Annihilation of the solar system

In the past, when they calculated comet orbits and considered orbital influencing factors, they often gave an estimated value based on experience and calculated the approximate orbit.

Now Liu Chaowen's precise formula calculation method was something she had never seen before. She handed the paper to Yang Fan aside:

"Yang Fan, look at it. If your math ability is stronger, let's see if there is any problem with Chaowen's calculation."

Yang Fan took the paper handed over by Xia Lan and pushed up the glasses on the bridge of his nose:

"Well, this algorithm is a bit interesting. Are these variables calculated from multiple observations or empirical data?"

Liu Chaowen handed over several more sheets of paper filled with calculation formulas:

"It's all calculated based on the statistics of the Oumuamua orbital observation data. I have the calculation process here for you to take a look at."

Yang Fan was a little surprised. He took the information and sat back in his seat:

"Your computing power is so amazing. You can calculate so much data in these two hours! Wait a minute. I'll randomly pick out some data and check it. By the way, Mengzhu, didn't you also study mathematics in college?

, you come here and help me figure it out."

After hearing what Yang Fan said, others gathered at Liu Chaowen's table and picked up the remaining papers on the table and read them.

Wei Xu picked up the piece of paper with the orbit sketch and coordinate values ​​and thought about it for a while:

"You mean, Oumuamua should be here now?"

Liu Chaowen nodded, his words full of confidence:

"Yes."

Wei Xu held a cigarette in his mouth but did not light it. Looking at the dense data on the manuscript paper, he frowned:

"It is 3.5 astronomical units from the earth! It is a bit difficult for our telescope to see a celestial body of the size of Oumuamua. If the calculation is correct, we can also see a small black dot.

But that location is very close to the asteroid belt, and I’m worried that even if I see it, the background interference will be too great and I won’t be able to distinguish it.”

Xia Lan wasn't very sure either. She checked the data from the telescope:

"If the calculation accuracy is high enough, then theoretically we can distinguish it from other small celestial bodies in the background."

Lin Tianyu had already finished packing his materials, and he still had the same slightly frivolous tone as before when he sat in his seat:

"It would be very difficult to achieve that kind of accuracy in calculating the orbit of a celestial body like a comet."

Wei Xu put down the information and nodded:

"It's a little bit, but it's not impossible. Aren't Yang Fan and Mengzhu checking the calculations? There will be no problem after they finish the calculations. Let's take a look at the area and find out. It won't delay anything."

After saying that, he took out his lighter and walked towards the door of the observation room. Lin Tianyu had no expression on his face and said coldly:

"Well, I also want to see with my own eyes the power of genius."

Liu Chaowen didn't pay attention to this sentence and just continued to sort out his calculation data. Xia Lan on the side rolled his eyes at Lin Tianyu:

"Tianyu, it's your turn to be on duty tomorrow. You should go back to the dormitory and rest first. I and a few of them will help Chaowen take a look at it later."

There was a hint of embarrassment on Lin Tianyu's face, and his tone was a bit more conciliatory than the pride just now:

"There's no rush for this little time, I'll do it together with you."

Not long after, Wei Xu, who had thrown away the cigarette butt but still had smoke coming out of his mouth and nose, returned to the observation room. Xia Lan fanned her face with the paper in her hand and said angrily:

"Old Wei, can't you just blow out the last puff of cigarette before coming in? It's like this every time, it's really annoying."

Wei Xu looked embarrassed:

"Sorry, sorry, please be careful next time!"

Then quickly change the topic:

"By the way, Yang Fan, how are you doing?"

Yang Fan raised his head and made eye contact with Liu Mengzhu, who had just finished his calculations next to him:

"There is nothing wrong with the calculation itself, but I am not familiar with the formula introduced. Assuming there is nothing wrong with the formula, the result must be without any deviation."

Wei Xu took the piece of paper with the precise orbital position written on it and sat in front of his computer, typing on the keyboard.

Soon, a mechanical sound of "Wooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooong Telescope" appeared on the large screen in the observation room. As the focus was locked, a black background appeared on the image, with a faint blur on it.

There are about a few blurry bright spots, which are distant stars.

He clicked on the keyboard for a while, and the words "Start Scanning" appeared on the screen. Everyone waited with bated breath for the results. After a few dozen seconds, the system issued an alarm sound of "Beep!" "No similar celestial objects found."

The words appear on the screen.

Wei Xu looked at the paper in his hand and then at the computer screen. After some proofreading, he shook his head:

"According to Chaowen's calculation data, no celestial body of the size of Oumuamua has been found in this region of the sky."

Xia Lan put one hand around her waist, and with the other hand she held her pointed chin and thought for a while:

"Take this sky area as the center and search the surrounding sky areas."

