Wan Changchun's words made Lin Dong, Tian Lao and others confused for a while.
What did they understand?
"High-dimensional time dimensions and timelines" Wan Changchun repeated excitedly, Lin Dong and Tian Lao were stunned for a moment, and then they showed the same happy expression as Wan Changchun just now, as if they suddenly understood. , "Yeah, why didn't I think of this?"
Mr.
Tian clapped his thigh and complained to himself.
When Su Yichen sent a message from Pluto, he was the first to know about how the Earth base would counterattack the Gaians, but at that time he was only immersed in it.
Amid the surprise, coupled with the fact that the war has just ended, Mr.
Tian, as the main leader of the northwest base, still has many tasks that need to be arranged immediately.
In fact, it was not only Tian Lao, but Lin Dong as well.
What's more, through contact with the desert base, they later learned that Wan Changchun and Hu Zhijun suddenly appeared.
After receiving this news, Tian Lao and Lin Dong almost immediately decided to leave for the desert base, thus ignoring an important point.
"What dimension and timeline Xiao Wan, what are they talking about?"
Seeing the three old people looking excited and even dancing and talking, Hu Gang was confused and couldn't help but quietly asked Wan beside him.
Yi.
Wan Yi didn't understand what made them so excited.
As a senior intellectual, although Wan Yi's major was only address exploration, he also knew a thing or two about the basics of physics.
He thought about it and said to Hu Gang: "The dimensions are actually very small.
It is easy to understand that according to Einstein’s theory of relativity, what we face in life is three-dimensional space, and then adding time makes it four-dimensional.”
Hu Gang was still a little confused after hearing this, and Wan Yi added: "Most of the four-dimensional space mentioned in daily life refers to the concept of "four-dimensional space-time" mentioned by Einstein in his general theory of relativity and special theory of relativity.
According to Einstein's concept, our universe is composed of time and space.
The structure of space is different from the three axes of length, width and height of ordinary three-dimensional space.
There is an additional time axis.
And this axis of time is an imaginary axis.
Simply put: the zero dimension is a point, with no length, width, and height.
The one dimension is a line composed of countless points, with only length.
There is no width or height.
Two-dimensional is a surface composed of countless lines, which has length, width and height.
Three-dimensional is a body composed of countless surfaces, and the four dimensions can be understood as directions. " Wan Yi copied the book and patiently explained to Hu Gang, but the more he said this, the more confused Hu Gang became.
After gesticulating for a long time, he still couldn't figure out what the other party meant.
"Haha, that's not how the theory is understood.
If you continue to explain like this, I think Xiao Hu will be confused for you."
After discussing with Lin Dong and Mr.
Tian for a while, Wan Changchun noticed what Wan Yi was explaining to Hu Gang.
What is dimension, what is time.
He couldn't help but laugh when he saw that Wan Yi couldn't understand anything while gesticulating, and Hu Gang was getting more and more confused as he listened.
"Grandpa, me."
Wan Yi's face turned red.
Just as he was about to say something, Wan Changchun interrupted him with a wave of his hand.
"Although you study science, you are not engaged in physics, and your job has nothing to do with it.
It is good to be able to recite the theories in the textbook.
There are specializations in learning, and there are teaching methods, so let's I, the stinky old nine, should explain it to Xiao Hu.”
Wan Yi nodded repeatedly after hearing this.
As for Hu Gang, of course he was willing to listen to Wan Changchun's explanation.
Lin Dong and Tian Lao looked at each other and smiled, listening attentively.
Wan Changchun started to explain what three-dimensional space is in a different way.

What is time again?
Wan Changchun was originally a professor at Shimen Institute of Technology.
Teaching is his job, and the teaching methods of teachers of his generation are completely different from those of today's teachers.
They explain the profound things in simple terms, combine theory with practice, and explain everything in a smooth manner.
In a few simple words, Wan Changchun explained the three-dimensional space in Einstein's theory of relativity.
Time, as well as four-dimensional space, were explained clearly.
After hearing this, Hu Gang suddenly understood and figured out what was going on.
"So Wan Lao, what did you, Lin Lao, and Tian Lao just say?"
Although Hu Gang understood.
But I still don't know why they looked suddenly enlightened just now, so I couldn't help but ask.
