The reason why Li Chen cast his eyes on Wang Dali at this time.
It was because Wang Dali was full of confusion.
He was born in a humble background and was busy making a living in his early years, so he didn't know much about a lot of knowledge.
Like so many human beings, they have no concept of the universe.
After all, for the vast majority of ordinary people.
The earth is already too big for them.
Many, many people have lived for decades, or even a lifetime.
None of them immediately opened the province in which they lived.
They don't even know how many countries there are on the planet they live on.
Which continents are these countries located on?
What customs and customs do they have, etc...
They may not be able to explain these very basic knowledge.
Not to mention thinking about the vast universe and starry sky beyond the earth.
Perhaps before the apocalyptic catastrophe erupts.
Even before Li Chen mentioned the area of the sixth star field just now.
these commanders.
Their understanding of the universe is only to the extent of "wow so many stars" and "wow so huge".
Based on the above objective facts.
Li Chen deliberately chose Wang Dali as an example.
Let other commanders who are in a similar situation to him.
Learn to improve your knowledge base.
Expand the understanding of some basic knowledge of the universe and strengthen related knowledge concepts.
Commanders at all levels below.
Everyone noticed Li Chen's eyes.
At this moment, he is watching Wang Dali.
So everyone looked at Wang Dali.
And Wang Dali himself also noticed Li Chen's gaze.
He's just not well educated.
Knowledge reserves are limited.
But some talents are innate.
Such as mental arithmetic ability.
Some people don't need any skills.
Complicated data can be calculated with just a glance.
And some people you even give him a calculator.
He also needs to press half a day.
In this regard, Wang Dali is one of the lucky ones.
He noticed Li Chen's questioning gaze.
At this time, Wang Dali almost didn't think about it.
The answer was given on the spot.
"Report!"
"General Commander!"
"If the Hyperloop travels at a speed of 1,500 kilometers per hour, it will take about 72,000 years to cover the distance of one light-year!"
Wang Dali answered Li Chen's question loudly.
And his face is full of confidence and confidence.
Hearing his answer, many other commanders showed knowing smiles.
Obviously this answer is the same as the calculation result in their minds.
Of course, there are still some commanders whose expressions are still full of hesitation.
Apparently they haven't come up with the results of their calculations yet.
"That's right. At the speed of the Hyperloop at 1,500 kilometers per hour, if you want to run from the south of Longguo to the north, it will take you only a few hours to run a straight line."
"Even if it goes around the earth, it only takes a little more than a day."
"However, I want to travel a light-year distance at this speed."
"But it takes a full 72,000 years!"
"Think about it again, the maximum diameter of our sixth star field is 1800 light-years."
"Calculated based on the most advanced means of transportation for human beings on the earth."
"To complete the 1,800 light-year journey, it will take about 130 million years."
"Dinosaurs have been extinct for several generations by this time."
"Now, do you know how precious wealth and how vast a star field we have on hand?"
Li Chen looked at all the commanders below with a faint smile.
There are absolutely no real idiots here.
He believed he had spoken so much.
these commanders.
Even if you have never seriously thought about, understood, or cared about this knowledge before.
Nor does it care how big the universe is.
Now that they have listened to their own description, they should have a new understanding and cognition of the star field they are in.
And in fact it is.
Because at this moment, Li Chen saw an expression of amazement on the faces of every commander.
Except Moli.
Mo Li is from the Pulit civilization empire.
She has been exposed to the universe since she was a child.
I am all too familiar with these concepts.
So what Li Chen mentioned couldn't arouse Mo Li's emotions at all.
"I really didn't expect that we still have such precious wealth!"
"Yeah, I thought the solar system was already very big. The fastest space vehicle for human beings has not left the solar system after flying for decades! I didn't expect that the area of the star field we are in is so large!"
"1,800 light years! It takes more than 130 million years to cross such a small distance. I heard correctly just now. Commander Li Chen said, this is just the sixth star field, right? It is the Orion spiral arm The tenth district's jurisdiction?"
"I'll go... so how big is the star field in the tenth sector of Orion's spiral arm?"
"I don't know, anyway, it must be beyond our imagination!"
"For me, the sixth star field is already a distance that I may not be able to go out in this lifetime, let alone the tenth district, or the Orion spiral arm."
"Brother, don't be discouraged, I'm just like you, even if my lifespan is increased by a hundred times, I'm afraid I won't be able to get out of the star field we are in now,"
"Good brothers, you are not alone!"
"Let me talk about a concept that will shock you even more. According to the information I know, the diameter of the Milky Way calculated by humans is about 100,000 light-years. The Orion spiral arm is only a small part of the Milky Way."
"..."
The words of party loyalty silenced all the commanders in an instant.
Everyone looked at the party loyally with a strange look on their faces.
As if to say are you a devil?
Why let us know such data?
One hundred thousand light years, what is that concept?
It is still calculated according to the means of transportation created by human beings with current technology that can transport living people.
At a speed of 1500 kilometers per hour on the hyperloop.
Want to span the entire galaxy.
About 72 trillion years.
What is the concept?
Regardless of the age of the unobservable universe.
The current age of the entire observable universe is about 13.8 billion years old.
In other words, even if human beings have been at their current highest level of technology since the birth of the universe.
Build the vehicle to drive.
Until today, 13.8 billion years later.
They didn't make it out of the galaxy either.
And you know, even the entire Milky Way.
Put it in the big frame of the whole universe.
It is only equivalent to a room with an area of 1,000 square meters.
Just a tiny speck of dust barely visible to the naked eye in the corner.
Even, this ratio is too large.
In fact, the size of the Milky Way is the ratio of the entire observable universe plus the unobservable universe.
It is much smaller than a room of 1,000 square meters and a speck of dust invisible to the naked eye in the corner.
