is more than ten times that of Sedna!

Professor Thomson said blankly: "This is... a spaceship of the Green Light Civilization? Is the mass of the other party too large? Even larger than the planet Sederna?!"

"The mass reaches 10^21 kilograms! This... is impossible!"

Professor Thomson's face was sweating, and he seemed to be talking to himself: "I mean, the mass of this spaceship is ten times larger than that of Sederna?! This is absolutely impossible!"
