In the testing hall.

"Li Yanyang is more emotional!" someone said.

"He cried!" Ms. Zou said.

Ning Qianxun also saw it, looking at the teary-eyed face, she knew that it was not scary.

What the hell happened to him? Did he see something strange, or did he hear something strange?

It's a pity that they didn't dare to ask, as long as Li Yanyang is healthy.

After the death of his mother, Li Yanyang had dreamed countless times, but it was very vague, and when he woke up, there were dry tears in the corners of his eyes, but he forgot the scene in the dream.

He hoped countless times that he could write down his dreams, so that he could also miss them, but everything backfired.

I never thought that I would really see my mother again, it was still so real, hearing her kind call, seeing her gentle appearance, my whole heart melted.

Forgetting how this dreamlike scene happened, he just wanted to talk to his mother and communicate with her.

So, the mother and son who have been separated for nearly 20 years began to complain to each other, Li Yanyang misses her mother, but the intensity is too far from her mother, because her mother is lonely, lonely floating into this universe, facing eternal, boundless darkness, you can imagine how painful it is.

When she first floated up, she was scared, frightened, she was thinking, it turns out that there really is a soul, maybe there will be heaven and hell!

Will you go to heaven or hell?

She didn't know that she didn't want to leave at the beginning, but her body didn't obey the call, and she could only be pulled by an invisible force.

Until now, she doesn't know if there is heaven and hell, because the road is so long that she knows that she can't reach the end, because she is getting bigger and more vague.

Listening to his mother tell about this strange feeling, Li Yanyang's heart ached, however, he couldn't do anything.

Feeling her son's pain, Liu Damei said: "Don't worry about Yaoyang, it's okay, my mother saw that many people dispersed in the end, it wouldn't be very painful, it just spread like smoke, and then it was gone." ”

Li Yanyang's heart was tight again, he missed his mother, I don't want you to disperse, but after all, there is nothing he can do.

"Li Yanyang, count down to ten minutes, prepare for the second propulsion, and get out of the earth's orbit!"

Li Yanyang suddenly panicked: "No!

Everyone in the monitoring room frowned.

"Why?" asked Zou Jing.

"No, why, listen to me!" Li Yanyang was reluctant to part with his mother.

"No, I can't listen to you for no reason, all the supplies carried by the asterisk must be carefully calculated, and if you stay in the Earth's orbit for one more minute, you will consume an extra supply!" Zou Jing emphasized the seriousness of the problem.

"Good boy, let's go, mom can't follow you for too long, it's very tiring!" Liu Damei was worried about her son's safety, and she also heard that this flight seemed to be very difficult.

"No, I'm going to stay with you for a while!" Li Yanyang said to her mother in her heart.

"Don't, obedient, follow your spaceship, mom is very tired, and besides, we have to keep drifting outward, although this speed seems to you to be very slow, but there is still this force to pull, now next to you, I need a lot of effort. Let's go, mom is tired too, and when you come back, mom will come to see you again!" Liu Damei said.

Li Yanyang felt that what her mother said seemed to be true, so she had to nod: "You must come to see me!"

A kind smile appeared on Liu Damei's blurred face: "Good boy, mom has never lied to you, don't worry, mom is waiting for you to come back!"

Smiling and waving his hand: "Goodbye, child!"

"Mom!"

Li Yanyang screamed in horror, and then, the face disappeared out of the window.

There was an exclamation, which frightened everyone in the monitoring room.

Mother?

All of them are a little blindsided.

Ning Qianxun shuddered, because she knew that Li Yanyang's mother had died!

"Li Yanyang, don't fantasize! It's about to advance twice, keep your attention!" Ning Qianxun shouted.

Li Yanyang looked at the window stupidly, it was pitch black outside, and there was no familiar face.

Although it seemed that nothing had appeared there, he was sure at the moment that it was not a hallucination!

Even if people can imagine it, they will not have such a realistic picture.

Li Yanyang didn't respond to Ning Qianxun, but was just preparing to control the equipment.

……

"One minute countdown, ready!"

"Ready!" Li Yanyang replied.

The crowd breathed a sigh of relief.

"Fifty seconds!"

"Forty seconds!"

"Thirty seconds!"

"Twenty seconds!"

"Ten... Nine... Eight... Seven..."

When the countdown came to the last second, Li Yanyang's already ready left hand pulled!

An action fell, and there was no obvious change, but Li Yanyang felt that the position of the rocket was adjusting.

"Three, two, one!"

Li Yanyang pressed his right hand!

Call!

With one propulsion, the rocket that adjusted one direction was pushed into the vast universe by a thrust.

"Li Yanyang, as the distance increases, our communication will be delayed indefinitely, and we can only inform you in advance of the future actions, but the specific situation needs to be controlled by yourself, the manual has relevant operations, if there is any problem, ask in advance!"

"Roger!"

……

At this point, the subjective work in the monitoring room is only to monitor the situation of the spacecraft, and the others are only responsible for processing when Li Yanyang sends back information.

There is no time node for this passive waiting process, Li Yanyang stays in the sky for a day, and they have to hold on for a day until Li Yanyang dies or comes back.

