In fact, after solving the mystery of the disappearance of the third group of migrant trains.

Biosphere shifted course, changed direction, and headed straight for a blue dwarf 18 light-years away.

In order to arrive as soon as possible, the Ecosphere underwent another round of acceleration, reaching an astonishing 0.8C.

At this speed, the time dilation coefficient is 25/9, i.e., 25 years have passed in the stationary case and 9 years have passed in the spacecraft.

Therefore, the time signaling system of the ecosphere number will prompt once every 24 hours:

"Dear Biosphere passengers, there are 8 years and 23 days left to reach α Lyra."

"Dear Ecosphere passengers, there are 8 years and 22 days left to reach the α of Lyra."

"Respect ......"

I do this every morning.

I was washed by this countdown for a while.

Some people began to wonder, who is α Lyra, the star in the starry sky?

After searching in the Wandu search, I immediately found the relevant information.

It turned out to be Vega.

In astronomy, it is also known as "Vega" and "Vega", which is 25 light-years away from the solar system, and the night sky on the side of the blue star ranks fifth brightest, and is the second brightest star in the Northern Hemisphere, after Arcturus. Along with Arcturus and Sirius, it is one of the brightest stars near the Sun.

In addition, it forms a summer triangle together with "Cowherd Star" and "Tianjin Four".

It is a star that astronomers on the Blue Star side often observe and study.

At this moment, the ecosphere number is heading straight for Vega.

There are more than eight years left.

There was a heated discussion on the Internet.

Anyway, what is the Ecosphere going to do on Vega?

"Do you want to replenish some supplies near Vega?" Some netizens said.

"No, as a blue dwarf star twice the mass of the Sun, the strong radiation pressure and stellar winds released by Vega will disperse the nearby dust clouds, and it will be almost impossible to form planets, and it will be difficult for us to gather supplies." Another netizen said.

"That'...... Just stopping by and doing a little bit of a science experiment to study blue dwarfs? ”

"Hehe, this is not called a journey, but a deliberate 3-light-year detour, just to study the blue dwarf, it is not worth wasting more than a year of travel time for this, if there is no great value and benefits, no one will deliberately detour this long distance."

"Could it be...... Just, like Neptune? ”

This netizen had a flash of inspiration in his mind, and immediately showed a shocked expression and stammered: "This, how can this be, twice the mass of the sun, equivalent to 2,000 Jupiters and 37,000 Neptunes, so how, how can you eat it?" ”

"It only took ten days to eat Neptune, and with that exponential devouring rate, I estimate that Vega will only take ten days at most."

"That's a star!"

The netizen shook his head: "I can't imagine that it will be destroyed so easily, its surface temperature is 8,000 degrees, its core temperature is more than 20 million degrees, and there are 1.5 billion years of combustion life, all of this will end in ten days?" I—I can't imagine. ”

"Please enjoy it when the time comes, it will definitely help you a lot to enhance your imagination."

The wisdom of the masses cannot be underestimated.

The purpose of the ecosphere to go to Vega was quickly speculated and analyzed by netizens, and a consensus was gradually reached: Vega, which originally had a lifespan of 1.5 billion years, may only have eight years left to live.

In the near future.

Some textbooks of human civilization, some myths and legends that have been passed down for thousands of years, such as "The Cowherd and the Weaver Girl", etc., I am afraid that we will lose the reference comparison, and the Cowherd Star in the starry sky, not to mention the meeting of the Magpie Bridge, I am afraid that I will be reduced to a single dog.

The "summer triangle", which is often observed by astronomy enthusiasts, has become a "summer line" and so on.

It will bring inconvenience in many fields, and even make the children born later feel full of doubts, where did the "Weaver Girl" in "The Cowherd and the Weaver Girl" go, and the triangle of the "Summer Triangle"?

There are so many beautiful myths and legends, whether they are made up or not, how can there be no comparison at all in reality, and the sense of substitution has suddenly dropped by more than one level.

And so on and so forth.

That's because of this.

Some groups of Chinese teachers and astronomy enthusiasts in the Ecosphere launched a campaign to "save Vega", or held a petition with millions of signatures, or held slogans and took to the streets in the hope of attracting attention.

"Please spare Vega."

"Find another star instead, Vega is an important cultural heritage, don't destroy our culture."

"If we didn't have Vega, we would be very troubled, and the children would be confused."

"Boss, listen to our appeal, adjust the current plan, and change to another goal."

As the opposition grows louder.

In the online voting, the proportion of people in favor of changing the target was as high as 70%.

Wei Ming felt quite annoyed!

In the face of pressure, he had to come forward and say: "There will be no change in the existing plan, stop talking about this topic." ”

"The current education system has fully promoted the virtual classroom system, and children can see Vega in the virtual classroom without any impact!"

"The weather system inside the Ecosphere, after setting it to the summer starry sky, can see the 'Summer Triangle' every day, and it doesn't have any impact."

"Culture is just a kind of information after all, and it doesn't necessarily need an actual carrier, as long as the brain turns around and is not bound by the framework of reality, we can create a lot of excellent culture...... That's the end of it! Don't be rigid and stubborn, the true value of Vega, as you will soon see, is much higher than the value of being a cultural carrier. ”

After adding the propaganda and popularization of science by a group of scientists.

The "Save Vega" activity finally slowly stopped.

The delicate Chinese teachers who took to the streets gradually paid attention to the establishment of the "Vega Museum", so that Vega could exist in another form.

"Dad, why don't you let Vega go."

On this day, Wei Nuan, as the director of the Vega Museum, had red eyes, as if she had just cried, and came to Wei Ming and said: "Vega is so pitiful, all the members of the museum are crying today, Vega has a soul and has been given a soul by us, but I didn't expect that when she was not dead, we began to erect a monument for her and build a museum, which is really pitiful." ”

"Woo~"

As she spoke, she couldn't help but shed tears again.

Wei Ming's head was full of black lines.

Needless to say, it must be those women who have eaten too much, have nothing to do, and are full of emotion, and even their daughter Wei Nuan has been affected.

Vega is just an ordinary big ball of fire, what are you moved by by the stories in your mind, are you worried that it will affect the Qixi Festival to receive gifts?

It's just speechless.

However, Wei Ming didn't want to complain to his little daughter, so he comforted him, and finally said: "Since the museum has been built and the tears have flowed, but Vega is still there, isn't the museum built in vain, and the tears are in vain, doesn't it mean that everything is in vain?" Isn't it nonsense that the hero has already died, and the last few minutes suddenly brought the hero back to life? ”

"Uh, yes, I guess."

Wei Nuan nodded confusedly, feeling that it made sense.
