"…0.4 times the speed of light is too fast, even if controlled nuclear fusion technology is used, it cannot be achieved, because nuclear fusion can only use about 7% of the mass of the matter at most!"

"Yes, according to our existing theory, nuclear fusion can only drive the spacecraft by one-tenth of the speed of light, no more than 15% at most!"

"But they really reached such a speed... there must be more advanced energy, such as antimatter energy, or a more effective driving engine - the curvature engine."

The monitoring and observation room is always the most lively place on Noah, with a large number of scientists staying here all day long, arguing and discussing. They want to find clues about this alien spacecraft. Any little information is crucial to humans.

"See, I see it!" An astronomer suddenly screamed. He quickly typing on the keyboard, and a large number of images flashed out of the computer screen.

In the astronomical photos in recent minutes, an extremely blurred black dot finally appeared. If it weren't for infrared rays that had discovered it, humans might have directly ignored it. This black dot is probably only the size of a few pixels, and even the boundaries are blurred, but it does not hinder the scientists' calculations.

A group of people immediately sat in front of their computer excitedly. They simulated and inferred several photos from different angles through the simulation screen of the Noah central computer. After calculating their shape, location, direction of movement, etc., they finally obtained several possible restored images.

This is……

What a huge and magnificent space warship!

It is an elliptical sphere with a diameter of about 150-200 kilometers. It is really too large. The diameter of light is more than 10 times that of Noah, and the volume is more than 1,000 times!

It's strange that the light has twisted and twisted on the surface of this spacecraft, so that humans can't estimate its specific size at all.

"How is it?" Yu Yifeng also received the news and rushed over immediately. When he saw the simulation picture on the screen, he was immediately stunned. Such a size... Just this size is enough to have a sense of oppression on humans. This is an existence that human technology cannot imagine.

If this spacecraft lands on Earth, it can cover 70 New York City skies! It can completely exterminate humans in one day...

No, maybe it only takes a few hours. Humans cannot go to war with such civilizations. There is more than 90% chance of surrendering directly. As long as these aliens do not massacre humans in an extinction...

"Do it!" Yu Yifeng cursed in his heart. Such a giant might really destroy a planet!

They didn't know the size of each other in advance. If they knew that they were so abnormal, what kind of disguised plans and intimidation plans might not be implemented. However, all the plans could only be implemented with the help of the radio waves and the water splashed out...

Seeing other scientists silent and seemingly weakened their confidence, Yu Yifeng couldn't help but say, "This should be the other party's main ship. Only such a huge spacecraft has complete functions and can support a large number of people..."

"Have you found anything else?"

An astronomer suddenly came to his senses, pointed to a photo and said, "Looking at this location, maybe there is really something wrong with it!"

Yu Yifeng squinted his eyes and looked carefully. This was an infrared photothermal image. A large amount of red light appeared on the right side of the photo, indicating that a large amount of heat energy overflowed in this part. It was these overflowing heat radiation that made humans discover this alien spacecraft!

what does that mean?

Since humans received several radio waves, they have never received them again. It is likely that the other party repaired the vulnerability. However, this large-scale thermal radiation has always existed, that is, it has not been repaired.

This is definitely an abnormal manifestation!

"The spaceship may have really been damaged!" This was Yu Yifeng's first intuition.

He felt that what Dr. Rambo was probably right, why didn't the other party repair it? It lacked manpower, or... lacked resources! They hurried to the solar system just to repair their spacecraft!

In this way, humans' camouflage plan is still very likely to succeed! The other party's spacecraft is broken, do you still have the ability to start a war?

He held his palm tightly, and his strength even imbedded his nails deeply into the flesh. But he didn't pay any attention, because his whole mind had already turned to the picture he was observing in front of him.

...

This period of time has been so tormenting.

People waited anxiously for two more days, and it was exactly 10 o'clock in the evening, but all the scientists were discussing it without any fatigue.

It has been more than sixteen days since the radio was launched. In another ten hours, it will be the expected time, and people will see the other party responding to radio waves.

Should I open the fire directly? Or...

If the other party uses the means of light-speed strike, as long as people observe the attack image, their side will be hit and there is no time to react. (In fact, human telescopes cannot see the details of the attack image at all).

Excited, panic, nervous... There are all kinds of emotions, everyone's eyes are red, and there are a few who haven't slept for several days, but they still insist on seeing the first scene when the other party received the radio signal.

Of course, Yu Yifeng is also one of them.

He pricked up his ears and heard the roar of Dr. Rambo from afar. Rambo seemed to be in the optimist position every time: "What are you afraid of? I tell you, every interstellar civilization has such a big spacecraft... When we really enter the interstellar, we can do it too!"

"It's useless to have a big size. Can they destroy the Noah? I absolutely don't believe it!"

But it seems that this is true. Noah is a magical spacecraft, which can be said to be extremely hard. Even if the other party fires and the laser can hit it, he will definitely not believe that Noah will lose a hair...

However, human facilities will be completely destroyed, and the expense will be revealed at that time... But since the war has begun, are you still afraid that the expense will be revealed?

In fact, what Rambo said makes sense. The development of technology is leapfrog. Humans can barely imagine what technology will look like in twenty years, but it will be difficult to imagine in fifty years... Maybe, the other party is only one or two hundred years ahead of humans?

In this way, during the constant quarrel, people's mood became increasingly nervous. Whether the universe is a dark forest, peace or war will be revealed in a few hours...

In this situation, who can not be nervous? Who can not be afraid?

Until seven o'clock in the morning, the breakfast food had been delivered to all personnel. No one was thinking about breakfast at this time. They just swallowed a few bites and stared at the screen.

Time passes minute by minute...

"Didi, Didi!" A countdown alarm suddenly rang. According to calculations, the picture of the other party receiving the radio should have also been transmitted!

"Why are they not responding? Did they fire? No, we didn't seem to be hit!" a scientist shouted anxiously.

"Don't worry, you have to make people have some reaction time."

Yu Yifeng also swallowed hard, but in fact he was so panicked.

"It seems they slowed down?!" an astronomer suddenly pointed to the screen and said, "It's not right... I'm wrong." He made a mistake several times and quickly rejected his own veto.

In fact, at such a short time, with human measurement accuracy, it is difficult to calculate the other party's speed change state, especially when the speed is extremely high.

However, humans were not hit and the other party seemed to have no reaction. What's going on?

One hour, two hours... Just as people were getting more and more unable to wait, the whole screen suddenly shook with a "sniff..."

A radio expert shouted wildly, and this time he was really yelling loudly, "Radio wave! It's radio wave!"
Chapter completed!
