"Okay, we're here! Dapeng did a good job this time and debugged it very accurately." Brother Hai got out of the car and opened the car door for the two who were still in shock.

Chen Shuxian got out of the car and then realized that the so-called speed reduction device was a blue viscous substance.

The elastic car plunges into the viscous substance, and the kinetic energy is gradually absorbed, thereby achieving slowing down.

The Moxing Base is an egg-shell-shaped building, which is the most commonly used architectural structure in Mozi Technology's alien base, because the egg-shell-shaped building can disperse all forces to various parts of the egg-shell under the pressure.

At this time, the catapult car set out again and shot towards the location where the Pilot was located, which should be to pick up the remaining crew members.

There is an iron rule at Moxing Base. When night falls, all crew members must return to the base.

Chen Shuxian looked at the sun. Since it was far away from the sun, the disc-sized sun on weekdays looked only as big as a fist.

At this moment, the sun is in the center of the sky.

"There are 30 minutes left. I hope the ejection vehicle has time to take all the crew!" Brother Hai looked at the ejection vehicle that was leaving, a little anxious and uneasy.

One more hour...

Chen Shuxian was puzzled: "Brother Hai, the sun is clearly in the sky, and there are at least 5 hours before the sun sets. You have calculated the wrong calculation."

"That's right, the position of the sun in the sky is related to the angular velocity of the star body. The angular velocity of the earth is 4.167×10-3 degrees/second, while the angular velocity of the Mo Star is as high as 41.67×10-3 degrees/second. So the day on the Earth is 24 hours, while the day on the Mo Star is only 2.4 hours. So now there are only less than 30 minutes left before the Mo Star enters the night." Hai Ge explained.

"So, what will happen after dark? Are there any beasts?" Chen Shuxian couldn't help but worry. There were more than a dozen crew members on the Pilot, and the ejection vehicle could only carry three people at a time. The ejection vehicle needed at least 5 round trips before it could take everyone over.

"Beast?" Brother Hai looked up at the sun, his silver space helmet shining under the faint sunlight.

"Mo Star is all composed of an element with unknown attributes. The scientists of this element Mozi Technology used all the means they could think of, and they could not detect it. But it can be clear that there is neither land nor river on Mo Star, so there is no condition for the birth of life."

"No matter what type of beast is, it is essentially a kind of life, so life cannot exist on Mo Star at all."

"But there is something more terrifying than a wild beast on the Mo Star, temperature!"

"Temperature?" Chen Shuxian couldn't help but take a step forward, feeling confused.

On the earth, the seasons include spring, summer, autumn and winter, and the weather is hot and cold. In winter, the weather is severe, and humans wear thick down jackets and turn on the heating to keep the cold. In summer, the weather is hot, and humans wear thin clothes and sit in air-conditioned houses to escape the heat. This change is due to the changes in temperature in different seasons.

The human living environment is closely related to temperature.

Some scientific research believes that if the global average temperature rises by 1 degree Celsius, the ice and snow in the Antarctic Circle will melt and the ocean coast will be deeply hit by hurricanes. It will face severe long-term drought in areas far away from the ocean.

The global average temperature rises by 2 degrees Celsius, the glaciers in Greenland begin to melt, coral reefs gradually disappear, and global sea levels rise by seven meters. Cities and some island countries along the ocean coast will be flooded by sea water.

The global average temperature rises by 3 degrees Celsius, the Amazon rainforest gradually disappears, extreme weather will become the norm on the earth, Europe will continue to suffer from previously rare heat waves in summer, and tens of millions or billions of refugees migrate from the subtropical to the mid-latitude areas.

The global average temperature rises by 4 degrees Celsius, Antarctica will disappear and the earth's land area will shrink greatly.

...

When the global average temperature rises by 20 degrees Celsius, the entire earth will become a purgatory on earth. 95% of the earth's organisms, including humans, will perish, and the living creatures suffer from frequent and deadly storms and floods. Hydrogen sulfide and methane cause fires from time to time, just like an atomic bomb that explodes at any time.

Rising temperatures can threaten the survival of organisms, and falling temperatures can also cause serious consequences.