The rocket is propulsing, Li Yanyang can only pay careful attention to the situation of the rocket, and on the earth, the launch commander has announced to the world that the second propulsion is successful, and the star is going to Mars, everything is normal!

……

In space, after paying attention to the progress for a while, Li Yanyang found that there was no problem, retracted his thoughts, and began to think about his mother.

The existence of the soul has long been confirmed, because he has seen it.

But this time, it's clearly different.

The mother's soul is there, in this universe, and can know and communicate with itself, which is obviously different from the ghosts encountered on the ground.

Moreover, she was not reincarnated and did not reach heaven and hell, but wandered in this heaven.

Why?

Could it be...... Is that speculation true?

As a metaphysical person, although Li Yanyang has great powers, there are still many things that he has never really understood.

One of them, of course, is the soul.

It's not ancient anymore, and nothing needs to be entirely speculated, but there is a lot of scientific evidence.

After seeing ghosts, he checked many ancient books, but unfortunately, the ancients were vague and did not have a definite answer at all.

He then began to search for scientific information.

He remembered a scientist who claimed to have done experiments to prove the existence of ghosts.

However, Li Yanyang was skeptical about that experiment.

The foreign scientist said that he had conducted a study on people who were dying, and he assumed that there were souls, and then when they died, the spirits would see their bodies, and then the people would press something under them when the experimenters were unconscious.

As someone is rescued, he then asks the experimenter to say what he sees.

It is said that many experimenters have reported that for a moment they felt like they were floating, and then they saw the words written under their bodies.

If this experiment is true, then there is no doubt that the soul does exist.

Now Li Yanyang knows that souls exist, but he doesn't think this experiment is real.

Because in his cognition, the soul is out of the body, except for himself, except for Qin Miao, who has been renewed by his own seven stars, no one else has reached it.

Of course, this does not prove that he can't come back, but he thinks that it is at least difficult.

What intrigued Li Yanyang was the second experiment!

That scientist thinks that human consciousness has weight!

Consciousness, without a doubt, does exist.

But in people's cognition, consciousness is consciousness, just like ideas, it is a nothingness that cannot be seen or touched.

How can there be weight?

But that scientist believes that people have the ability to withstand stress.

Anti-stress, in fact, has two meanings.

For example, a person who weighs ten pounds of something will definitely not be crushed to death, this is anti-pressure, the strength from the body to resist physical pressure.

Also, when people are under pressure, they can withstand it and not collapse, which is also anti-pressure.

Obviously, when the consciousness is strong, the ability of people to resist pressure is also strong.

So, he felt that consciousness had weight.

He then conducted an experiment in which he placed a dying person on a scale with very fine precision.

When the experiment was carried out, he found that the weight was constantly and uniformly decreasing, but the amount was very small. He knew that this meant that the water and other substances in the human body were gradually disappearing with the experimenter's weak breath.

But at the very moment of the experimenter's death, he noticed that the weight was suddenly twenty-one grams less!

It was an intuitive descent, either a slow process, or a sudden drop.

This is known as the twenty-one gram experiment.

This scientist directly concluded that the twenty-one grams that disappeared are the weight of consciousness!

Perhaps, this consciousness is the soul.

When a person dies, the consciousness disappears, the soul leaves the body, and then twenty-one grams are lowered.

Of course, this is not to say that all people's souls are twenty-one grams, but this is a representative.

So, the next question arises, if the consciousness, or the soul, has weight, then why can't it be seen? It can't be seen, it can't be touched, it's very mysterious.

Li Yanyang then explored and discovered a noun dark matter.

Dark matter was first proposed by a man named Captan who proposed in 1922 that the movement of a star system could indirectly infer the possible presence of invisible matter around a star.

In 1933, astrophysicist Zwicky measured the velocity of galaxies in the Comae cluster relative to the cluster using spectral redshifts. Using the potential force theorem, he found that the velocity dispersion of galaxies in a galaxy cluster is too high to be confined to the cluster by the gravitational pull generated by the mass of the visible galaxy in the cluster alone, so there should be a large amount of dark matter in the cluster, which has a mass at least 100 times that of the visible galaxy. However, this conclusion was not taken seriously at the time.

An important evidence for the existence of dark matter comes from Rubin and Ford's study of the rotational speed of stars in the Great Andromeda Nebula in 1970. Using high-precision spectral measurements, they can detect the relationship between the speed and distance of the rotation of peripheral stars around the galaxy far from the region of the galactic nucleus. According to Newton's law of gravitation, if the mass of a galaxy is mainly concentrated in the visible stars in the core region of the galaxy, the velocity of the stars on the outer part of the galaxy will decrease with distance. But observations show that the velocity of the stars on the outer periphery of the galaxy is constant over a considerable area. This means that either Newton was wrong, or, the quality is wrong!

The law of gravitation, everyone uses it very coolly, there is no problem, why doesn't it work?

As a result, it has been speculated that there may be a large amount of invisible matter in galaxies that is not only distributed in the core of the galaxy, but also has a mass much greater than the sum of the masses of the luminous stars.

