Half-immortal civilization

Electromagnetic waves are sent out from the stars one after another, flying to the distant solar system!

At this time, all the empires on the Celestial Star have gathered together to discuss and study what kind of thing this is, which seems to be very advanced.In particular, what interests everyone the most is the precise positioning system and the powerful energy that is still powerful after crossing long distances!
At this moment, on Venus, it has already reached the 46th year of the Imperial Calendar, but the Empire is a little nervous now, and a huge challenge to the survival of the entire human race is about to come!

Supernova Remnant!
As early as a hundred years ago, some scientists had estimated that the solar system would enter a supernova remnant range; according to the current detection, there are still 18 imperial years, and this unprecedented test is coming.At that time, even the sun will be tested... A supernova remnant covers a light-year range, and the outermost temperature is more than 160 K (k is the absolute temperature, about minus 110 degrees), which is only 3- Among the cosmic background temperature of 6K, the absolute degree is high temperature!
And this is just the periphery. In the next thousand years, the solar system will spend in this supernova remnant.Therefore, in the face of this test, the empire has nothing to do!a!Let God decide!
In the Imperial Academy of Sciences in space, all the astronomers, cosmologists, high-energy physics and other elites from the earth, Venus and the entire human race gathered together!
When people on earth bring disasters to others, they themselves are about to meet the challenge from the universe!

Hundreds of probes are circling around the outer reaches of the solar system and within the Oort cloud; in addition to receiving probe signals from all directions in the universe, they also want to detect the space around the solar system.

Now, the detected data is worrying.Exploration continued for more than 10 imperial years, and the supernova remnant is still not very clear.But now, under the influence of supernova remnants, the solar system's heliosheath has begun to fluctuate far more than ever before. It is a confrontation between gravitational forces.An obvious high-temperature ion belt appears in front of the heliosheath, with a height of 300 billion kilometers, a thickness of 20 billion kilometers, and a length of more than 2700 billion kilometers! ! !The leather shell that wraps half of the solar system in the direction of progress!
According to existing observations.The solar wind is affected by the gravity of the sun, and it is difficult to fly out of the solar system; these charged particles will continue to accumulate, and finally form an invisible crust.Some people call this the sun shell, and it is at the top of this shell.It's what scientists call a heliosheath.The heliosheath has a natural anti-radiation ability, and is also an alternative protective layer. Some star rays, etc., will be filtered out a lot.

Of course, the solar crust also has another function. It is affected by the rotation and gravity of the solar system. Its thickest place is on the same plane as the orbit of the planets, which forms a different kind of prism—for example, sometimes, only The bright stars can only be seen in the orbit of the planet or around a certain range; but if you leave the range of the orbital plane, you may not be able to see the stars in space, etc.This shell effect once caused panic in the earth science community - thinking that the earth is a virtual world!But now it has been unraveled, and a probe has been launched in the universe.It is necessary to calculate the light distortion and influence caused by the leather shell.

But the problem now is: the solar system's shell is absolutely unable to stop the supernova wreckage - compared to this wreckage that covers at least one light-year range, the small solar system is really powerless.It's like putting a tightly wrapped egg into boiling water, no matter how well prepared you are, as long as you persist for a while, it will always be cooked!This is the current situation in the solar system-how can a small leather shell compare to the wreckage left by a whole explosion!At that time, it will be like a sandcastle under the stormy sea.As soon as you rush, you will be scattered!
Didi... Didi... In the Academy of Space Sciences, there is no idle moment. Since the establishment, it has immediately entered into non-stop research.This 150-kilometer-long object looks like an artificial continent from space!Maybe the technical content is not as demanding as the spacecraft, but it should not be underestimated!now.There are more than 30 people living here, and here, except for the few students, all of them are truly top scientists-in fact, even those students are also top students!If this place is taken over, human scientific research capabilities will definitely go back 20 years!
Randomly release a scientist here.All enough to build a high-tech business!

"Your Majesty, there is not enough information to make effective calculations!" Chen Feng's face turned pale. In order to calculate the impact of this supernova remnant on the solar system, he has been stationed in space for two consecutive years.If it weren't for Zhang Wenliang's forced order to rest for several months, maybe even if he is practicing, his body would have collapsed now.

"Whether it is sufficient or not, you now tell me about your research. Don't forget, the solar system is entering a supernova remnant, and every citizen knows it; now, everyone is waiting for your research report! Even if it is fake Okay!"