"Haha, let me ask you a question first."
Wan Changchun asked with a smile.
"Please."
Hu Gang nodded quickly.
Wan Changchun asked with a smile: "There was a hypothesis in our time.
I guess this hypothesis should still be clear to many people now.
In fact, it is a hypothesis.
To be precise, it should be a theoretical result proposed by Einstein in the theory of relativity. , simply put, Einstein proposed that the faster the speed, the slower time will be.
If the speed reaches the speed of light, then time will stop, and if the speed exceeds the speed of light, the past will be seen. " "I know this."
Hu Gang nodded repeatedly: "I have heard of this theory, and many science fiction novels, including movies, have also used this theory.
According to Einstein, as long as people can exceed the speed of light, they can Isn’t time travel?”
"Almost, but real time travel is impossible."
Wan Changchun corrected him with a smile.
Seeing Hu Gang being stunned, he explained: "Time is actually a dimension, and real time travel is impossible.
There is a saying in philosophy that one cannot step into the same river twice, which is enough to prove the fallacy of time travel.”
"A person can't step into the same river twice, right?
How is this possible?"
Hu Gang was confused by Wan Changchun.
Lin Dong smiled and took the initiative to take over, briefly explaining the meaning of this sentence, In fact, the reason is very simple, because rivers are flowing.
When you step into a river for the second time, although it looks like a river on the surface, it is actually a river.
At the moment when the river flows, the river has changed.
The river at this time and the river afterward cannot be exactly the same.
The same is true for time.
People often use the long river of time to describe the passage of time, and this adjective also proves that time The characteristic is that it flows forward like a river, the difference is only in the speed of the flow.
Wan Changchun nodded slightly.
Lin Dong's explanation was very clear.
Seeing that Hu Gang had understood the meaning of this sentence, he continued: "The same is true for time, and time is relative in dimensional space.
According to Einstein's theory For example, when you are flying at the speed of light.
Time will stagnate, but in fact, from a narrow perspective, time is still passing for you, but this passage has changed due to the breakthrough of dimensions.
Compared with people in normal dimensions, time is normal.
Only when they correspond to each other will the results span time.”
"I seem to understand a little bit."
After hearing this, Hu Gang's face showed an expression of sudden realization.
He tried: "Wan Lao, you mean the reason why you and my father have been missing from the Earth base for nearly 40 years.
Time, in fact, these 40 years are just a change of time for you, or you were in a special environment where time stopped, but the time outside was normal, so this result occurred, right?

" Wan Changchun, Lin Dong and Mr.
Youtian laughed at the same time when they heard this sentence.
Mr.
Tian nodded and said with a smile: "Okay, Xiao Hu.
I didn't expect that you still have some understanding.
Your guess is generally good, but in our opinion it is more accurate."
It should be that Wan Lao and your father were in a higher place than our normal three-dimensional space.
In dimensional space, because this is the only way, the time axis will change unpredictably in high-dimensional space.
In this case, it can also cause results that span decades in an instant.
Of course, we are just guessing at this point.
But from the current point of view, the possibility of this guess being true is very high.”
"Yes.
I think this may be almost true."
Lin Dong interjected: "Xiao Su obtained the basic authority of the Earth base through the Pluto base, and Xiao Su has confirmed that the Earth base of the Lant civilization has high-dimensional strike capabilities .
This is enough to prove that the Lant civilization has mastered this earth-shattering technology, and only in this way can the experiences of Comrade Wan Lao and Hu Zhijun be reasonably explained.
In addition, Xiao Su's experience inside the earth base may also be related to high-dimensional technology. ” Wan Changchun and Mr.
Tian nodded slightly, indicating that they agreed with Lin Dong's hypothesis and even attached great importance to high-dimensional technology.
The expressions of the three of them were all filled with extreme excitement and expectation.
Wan Yi doesn't quite understand, and Hu Gang doesn't understand even more.
The importance that the three old men attach to high-dimensional technology is definitely not just that on the surface.
It can be said that at this moment, the three old men are extremely looking forward to obtaining the secret of high-dimensional technology.
As one of the top scientists on the planet, whether it is Wan Changchun, Lin Dong or Tian Lao, they all know the value of high-dimensional technology compared with ordinary technology.
High-dimensional technology has surpassed the scope of ordinary technology.
