The Three-Body Problem: The Most Competent Wallfacer of All Time

Chapter 488

To be able to shield space radar signals requires a high level of technology.

Although the radars on modern warships are still called radars, they have little similarity to traditional radars.

Electromagnetic waves are no longer used to detect enemy targets, but gravitational waves are mainly used.

The detection method has long ceased to use the time-consuming echo method, but directly receives the gravitational waves emitted by enemy ships or celestial bodies.

Any celestial body in space has more or less gravitational force. Generally speaking, gravitational waves are emitted radially from the gravitational source.

So modern radars only need to receive these gravitational waves.

The principle is simple, but the receiving device requires a very keen "tactile sense".

Especially for celestial bodies with small diameters or enemy fleets, the gravitational waves emitted by them are very, very weak, and even most of them will be covered by the cosmic background radiation.

The solar system country has been focusing on gravitational research since a very early time, and the results it has achieved are likely to be higher than those of the Trisolarans.

Until the Solar System Federation was annexed by the Solar System Country, they did not develop a space radar with a range of [-] astronomical units, which shows how advanced the Solar System Country is.

In addition, modern radars will also determine the flight speed and flight trajectory of high-speed flying objects according to spatial changes within a certain range.

As long as it reaches one percent of the speed of light, it will generally cause subtle changes in the space they pass through, and the faster the speed, the greater the change.

If a flying object reaches the speed of light, for a modern radar beyond [-] astronomical units, it is like hanging on its forehead for it to see.

Receiving gravitational waves, and observing subtle changes in space, are the main means of modern radar.

If these observation methods are to be blocked, it is equal to the signal of gravitational waves, and the spatial variation in the area of ​​the radar range.

Neither Cao Yang nor Essinger knew exactly how difficult it would be to do so, but it should be very difficult.

Then the civilization that can set up such a barrier should be very advanced.

Since it is an advanced civilization, four or five days ago, the Silicon Stars and the human fleet chased each other and entered this strange galaxy. Why did this advanced civilization not respond at all?

Cao Yang immediately asked: "Is the real-time communication system still available?"

Communications Staff Ella said: "It can be used normally."

Everyone in the command room breathed a sigh of relief, that's good.

"Report the situation here to Qingnvxing immediately!" Cao Yang said again: "The whole fleet is scattered and advancing. There may be more than one enemy here, the Silicon Stars."

At this time, Yinhe No. [-] reported: "The detection of this planet has preliminary results. It is an terrestrial planet. It is preliminarily judged that there is no sign of civilization on this planet."

This news made the people in the command room breathe a sigh of relief, so the previous barrier is likely to be some kind of natural phenomenon.

Cao Yang squeezed his chin and asked Yinhe No. [-]: "What is your standard for judging whether there are signs of civilization?"

Yinhe No. [-] said: "There are three main indicators, one is the detection of metal distribution, the other is the detection of nuclear facilities, and the third is the detection of antimatter or dark matter.

"These three items are data that can be detected at a distance, and are one of the important criteria for measuring the degree of a civilization.

"According to the data detected by the command ship, there is neither a large concentration of metals on the planet, no signs of nuclear facilities working, and no signs of dark matter or antimatter being used.

"Even if there is civilization, it will only be a primitive civilization that has not yet mastered metal smelting technology."

Most of them didn't understand the meaning of Cao Yang's question, but the staff officers who understood the question and answer took the breath back just now.

The detection standard of Yinhe-[-] is completely looking at the stage of civilization and technology from the perspective of people on earth.

What if the other party is not following a similar technological path on Earth?
What if the other party has gone through the stage of using nuclear capabilities and dark matter energy?

So it is still not completely sure whether there is advanced intelligent life on this planet.

Subsequently, Yinhe-[-] generated a three-dimensional simulation image of the planet and its surrounding satellites on the main screen.

The planet has a total of three satellites, two large and one small. The diameter of the two large satellites is about one or two thousand kilometers, and they are all spherical stars.

And that small satellite actually looks a bit like a spinning top.

Just because it is too small, the generated three-dimensional simulation image is not very realistic, and Cao Yang and others cannot determine the shape of the small satellite.

Chief of Staff Essinger found: "Commander, there is an enemy fleet hovering around that small satellite, and other enemy ships seem to be trying to land."

Even if there is an advanced civilization, it seems that there is no embarrassment for the people of the silicon planet.

Cao Yang's first reaction was: "It actually landed."

In fact, the current situation is beneficial to the ships of the Silicon Stars, because the small fleet commanded by Cao Yang has already entered their range.

But it's also the fault here, they didn't actively launch an attack formation, instead they lingered at the asteroid, and instead wanted to land on the planet in front of them.

These actions are not very reasonable tactics.

Cao Yang stared at the main screen: "Looks like we're going to visit this planet too.

"The ships are ready to attack at any time! As soon as the silicon star's ship appears, shoot immediately!"

Now that the situation ahead is unclear, Cao Yang must be cautious and not dare to attack rashly.

But this fleet of Silicon Stars cannot be let go.

After more than half an hour, it was close enough to the planet that Yinhe-[-] took an optical picture of the planet.

Cao Yang ordered: "Zoom in on the position of that small satellite."

Yinhe-[-] zoomed in on the picture, and the small satellite was really a gyro-shaped cone with a wide top and a pointed bottom!
Ella asked curiously: "There are satellites of this shape? Is it an asteroid?"

Even an asteroid is unlikely to have such a shape.

Cao Yang squeezed his chin habitually: "I don't think this is formed naturally!"

Essinger reported: "Commander, it has been confirmed that the enemy warships have sent a small force to the gyro satellite, and most of the enemy ships have completed landing."

In addition, the planet still doesn't respond. From the pictures, it doesn't look like it has undergone large-scale construction, and the possibility of advanced intelligent life can basically be ruled out.

Everyone had a tacit guess in their hearts: the barrier was formed by the gyro satellite, and the gyro satellite should be the relic of an advanced civilization!
Another ruin?

A few minutes later, Cao Yang began to issue combat orders: "Create a battle sand table! All ships are ready for hand-to-hand combat at any time!"

Then he ordered Essinger: "You command ten warships, occupy the gyro satellite, and see what is so mysterious about that satellite!"

Essinger took the command to generate a local command platform on the side of the captain's room, skipped the wartime platform, directly commanded ten warships, and pounced on the gyro satellite.

On the other side, Yinhe-[-] forms a three-dimensional image sand table, and the situation between the enemy and ourselves is clear at a glance.

Cao Yang ordered: "Captain Kakari, the battleship Taibai, is the commander-in-chief of the former enemy! Immediately attack the enemy on the surface of the planet in low-earth orbit, and do not give the enemy any respite!"

"The monster cannon is being assembled in low-Earth orbit and is always on standby!"
