Doomsday Fast Travel: Kill That Black Butterfly

Yu Di didn't know that in Gu Fu's heart, she had equated with autistic children.She is discussing with Du Meng how to make Galu star avoid the scorching sun.

The star (let's call it the sun) in the galaxy where Galus is located had already begun to devour the planets around it as early as 670 million years ago.With further expansion, it has begun to significantly affect the ecological environment of Galus, and the global temperature is rising by about 0.1 degrees every year.Scientists conservatively estimate that in about 800 years or so, the liquid planet Galu Star will begin to evaporate.

It sounds like there is still a long time to go, but like boiling a frog in warm water, this is an ongoing process.As the temperature of Galu star continues to rise, marine life will gradually become extinct because it cannot adapt to the high temperature environment.Most creatures on this planet rely on liquid stone to live. As mentioned earlier, the evaporation point of liquid stone is very high, so they can't wait for 800 years at all.

Du Meng is clearly aware of this.

In the post-interstellar era, it's not that Ulu didn't think about migrating to other planets, but they didn't find a suitable planet within their capabilities.As mentioned earlier, liquid stone is a very rare liquid material, and Galu star is the largest aggregate.

People from other civilizations once suggested that they build a spaceship and fly wherever they want, which is better than staying on Galu and waiting to die.At that time, the Ulu government also launched a referendum, and finally rejected the proposal with an overwhelming number of votes.Most Uru people are unwilling to abandon their hometown, and a small number of Uru people have a great fear of interstellar travel.

Because the first batch of Ulus who traveled to the stars with the help of alien civilizations returned with a large degree of genetic damage to their bodies, suffered from illnesses, and died miserably.In order to prevent the public from panicking about alien civilizations, the government tries to keep the news of these astronauts in a very small circle as much as possible, and dare not spread it to the outside world.Most of those who know the truth are Ulu from the Academy of Sciences.

Under the circumstances that both elites and civilians resisted, the Ulu government naturally no longer thought about this thankless spaceship project.

Even if Ulu's lifespan is twice as long as that of humans, and the limit is about 260 years, things after more than 800 years are still relatively far away for them.So the Uru simply began to lie flat, enjoying the solitude of being the last higher life in this universe.

It is amazing that since accepting the result that one's own civilization will die, the crime rate in Ulu society has dropped greatly.The originally expected chaos did not happen, but the Ulus began to return to their families and cherish their present.

The birth rate remained at a relatively low level, as expected.

Yu Di also thinks that this situation is not easy to handle, because with Ulu's current technological level, it is impossible to build a reflective layer outside Jialu Planet to isolate the sun's heat.And even if a reflective layer is built, it can only be delayed for a while.

According to Dumeng's calculations, the expansion limit of the sun is just enough to completely engulf Galus, and no material can maintain its original properties within the expansion range of the star.And after devouring Galu Star, the sun will begin to collapse.Compared with the expansion, this process can be completed almost instantaneously. In the blink of an eye, the sun that has expanded to the limit will become a neutron star or a black hole.

Du Meng had no idea how Jialu Xing could escape this catastrophe.

For Yu Di, the information packet this time is really embarrassing for her.Although the information package contains the scientific and technological achievements of all civilizations, knowledge is not something that can be poured into the brain.To find a suitable method, Yu Di must learn and understand these knowledge.

This knowledge belongs to different races, civilizations, and even galaxies are separated by hundreds of thousands of miles.The Uru technology tree of Planet Jialu is already amazing enough, and in the information package, there are even more outrageous alien civilizations.What silicon-based organisms, photonic life forms, giant insect nests.Facing various technology trees far away in the sea of ​​consciousness, Yu Di covered her face in pain.

She is not a translator, how can she convey these words that she doesn't even understand!

Leaving the sea of ​​consciousness and talking to Du Meng has even become a kind of relaxation.

Dumeng was surprised by Yudi's insistence on continuing the Ulu civilization, so he simply put forward an idea that had been buried in his heart for a long time.

"You want to build a spaceship and leave Galu with the gene pool?"

Du Meng blinked his four big eyes and said: "Uru's physiological structure is destined to survive in an environment similar to that of Galu. But genetic information is not. Our recording method is the longest time in this universe. Long ago, maybe one day, this record will be discovered by the newly born Kaluwai civilization."

Yu Di twitched the corner of her mouth: "Isn't this a stroke of luck!"

Dumeng waved the frontmost tentacle: "No. There is actually a Gallo-like planet 930 light-years away from us. It’s too small, only one-tenth the size of Jialu Planet, so it can’t accommodate us. In addition, Uru’s physique can’t adapt to interstellar travel, so we gave up this place.”

"So you mean to send the data with the information of Jialu's existing species to the second planet of Jialu?"

"Correct."

"Then how do you ensure that the spaceship will be able to travel to the second star of Galu? 930 light years, let alone our spaceship can't reach that speed, even if it can reach it, it will take four generations."

Du Meng looked at Yu Di strangely: "Interstellar travel is all about jumps, who would really fly for so long?"

Yu Di was at a loss for words for a while: "Since it's a leap, why don't you just draw immigration qualifications and move there little by little?"

This is how the dungeons of the last world worked.

"Didn't I say that Ulu's physique is not suitable for interstellar travel? When I say unsuitable, I mean the leap."

"Oh... so what are you going to do?"

"I didn't plan to let Ulu drive the ship at all. There are no very large celestial bodies between our place and the Galu II star. If the calculation is accurate, the defense module that comes with the spacecraft is enough to deal with some small disturbances."

Yu Di tilted her head and thought carefully.I have to say that Dumeng's idea is indeed very constructive.Spaceship technology has been accumulated during previous exchanges with alien cultures.And Ulu's vibration technology is the top in the universe, used in the defense module, it can almost completely dispel material damage without damage.

The only problem with this solution is navigation.

Or rather, route planning.

The interaction between various celestial bodies in the universe is quite complicated.Even a short-distance spacecraft will face various changes at any time, let alone a journey that will last for thousands of years.If there is no intelligent creature with a high enough level to control it, once there is a slight error in any part of the calculation, it will lead to the failure of the plan.

Unfortunately, Uru's AI is a weak point.

But for Yu Di, as long as he has an idea, technology, etc., he can learn it now.She closed her eyes and sank into the sea of ​​consciousness, found the technology trees of several silicon-based biological planets, and began to read.

After all, silicon-based organisms only have 01 machine language, so even if Yu Di can't understand it, he can still draw pictures for Ulu.

Change it!