This technology has even surpassed the imagination of humans, including ordinary cosmic civilizations, and has reached god-like heights.
Once we master the mysteries of high dimensions, humans will no longer be afraid of any cosmic civilization, and no cosmic civilization will be able to pose a threat to humans.
Even if the daily technology of the earth's civilization remains at its current level, as long as we have this technology, even if the Gaians come back again, the earth's civilization will easily defeat them.
The power of high-dimensional technology is indescribable.
After mastering high-dimensional technology, the spacecraft can freely travel through various dimensions, and even easily throw bombs and other weapons directly into the opponent's spacecraft through the advantage of the dimension and then detonate.
From this point of view, not to mention the Gaians, even more powerful civilizations cannot resist.
Just imagine, when you can't find the other party at all, but the other party can easily discover your location, and even detonate vital parts of your ship through your ship's defense.
This kind of war has gone beyond ordinary war, or it is no longer a war at all.
This is a blow from gods to mortals, and mortals have no power to fight back.
In addition, after mastering the mysteries of higher dimensions, the length of life is no longer an obstacle to humans.
For humans, time is just a dimension.
On the one hand, so eternal life becomes part of reality.
Although Wan Changchun was in good spirits and in much better health than the injured Hu Zhijun, he was older after all.
After a heated discussion and understanding of the situation just a few hours ago, his demeanor gradually showed signs of fatigue.
The days ahead are long, don’t be in a hurry.
Under Lin Dong's dissuasion, Wan Changchun finally accepted their arrangement and went to rest.
In the next few days, Hu Zhijun's injuries gradually healed under careful care.
Mr.
Tian arranged for Hu Gang to accompany Hu Zhijun more to fulfill his son's filial piety.
However, due to the arrival of him and Lin Dong at the desert base, the natural base's main authority Mr.
Tian took over, and after a few days, when reinforcements from the northwest base arrived one after another, Mr.
Tian arranged them outside the Earth base to prevent accidents.

Su Yichen and Luo Yan, including the Earth Space Fleet's squadron, were already on their way back to Earth from Pluto.
The sudden retreat of the Gaians, although it saved the Earth's civilization from catastrophe, also marked the beginning of this invasion war of alien civilization.
A full stop.
However, the departure of the Gaians has caused the entire earth's power to fall into a vacuum.
The government of the earth, or the pseudo-government of the earth organized by the Gaians, first operated according to inertia for some time after their Gaian masters disappeared inexplicably. , but as time passed, humans on earth finally discovered that the Sword of Damocles that had been hanging above their heads had disappeared.
Not only that, the disappearance of Raymond Anthony also played a certain catalytic role.
Everyone's shock, confusion and suspicion gradually turned into surprise and excitement, and another chaos started.
Human greed and yearning for power have never been eradicated from ancient times to the present.
When the pressure above disappears in an instant, these things that emerge from the bottom of the heart will soon expand.
A few days later, the entire earth was in chaos, and various forces emerged overnight.
Whether it was the resistance forces at that time, the capitulationists, or even officials of the earth's puppet government, in order to protect their lives, rights, wealth, and future, they launched After a series of brutal battles, the war that had just ended has ignited again in various countries on the earth, and it has become more and more intense, almost spreading to the whole world.
The three major countries that have never surrendered from the beginning to the end, China, the United States, and Russia, are better off.
At least these three countries still maintain a certain degree of military power.
Coupled with the legitimacy and authority of the government, they have temporarily suppressed the Unrest in parts of the country.
But for areas that cannot be suppressed by all forces, no matter which country among the three countries, even the U.S. government.
Due to the sacrifices of all the presidents and senior government officials, the current committee is nothing more than a temporary organization.
Where did some inactive congresses hide in the past?
After the war, many politicians couldn't wait to jump out, trying to use legal permission, including using force, to fight for legitimate leadership.
Under such circumstances, the only remaining Earth Space Fleet squadron is a force that can determine the future destiny of the Earth.
The top leaders of China, the United States, and Russia have reached a private agreement that all parties must first control and maintain their respective spheres of influence.
Then wait for the fleet to return, because everyone knows that when this fleet returns to Earth, this overwhelming global force can restore true peace to the Earth. s: A two-in-one chapter is presented.
