Chapter 125 Signals From Outer Space

Just when the great era of technological explosion had just begun, an unexpected thing happened...

This is the Oort Nebula, the outermost part of the solar system.

Astronomers generally believe that the Oort cloud is the remnant material that formed the sun and its planets 5 billion years ago and surrounds the solar system. The Oort Cloud is the birthplace of comets. It is about 50,000 to 100,000 astronomical units from the sun, which is almost equal to one light-year, or one-quarter of the distance between the sun and Proxima Centauri.

The sun's light is already very weak at this distance, not as bright as Sirius, and it has truly become an ordinary member among countless stars.

The fastest light takes more than a year to reach here from the sun. Therefore, the comets here take millions of years to orbit the sun, and they can only be seen when they run hundreds of millions of kilometers away from the sun.

At this moment, a huge spacecraft with a diameter of about 150 kilometers is passing here. If a human scientist stands inside the spacecraft, he will be surprised to find that its speed exceeds the speed of light!

Its surface seems to be wrapped in a bubble-like film, and when light shines on the spacecraft, a strange bending phenomenon occurs. It is flying towards the solar system at a speed far exceeding the speed of light!

This kind of super-light motion does not violate any known physical laws. Its best explanation is "curvature navigation".

Curvature navigation allows objects to move forward by changing the curvature of space. Its essence is the movement of space. Just like a person standing on a carpet, when the carpet is twitched, the person will also "move". However, the movement of space is more abstract and complex. A spacecraft wrapped in a moving space is almost stationary and does not violate the effects of relativity. Therefore, curvature navigation can theoretically reach any speed, even - beyond the speed of light!

This aerospace technology that has always been imagined by humans has been completely realized in this spacecraft. If human scientists see it, it will inevitably trigger a wave of crazy research!

Going beyond the speed of light is the best way to avoid danger for interstellar civilizations, because it will bring a lot of confusion in information.

Observing the super-light spacecraft from various angles will lead to different conclusions:

If one observes from directly behind the direction of the super-light spacecraft, people will be surprised to find that the speed it moves away from is still the speed of light. However, a serious Doppler effect will occur at this time, and the wavelength of all signals will become larger and the frequency will become lower. In other words, the observed spacecraft will be very dim.

If you observe it from the side in the direction of movement, depending on the angle, the situation will be even more bizarre: the spacecraft is stretched into a strange long strip, and it gets longer and longer, like a long noodle.

If the speed of the spacecraft is much greater than the speed of light, people will see discontinuous points, and then these points are slowly connected together to form long noodles.

Based on the first and last points, this is also the only situation where it is possible to "see" superluminal motion. However, this phenomenon has very high requirements on the observer's perspective.

If the observer stands directly in front of the direction of the spacecraft, people...can't see any image of the spacecraft! Because its speed is too fast, it leaves all the light behind!

Only after a period of time, when the spacecraft passes by here, people will see a spacecraft passing in front of them and moving away at the speed of light. At the same time, another backwards image is also produced, which looks like a video played backwards. People will see that the spacecraft flies back to the origin at the speed of light!

This situation seems incredible, but it is not going back in time. In essence, it is a parallax illusion caused by super-light speed. In all observations, what people see is not the spacecraft itself, but images formed by light.

Because the speed of the spacecraft exceeds the speed of light, when the spacecraft passes by the observer for a period of time, the recently emitted photons will be transmitted to the human eyes, then the light a little behind, and then the light a little behind, the whole continuous The image looks like the spacecraft is moving backwards.

Various strange observation results have turned super-light objects into a ghost phenomenon. All light-based observations are lagging and inaccurate.

Therefore, this kind of information error is the best protection for interstellar civilization! Because you have no idea where the super-light spacecraft has flown, unless... there is an observation method faster than light!

This huge spacecraft continued to sail for a long distance in the Oort Nebula before emerging from the state of super-light flight and flying at a sub-light speed.

At this time, one can vaguely see its true appearance. It is a huge black elliptical sphere with pits and bumps on the surface. It generates a large number of electric sparks from time to time... and even produces a violent explosion at the moment of leaving the super-light speed!

Or because of this, it flew firmly into the solar system...

This is the solar system, Mars.

Professor Thomson, who was in charge of astronomical observations, suddenly detected an unusual fluctuation.

It was a burst of radio waves with a certain pattern, very weak. He frowned and checked, somewhat doubting whether this burst of radio waves was sent by human civilization. Because it's so regular, it doesn't seem like it comes from the universe...

"Astronomy", as a key support project of Noah, has also received a lot of resources. Humanity even plans to build a one-kilometer-diameter radio telescope on Noah! However, due to lack of manpower, it is only a plan for the time being and has not been implemented yet.

Of course, the small radio telescope already existed, brought from the lunar base, and Professor Thomson was the general manager of this astronomical laboratory.

He carefully pondered this burst of radio waves. It was not very long, but there were obvious traces of intelligent civilization. The six waves were consistent, and there were two repeated bands. It looked like a string of information coding?

Thomson and his student Thomas kept experimenting. They tried various human decoding methods, but found that they could not decipher it at all.

"There is no such code, strange? Is it a string of garbled codes, and it is encrypted?" Professor Thomson muttered to himself. This string of garbled codes seemed to come from space?

Suddenly, his student Thomas shouted: "Teacher, it appears again, it appears again!" At the end, Thomas's eyes widened and seemed to be stagnant.

Thomson hurriedly looked at the screen and saw that the radio telescope had detected a large amount of information coding! This time it was not a few paragraphs like last time, but densely packed... seventy-three pages!

Seventy-three pages!

The two were simply stunned. What is this? !

Thomson's fingers quickly tapped the keyboard, although he couldn't locate the source of the radio wave. But with the current intelligence, he could be sure that it came from outside Pluto!

Radio waves from outside Pluto, and they are logical? What does this mean?

Their hearts beat wildly in an instant, and Thomas said with a pale face: "Are aliens here for revenge?"

"Don't talk nonsense!" Thomson cursed, and his hands trembled as he typed a short report with an "extreme emergency" sign on it!

...

The moment Yu Yifeng received the report, his heart suddenly "clicked" and his brain was dizzy. At this moment, he thought of countless bad possibilities, and sweat dripped from his forehead...

What does this signal represent? Is it an alien civilization, or a spaceship of an alien civilization?

Yu Yifeng bit his lips tightly and barely regained his composure. Although humans today have developed technology peacefully for more than half a year, they have not digested even one percent of alien technology. When humans encounter a real interstellar civilization, they will inevitably be beaten!

In other words... with the dismantled alien weapons, they can barely fight back once or twice, and then become lambs to be slaughtered without any resistance.

"Convene an emergency meeting!" He quickly pressed the button in the captain's room. At the same time, he immediately issued several orders.

"Maximize the astronomical observation equipment!"

"Turn off all radio and visible light signals, and recall all robots! And... ask all cryptographers to come to the scene and make sure to decipher this code!"

"...Call Calvin too!"
