Half-immortal civilization

On the high Misty Peak, Zhang Jingyuan led his wives quietly observing the sky.At this moment, Zhang Jingyuan suddenly felt a sense of powerlessness. Under such a disaster, technology still has the absolute upper hand!If you are a practitioner, if you want to defend the entire planet, you probably need the ability of a fairy; otherwise, you need a lot of fairy stones-this thing is not a Chinese cabbage like solar energy and nuclear energy.But under the means of science and technology, people have used cold stones to make brilliant technological products, but these seemingly cold technological products have formed the strongest shield on the planet, firmly blocking the radiation on the planet. outer space.A small amount of missed radiation will also be absorbed by the magnetic levitation particles suspended in the magnetic field of Venus and the atmosphere, which are invisible to the naked eye and do not affect human health.

Zhou Feixuan and her three daughters are quietly by her side. Although they are already the mother of a country, the three daughters still abide by their duties and do not pursue luxury. Now they follow Zhang Jingyuan to retreat and practice here in Misty Peak all year round.The solar system is just so big, and it has already traveled all over the years, and now it is about practicing, seeking longevity, and even eternal life.Perhaps the only pursuit is to hope for a child to become a dragon-but don't worry, they are all dragon kings.

"Let's have another child." Zhang Jingyuan looked at the lonely Feng Xuezhi, and gently cared for her. His daughter Zhang Ting followed her husband and immigrated!Now that they are on the road of interstellar immigration, it is impossible to say that Feng Xuezhi is not worried.

"En." Feng Xuezhi didn't refuse. Although they are all over a hundred years old, their practice has kept their bodies in the peak state of 20 years old, and even their own abilities have become stronger.

One day...two days...the radiation went on for a week and then dissipated quickly.This kind of radiation is the light released after the supernova erupted; and this kind of light obviously only has one wave!It comes and goes quickly, not just having 3 minutes of passion with human beings; now that it has passed, it shows that human beings have passed the most dangerous link!The rest is pediatrics. Although those nebulae still have a certain amount of radiation, for example, they contain hydrogen tritium (tritium) and other radioactive substances.However, the unit radiation energy of this nebula is much lower than that of the sun. On the contrary, the high temperature carried by the nebula will affect the development of manpower.create a huge boost.

"I didn't expect that not only the practice needs to overcome the calamity, but even the development of science and technology also needs to overcome the calamity!" Zhang Jingyuan left such a sigh, picked up Feng Xuezhi and strode away-continue to play the game of making people... When a practitioner becomes stronger, he will unknowingly turn on certain gene fragments in his body, and under a strange mechanism, it will reduce his ability to reproduce.Now, here in Misty Peak, a professional research team has been formed, but there are still no results.According to Zhang Jingyuan's estimate.This should be a natural law or even a law of heaven and earth.

At the end of July in 63 Imperial Calendar, the front of the nebula finally covered Venus and the Earth. In an instant, the sun visor in space was activated to filter and block part of the sunlight.From interstellar temperatures.began to sweep the entire solar system.

Interstellar space temperature: generally greater than 20 degrees for the time being! ! !
The radiant cosmic space fades away and is replaced by a warm space.And this also indicates that human beings will begin an alternative development path of at least a thousand years!But for human beings, especially for this rising human world, a thousand years is precious!It is also enough to bring the development of human technology to another level!
--------

"Detect the temperature of the space behind!" In the scientific research base in space, Zhang Chengye did not relax, it was more than 20 degrees.Just the temperature at the front of the nebula, according to normal thinking, the temperature at the back will inevitably be higher; but how high it is, it needs to be strictly tested, which is related to the safety status and development mode of human beings in the future.So when the radiation passed, the scientists didn't end the fight.In fact, the protracted war has just begun!For at least the next thousand years, scientists need to fight at the forefront!

To be precise, in the development of modern human science, it is the battle of scientists; and they have never stopped fighting!It's just that now it's a battle with the sky!And it will probably continue for thousands of years, ten thousand years...

