The five astronauts were stunned when they heard Liang Shui's words.

Not only them, but also on the Blue Planet, when they saw this scene on TV, they also felt very worried.

If they find something more powerful than humans here, then this trip to Mars will undoubtedly bring disaster to mankind.

But after Liang Shui thought for a moment, he quickly laughed again and said, "Hehe, my worry just now may be a bit exaggerated. If Mars really had intelligent creatures that were smarter than us humans, they might have attacked us a long time ago, right? ”

When the five astronauts heard this, they also breathed a sigh of relief in their hearts, and they all nodded and smiled.

One astronaut suddenly asked curiously: "Why is the North Pole of Mars hotter than the equatorial region?" Now that there is no ozone layer on Mars, solar radiation can shine directly on Mars, and the situation should be similar. ”

"Yes, it's really incredible, the poles are less exposed to the sun, and it stands to reason that the temperature should be lower than the equator." Another astronaut also chimed in.

As for the remaining three astronauts, they turned their heads to look at Liang Shui with a puzzled expression.

At this moment, on the ground of the Blue Planet, the people who received this information also moved their eyes to Liang Shui, hoping that he would give an answer.

Obviously, everyone wants to understand why.

But seeing Liang Shui staring at the gray-white sky for a long time, he suddenly laughed: "Haha, I understand."

Because the dry ice layer in the void at the poles of Mars is like a giant mountain, and the reason why the dry ice cloud contains a large amount of solid ice water.

It is not only like a cave in a flat place, because the sun can't shine, the cold wind can't blow in, and it's warm in winter and cool in summer. And it's more like sea water, the change of cold and heat is not so obvious, so it is also warm in winter and cool in summer.

In words that are easier for everyone to understand, this dry ice cloud is somewhat equivalent to the ozone layer on our blue planet, which has a certain blocking effect on solar radiation, so that the poles of Mars form a reading space that is different from the rest of Mars. ”

The five astronauts listened to Liang Shui's analogy and felt that there was some truth.

However, one of the astronauts shook his head and said: "Although Mr. Liang is very reasonable, the temperature here has also reached the conditions for cold-tolerant creatures to live." And now it should be late autumn on Mars, if it is summer, the temperature may be higher, and it will be more suitable for the existence of organisms. But we ignore the question of how organisms can survive without oxygen, and that is that there is no oxygen. ”

Liang Shui waved his hand and said, "What you said is very reasonable, but I also want to refute you." Maybe we can't find the existence of living things at the poles of Mars, but I think it should be much easier to find proof of the existence of living things. And I also want to say that maybe there are some creatures in the universe that don't need to rely on oxygen, and if we can't break this conclusion, we will find extraterrestrial creatures, I'm afraid it will be very difficult. ”

Science is originally developed by bold speculation and hypothesis, and then step by step argumentation, as long as it is not an iron law that has been established, it can be questioned, and it will not make people laugh.

So when the astronaut listened to Liang Shui's words, he just nodded slightly, but he didn't say anything.

Liang Shui smiled and said, "Hehe, let's not talk about this, let's hurry up and find life on Mars." It's still the same as before, don't separate, or it's too dangerous. ”

Everyone responded, and followed Liang Shui to explore carefully at the North Pole of Mars.

Liang Shui took five astronauts, while walking, while holding a thermometer to test the temperature, when they came to a place where the temperature was the highest, even exceeding zero degrees Celsius, Liang Shui quickly waved his hand, asked everyone to stop, took out light tools, and began to dig.

An astronaut first propped up the shelf, and then Liang Shui and the other four astronauts hurriedly took their own tools to help build it.

Soon, a simple derrick was erected.

The exploration drill is made of micro and nano materials in Liangshui, which is very tough, even if it is a diamond, it can be easily punctured, and it is not easy to break.

Whining......

As soon as the electric switch was turned on, the probing drill began to drill down to the Martian surface.

Liang Shui: The main reason for them to do this is to analyze the structure of the rock here to determine if it is more likely to have life.

Whew......

However, to their surprise, they had just been drilling into the ground for a short time when they heard a strange noise.

"It's water, water, water......"

The five astronauts couldn't help but laugh very happily when they turned their heads sideways and saw the liquid material that had been made out of the exploration drill.

Although the temperature in this place is higher than others, exceeding zero degrees Celsius, and there is a lot of solid ice water on Mars itself, it is not surprising that there is water now.

Liang Shui turned his head sideways, but he was slightly stunned, waved his hand and said, "Wait, that doesn't seem to be water." It's too viscous to be water. ”

After speaking, he quickly took out a test tube from the white box similar to a medical box on the back of the astronaut next to him, carefully collected it, and then used the super equipment to improve his eyesight by 100,000 times, and carefully looked at what was in the liquid.

"Cells, living cells!"

When he saw that the green liquid in the test tube was living cells, he couldn't help but exclaim with wide eyes.

The people on the ground of the Blue Planet, seeing Liang Shui's discovery on Mars on the screen, were also stunned one by one, their eyes widened, and they covered their mouths.

"Life, there really is life on Mars!"

Everyone immediately shouted loudly, and they were all very excited, not only the Chinese people, but also all the people in the world.

Because they know what it means to discover life on Mars.

This means that the existence of living things, perhaps not necessarily certain substances, as one might think.

The astronaut who refuted Liang Shui just now, after collecting the green liquid and discovering that there were living cells in it, felt incredible and red at the same time.

Now he finally knows that where life exists, oxygen may not be needed.

It's like groundwater with very low oxygen levels, and craters, where there are organisms.

And he quickly thought of an analogy, that is, if he was a fish in the sea and was used to that kind of environment, he might think that there would be no fish in the freshwater environment, but the facts proved that saltwater fish really can't live in freshwater, but there are indeed different saltwater fish in freshwater.

Bang......

Just when Liang Shui and the five astronauts were excited about the discovery of life, they didn't expect a deafening loud noise to suddenly sound in their ears, and then the earth trembled.

It looks like an earthquake! (To be continued.) )