By now, the existence of dark matter has been generally accepted, and it is believed that there is a lot of dark matter in the universe with super mass.

Since it is dark matter, of course it cannot be seen, it does not reflect the sun's rays, nor does it emit light waves, it cannot be seen, it cannot be touched, like a ghost,

In fact, it is not necessarily that it does not emit light waves, but it may emit something that is not perceptible to human technology.

According to the comprehensive analysis of the existing observational data, the main component of dark matter should not be any microscopic elementary particles that are currently known. Today's particle physics is striving to explore the properties of dark matter particles through a variety of means.

With dark matter, there is also a related term, called dark energy.

Based on various experiments, humans have deduced that the universe of 27 is composed of dark matter, which is like the glue that connects all matter together. Then a study found that some of the dark matter is disappearing, and the reason for their disappearance is dark energy.

Dark energy and dark matter do not absorb, reflect, or radiate light, so humans cannot directly observe it using existing technologies.

Thinking of this, Li Yanyang suddenly had some doorways, although it made sense when he saw it at the time, but he couldn't confirm the fiction between the lines, such as scientific research showed that what scientific research he hadn't personally experienced, and he couldn't understand it, so he could only watch it as science fiction.

But now, after experiencing the previous scene, he found that it fits perfectly!

The soul may be dark matter, because people can't see it! Only when Li Yanyang opens his eyes to heaven! And then the soul is disappearing!

Her mother also said that she was getting bigger, and that it would dissipate over time. He sees the same thing, then, when an object is in a certain volume, and then the area keeps growing, it means that it is in nothingness!

Mother said that she wants to float upward, and there is power to pull her, so isn't this power dark energy?

Dark energy devours dark matter, in fact, it is not devouring, but just tearing dark matter into nothingness!

Dark matter is dragged by dark energy and continues to spread outward until it disappears, which is another theory, the Big Bang theory.

The Big Bang theory holds that the universe has been in a process after the explosion.

Now all the energy in the universe is produced by explosive radiation, and in fact, this energy is constantly decreasing until the end of the explosion process.

To put it simply, in the case of a grenade, its explosion may be just a second, suddenly light up, and then extinguish.

The missile explodes, which may last for ten seconds, and one can see a large fireball suddenly explode and then gradually extinguish.

And the atomic bomb, of course, the duration of the explosion is longer, and the energy emitted is also high.

Then keep zooming in, imagine the universe as a big bomb, and when it suddenly explodes, the duration may be hundreds of millions of years!

It's hard to imagine that the explosion would have lasted so long, and in the process of this explosion, there are still living creatures that are born, and civilizations will develop!

In this way, the earth is like a dust inside after the explosion of a grenade, and on this dust there is the sea, and there are living things, multiplying......

However, one day, the explosion will be completed, and the energy and light and heat generated by the explosion will disappear, and then, the universe will be nothing.

One of the bases that underpins the Big Bang theory is that people have discovered that the distances between the planets are getting farther and the universe is expanding!

Why is it inflated? Where does the power come from?

If it explodes, of course, it will keep getting bigger.

The grenade was the size of a fist, but after it exploded, it collapsed.

Therefore, the scientific community generally agrees on the Big Bang theory, and the increase in the distance between the planets is also caused by the force generated after the explosion, but people have not found this force and cannot detect it!

What is it? dark energy!

Although Li Yanyang couldn't do experiments to show it, after going through all this, he felt that it should be like this!

The universe is expanding, everything is expanding.

Therefore, the dark matter of the soul will float upwards after leaving the body, and under the traction of dark energy, it will continue to float upwards until this substance disappears!

Everything will disappear, except that the dark matter seems to be a smaller speck of dust after the explosion, and it will dissipate faster.

Of course, the soul is dark matter, it does not mean that dark matter is the soul, the soul can still resist this dark energy in the human body, but it will not work after leaving the body, so it will accelerate its dissipation.

Li Yanyang also finally understood why his heavenly eye could see things that others could not see, perhaps, it was just that the wavelength bands that could be recognized by opening the heavenly eye were different, such as the sound heard by human beings, which could only be heard in a continuous way, and ultrasound could not be heard.

But the fact is that ultrasound exists.

It can only be heard with the help of instruments.

Obviously, his celestial eye is equivalent to adding an instrument to his eye, and then allowing him to see dark matter that humans can't recognize!

Li Yanyang suddenly wanted to open the eye of heaven to see how much dark matter existed in this vast universe, but he didn't do it.

First, he was really afraid that as soon as he opened his eyes to heaven, he would be in hell, surrounded by ghosts!

That's eerie.

Of course, the main reason is that he can't use his ability indiscriminately, when he beat away the uncle who should be called uncle, he was subconsciously afraid, and he looked at his mother because he missed him, and now, he can't consume his energy because of curiosity.

This is not the earth, there is no inexhaustible oxygen.

True Qi consumption is to be replenished, replenishment is to practice, practice is to overbreathe, and breathing consumes oxygen.

And now, oxygen is rationed, and consuming a little less, a little less, means that you are less likely to come back.

He still has to come back, he has to watch Xuanhuang grow up, and he has to reunite with his mother again.
