Earth Era

"That's why there are those obscure words in the conversation between the plasma lifeform and your brother." Zhao Huasheng said, "This is a kind of lifeform that is completely opposite to us. We humans rely on eating to supplement energy. To survive, plasma lifeforms rely on eating to lose energy in order to survive."

Li Wei murmured: "The primary task of life is to survive, but the essence of survival is not to obtain energy from the outside world to maintain its own operation, but to expel its own energy to the outside world to maintain its own operation. Also...it's cold outside, I Will be exhausted."

"Yes, that's it." Zhao Huasheng said.

Li Wei continued to mutter: "I want to go out...Aren't you afraid of dying?...If you help me, I can adapt...Okay, I'll help you..." Li Wei hugged her head in pain, her eyes glowed Tears started to flow, "My brother helped it, helped this demon to get it out..."

"Yes." Zhao Huasheng said, "I don't know what method your brother used to help this plasma life form acquire the ability to resist low temperatures, but there is no doubt that your brother did it. Then the life form It left the solar environment simulator and came to the outer space freely. According to my speculation, the ability of this living body to resist low temperature has a certain limit. At least, it has no way to leave the earth and return to the sun by itself .It still gained the ability to go to the sun with the help of your brother."

"Sun Gemini Exploration Program?" Li Wei asked.

"Yes. The two satellites of the Sun Gemini Exploration Program." Zhao Huasheng said, "I can be sure that your brother tampered with those two satellites. One of the satellites was modified by your brother and became The vehicle of the plasma lifeform, and then the satellite lost contact with the earth before reaching the sun, and then it directly hit the sun, so... the plasma lifeform also came to the sun."

"The other satellite is equipped with devices such as laser transmitters. Obviously, this satellite is responsible for communicating with the plasma life forms that live on the sun. In this way, a complete communication The chain was constructed... The plasma life sent out signals by changing the luminosity of a certain part of the sun, and these signals were picked up by the Vulcan solar telescope. Your brother sent the signal to the plasma life through that satellite, In order to realize the exchange of information between the two parties.”

"Why can't that satellite be responsible for both receiving and sending out signals?" Li Wei asked.

"Because it can't be done." Zhao Huasheng replied, "The Scarlet Heart spacecraft is a whole spacecraft, so it can be equipped with such a high-resolution telescope, and this is just a satellite. It can't do this. Therefore, the one who assumes this responsibility can only be the Vulcan telescope."

"Why in the past, the messages from those plasma life forms could be received only through the Vulcan telescope, but now, it is necessary for the Red Heart spacecraft to adjust to the highest resolution at such a close distance to receive it?"

"The reason is very simple. One is active communication and the other is passive communication." Zhao Huasheng said, "I'm almost sure that a single plasma life form has a very low ability to change the luminosity, so in the past, they were a combination of many life forms. Together, only by working together to change the luminosity can the signal detected by the Vulcan telescope be sent out. This...that is, in the data that was restored last time, the plasma lifeform said, "I'm sorry that I haven't contacted you for a long time... ...I have had many companions...with no means of contacting you by my own strength"the reason for these words."

"In the past, the Vulcan telescope detected the luminosity signal sent by many plasma life forms to the earth... But now, what the Red Heart spacecraft detects is the signal sent by an unsuspecting single life form changing the luminosity .”

Li Wei nodded silently.

"Next, let's talk about the oasis reconstruction plan and the basis for my prediction that the sun's surface temperature will stop decreasing when it drops to 4,500 degrees Kelvin."

"Although you are not a stellar physicist, you should also know some common sense. Then let me ask you... what are sunspots?"

Li Wei was a little puzzled, but still replied: "Because of certain solar activities, some low-temperature regions will appear on the surface of the sun. Because of the low temperature, they will appear darker in color, so they are called For sunspots."

"What's the temperature of the sunspot?" Zhao Huasheng asked immediately.

"4500 degrees Kelvin... Ah, I see." Li Wei said, "The so-called oasis of the plasma life form... refers to the sunspots? Because the temperature of the sunspots is relatively low, they can be better here. Keeping their bodies, that's why they call sunspots oases?"