"Detection and calculation." Zhong Qingyuan didn't look up, as Zhong Yuanxing's grandson.Zhong Qingyuan inherited his grandfather's position as the Minister of Space Environment Science and Technology, and is now also the commander of this interstellar war.

"A112 area temperature is 23.34 degrees!"

"The temperature in the c345 area is 21.76 degrees!"

"The temperature in the g768 area is 24.56 degrees!"

A large amount of data is continuously returned by observation, and Zhong Qingyuan is busy directing his staff to calculate each data array.It is a more rational way to roughly evaluate the subsequent temperature changes by means of arrays.

With the convergence of data, an isotherm in the cosmic environment is finally marked!
The huge screen was ten meters long and wide, and it was covered by dense lines at the moment. In the current high-tech demonstration, the flat screen still had unique advantages.The pursuit of scientific research is function, not brilliance, so it is suitable, and the projection technology that is now very mature is not used.In fact, the current graphic technology is more delicate, which is very similar to looking at paper directly, and it is also very popular.

Today, the real nebula that can be observed is divided into 26 steps from a to z, and each step has thousands of observation points. After summarizing all these data, the isotherm of a nebula is drawn.After the isotherm is drawn, it can be clearly seen that about every billion kilometers, the temperature changes by about 0.1°, forming a gradient.

Through this isotherm, it can be seen that the nebula that is currently connected to the solar system is only the most advanced part, and there are too many behind it, and even all the telescopes cannot detect and receive the most source information. Obviously Its width is at least more than one light-year!It is not surprising that the radius of supernova remnants exceeds one light-year; in the universe, the smallest distance between two adjacent stars is 4.2 light-years—in other words, the gravitational radius of a star should actually be two light-years away!It's just that after more than 1000 billion kilometers, its impact is very small, and it can almost be ignored in a unit space.

"The average temperature at the forefront is 21.3765 degrees, and the final space temperature that can be detected is 22.0765 degrees, while the temperature at the edge of the Oort cloud in the middle is the highest, with a full 22.3876 degrees. By comparing the overall gradient, it is obvious that the temperature behind It's lowering!" Zhong Qingyuan reported meticulously to the scientists present.to be honest.Because of practice, many of the scientists present were old people from Zhang Jingyuan's time; Zhong Qingyuan can only be regarded as the grandchildren of this place, even Zhang Chengye needs to greet some old experts here respectfully.

"Huh?" An old expert looked at the data for a long time, and then looked at the data.Then he frowned and said to himself, "What caused this situation? It is said that the rear should be closer to the core of the wreckage, and its temperature should be increasing. In any case, there should be no decrease in temperature!"

"Is...is it cooling down at the back? After all, this nebula has been in existence for at least [-] years, and it is also possible for the temperature at the center to cool down. For example, through radiation heat release, ultraviolet rays gradually decay into infrared rays. And That is, maybe the temperature at the center is not low, but the radiated ultraviolet rays are blocked by the nebula itself and decay into infrared rays?" Zhong Qingyuan guessed somewhat uncertainly.

"Nonsense, the interior of the nebula is a relatively closed space, and the expansion of the nebula is from the inside to the outside. That is to say, compared with the outside, the energy density inside will be higher. In this case, what we detect must be Ultraviolet rays cannot be infrared rays. Especially the entire nebula presents a regular cooling gradient. Obviously there is a mechanism of action!" The old expert looked at Zhong Qingyuan very dissatisfied - young people these days are just unreliable!
"Is this the reason!" Beside, Chen Feng suddenly jumped up, "Look, although the nebula is huge, it looks very similar to an internal combustion engine! The internal heat expands, but the temperature is lowered by doing work! The huge internal pressure and temperature In the process of continuous expansion, the heat and temperature are transformed into radiation and power, constantly pushing the expansion of the outside.