Wei Xu nodded, sat down, and started working again.

Not long after, after completing the scan of the last adjacent sky area, the words "No similar celestial objects found" were still displayed on the screen. Several people were a little disappointed, only Lin Tianyu showed a slight disdain on his face.

Wei Xu put the piece of paper back on Liu Chaowen's desk and patted him on the shoulder:

"Brother, you did not find Oumuamua at this location. It may be that there is some deviation in your calculation, or it may be that our telescope has difficulty capturing small celestial bodies at this distance.

'Oumuamua is not a long strip, maybe its smallest projected area relative to the earth is facing our observation point, so it will be difficult for us to detect it."

Xia Lan also walked to Liu Chaowen and comforted:

"It's okay, Chaowen. I'll ask Lao Wei to help you take a look at it later when today's sky survey project is about to end. The accuracy of observations at this distance varies greatly."

Liu Chaowen looked calm, as if this result had been expected. Then he picked up another piece of information from the table and handed it to Xia Lan:

"Sister Lan, take a look. This is a set of calculations I reorganized based on the data of Oumuamua's orbit around the sun. I calculated that his current position should be here."

Xia Lan took the paper from Liu Chaowen and took a closer look. A puzzled expression immediately appeared on her delicate face:

"Chaowen, I just took a rough look at the calculation process. But this result deviates from your result just now by about 1.5 astronomical units. This is not reasonable. How can there be such a large orbital deviation."

Yang Fan took the paper and looked at the calculation process line by line. Liu Mengzhu, who was on the side, almost touched Yang Fan's head to watch. After a while, Liu Mengzhu said in a delicate voice:

"The calculation method is basically the same as before, except that the numerical deviations quoted on the variables that affect the orbit are very large. Chaowen, can you tell me why these values ​​are added?"

Liu Chaowen didn't speak for a while. Yang Fan scratched his head and looked at the data on the paper:

"There's nothing wrong with the calculation, it's just what Mengzhu said. This mathematical model looks like...well...my metaphor may not be very reasonable...just like there's an engine on Oumuamua.

, it’s like it suddenly started to adjust the track half a month ago...Nothing else, Chaowen. It’s just an example.”

At this time, Lin Tianyu stood up from his seat, gently arranged his exquisite hairstyle, and said with a chuckle:

"Haha, junior brother, it turns out that you are also the group that believes that Oumuamua is an alien spaceship. But it doesn't matter. Didn't Mr. Hawking say that you must remain curious on the way to scientific research? Keep up the good work. I'll go first.

Go back to the dormitory and rest."

The almost mocking tone of the words made Yang Fan, the most insensitive person, already understand what Lin Tianyu meant, and the atmosphere in the observation room was a bit awkward. Liu Chaowen's face was still as calm as before, and was not affected by Lin Tianyu's words.

.

Wei Xu strode up to Yang Fan, grabbed the piece of paper with the data on it, and returned to his computer. He entered the data on the computer with both hands, obviously much more vigorously than before:

"Why are you talking nonsense like this? This telescope is right in front of you. Why don't you just turn it over and have a look?"

After inputting the data, Wei Xu vigorously pressed the Enter key and the "Pah!" sound was particularly obvious. The telescope next to him made another "Woooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo According,

Specks of time appear and disappear from one side of the screen, like luggage on an airport conveyor belt.

Lin Tianyu had already packed up his things and walked to the door of the observation room. He might have stopped somewhere because of curiosity or other reasons.

Amid everyone's expectations, the screen stopped moving. After a short focusing process, the content displayed on the screen was not much different from before. Only the position and number of several blurry bright spots representing distant stars changed.

Wei Xu entered the command to start scanning, and almost at the same time he pressed the Enter key, the system sounded a beep!

Everyone stared at the screen with their eyes wide open, because the sound meant that a suspected celestial body had been discovered.

After a few seconds, a red box appeared on the screen, locking a small dark dot on the screen that was difficult to see.

Wei Xu then operated the telescope and zoomed in on that area. When it was enlarged to the entire screen, everyone couldn't help but exclaimed!

Although what is displayed on the screen is a bunch of blurry pixels, the basic shape can be seen as a long celestial body.

A line of text appears on the screen:

"Find a celestial body with a similarity of 70%, with a length between 300-500 meters and an unmeasurable width. It is 3.418 astronomical units from the earth!"

The air in the observation room seemed to be condensed at this moment. Everyone present stood speechless looking at the blurry pixel graphics on the screen. Lin Tianyu who walked to the door put down his backpack and walked in to take a closer look.

Look at the enlarged picture.

Everyone has the same question in their mind:

"Why is this comet here?"

Only Liu Chaowen sat in his seat with a calm expression, as if everything was beyond his expectation.
