Earth Era

"That's why there are those obscure words in the dialogue 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 obtain energy. to survive, and plasma life forms survive by losing energy by eating."

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 discharge its own energy to the outside world to maintain its own operation. Also... It's cold outside, I will Die."

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

Li Wei continued to murmur: "I'm going 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, tears began to flow in her eyes Come out, "My brother helped it, helped this demon get it out..."

"Yes." Zhao Huasheng said, "I don't know what method your brother took to help this plasma life form obtain the ability to resist low temperature, 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 life 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."

"Solar Gemini exploration plan?" Li Wei asked.

"Yes. The two satellites of the Sun Gemini Exploration Program." Zhao Huasheng said, "I can be sure that your brother has played tricks on those two satellites. One of the satellites was transformed by your brother and became a The plasma lifeform's ride, and then the satellite lost contact with Earth before it reached the sun, and then it hit the sun directly, so...the plasma lifeform came to the sun."

"The other satellite is equipped with a device such as a laser transmitter. Obviously, this satellite is responsible for communicating with the plasma lifeforms living on the sun. In this way, a complete communication The chain is constructed... Plasma life sends signals by changing the luminosity of a certain part of the sun, and these signals are picked up by the Vulcan solar telescope. Your brother sends a signal to the plasma life through that satellite to This enables the exchange of information between the two parties.”

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

"Because it can't be done." Zhao Huasheng replied, "The Crimson 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, it can only be the Vulcan telescope to undertake this responsibility."

"Why in the past, as long as the Vulcan telescope was used to receive the information from those plasma lifeforms, now, the Crimson Heart spacecraft needs to be at such a close distance and adjusted to the highest resolution to receive it?"

"The reason is very simple. One is active communication and the other is passive communication." Zhao Huasheng said, "I am almost certain that the ability of a single plasma lifeform to change the luminosity is very low, so in the past, they were many lifeforms united in Together, the luminosity can be changed together to send out a signal that can be detected by the Vulcan telescope. This is... in the data that was restored for the last time, the plasma lifeform said, "I'm sorry I haven't contacted you for a long time... I With many companions...I can't get in touch with you by my own strength"The reason for these words."

"In the past, the Vulcan telescope detected the luminosity signal sent by many plasma lifeforms together to the earth... Now, what the Crimson Heart spacecraft detected was the signal of a single lifeless body changing its luminosity. "

Li Wei nodded silently.

"Next, let's talk about the oasis renovation plan, and the basis for my prediction that the temperature of the sun's surface 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 I ask you... What are sunspots?"

Li Wei was a little puzzled, but still replied: "Because of some solar activity, there will be some low temperature areas on the surface of the sun, because the temperature is lower, so they will show a darker color, so they are called it. For sunspots."

"What is the temperature of the sunspots?" Zhao Huasheng asked immediately.

"Four thousand five hundred Kelvin... Ah, I see." Li Wei said, "The so-called oasis of plasma lifeforms... refers to sunspots? Because sunspots are relatively low in temperature, they can better maintain themselves here. body, so they call sunspots oasis?"

Zhao Huasheng nodded slowly.

"Then... the oasis renovation plan is to turn the surface temperature of the entire sun into a sunspot-like temperature, and to turn... the entire sun into an oasis? Is this the truth of the decrease in the temperature of the sun's surface?" Li Wei covered in shock. Shut up.

"Yes. This is the basis for my conclusion that the temperature of the sun will not continue to decrease." Zhao Huasheng said indifferently.

"What is the isolation zone?" Li Wei responded quickly, "I remember that the plasma lifeform once said that there are isolation zones around the oasis, and crossing the isolation zone will kill many companions."

"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 that of the sun's surface, the temperature of the surrounding areas of sunspots But it is hotter than the surface of the sun. Surviving on the surface of the sun is already extremely difficult, and crossing those high temperature isolation zones will naturally bring them more casualties. This is the truth of the isolation zone.”

"And ... sunspots are usually very short-lived. This means that after a period of time a spot area disappears, and plasma life is re-exposed to the hot surface of the sun, in order to survive, in order to Expelling too much energy from their bodies to maintain their shape, they have to continue looking for a second sunspot...their life cycle is a process of searching for sunspots - disappearing sunspots - continuing to search for sunspots."

"It is conceivable that it will be a very difficult era." Zhao Huasheng sighed, "Plasma life has experienced too many deaths and hardships, experienced too many separations, their comrades may have died, and their relatives may have died. Dead, friends may be dead... They also want to have a peaceful and stable life. So, as we all know, for the continuation of life, they started an oasis transformation plan to transform the entire sun into an oasis. "

"The oasis transformation plan has finally succeeded. The plasma lifeforms have lived a happy and peaceful life. They are doing well, but our earth civilization is about to perish." Zhao Huasheng said faintly, "It is precisely because I already know the nature of the sun. I was worried about the Moth Impactor because of the existence of plasma life on it. And as I expected, after the Moth Impactor hit the sun, the Crimson Heart spacecraft was hit by plasma The attack of the body life. But our luck is a bit better, the Crimson Heart spacecraft withstood the attack and was not destroyed."

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

"This involves the technological development model of plasma civilization." Zhao Huasheng said, "Although plasma lifeforms can develop technology to build Dyson spheres similar to K2 civilization, but... In other respects, their technology may be better than ours. To be backward. For example, our human civilization is now a K0.7 civilization. If the technology to cure AIDS belongs to a K1.1 civilization, then ... if our human civilization invests all social resources In the research on AIDS, we can still research this technology in ten years at most. 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 that this does not mean that we have become a K1.1 civilization."

"Why didn't we do this?" Zhao Huasheng said faintly, "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. Sun The surface environment has seriously affected the continuation of their ethnic groups. If this problem is not solved, their civilization ethnic groups may become extinct. So... they put all their energy and resources on this problem, and gather the entire civilization. Power, and finally mastered the technology of making reverse fusion layers when other technologies may still be very low-level."

"This has precedents in our civilization. Think back to the times of nations, during the Cold War, when the combined computing power of the great powers in the world was not as good as the computing power of a smartphone today. It has already landed on the moon. And this ... is only the power of a country, and the urgency of landing on the moon has not reached the point of death if it cannot be landed.”

"So...the reason why the plasma civilization did not launch a second attack on the Crimson Heart spacecraft, according to my speculation, should be that they did not have the corresponding technical means. They did not even know whether the first attack destroyed the target. Even In the first attack, it was only a large-scale attack in a general direction."