Zhao Huasheng nodded slowly.

"Then...the oasis transformation plan is to turn the surface temperature of the entire sun into the temperature of sunspots, and turn...the entire sun into an oasis? Is this the truth about the decrease in the temperature of the sun's surface?" Li Wei was shocked. covered his mouth.

"Yes. This is the basis for me to conclude that the temperature of the sun will not continue to drop." Zhao Huasheng said indifferently.

"What is the isolation zone?" Li Wei responded quickly, "I remember that plasma life body once said that there are isolation zones around the oasis, and many companions will die if they cross the isolation zone."

"As you can imagine, the isolation zone is the surrounding area of ​​sunspots." Zhao Huasheng said, "Sunspots are formed by the strong magnetic field above the sun. Although the temperature of sunspots is lower than the surface temperature of the sun, the temperature of the surrounding areas of sunspots But the temperature is higher than the surface of the sun. Surviving on the surface of the sun is already extremely difficult, and passing through those high-temperature isolation zones will naturally bring them greater casualties. This is the truth about the isolation zone.”

"And...the appearance of sunspots is usually very short. This means that a sunspot area will disappear after a period of time, and the plasma life will be exposed on the hot surface of the sun again. In order to survive, In order to expel the excess energy in their bodies to maintain their shape, they have to continue looking for the second sunspot... Their life course is in the process of looking for sunspots - sunspots disappear - continuing to search for sunspots. .”

"It is conceivable that it will be a very difficult time." Zhao Huasheng sighed, "The plasma life has experienced too many deaths and tribulations, and has experienced too many life and death. Their comrades may die, and their relatives may die. Dead, friends may be dead... They also want to get a peaceful and stable life. So, as we all know, for the continuation of life, they launched the oasis transformation plan to transform the entire sun into an oasis .”

"The oasis transformation plan has finally succeeded. Plasma life forms have lived a happy and peaceful life. They are doing well, but our earth civilization is about to perish." Zhao Huasheng said quietly, "It is precisely because I already know the power of the sun. I am worried about the Moth impactor because of the existence of plasma life on Earth. And as I expected, after the Moth impactor hit the sun, the Red Heart spacecraft was hit by plasma The attack of living beings. But our luck is a bit better, the Red Heart spaceship withstood the attack and was not destroyed."

"Why didn't the plasma beings launch a second attack?"

"This involves the technological development model of plasma civilization." Zhao Huasheng said, "Although plasma life can develop the technology to build Dyson spheres similar to K2 civilization, but... in other respects, their technology may be better than ours. Still lagging behind. For example, our human civilization is now a K0.7 level civilization, if the technology to cure AIDS belongs to a K1.1 level civilization, then...if our human civilization devotes all social resources to the research on AIDS Among them, we can still research this technology in a maximum of ten years. In this way, we have mastered the technology of K1.1 civilization at the technological level of K0.7 civilization. But you have to understand, This does not mean that we have become a K1.1 civilization."

"Why didn't we do this?" Zhao Huasheng said quietly, "Because AIDS has not had a fatal impact on our civilization. In other words, we have no urgent motivation to solve AIDS. But...plasma life is different. The surface environment of the sun has seriously affected the continuation of their race. If this problem is not solved, their civilization race may become extinct. So...they put all their energy and resources on this problem, and gathered the entire The power of civilization has finally mastered the technology to create a reverse fusion layer when other technologies may still be very low-level."

"There are precedents for this in our civilization. Think about the previous era of countries. During the Cold War, when the combined computing power of major powers in the world was not as good as the computing power of a smartphone today, they They have already landed on the moon. And this...is only the strength of a country, and the urgency of landing on the moon has not reached the point where you will die if you fail to land."

"So...the reason why the plasma civilization didn't launch a second attack on the Scarlet Heart spacecraft, according to my guess, is that they don't have the corresponding technical means. They don't even know whether the first attack destroyed the target. Even the first attack is just a large-scale attack in a general direction."
