Just as the era of the tech blowout began, something unexpected happened...

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

Astronomers generally believe that the Oort cloud is a remnant that formed the Sun and its planets 5 billion years ago and encircles the solar system.The Oort Nebula is the birthplace of comets.The distance from the Sun is about 50,000 to 100,000 astronomical units, which is roughly equal to one light-year, that is, one-fourth of the distance between the Sun and Proxima Centauri.

The light of the sun has been very weak at this distance, not as bright as Sirius, and it has really become an ordinary member of countless stars.

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

At this moment, a huge spacecraft about 150 kilometers in diameter is passing here, and if a human scientist stands in the spacecraft, he will be surprised to find that it exceeds the speed of light!

Its surface is wrapped in a bubble-like film, and strange bending occurs when the light shines on the ship.It is flying to the solar system at a much faster speed than the speed of light!

This superluminal motion does not violate any known laws of physics, and the best explanation is “curvature navigation.”

The curvature navigation, by changing the way of space curvature to let the object forward, is essentially the movement of space.Like a person standing on the carpet, when twitching the carpet, people will also follow the "movement".However, the motion of space is more abstract and more complex, and the spacecraft wrapped in the space of motion is almost stationary, and does not violate the relativistic effect, so the curvature navigation can theoretically reach any speed, even beyond the speed of light!

This has always been the space technology in the human imagination, but it has been completely realized in this spacecraft.If human scientists see it, it will inevitably trigger a crazy wave of research!

Beyond the speed of light is the best dangerous way to circumvent an interstellar civilization, because it creates a lot of confusion over information.

Looking at the faster-than-light spacecraft from all angles will also come to a different conclusion:

If you look at the back of the speed of the speed of the speed of the spacecraft, people will be surprised to find that the speed of light is still the speed of light.However, at this time, there will be a serious Doppler effect, and all the signal wavelengths will become larger and the frequency will become lower, that is, the observed spacecraft will be very bleak.

If you observe from the side of the direction of motion, depending on the angle, the situation will be even more strange: the ship is pulled into a strange long bar, and it is getting longer and longer, like a long noodle.

If the speed of the ship is much higher than the speed of light, people will see a discontinuous point, and then these points slowly connect together, forming a long noodle.

According to the first and last point, this is also the only case where it is possible to “see” faster than the speed of light.However, this phenomenon is very demanding from the observer's point of view.

If the observer is standing in front of the direction of the spacecraft, people can't see any images of the spacecraft!Because it is so fast, it throws all the light behind!

Only after a while, the ship passed by, people would see a ship passing through the eyes, away at the speed of light.At the same time, another backward image was produced, which looked like a video played upside down, and people would see the ship fly back to the original point at the speed of light!

This seems inconceivable, but it is not a time-lapse, and in essence, a parallax illusion from the speed of light.All observations, people see is not the spacecraft itself, but an image formed by light.

Because the speed of the ship exceeds the speed of light, when the spacecraft passes by the observer for a period of time, the recently emitted photons will pass into the human eye, then a little light behind, and then a little light behind, and the whole continuous image will look as if the ship is going backwards.

Strange observations have made objects faster than the speed of light a ghost phenomenon, and all observations based on light are lagging and inaccurate.

Therefore, this information is wrong, but it is the best umbrella for interstellar civilization!Because you don’t know where the superluminal spacecraft flew, unless... there is a faster way to observe than light!

The massive ship continued to travel a long distance in the Oort Nebula before it emerged from a state of faster-than-light and flew at a sub-light of light.

At this time, you can vaguely see its real face, it is a huge black elliptical sphere, the surface of the potholes, from time to time produce a lot of electricity sparks ... even, in the moment of breaking out of the speed of light, but also a violent explosion!

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 very weak radio wave with some kind of regularity, and he frowned and examined, some doubting whether the airwaves had been sent out by human civilization.Because it’s so regular, it doesn’t seem like it’s coming from the universe.

"Astronomy", as Noah's key support project, has also been taken care of by a large number of resources.Humans even plan to build a one-kilometer-diameter radio telescope on Noah!However, because of the lack of manpower, it is only a plan for the time being and has not yet been implemented.

Of course, small radio telescopes have already been brought from the lunar base, and Professor Thomson is the overall responsibility of this astronomical laboratory.

He carefully pondered this array of radio waves, not very long, but with obvious traces of intelligent civilization, six of which are consistent, and two repeated bands, which look like a string of information codes.

Tomson and his student Thomas kept experimenting, trying various decoding methods of humans, only to find that there was no way to understand it.

“There’s no such code, is it strange?”Is it a mess, and it’s still encrypted?”Professor Thomson muttered that this string of garbled codes seemed to be from space.

Suddenly, his student Thomas shouted, “Teacher, it’s up again, it’s there again!”At the end of the day, Thomas’s two eyes widened and seemed sluggish.

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

Seventy-three pages!

They were both shocked, what was it?

Thomson's fingers quickly tapped the keyboard, although it was impossible to locate the source of the radio wave.But with the intelligence now, he can be sure that it came from beyond Pluto!

Radio waves from beyond Pluto, and logically?What does that mean?

The two of them jumped in their hearts, and Thomas said with a pale face, “Are aliens coming for revenge?”

“Don’t be blind!”Thomson scolded, his hands trembling and making a short report, which also came with a "extreme emergency" sign!

...

In the moment when Yi Feng received the report, he suddenly "cuckled" in his heart, and his mind fainted.In this moment, he thought of countless bad possibilities, sweat drops from his forehead...

What does this signal represent?Is it an alien civilization, or an alien civilization ship?

He licked his lips before he regained his calmness.Now human beings, although the peaceful development of more than half a year of science and technology, but digestion of alien technology not even one percent.When mankind encounters a real interstellar civilization, it must be a situation that is being hanged!

Or... with the removal of alien weapons, you can barely fight back for one or two, and then become an unstoppable lamb to be slaughtered.

“Call an emergency meeting!”He pressed the button in the captain’s room.At the same time, he immediately gave a few orders.

"Astronomic observation equipment to maximize!"

Turn off all radios, visible light signals, and recall all robots!And... invite all cryptographers to the scene, be sure to unpack this code!”

“Call Calvin too!”
