Chapter 672: New World
"It seems that the presence of a large amount of helium-3 on the moon is closely related to this artificial sun."
Xu You didn't know the lifespan of this artificial sun, but it seemed that it would be able to burn for at least a few hundred or a few thousand years without any problems.
Due to the limitations of the moon's internal space, the actual volume of this artificial sun is definitely not as large as the actual sun.
But from Xu You's position, this artificial sun looked as big as the real sun, and gave Xu You a very similar feeling.
According to the data measured by the space suit, the temperature outside the space suit is around 26 degrees Celsius, which is a very comfortable body temperature.
After careful observation, Xu You noticed a new detail.
"The position of this artificial sun seems to be always in the center ."
Because this is just an artificial sun, its actual distance from the ground is relatively close, and it does not change its position relative to the planet like the real sun.
Therefore, in theory, there is no night in the world inside the moon, but it is a world with eternal daylight.
Normally, such continuous daylight has a great impact on living things, especially plants. Long-term exposure to the sun will cause plants to die quickly.
Xu You didn't know whether there had once been a complete ecosystem here, or whether there was only one type of intelligent creature.
Or perhaps, all creatures that once existed in this world have adapted to this continuous daylight and do not need a dark environment to transition.
Walking in this new world, Xu You discovered more information.
Xu You can be sure that the world inside the moon is very rich and colorful.
There are various buildings here, some of which are also residential.
"This should be a place similar to a hotel, but this seems to be a villa? It seems that there are people living in the world inside the moon for a long time."
"If that's the case, why do we need to build underground shelters? Is it because the environment inside the moon is not safe enough?"
As he walked, Xu You was thinking about these questions in his mind.
Xu You felt that maybe at the beginning, the world inside the moon had not been developed, and the intelligent creatures were all in underground shelters. It was not until the moon began space travel that they began to develop the world inside the moon.
Of course, it is also possible that the space inside the moon is limited and it is impossible for all intelligent creatures to live in it, so they mainly live in underground shelters under the surface of the moon.
In addition to these various buildings, Xu You also discovered facilities such as roads and airports, but he did not see any means of transportation such as cars and airplanes.
"There are traces of intelligent life everywhere, but there are no signs of life... It's really hard to understand."
If all these intelligent lives had evacuated, it would be easy to understand.
But no traces of plants or even microorganisms were found, which is somewhat unreasonable.
After walking on the road for a while, Xu You stopped.
At this time, several hours had passed since Xu You came down from the black hole.
Xu You already felt a little hungry, but of course with Xu You's body, he could sustain himself for a few days without food or water.
But after that, the oxygen carried in Xu You's space suit will be exhausted first.
If Xu You can't find a way to get back outside quickly, he will need to solve the oxygen problem as soon as possible.
"Hmm? The gas composition in the air is actually..."
At this time, Xu You carefully observed the data measured by the monitoring system of the space suit and discovered some new situations.
Just now, Xu You only noticed that the oxygen content here was slightly higher than that in the underground shelter, but he did not pay special attention to the specific proportions of these gases.
Logically speaking, Xu You would not ignore these things, but the things here refreshed Xu You's cognition too fast, making Xu You a little overwhelmed for a while.
After carefully looking at these data, Xu You discovered that the proportion of various gases in the air here is very similar to that on the Blue Planet!
"Oxygen content: 21%. Nitrogen content: 78%. The rest is mainly rare gases, carbon dioxide, water vapor, etc...."
Xu You felt that this situation was no coincidence.
From all the previous signs, Xu You felt that these environments were very suitable for human survival. Now, this possibility has increased a lot.
After confirming that the air here was very suitable for human breathing , Xu You made up his mind and took off his helmet.
Taking a deep breath, Xu You felt that the air here was very sweet.
The "sweetness" here is naturally not any special smell, but just breathing it makes Xu You feel very refreshed.
Xu You didn't feel so comfortable when breathing in the Blue Star .
This is probably because the air on the blue planet has been polluted and contains various harmful gases, while the air inside the moon does not contain these harmful gases.
"The sunshine is very comfortable, and it feels like spring on a blue planet. The radiation protection function of the space suit is meaningless here."
After confirming that everything was safe, Xu You finally dared to take off his space suit and feel this new world with his body.
As it turned out, after taking off his space suit, Xu You did not feel any discomfort, but felt more comfortable.
Because of the special gravity system, the gravity here is not like the surface of the moon, where there is only one-sixth of the gravity of the Blue Planet. Instead, it has the same gravitational acceleration as the Blue Planet, about 9.8m/s^2.
Xu You felt more and more that this was a world prepared for the people of Blue Star.
"Perhaps, the planets there are very similar to Blue Star, including the composition of various gases in the atmosphere, the gravitational acceleration of the planet, the size of intelligent creatures, etc. Could it be that only the environment of Blue Star can give rise to life? Wait a minute..."
Thinking of this, Xu You suddenly had another idea.
This idea was so bizarre that even Xu You himself felt a little scared when he thought of it.
That is, these intelligent creatures actually discovered a planet like Blue Star by chance while traveling in space.
They felt that the Blue Star was very similar to their planet, so they stayed near the Blue Star and analyzed and observed it.
As for what happened later, Xu You didn't even dare to think about it anymore.