However, due to the existence of heat from the sun and the core of the earth, it is generally believed that there are not many cases of significant temperature drop on the earth.

Some scientists estimate that after the global average temperature drops by ten degrees Celsius, the ocean plane will decrease due to the formation of more glaciers, and the originally subtropical areas will drop to the temperature of the cold zone. In this case, humans may survive using nuclear power plants, but the ecological balance will be destroyed and many species will be unable to escape the fate of extinction.

However, the reason why temperature changes cause serious disasters is a long-term and continuous process.

Human beings are no longer primitive people millions of years ago.

The primitive people were covered with animal skins in the severe cold, hid in caves and lit the wood collected from the primitive forests, and hugged together to keep warm.

Modern people have invented various heating equipment, air conditioners, heating and other equipment, which can hide comfortably in a warm room.

Therefore, current technology is enough to maintain a person's short-term survival at hundreds of degrees Celsius and tens of degrees Celsius below zero.

What's more, Mozi Technology has long invented a spacesuit for astronauts that can be heated on their own.

How could you be afraid of warm changes?

"You know the absolute zero degree, right?" Brother Hai looked at her puzzled expression, naturally understood what she was thinking and explained.

"Absolute zero...will there be such a low temperature here?" Chen Shuxian, as a spanking scientist at Mozi Technology, naturally understood what absolute zero meant.

There is no upper limit for the temperature. The human body temperature is 36.5 degrees Celsius, the temperature when water boils is 100 degrees Celsius, the magma erupted by volcanoes is 1200 degrees Celsius, while the temperature on the surface of the sun is about 5500 degrees Celsius, and the center temperature is as high as about 20 million degrees Celsius.

So is the temperature in the center of the sun the upper limit of the temperature?

no!

The highest temperature known to humans is created by humans themselves.

When the atomic bomb explodes, its core temperature can reach 350 million degrees Celsius.

In the Large Hadron Collider, humans have calculated the highest temperature in the universe. When two protons collide at ultra-high speeds, these particles are divided into quarks. The collision point will generate extremely high temperatures, and their temperature can reach 100,000 times the temperature of the solar center, and the temperature at the collision center is even higher.

However, the so-called maximum temperature is far from the upper limit of temperature. For example, during the Big Bang, the almost unmeasurable temperature of the singularity must be much higher than the temperature generated by particle collisions in the collider.

There is no upper limit for temperature, but there is a lower limit.

Because the essence of temperature is a function of state, it is used to describe the intensity of the thermal motion of atoms inside an object. To put it bluntly, it is the average kinetic energy of particles inside a matter.

When this average kinetic energy approaches zero infinitely, the temperature reaches the so-called lower limit.

This lower limit is absolute zero, which is minus 273.15℃.

but.

Although scientists have measured absolute zero, they have never found absolute zero in the universe. Even the Bumoran nebula hidden in the dark corner of the universe has an internal temperature of minus 272℃, which is 1.15℃ higher than absolute zero (minus 273.15℃).

In geophysics, there is a famous law called the third law of thermodynamics. It describes that the entropy of a thermodynamic system tends to a fixed value when the temperature approaches absolute zero. For a complete crystal, this fixed value is zero.

This obscure law can actually be expressed as: In the universe, it is impossible to cool an object to zero degree of absolute temperature.

The third law of thermodynamics can become a law, which is enough to show that absolute zero does not exist.

Mo Xing is in the solar system, and is naturally part of this universe. How could he violate the third law of thermodynamics?

"Brother Hai, this sounds too civilian, right?" Chen Shuxian showed suspicion.

Brother Hai shook his head heavily: "Oh, I also hope that there is no so-called absolute zero on Mo Xing, so the first batch of scientific expedition team members will not have to sacrifice."

Chen Shuxian was very surprised when she heard this and asked: "Brother Hai, why haven't I heard of the death of a scientific expedition team member?"

After the establishment of the Earth Defense Bureau, considering that its office funds and scientific research funds come from all mankind, the Earth Defense Bureau will regularly publish information on the planning of the Earth Defense Bureau. For example, the construction of nuclear fusion power stations, the progress of the second phase of the Mars base project, and even the toilet paper usage of 2,000 bathrooms in the Earth Defense Bureau.

