Everyone could hear Cheng Xiang's speech clearly, but the content of what he said made everyone confused.

"Mr. Cheng, I understood 100,000 years ago, but this is just a starry sky map. How do you know it is Mars?" Some researchers couldn't help asking a question.

This question is also a common question for everyone in the Control Center at this time.

Grab and snatch. Faced with doubts, Cheng Xiang smiled and didn't care, "It's very simple."

"After discovering this box, I spent my spare time looking for a space center to come to a part of the astronomical astrological maps that the Earth can directly observe, so as to learn about the universe information currently observed by humans."

"With the astronomical observation map on Earth, as long as you are familiar with the trajectory of the solar system and its internal planets, and after some simple transformations, you can get the astronomical astrological map on Mars. If you push back 100,000 years, it will be almost where you are now."

Information experts: "…"

This topic is really beyond the scope for their group of researchers who are engaged in information processing.

It's still simple, it's reversed by 100,000 years.

That's right, theoretically, if you know the current starry sky trajectory diagram above the Earth, and then know the earth's trajectory, Mars' trajectory and the solar system trajectory, you can indeed infer the astronomical starry sky map on Mars 100,000 years ago.

However, this is not to solve a one-element equation, and to simply transform left and right sides of the equal sign.

This is the transformation of the astronomical starry sky chart. The position of each star is a variable. It is easy to calculate so many positions, so it is easy to say that it needs to be calculated with paper and pen.

Could it be that you can really simulate it in your mind?

I have heard of those who can directly solve mental arithmetic polynomial equations, but I have never heard of mental arithmetic astronomical astrology charts.

However, some people still want to ask more clearly, "Mr. Cheng, can you tell the exact year?"

"Which year is from?" Cheng Xiang looked at the picture, and after about a few seconds, Cheng Xiang shook his head.

After shaking his head, everyone finally breathed a sigh of relief. It was still relatively normal. If they really revealed the years in one breath, they felt that they were dreaming and not awake.

However, before he could finish his breathing, Cheng Xiang spoke, "I can't do the specific year. After we project and cut the figure, the position of this figure will eventually be somewhat deformed, but it can be determined about 125,700 to 125,800 years ago."

"If we had direct restore projection equipment, we might be able to accurately reach the specific year."

“…”

The control center was full of silence.

Mr. Cheng, you have to be a person. It turns out that your head cannot accurately locate that year.

Everyone looked at each other. Is Cheng Xiang’s conclusion true or false?

When Cheng Xiang saw the expressions of everyone, he could not understand what everyone at the scene thought. After thinking about it, he said, "You must know whether my inference is correct or not, and verification is also very simple."

"The space center should have corresponding simulation software."

六文版版版版.org 六文版. "Director Ding, please find the space center and ask for the astronomical astrological map of Mars 125,800 years ago to 125,700 years ago. By the way, I also estimated the location of the observation point, which should be in the range of 30,000 to 40,000 kilometers from the surface of Mars."

Ding Qing: "..."

This person is really awesome, and his observation position is directly estimated.

"Okay. Now." Ding Qing took a deep breath and then acted immediately.

Although this is just a reason, it is undoubtedly a top priority to determine the specific year in the video.

Ding Qing went to contact us and handled the special matters. The priority level of the underground secret research institute is high enough, so in just about five minutes, Ding Qing had already returned with an encrypted mobile hard drive.

"Okay!" Ding Qing handed the mobile hard drive to the researcher on the operating table.

Insert, import data.

"There are 1,200 pictures inside, which are astronomical astrological images when Mars is facing the sun between 125,800 and 125,700 years ago."

"One thousand two hundred pictures, one for each month." Ding Qing briefly introduced.

"very good."

"Let's get started."

The operator immediately displays the picture onto the large screen.

There are thirty-six pictures in one screen, except for one original picture, the other thirty-five pictures are only three years away.

This was revealed, and everyone immediately discovered it.

"It seems to be quite similar"

"Similar? This is more than just a similarity? This is almost a picture! The Milky Way rotates around about 300 million years, and the changes in astronomical astrology in 100 years are very small."

"Although the image we have obtained has been deformed a lot, it can be confirmed that this is indeed a picture."

"So, Mr. Cheng's speculation is completely correct?"

"It's really correct!"

Everyone fell into a speechless state again.

"I have really gained some knowledge. On weekdays, I think I have good mental arithmetic skills, so I can also calculate my advanced math problems directly for my kid. But Mr. Cheng." The man shook his head vigorously.

"Who isn't? I understand. There can be a big difference between people. They are the same head, but they are different."

"Give me a star map like this, I really can't see anything except looking at the stars."

"Haha, who is not?"

The answer verifies that Cheng Xiang’s inference is correct, and everyone’s conviction with Cheng Xiang is further improved.

"Director Ding, the time has been basically determined. Let's continue to the next step."

"good!"

The next moment, another frame of projected pictures in the gene storage information was sent to the large screen, with 36 new pictures, but it was almost the same as the previous batch of pictures.

Ding Qing frowned: "The two frames of pictures are too close."

Cheng Xiang frowned slightly when he saw this, "It's really too close, but this is video information, so this is inevitable."

"I hope the number of frames they record per second is not too high. If the number of frames is too high, then the amount of information we can obtain under the limited amount of data will be too little."

"That's right, Chengsu, we can only hope that the frame rate is not too high." Ding Qing was very worried.

"The image data of each frame of the immersive 3D image is very large, almost one frame is 1GB of data. From the discovery of the box to the present, the total amount of data received through electromagnetic waves is about 16TB, and some system data and other structural information are removed."

"The total amount of image data that is really used to store is only 12TB." Ding Qing calculated quickly.

"A picture with 1GB and 12TB is only 1200 pictures at most. Among the 1200 pictures, there may be a lot of missing and incorrect data."

"There will be less useful. If the refresh rate of alien creatures recorded is 60 frames per second, then we may have less than 20 seconds of information."

20 seconds!

This is only a case of 60 frames per second. If it is higher, there is no doubt that this time will be less.

"I hope I can discover some useful information."
Chapter completed!
