Deep Space Fleet

When the night was quiet, the two young men were crazy about the problem.

振 Li Zhendong is very angry, really angry. Every time he is surpassed by Zhang Yuan, he has to work hard to surpass the other party.

Hard work is very painful for him.

In particular, while this guy was doing junior high school math problems, he was smirking cheerfully. What was this?

I can do junior high school math problems like a fairy. Is this human?

I scratched a hand of hair, Li Zhendong was irritable. The various texts in the book were like fleas one by one. He jumped east and west, and didn't know what he was talking about for a long time.

Quiet and uneasy, didn't watch.

I glanced at Zhang Yuan's topic again: "Verification: 2 open n powers are irrational numbers. (N is a positive integer greater than or equal to 2.)"

证明 "Proof: Assume that 2 to the nth power is a rational number, and count it as p / q, where p and q are prime numbers."

那么 "So 2 = (p ^ n) / (q ^ n), that is 2 (q ^ n) = (p ^ n)"

"The shift term is p ^ n = q ^ n + q ^ n."

"It can be obtained from Fermat's law: the equation does not have a positive integer solution. So it is wrong to assume that 2 to n powers are irrational numbers."

振 Li Zhendong almost spit out an old blood: "You ca n’t teach my sister like this, you really can't! And you are helping her with math problems, how can this be done?"

愣 Zhang Yuan stunned and found that he seemed to become a thug who did his homework for free.

But it doesn't matter, the whole proof of thought ... if the copy is exactly the same, the teacher will laugh.

"Forget it, I didn't do it either. It's enough for pastime here." Zhang Yuan yawned and felt very happy.

Li Zhendong was finally relieved, can't wait to put down the books in his hand, and rubbed his temples.

He picked up the telescope, stepped out of the balcony, and looked in one direction of deep space.

Glitzer 581, a red dwarf about 2 degrees north of Libra β star, their destination.

Its mass is 0.31 solar mass, its radius is 0.38 solar radius, and its surface temperature is about 3,480K (3206.85 ° C).

The observation star of +10.56 means that ordinary astronomical telescopes cannot see it there, but Li Zhendong is still searching tirelessly.

That is the future mother star!

Li Zhendong had a sudden thought: "Why do you say there is a deep space plan? Is it because the high-level humans have learned that aliens will come to attack the earth?"

"Impossible!"

Zhang Yuan responded lightly: "If this is the case, it will definitely be a global effort to build a large-scale spaceship. And it ’s our turn to flee? You should have seen all kinds of science fiction movies. The end of the world, Noah's Ark ’s How much does a ferry ticket cost? Even if we are the sons of scientists, it might not be that important? "

"Although the movie is not real, it is also a portrayal of the real thing. No country leader is in a hurry to run now. When is humanity so noble?"

I was silent for a while.

The 500,000 volunteers are not the best people in the earth's civilization, and everything depends on personal volunteering. There are a few scientific giants with dreams, but the real big names in politics cannot give up everything on earth and go to the kind of poor mountains and rivers.

振 Li Zhendong smiled: "Also, so there are no aliens attacking the earth. What do you say?"

Zhang Yuan pointed at the two directions of the sky and frowned: "Maybe that or this ... or both, or there are more important reasons that we don't know ..."

In the direction of Zhang Yuan's finger, there is a star, KIC-8462852, commonly known as Taby Star.

一颗 The one in the other direction is the η star at the base of the ship.

I looked up at the sky.

The moon is rare, and the lights in the big city have blocked the bright starry sky above you. It becomes more difficult to discover these stars.

In 1977, there was a blackout in North America.

那个 On the night when the light faded, the boundless sky revealed its original appearance.

A ridiculous scene happened. That night, the police station received a lot of alarm calls, saying "There are aliens attacking the earth!"

The reason is nothing more than ... this group of urban people have never seen the real Milky Way, they are overwhelmed by the power of ancient floods.

Yeah, Mother Earth is too warm, too gentle, human beings who were gentle to that era, have been reluctant to leave 襁褓, and have gradually forgotten the vast world outside.

But ...

This world is not just human.

The universe does not disappear because of human beings covering up their ears.

The first challenge comes from the "star η", also called Haishan II, an extremely superstar, which has more than 100 times the mass of the sun. Scientists estimate that this star may erupt within a million years, forming a supernova!

Note that it is a supernova, which has one more "polar" character than an ordinary supernova.

If the η star of the ship's base, which is a full 7,500 light years away from the solar system, is good news, then the other news is simply fatal ...

After research, its rotation axis is likely to be aligned with the solar system, which is no different than a star cannon ready to be launched!

When the η star of the ship's base explodes, a violent gamma-ray burst will sweep the entire solar system.

"Sorry, this bright star cannot be seen in the northern hemisphere."

Of course, this disaster may be large or small. First of all, the time of its outbreak is too vague, it may be a million years later, it may be tomorrow, or even a hundred years ago.

What's more, scientists are still arguing about the rotation of the rotation axis of the ship's η star and disaster prevention ...

Humans don't know much about this kind of celestial body, and it is difficult to accurately predict the disaster it brings to human civilization.

After a long-distance running through a gamma-ray burst, the entire ecosystem may be destroyed without much impact. Anyway, not sure.

The second challenge comes from KIC8462852, Taby Star.

21st century ~ www.readwn.com ~ This strange star has been discovered by human beings, and its periodic light changes have attracted wide attention of astronomers.

At that time, many scientists speculated that it was the nebula or other large celestial bodies that covered the star before triggering its light changes.

But!

数百 Hundreds of years of observation only prove one thing: its shading is increasing at a rate of 0.64 per thousand per decade.

That is, if the maximum shading data of ten years ago was 22.112% shading, then it is now 22.176% without exception.

What does holding mean?

Means that there is an artificial building near the star, and it is being constructed at a constant speed.

Has been going on for hundreds of years!

Dyson Ball, it's there. No change will occur because of human will.

This fact has caused great panic among high-level civilizations.

The distance of 1400 light years is too far away for human beings, but it is far from enough to smooth out this panic.

Any normal person knows what "Dyson Ball" means.

Human civilization, compared with the civilization capable of building Dyson balls, is simply a paramecium!

At that time, Professor Qi Yuanshan, the “father of nuclear fusion”, wrote in his diary with excitement: “Without aliens, human beings will be destroyed by their own laziness!”

"... Just like in the old era, the imminent entertainment trend, non-toxic neuropharmaceuticals will destroy most of the enterprising spirit of human beings. Dyson Sphere has proven to be true, and human beings may be able to regain their strength from eroding consumerism and capitalism. The effect of the US-Soviet Cold War! "

"I have to say that human beings have a good neighbor, and maybe there is hope, but fortunately ... oh!"
