After Shan Yufeng asked everyone to disband, he took Li Ni to the Purple Light Pavilion. Pen & Fun & Pavilion www.biquge.info

"Tell me, what's wrong?" Boarding the dodo, Shan Yufeng asked.

"Here's the thing, humanity's evacuation plan is to go to the closest star system to Earth, which is α Centauri (South Gate 2, a triple star) that is only 4.22 light-years away from Earth.

According to observations, there is a living planet in the constellation α Centauri, which is about the same mass as Earth, and that planet is the target that humans are preparing to go to.

But just fifteen minutes ago, α star C, or Proxima Centauri, suddenly disappeared. So far, neither optical telescopes nor radio telescopes have found the suddenly disappeared Proxima Centauri.

So astronomers believe that the α Centauri is no longer safe, and it is necessary to choose the evacuated planet again. Li Ni replied.

Shan Yufeng was confused, what Centauri α star and what Proxima Centauri he didn't understand at all.

The only thing he understood was that Proxima Centauri suddenly disappeared, this was not a meteorite, but a planet, how could it be said that it would disappear. If it weren't for the big problem over there, a planet would disappear for no reason, and that wouldn't be a joke.

Soon, Shan Yufeng came to Zhongnanhai, and Li Ni took him into the Purple Light Pavilion.

Along the way, he didn't encounter any body searches, and entered the conference hall of the Purple Light Pavilion very smoothly.

"Mr. Shan is here, then our meeting will begin. ”

Seeing Shan Yufeng walk into the conference room, the three elders who presided over the meeting spoke.

Shan Yufeng smiled and nodded towards the elders, which was considered to have been said hello.

"Academician Zhang, can you introduce the current situation. ”

A man in a white coat who looked to be in his thirties stood up, did not look at the documents in his hand, and said directly: "Hello chiefs, it is not yet certain what kind of astronomical phenomenon caused the disappearance of Proxima Centauri.

However, after analysis, the influence of extreme objects such as black holes and supernova explosions has been ruled out, and at present, the most likely scenario is that Proxima Centauri entered the wormhole, so we have lost its trace.

But whatever the reason, since this has already happened, it is no longer safe around the α Centauri. Without fully figuring out what exactly is going on there, we chose a few other star systems that are closest to Earth.

Barnard is 6.0 light-years from Earth, Woolf 359 is 7.7 light-years from Earth, Brand-2147 is 8.2 light-years from Earth, UV Cetus is 8.4 light-years from Earth, and Sirius is 8.7 light-years from Earth.

These galaxies are the ones that can be reached with our current level of technology. No matter how far away the star system is, with the mass of the spaceship we build, there is a good chance that there will be problems on the way, and in fact, the distance of 8 light years is already the farthest distance that a spaceship can theoretically sail. ”

"Let's introduce information about a few star systems, and tell me the advantages and disadvantages. The Great Elder took a deep breath and said in a deep voice.

"Yes, Chief. Academician Zhang picked up the materials on the table and began to introduce the situation of several star systems.

"Barnard Star is a red dwarf star with a spectral classification of M4V, a surface temperature of about 3000 K, and an apparent magnitude of 9.6...... It is recommended because there are two planets and an unknown number of planets and moons around it, and there is a high probability that one of them is a terrestrial planet suitable for human modification.

Since it is approaching the solar system at a speed of 106.8 kilometers per second, if it is chosen as its destination, we will travel a third less time in space. ”

"Woolf 359 is a true star with a spectral classification of ...... It is recommended because it is a very stable star system, and there are three planets explored inside, one of which has an orbit similar to that of the Earth, but it is uncertain whether the planet has water resources. But this star system is 7.7 light-years away, which is exactly the limit of the spacecraft's travel distance, and it is less risky to use it as a destination. ”

"Brande 2147 Star ......"

The situation of one star system after another, with the introduction of Academician Zhang, has become familiar to everyone.

They didn't understand the technical data, but the final summary allowed everyone to understand the advantages and disadvantages of this star system.

Shan Yufeng shook his head from time to time as he listened to the introduction of these star systems.

After talking for a long time, there was no definite information, all of which were words such as probable, probable, and should. There is no guarantee that the star system has a planet suitable for human habitation, so people can make a choice, and the hope of winning the lottery is slimmer than buying a lottery ticket, it is completely a stroke of luck.

At this time, there was a sudden knock on the door, and it was very urgent, as if there was something urgent.

"Please come in. ”

As the Great Elder's words fell, the door to the conference hall opened, and Li Ni walked in.

"Chief, there is a major discovery in the space center, this is the picture taken by the optical telescope just now, and there is a very special situation in it. Li Ni took out a USB flash drive and said.

"Playback, play directly with holograms, everyone watch together. ”

In less than a minute, a hologram appeared in mid-air in the conference hall, along with a photograph taken by an optical telescope just now.

"Chief, the planet with the white glow in this picture is Proxima Centauri, which just disappeared, but five minutes ago, it came out again, and it can be calculated that by this time it has deviated from its orbit and crashed into another planet. Li Ni began to explain as the photo was displayed.

Shan Yufeng also raised his head and looked at the white light Proxima Centauri in the photo. As for whether it was heading for another planet, he didn't know at all.

The main thing is that the footage taken by the astronomical telescope is too blurry.

He also admires those astronomers who can find out which one is Proxima Centauri in this almost mosaic photo.

"This is a picture of a minute later, Proxima Centauri is getting closer to another planet, the magnetic fields of the two planets are beginning to collide, gravitational tides are sweeping over the two planets, and the golden-red light on the photo is the effect of the collision of a broken volcanic eruption and a super-large-scale high-speed particle flow.

And the inconspicuous green dot is the really special thing in it, please put down a photo. Li Ni continued.

"What is this?"

"Impossible......"

After Shan Yufeng saw the newly displayed photo, he was also confused.

A tree, a super big tree to be exact.

"That's right, after computer analysis and background clarification, this green dot is a tree. The height of the tree was calculated to be more than 57,000 kilometers. And as time goes on, even if it flies away from the planet, there is no sign that it is going to wither. Li Ni's voice trembled slightly.

In the next few photos, the image of the tree becomes clearer and clearer, and a continent is connected underneath the tree.

It's not a meteorite, it's a continent, it's the continental plate of the planet that is about to be hit by Proxima Centauri, and is separated from the planet because of gravitational tides.

And, as it flew away from that planet, it flew away from the gravitational pull of the two planets with that continental plate and headed towards α Centauri A, reaching an astonishing speed of 120,000 kilometers per second, more than one-third the speed of light. ”

At this moment, the entire conference room was silent, and everyone looked at the big tree in the photo with a confused expression.
