More than ten minutes later, Burke came up with an accurate measurement.

Using remote sensing satellites, it was measured that the diameter of the sinkhole where the Y celestial body is located is 200 meters, the cross-section is circular, the radius is exactly the same, and the measurement error is plus or minus 0.1 meter. The highest point of the Y object is fifty meters above sea level, and if the diameter of the Y object does not change, its sphere is at sea level, and the measurement error is plus or minus zero one meter. Burke emphasized that the error is only a systematic error of the measurement.

Obviously, there is a good chance that the center of the sphere of the Y object is at sea level, and it is not bad at all.

The meeting lasted for more than an hour before Stark called for a temporary adjournment to allow the already exhausted Chiefs of Staff to rest.

"Professor, what do you think?" Yang Fanglie did not rest, and now is not the time to rest.

Luo Jinyong shook his head, although he had a very bad premonition, but he knew that what he said would definitely have a great impact on Yang Fanglie, so he didn't dare to say nonsense.

"Mr. Yang, do you remember the conflict in the East China Sea three years ago?" Zhang Xiaogang saw that Luo Jinyong was thinking, and took the initiative to move to other topics. "At that time, the little devils were arrogant and domineering, constantly challenging the limits of our patience, as if they thought that with the Yankees behind them, they could eat us. The result? When our aircraft carrier battle group forms combat effectiveness and cruising around the East China Sea, the little devil will immediately be honest. ”

Yang Fanglie smiled, this was before the establishment of the Planetary Defense Council.

Just a year later, China and Japan reached a memorandum of understanding to keep the situation in the East China Sea intact, and law enforcement vessels from both sides patrolled regularly.

"There's another story." Zhang Xiaogang didn't laugh, indicating that he wasn't joking. "Back then, Pope Benedict asked Giotto to prove his worth as a great artist, and Giotto didn't paint, but just a circle, a circle that was perfect and without the slightest blemish."

"What does this mean?"

Luo Jin was taken aback and immediately said: "Lao Zhang is right, why didn't I think of it!" ”

"Professor?" Yang Fanglie and Luo Jinyong were in the same room, not separated by 108,000 miles.

"The story of Pope Benedict and Giotto is the key!" Luo Jinyong rubbed his forehead vigorously and said, "Geiotto used that circle to prove to the Pope that he is the greatest artist in the world. In the same way, extraterrestrial civilizations use this sphere to send us a message. ”

"What's the message?"

"Strength!"

Luo Jinyong nodded and said: "In Asimov's science fiction novels, there is also a similar story, that is, human scientists found a stone tablet left by a person on the moon, even if it is measured with the most sophisticated instruments, the side length of the stone tablet is exactly the same. ”

"This ......"

"We all know that there are no two objects in the world that are exactly the same, even if they are poured out of a mold, even if they are twins, there are subtle differences. The key is whether we have the right measurement tools. As long as the accuracy of the measuring tool is high enough, it can be found that even two rulers with the same scale are not the same length, and there will always be some gaps. Luo Jinyong paused slightly, and then said, "I bet that even if you use a nano laser ruler to measure, the radius of the Y celestial body in each direction is fifty meters, and there will be no error." In addition, even with an electron microscope that can see the structure of molecules, the surface of the Y object is absolutely smooth. ”

Yang Fanglie tightened his brows, and Zhang Xiaogang looked indifferent.

"Also, the center of the sphere of the Y object must be at standard sea level, and there will be no error in the slightest."

"The problem is that the sea level is not the same at various points on the Earth, and the Earth is not a standard sphere, but an ellipsoid that is close to a sphere."

"Even so, there is an average of sea levels at various points around the globe."

"This ......"

"If our technology is advanced enough, we will definitely be able to measure this standard sea level height, but unfortunately, we don't have such advanced technology." Luo Jinyong paused for a moment and said, "Just as we don't have a sufficiently advanced technique to measure the radius error and surface smoothness of the Y celestial body, the extraterrestrial civilization has used this extremely simple method to show us its powerful scientific and technological strength. ”

Yang Fanglie was silent, and Zhang Xiaogang was also silent.

This method seems simple, but it is incomparable. The huge gap in scientific and technological strength is enough to make scientists like Luo Jinyong disheartened.

"That's it." Yang Fanglie let out a long breath and broke the silence. "Zhang Xiaogang, you have to keep an eye on it."

"No problem."

At the end of the video communication, Yang Fanglie walked to Luo Jinyong's side. "Professor Luo, I asked Wei Longzheng to arrange a room for you, you go and rest for a while. In any case, it will take more than ten hours for the Doomsday Force to reach the island of Amsterdam, and nothing can be done now. ”

Luo Jinyong nodded, he was indeed tired.

At this time, Zhang Xiaogang was rushing to the US military airfield.