Then because it is in space, two mechanisms may be involved.The first one is the work done by the expansion; the other is that the propagation of heat also takes time, and the expansion of the nebula is also very fast; just a coincidence, that is, the front of the nebula coincides with the radiated heat!This causes the temperature at the front to be high, but the temperature at the back is actually not high!
Well, if I'm guessing right.The temperature of the core inside the nebula may be lower than zero! "

Chen Feng is not an astronomer, but in this era, scientists are more or less in contact with astronomy.What's more, Chen Feng himself is an engineer and expert himself, with a very wide range of design knowledge; and now.This inflated nebula made Chen Feng link it with the work of the internal combustion engine in a flash.In fact, although the internal combustion engine has almost been replaced by the electric motor, in some places, the internal combustion engine is still being studied-the scientific concept is: there is no useless technology, only useless technology!For example, the steam engine, an antique technology, but after a facelift, it is one of the core equipment in almost all power generation industries in the process of generating electricity in nuclear power plants.

And it was also because he was in charge of the cutting-edge technology research of the empire, which allowed Chen Feng to get in touch with a wide range of people, and he immediately connected the expansion of luck with the way the internal combustion engine works!Not to mention, this kind of statement is really well-founded, and it is not the kind of unreasonable trouble!
"Adjust the detector and observe the space behind!" Zhang Chengye made a decisive decision!The temperature of the nebula behind is directly related to the way of human development in the future!If the temperature continues to decrease, then another way of technological development and life needs to be adopted; if the temperature is constant, it is the previous plan; if the temperature rises, the last defense measure has to be taken-isolate the planet directly from the sun , to prevent the temperature from being too high; the ground is completely powered by nuclear energy and illuminated by cold light.Of course, no one wants this to be the last situation.

Detecting the space behind is not something that can be decided in a few words. The space of the universe is too large. Even if it is a relatively simple way of intercepting the light of the universe, it will take a certain amount of time.Not to mention, in order to make the data more accurate, it is necessary to actively detect, such as using radio telescopes, to actively search for data; this time will last at least one year.Of course, with proper partial data validation, it can be done in a short time.

In space, the superstring communication device brings powerful communication capabilities to Venus, and can contact the detectors within the range of the Oort cloud within ten seconds—they are at least tens of billions of kilometers away from Venus and revolve around the sun It takes more than 7 Earth years to complete a circle!
In Nuoda's research room, there is only the sound of electronic equipment working, and everyone is waiting for the data information from the universe behind.

The detected areas are divided into 26 parts; however, the nebula and the solar system are in the process of rapid movement, and their areas continue to spread forward and superimpose, and the divided areas will advance by a gradient in just one day.

When the detector readjusts its angle, it immediately receives the light and radiation from the interior of the nebula. These radiations come from thousands of years ago and thousands of light-years away. Information is not particularly much.But it is undoubtedly enough to judge the temperature change only!

From the z-partition onwards, related data are continuously passed back, and groups of data continue to bring surprises to researchers.High temperature is not a good thing; the thick atmosphere of the planet itself is a natural cotton jacket-and if the temperature of space rises, it will inevitably lead to "heat stroke" on the planet, which will have a huge impact on the planet's ecology.

But now, scientists are pleasantly surprised to find that the temperature is dropping a little bit, and the rate of drop is very slow, but very uniform!But very firm!Almost every billion kilometers, the temperature drops by 1 degree Celsius!And according to the current relative motion speed of the solar system and this supernova remnant, as long as 12 years, the temperature gradient of the nebula will not drop by one degree Celsius!
"Accidental discovery! Okay, Dean Chen, you have made great contributions again." Zhang Chengye laughed.

"Again" made a "big" contribution!This sentence makes too many people only envious.Some people are so jealous that some people can't catch up with the flash of inspiration in their lifetime!

Back then, Chen Feng had an idea that shaped the powerful Starry Cannon!Not only a terrifying attack weapon, but also a super weapon with the ability to destroy planets, it is also an indispensable auxiliary equipment for the empire to explore space today!The probes sent to space today are all accelerated by star cannons!

And now, this guy even explained the temperature change of the nebula in one sentence!This question is so simple, but no one thought of it in a short time!And now, it was snatched away by this guy again!

This is science, sometimes 90.00% of inspiration is irreparable for [-]% of wisdom!You can't even find the direction, no matter how hard you try, it will be in vain!