Zhang Wenliang rubbed his temples vigorously, the emperor's seat is not easy to sit on; and it is even more so now!The entire solar system is about to enter the supernova remnant, and the public is now inexplicably panicking—can the supernova remnant melt steel?
Especially now, because of the highly developed technology of Venus and the openness of the society, people on Earth are directly getting rid of the government, sending electricity to ask the Imperial Advisory Group: How should we do it?Therefore, the pressure on Zhang Wenliang's shoulders is actually very great: the tens of billions of people in human civilization are on his shoulders!
"Your Majesty, although the data is insufficient, the calculated results are not bad. It is more in line with previous conjectures, that is, the temperature of the interstellar space in the solar system will rise to about 20 degrees. At that time, even the moon, Mars, Europa , Pluto and other planets are suitable for habitation in terms of temperature. What is about to usher in mankind is not a disaster, but a fortune!

Moreover, this increase in temperature will not have any impact on the sun itself. There are temperature fluctuations of several thousand degrees on the surface of the sun, and temperature changes of more than 200 degrees have little effect.However, the earth and Venus must be prepared to block more sunlight, otherwise, under the high temperature and sunlight, our temperature may exceed 50 degrees.

The reason for this phenomenon is that in addition to the temperature of the supernova remnant itself, there is also the fact that after the collision, the light and heat of the solar system itself cannot be emitted, which will cause a galaxy-wide greenhouse effect.But it's about 20 degrees.will stabilize on average.

We have calculated it many times, and the result is the same every time. "

"Professor Chen, does this mean that human beings will be able to emigrate in the solar system?" Zhang Wenliang's eyes lit up.

"No, Your Majesty. Among the current planets in the solar system, except for Venus and the Earth, the gravity of the rest is not enough, even less than half of the minimum standard. Under such an environment, it is fine for a short time, but for more than three years, human beings It will become waste. For example, bone loosening, blood vessel expansion, internal organ degeneration, etc. Moreover, according to current research on life sciences, human beings can gradually adapt to a greater gravity environment; but they cannot gradually adapt to a smaller gravity environment, otherwise human beings It's going to take a very tragic turn."

"Hey. So, it seems that interstellar immigration is still the way to go."

Information from space is constantly being aggregated, and calculations are becoming more and more precise.But all the results show that, apart from the strong radiation, there will be no impact on the solar system.It turned out to be good! ! !At that time, the cold Pluto will become a mining site for humans!You must know that over the years, the development of Venus has created a situation of unlimited demand for your mineral resources.Interstellar era.It is the pinnacle stage of a steel civilization!At this time, human's demand for steel and any metal can no longer be expressed in numbers!

Just to build a spaceship would require blowing up a 3600-kilometer-diameter planet for mining—not to mention breaking it into pieces, and dragging it back to Venus to shatter its ashes.And the current empire can only be regarded as touching the edge of interstellar civilization.Based on this inference, it is conceivable.When it really enters the interstellar civilization, only the mineral resources stored in the solar system itself cannot meet the needs of such a civilization at all!
Suddenly, Zhang Wenliang thought of the Zerg in interstellar-themed movies or games: eat wherever you go, even the planets!Why is this so much like human beings themselves!

The definition given to viruses by humans at the beginning.In the end, it was found that the most suitable one turned out to be human beings themselves!

But now Zhang Wenliang suddenly discovered that the most suitable definition of human beings for the imaginary Zerg is still human beings themselves!
Shaking his head violently, Zhang Wenliang threw this unrealistic idea out of his mind. If he continues to think like this, he will be thrown tomatoes!
Thinking about it, Zhang Wenliang suddenly thought of interstellar immigration, "Professor Chen, do you think this time the supernova wreckage will affect this interstellar immigration?"

"Ah..." Chen Feng suddenly froze!Yes, among the interstellar immigrants, Chen Feng also held a certain position in this technology team, so of course he knows something about it; but in recent years, Chen Feng has focused his energy on the supernova wreckage, so that the relationship between these two things The relationship between them is neglected; in other words, everyone is busy in their respective fields, and ignores others intentionally or unintentionally.

But now that Zhang Wenliang suddenly pointed it out, Chen Feng was suddenly stunned.Yes, does this change affect the first interstellar immigration of human beings?

This is definitely a big deal.Whether it is the civil society, the scientific community or the ruling class, this immigration has strictly required a 100% success rate!If it succeeds, it will have a profound impact on the future interstellar expansion of the empire.And if it fails—hehe, not to mention anything else, about 2000 million lives would be enough for Zhang Wenliang to commit suicide to thank the world.Not to mention the confidence in the empire's interstellar immigration after failure.

It can be said that this time is not just a simple immigration, but also a threshold!An empire has entered the threshold of interstellar civilization from space civilization!The consequences of failure cannot be borne by the current empire!To be precise, that responsibility is not something that can be appeased by launching a scapegoat. The national quintessence of the entire empire for more than 40 years may be shaken.

"I'll go and research!" Chen Feng was serious, and he didn't give the answer right away.This is the attitude of science, not the kind of expert, just opening his mouth: I think...

For seven consecutive days, I changed more than [-] item every day for seven consecutive days.There will be one more later.
