Deep Space Planet Leader

In the dead of night, the two youngsters were frantically writing questions.

Li Zhendong is very angry, really angry, every time he is surpassed by Zhang Yuan, he has to work hard again to surpass the opponent.

Working hard is a very painful thing for him.

Especially, this guy is doing the junior high school Mathematical Olympiad questions while laughing zi zi smirkly, what is this?

Doing junior high school mathematics questions can still be happy like Divine Immortal, is this a human?

Grabbing a handful of hair, Li Zhendong felt irritable. The various texts in the book were like fleas, jumping east and west. After watching for a long time, he didn't know what he was talking about.

I can't calm down and don't look at it.

I glanced at Zhang Yuan’s title again: "Prove: 2 open to the power of n are irrational numbers. (n is a positive integer greater than or equal to 2.)"

"Proof: Assuming that 2 to the nth power is a rational number, it is counted as pq, and p and q are mutually prime numbers."

"Then 2=(p^n)(q^n), that is, 2(q^n) =(p^n)"

& lt;p>"Move the term to get p^n=q^n+q^n."

"From Fermat’s last law: the The equation does not have a positive integer solution. So it is wrong to assume that the 2nd and nth powers are irrational numbers."

Li Zhendong almost vomited a mouthful of blood: "You can't teach me younger sister like this, really can't! You are helping her with Mathematical Olympiad questions, how can this work?"

Zhang Yuan was stunned, and found that he seemed unconsciously a free homeworker.

But it’s okay, the whole proof idea...If you copy them exactly, the teacher will definitely laugh crazy.

"Forget it, I won't do it. Pastime is enough here." Zhang Yuan yawned, feeling very happy.

Li Zhendong finally sighed in relief. He couldn't wait to put down the book in his hand and rubbed his aching temples.

He picked up the Telescope and walked out of the balcony, looking towards a direction in deep space.

Gliese 581, a red dwarf star about 2 degrees north of Beta Libra, their destination.

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

The sight of +10.56 means that the ordinary astronomical Telescope cannot see there, but Li Zhendong is still searching tirelessly.

That is the mother star of the future!

Li Zhendong suddenly have a thought: "You said, why is there a deep space project? Is it because the human top has already learned that aliens will come to attack Earth?"

"impossible !"

Zhang Yuan lightly responded: "If this is the case, it is definitely a large-scale spaceship built by the global power. And it is the turn of us to escape? You should have seen various science fiction movies, right? , The end of the world is coming, how much does the ticket for Noah’s Ark cost? Even if we are the sons of scientists, it may not be so important, right?"

"Although the movie is not real, it is also a partial portrayal of the truth. Now there is no country leader rushing to run away. When has mankind been so noble?"

There was silence for a while.

The 500,000 volunteers are not the best people in Earth civilization. Everything depends on personal volunteers. There are a few scientific giants with dreams, but the real political giants are impossible to abandon everything on Earth and go to the barren mountains and unruly rivers.

Li Zhendong laughed: "Yes, so no aliens attacked Earth. Then what do you say is the reason?"

Zhang Yuan pointed to the sky in two directions, frowns said "It may be that, it may be this...or both of them, or more importantly, the reason we don’t know..."

The direction of Zhang Yuan’s finger has a A star, KIC-8462852, commonly known as Tabby star.

The star in the other direction is Eta Carinae.

Look up and looked towards the sky.

There are few stars in the moon, and the lights in the big city obscured the bright starry sky above. It becomes even more difficult to find these stars.

In 1977 in history, there was a blackout in North America.

In the night when the lights disappeared, the boundless sky revealed its original primordial appearance.

The ridiculous scene happened. That night, the police station received many calls to the police, saying, "There are aliens attacking Earth!"

The reason is nothing more than... …These urbanites have never seen the real galaxy, they are scared not knowing what to do by the power of the ancient Great Desolate.

Yes, the Earth mother is really too warm, too gentle, gentle to the human beings of that era, and yet to be reluctant to leave the baby, has gradually forgotten the vast world outside.

But...

This World is not just humans.

The universe will not be directly disappeared because humans cover one's ears whilst stealing a bell.

The first challenge comes from the "Star Eta Carina", also known as Haishan II, an extremely supergiant star that has more than one hundred times the mass of the sun. Scientists estimate that this star may explode within a million years and form a very supernova!

Attention, it is a supernova, which has one more "polar" word than an ordinary supernova.

If Eta Carinae is 7500 light-years away from the solar system is pretty good news, then another news is simply fatal...

After research, Its rotation axis is likely to be aligned with the solar system, which is no different from a stellar cannon that is always ready to be launched!

When Eta Carinae explodes, a powerful gamma-ray burst will sweep the entire solar system.

"Unfortunately, this bright star is not visible in the northern hemisphere."

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

Even more how, scientists are still arguing about the rotation axis deflection of eta carinae and disaster prevention...

Not many, it is difficult to accurately predict the disasters it will bring to human civilization.

After a long-distance rush, the gamma-ray burst may destroy the entire ecosystem, but it may not have much impact. I can't figure it out anyway.

The second challenge comes from KIC8462852, Tabby Star.

In the 21st century, humans have discovered this strange star, and its periodic light changes have attracted the attention of astronomers.

At that time, many scientists speculated that the star was covered by a nebula or other large celestial body, which triggered its light change.

But!

Hundreds of years of observations have only proved one thing: its shading is increasing at a rate of 0.64 per thousand per ten years.

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

What does it mean?

means that there is an artificial structure near that star, and it is under construction at a constant speed.

It has been going on for hundreds of years!

Dyson Ball, it's there. There will be no changes due to human will.

This fact caused a huge panic among the high-level civilizations.

The distance of 1400 light-years is too far for mankind, but it is far from enough to smooth this panic.

Any normal person knows what "Dyson Ball" means.

Human civilization, compared with the civilization that can build Dyson spheres, is simply a paramecium!

At that time, Professor Qi Yuanshan, the "father of nuclear fusion", wrote in his diary excitedly: "If there are no aliens, mankind will be destroyed by its own laziness!"

"...Just like in the old days, the upcoming entertainment trend, non-toxic neurological drugs will destroy most of the enterprising spirit of mankind. The Dyson ball is proved to be true, and mankind may be able to recover from corrupt consumerism and capitalism. Cheer up, similar to the effect of the Cold War between the United States and the Soviet Union!"

"I have to say that mankind has a good neighbor, and there may be hope. Fortunately...!"