Some social critics conducted field investigations on all projects of the Earth Defense Bureau when information disclosure was skeptical, and found that the Earth Defense Bureau had no concealment. The information they disclosed was all complete information about the ongoing projects.

There is no information about the death of the scientific expedition team members!

"Of course, humans on Earth don't know about this information, because the Moxing scientific expedition plan was initiated by our Mars base, and its funding comes from Director Li Mo's private sponsorship. It does not need to be explained to the human world. Moreover, all the scientific expedition members are members of the Mars base. They no longer belong to humans on Earth in the legal sense." Brother Hai explained with a heavy voice.

At this time, Chen Shuxian was about to continue asking questions when a silver light rushed over from a distance. The silver light hit the blue viscous substance of the white eggshell building. Since there was no air on the ink star, the sound could not be transmitted, and Chen Shuxian could not hear the sound.

But looking at the body of most of the blue viscous substance deep into the car, she also knew that the impact this time was much more serious than the one just now.

Sure enough, the blue viscous substance slowly "spouted" the elastic car and returned to its original state.

The door of the elastic car opened, and the thin old man Wu Shu took the lead in breaking free and moaned in pain: "You are going to kill me, the old man! No matter how Li Mo begs me next time, I won't come!"

Following closely behind is a crew member of the Pilot and the "Language Curse" Wang Ming.

Through the helmet of the space suit, Chen Shuxian could see that Wang Ming's mouth had been completely sealed with tape. He looked frightened and looked around as soon as he got off the car.

"Wang Ming, don't worry, this is the Moxing base, we will not give up on you." Chen Shuxian understood that he was worried about his own situation and comforted him.

Wang Ming nodded slowly.

"Okay, you all go in first, Dapeng, take them to the base lounge." Brother Hai told a tall staff member behind him.

This staff member named Dapeng walked to the black gate.

A ball popped up above the black door, which was dark green, and dozens of cameras and sensors were spread all over it.

The ball emitted several red and blue beams of light, stragging on Dapeng. Ten seconds later, the mechanical sound rang out: "Verification passed, member ID Moxing Base No. 1061, name Liu Dapeng, position as the base safety protection officer, welcome to enter."

The sound fell and the black door slowly opened.

"Get in, compatriots on Earth!" Liu Dapeng made a call.

"Who are you scaring me so formally?" Wu Shu muttered, and Wang Ming, who was a little confused after pushing him, walked into the door together.

"When you enter the door, someone will receive you!" Liu Dapeng said in the phone, then waved his hand and closed the black door again.

Only then did Chen Shuxian realize that the black gate also had an arc shape, with a curve very similar to the eggshell. From the outside, there were almost no traces of them except for the different colors.

It seems that the door has a good seal.

After sending the three people to Moxing Base, Liu Dapeng took out a controller from his pocket, clicked a few times, and the ejection car started again.

"Brother Hai, you just mentioned that the team members selected by the Moxing Research Institute for the first time were all members of the Mars base. Why not choose Earthlings?" Chen Shuxian continued to ask as the catapult car disappeared under the horizon.

"This... I don't know either. The specific plan was handled by Director Li Mo." Thinking of the situation at that time, Brother Hai was puzzled.

"At that time, it was when the Earth Defense Bureau was attacking the Shenshan Mountain. Because it was impossible to predict whether the spaceship in the Shenshan Mountain would escape in the chaos and fly to Mars, I could only order the Mars base to strengthen its vigilance. At the same time, the air defense system installed on the surface of Mars has entered a level one combat readiness state."

"At this moment, the communication room of the Mars base suddenly received a message from a spacecraft asking for landing. At that time, my heart suddenly jumped and almost pressed the missile launch button of the air defense system, because the spacecraft that can fly from Earth to Mars, besides the Pilot, the spacecraft of the Shenshan Zuren."

"According to the information released by the Earth Defense Bureau, the Pilot should be transformed at the Gobi Desert base. Then the sudden appearance of the alien spacecraft must have been sent by the ancestors. The Mars base instantly entered the special combat readiness state, and all the staff were fully armed, and even the bombs buried at the bottom of the base were activated."
