Chapter 151 Planetary Spacecraft

To be precise, what Yu Yifeng observed was a huge dot as big as the moon!

There are more than a dozen small dots around it. According to the calculation of the gravitational wave telescope, the diameter of each small dot is about 150 kilometers to 200 kilometers!

"Is there such a strange celestial body?" Yu Yifeng felt very confused, and he rubbed his eyes subconsciously.

The distance of 0.6 light years is very far for humans, even out of reach.

"Voyager 1" launched in 1977 is the farthest man-made spacecraft from the earth. It is about 17 billion kilometers away from the sun...

And one light year is about 9.46 trillion kilometers.

According to this calculation, the maximum distance explored by humans is... 0.002 light years. It is really hard to imagine how far away one light year is.

The universe, in contrast to this distance, appears to be even wider.

The position of 0.6 light years is the scope of the Oort Cloud. Human exploration of this nebula can be said to be almost zero. Therefore, the appearance of a moon-sized planet in that area should not be a big problem, at least it is not particularly surprising. Maybe the planet itself exists but has not been discovered?

But Yu Yifeng felt something was strange. Are the dozen or so small dots around it all meteorites, and... they are arranged in a row? Too neat, too regular, right?

Yu Yifeng frowned and calculated its speed. When he saw the result, his head was dizzy, as if he couldn't believe it. He was still stunned for a long time.

His hands trembled slightly, and he repeated the calculation again, but it was still the same result!

"What is this?" He shouted immediately. He would not make a mistake in such a simple problem. There must be something wrong with this dot!

Hearing Yu Yifeng's scream, a group of scientists who were thinking stood up and walked to Yu Yifeng's side.

When they saw Yu Yifeng's calculation results, they stood still again, as if they had witnessed an incredible scene...

Sub-light speed!

A bunch of sub-light speed spheres are flying into the solar system!

This is definitely not a star, but... a spaceship, definitely a huge spaceship! This is an extremely powerful fleet, the smallest one is 150 kilometers, comparable to the spaceships of the Green Light Civilization!

"What is this?"

"What's going on?!"

Some scientists exclaimed, and some people shouted, but apart from this explanation, no star can reach the sub-light speed level!

Although his mind was still in a state of shock, Yu Yifeng immediately issued a notice for an emergency meeting. At the same time, he asked Thomson and other astronomers to pay close attention to that area and try to use other methods to search for the super-large fleet.

…

"Everyone, this situation is very urgent, and we discovered it by accident. The speed of this fleet is about 0.6 times the speed of light. Although the gravitational wave telescope discovered them 0.6 light years away, the propagation speed of gravitational waves is also the speed of light, and the information is delayed. It can be said that this is a picture from 0.6 years ago!"

Yu Yifeng's face was livid, and he played the observation image on the screen. "The largest main ship in the middle is comparable in size to the moon, with a diameter of about 3,000 kilometers!"

"There are also 12 smaller spaceships, each with a diameter of 150-200 kilometers!"

At the end of the speech, his anxiety was almost uncontrollable, and he even punched the table heavily.

"A total of... 13!"

A super spaceship as big as the moon! This is almost something that only exists in science fiction novels, but now it has appeared in front of people alive, giving people an indescribable shock... How much time does it take to transform a planet into a spaceship, and how much industrial capacity is needed?

This oppressive feeling is the peak of human technology that is unimaginable at present!

Small!

Humanity is really too insignificant...

Yu Yifeng didn't know what this fleet meant. He also didn't know what purpose it had in coming to the solar system... He only knew that it was definitely not a good thing for humans!

There was a green light civilization in front, and another fleet behind? What was going on?

Sitting at the meeting were the main leaders of major factories, scientists, and relevant councilors. A pressure like Mount Tai appeared in everyone's hearts, making them breathless.

Everyone's face was livid, and they were anxious.

Fortunately... there was no collapse!

This was also the most gratifying point for Yu Yifeng. Over the years, humans have experienced too many crises, and their tolerance seems to have gradually increased. Whether it is the councilors or scientists, they are just thinking silently, not directly wailing in despair.

This is much better than two years ago, when people were still on the moon and the Noah Plan had not yet been implemented. The same group of people almost collapsed after hearing that the moon was about to be destroyed. It was only by Yu Yifeng's roar and roar that they were barely pulled back.

Yu Yifeng will always remember that scene, as if the sky had fallen, and everyone was so desperate and sad...

But now, this feeling has reappeared, but the situation is different. This is the progress of all mankind! It is always a good thing to be able to think, whether it is anxiety or anger, it is more useful than despair.

"It has to be said that any warship is not something that we humans can contend with..." As the leader of a civilization, Yu Yifeng suddenly felt a sense of sadness, or indignation, when he said this!

"We observed them in advance, and we must find a way in advance!"

People frowned. Facing such a powerful civilization, humans are really too humble and too small.

The dark universe, the boundless universe, contains countless crises, and any disturbance can destroy all mankind!

Technology, technology! We need stronger technology, even if... at all costs!

He coughed lightly and said in a serious tone: "According to our calculations, the fleet is still 0.24 light years away from Pluto... That is, in another five months, it will reach the position of Pluto!"

"We still have five months."

After saying that, he sat down and thought hard.

The matter seemed very strange... It would be fine if a green light civilization appeared to take refuge, but why did a huge fleet appear again? Was this the work of the green light civilization, or was there some other reason? Should we... continue to use the camouflage plan?

If the broken spacecraft of the Green Light Civilization can be frightened by humans, then... this huge fleet can never be frightened simply.

What to do? What to do?

At this time, Professor Thomson also received even worse news: "We have tried various methods, but we can't observe it at all. The other party seems to have maintained a state of radio silence... Moreover, there is almost no reflected light and thermal radiation. With our radio telescope, we can't see it at all!"

"No,... still no, we used a radio interferometer, but still can't see it. Only a gravitational wave telescope can do it!"

Yu Yifeng frowned when he heard it. He was a little depressed, but also a little fortunate. Fortunately, humans have gravitational wave telescopes that have surpassed several technological levels, otherwise... we can only know when the other party gets close, which is too dangerous!