After the earthquake, the U.S. military repaired the runway as quickly as possible. In accordance with the decision taken by the Council of Chiefs of Staff, Diego Garcia will remain the base camp of the Planetary Defense Council, and the countries will send people to replace those injured in the earthquake and deliver the essential supplies needed.

The first transport planes of the US military have already arrived, and the transport planes sent by China are about to arrive.

Because most of the infrastructure at the airfield has not been repaired and there is no place for the transport planes to stay, the transport planes will take off immediately after unloading personnel and cargo, and then meet with a large tanker sent by the US military nearby to obtain the fuel they need to return home.

When Zhang Xiaogang came to the airport, the first Y-20A had already landed on the runway.

Yuan Dezhi sent three transport planes, more than 100 guards and 78 scientific research personnel, as well as more than 100 tons of various materials and equipment.

To care for the wounded, there were also several medical personnel on board each transport plane.

The people waiting for evacuation have arrived, and Zhang Xiaogang greeted them one by one. Several of the guards, who had been slightly injured, wanted to stay, but Mr. Zhang did not agree.

After the transport plane unloaded the cargo, Zhang Xiaogang put the first batch of evacuees on the plane.

Seeing off the last evacuee, Zhang Xiaogang gathered the replacement personnel. Yuan Dezhi is very efficient, and there are seven female scientific researchers and four female guards among the replacement personnel, and they are all young and beautiful, which fully meets the requirements put forward by Zhang Xiaogang.

Next, Zhang Xiaogang took them to the camp of the Chinese, and then asked the remaining guards and researchers to take them to familiarize themselves with the working environment.

After all this, Zhang Xiaogang returned to the Security Affairs Liaison Office.

Replacement personnel are being arranged in various countries, so the Security Liaison Office is not so lively, it is much less staffed, and it seems a bit deserted.

Usually, this is definitely the liveliest place in the whole of Diego Garcia.

Hundreds of intelligence officers from ten countries are working together, and it is no wonder that they are not lively.

Zhang Xiaogang did not go back to his office, but went to Smith's office. U.S. replacements have arrived, and Smith should be in his office.

Thinking of the special task arranged by Yuan Dezhi, Zhang Xiaogang was a little big.

Although Zhang Xiaogang's talent has long been recognized, otherwise he would not be qualified to become a Chinese commissioner, the commissioners of other countries, and even the staff of the Security Affairs Liaison Office, without exception, are the best intelligence personnel of each country, and all of them are not simple.

It is harder to dig out information from their mouths than to reach the sky.

It's just that Zhang Xiaogang has no choice.

Smith was in his office, watching a news report from the network television station.

Although global earthquakes have paralyzed all submarine cables and submarine fibers, and tsunamis caused by impacts and earthquakes have made it difficult to repair submarine communication lines, communications satellites have been minimally affected, and the Planetary Defense Council has long established a global satellite communications network. Even though the communication efficiency is far less than before, but the communication is not interrupted, and the outside world can still be received.

Smith is following the disaster in Japan.

In the midst of this catastrophe, Japan was the real hardest hit area.

It's been a few hours, and the super tsunami has already swept across the Japanese mainland. In addition, impact-induced strong earthquakes and volcanoes that erupt after an earthquake have turned Japan beyond recognition. On the latest satellite photographs, the shape of the Japanese mainland has changed dramatically. As the Pacific Plate moves northward, Hokkaido and Honshu Island are separated from the central part of the island, and one-third of Hokkaido has sunk below the surface of the sea, and the northern part of Honshu Island, the Boso Peninsula, and the most densely populated Kanto region have all sunk to the bottom of the sea.

On the big screen hanging on the wall, Mt. Fuji is erupting, and the smoke rises 10,000 meters into the air, and the red magma sprays into the air like squeezed ink, and several lava streams gush out of the crater. However, Mt. Fuji is no longer the tallest mountain in Japan, but an isolated island in the sea.

Zhang ...... What are you doing here? ”

"How's it going?" Zhang Xiaogang is very casual, it seems that this is his office.

"Very bad." Smith handed Zhang Xiaogang a pack of Marlboros on the table. "Before the tsunami arrived, there were some survivors. When the tsunami came, all of these survivors were submerged. Some people fled to Mt. Fuji and may still be alive now. ”

"Is this a live report?" Zhang Xiaogang declined Smith's kindness, and he brought a cigarette.

Smith nodded and said, "A CNN TV reporter took footage from a patrol plane. Reconnaissance satellites discovered a fault zone in the middle of Honshu Island, and we sent a patrol plane to gather information. If this fault zone continues to expand, I am afraid that Japan will sink to the bottom of the sea. ”

"Where is the fault zone?"

Smith pulled up a photo from his computer.

The fault zone stretches almost the entire island of Honshu, from Osaka Bay to Sendai, forming a large canyon that is more than 500 meters wide at its widest. The fog in the canyon after the influx of sea water concluded that the bottom of the canyon was hot lava and that the canyon was by no means confined to land.
