When it comes to burrowing technology, humans have made little progress at all.
It’s about the same as it was in the last century.
Because humans do not have this need.
The biggest demand is to remove deep oil.
These oil wells are due to commercial needs.
That’s why there was a breakthrough in the depth of the Kola ultra-deep drilling.
In everyone’s impression, it is easier to enter the earth than to go to heaven.
But Ye Zhen has now reversed this stereotype.
“Everyone knows that our current technology has long been able to build a space station in space.
And if necessary, we can actually build a base on the moon.
After all, we all have these technologies.
But it’s like what I told everyone before.
Space is actually a vacuum environment that needs to be solved.
Just isolate it from the vacuum environment of space.
But we humans don’t even have the perfect technology to enter the deep sea.
Far fewer people have entered the 10,000-meter depth of the ocean than have landed on the moon.
Everyone can know from here.
It is more difficult to dive into the deep sea than to go into space.
If you look at it from a physical perspective.
The difficulty of surviving in space is just the vacuum environment.
Beyond that is some cosmic radiation.
Basically it can be solved very simply.
What about activities in the deep sea?
Seawater is pervasive, except for the problem of water seepage.
There is another problem in the deep sea that does not exist in space.
That is the high-pressure environment of the deep sea.
The high pressure in the deep sea requires submarines to have very high pressure resistance.
Because it only takes a little gap or mistake to flatten the submarine.
Space is in a gaseous state, and the deep sea is in a liquid state.
The underground world deeper than the deep sea.
That's completely solid state.
It is more difficult to drill than the deep sea.
Not only high pressure but also high temperature.
So entering the earth is the most difficult of the three. ”
After listening to Ye Zhen’s popular science, everyone has a new understanding.
Everyone used to think that going to heaven was the most difficult thing.
I didn’t expect that entering the ground would be the most difficult.
After all, everyone has come into contact with the land and has dug it to some extent.
How difficult is it to dig a hole?
But now the audience seems to understand a little bit what Ye Zhen means.
"From what Ye Shen said, the space station seems to be the most technically difficult."
"On the space station, all you need to do is isolate the outside world and provide sufficient oxygen inside."
< br>“But it’s different if you’re in the deep sea.”
“In the 10,000-meter-deep sea, you can only be in a sturdy submarine.”
“It’s impossible to wear it at all. Wearing a wetsuit for deep diving”
"There is also the underground world, which is more difficult than the deep sea."
So everyone seems to understand.
Why are civilizations that can build an underground world more advanced than us?
Professor Yan Xin based on what Ye Zhen said.
I analyzed it in my mind.
"If we follow Mr. Ye's words."
"Mr. Ye means that the civilization that lives and develops on the surface of the planet is the most advanced."
"Because on land, With all kinds of abundant resources and open-air minerals, it is very easy to develop civilization. "
"The second step is to build space directly near the earth like now. Station.”
"This is a higher level of technology."
"For example, now we want to colonize other planets." "Build a moon base or a Mars base."

“The space station is to accumulate experience in surviving in space.”
Speaking of this, the people in the psychic laboratory thought of a piece of news that was not new.
That is the two astronauts from the American Boeing Company.
The space program was originally planned to last eight days.
Because of the malfunction of the spacecraft, they have not come back yet.
Forcibly being on the space station turned into an eight-month plan.
This once made the American Boeing Aerospace Company a global joke.
The two astronauts are still on the space station.
“If it is higher than the space station, it means that we can build buildings and survive in the deep sea.”
“For example, build a base directly in the Mariana Trench.”
Scientific fantasy like this existed in science fiction novels very early on.
That is "Twenty Thousand Leagues Under the Sea".
However, there is actually a problem with the translation of "Twenty Thousand Leagues Under the Sea".
In fact, a more accurate translation should be "Twenty Thousand Leagues Under the Sea".
The data of twenty thousand miles under the sea is not consistent.
"Twenty Thousand Leagues Under the Sea" is in the list of foreign books that must be read after class in elementary schools.
If anyone really thought about it.
Do you wonder why the depth of the sea is 20,000 miles?
Obviously this is not consistent with the data we currently measure.
Because others actually said twenty thousand leagues.
The league is an ancient marine counting unit.
To put it simply, it is the difference between nautical miles and kilometers.
Li is just the abbreviation for kilometers in our general sense.
It's like you shortened the sea miles to miles.
Kilometers and nautical miles are basically two different concepts.
1 nautical mile = 1.852 kilometers.
It’s just that when translating, it may be to make it easier to understand.
It is also possible that the translator did not know this aspect at the time of translation.
He directly translated Lige into Li.
So "Twenty Thousand Leagues Under the Sea" should be correctly called "Twenty Thousand Leagues Under the Sea".
It’s just that we haven’t achieved the technology in “Twenty Thousand Leagues Under the Sea” yet.
The only thing that came true was the submarine.
In the psychic laboratory, Wu Xueyao thought of what Ye Zhen said before about returning to the ruins.
“If it is sorted like this, is it true that the Heavenly Palace was built in the sky?”
“The technology is not as advanced as the civilization in Guixuli?”
Professor Yan Xin When I heard it, I was fascinated for a moment.
"Logically speaking, this is indeed the case."
“Compared to building a base on the moon.”
“It is more difficult to build a base in the deep sea.”
“But the most difficult thing is to build a city underground. "
"Among these, this is the most difficult and the most technological."
In the psychic laboratory, I heard Professor Yan Xin reasoning like this.
This is indeed the case in reality.
There are fewer people on the surface than those in the space station, those who have entered the deep sea, and those who are in the underground world.
The sorting is this sorting, which also represents the difficulty of entering these places.
If you didn’t know before about the high technological level of super-ancient civilizations that can enter the underground world to avoid disasters.
Now everyone has a completely new understanding.
Because so far, our deepest drilling has only reached one-third of the mantle.
It has not been fully drilled yet, and it is far from reaching the Moho interface.
And it was only explored through a hard drill bit.
It is not that people reach a place more than 12,000 meters away.
And more than 12,000 meters has exceeded the depth of the Mariana Trench.
But even in the Mariana Trench, some of us have gone to the depths in submarines.
But the underground world is a completely unknown area for us humans. (End of this chapter)
