Road to science and technology

The saying that blessings are unparalleled and misfortunes never come alone refers to Yue Yuanzhou's current situation.

Yue Yuanzhou wanted to build the equipment and go to the Lord God, but he himself ran into trouble.

Since Yue Yuanzhou has nothing except his own carrying function this time, it is equivalent to running naked in the universe. It stands to reason that he can measure the distance from each star to him through observation.

But this requires a period of observation. Science is not about feeling. If you want to accurately measure the distance, Yue Yuanzhou must observe and then collect data for analysis.

This seemed very troublesome, so he chose to use the original star map, which was the star map drawn by the Shenzhou civilization for the exploration of the Milky Way. His whole body was a super microcomputer, so of course he kept these things.

But in fact, the Shenzhou civilization's exploration of the Milky Way was not complete, and it was not even as good as the exploration of the Andromeda Galaxy. Therefore, he encountered some problems when following the star map this time.

He jumped and was almost pulled into the black hole.

This is due to the nature of stellar leapfrog. The distorted space-time near the black hole pulls the target of stellar leapfrog a long way toward it.

Fortunately, Yue Yuanzhou fell outside the black hole's event horizon, otherwise he would have really had to experience a one-day trip to the black hole.

It is true that he himself is protected by the cosmic membrane, but he has never entered a black hole, so naturally he cannot be 100% sure that he is fine.

The event horizon is composed of the radiating point of the scalar polynomial constructed from the Liman curvature tensor and the surrounding space-time. Its boundary is a one-way membrane that can only enter but not exit.

If this is used as the radius of the black hole, the radius of the black hole is about 1.5 astronomical units, which can be said to be a massive black hole.

According to this Schwarzschild radius conversion, its mass is about 100 million times the mass of the sun.

Yue Yuanzhou is now looking at this big black hole from outside the black hole's time interface. The zero point of vacuum allows him to have enough energy to resist the gravitational pull of the black hole. Under the influence of gravity, he is actually moving around the black hole.

There are many kinds of black holes, and they are not all the same. As for the black hole in front of Yue Yuanzhou, it is actually a very slow-rotating black hole. Neither does a black hole jet, because there isn't a lot of material swallowed up by it.

From this point of view, this is actually a hidden black hole. There are many such black holes in the universe and they are also very dangerous. After all, it would not be easy to detect if it were not for the gravitational lensing effect caused by long-term observation.

"It's such a wonderful feeling, these lights can't get out!" Yue Yuanzhou stretched out his hand and looked around, and found that the time and space here were very distorted. If he looked at it normally, he would be distorted now.

And the light in his position can never get out, because the position he is in now is the position of the photon ball.

1.5 times outside the black hole's event horizon is the location of the photon ball. The photon ball is the critical surface of the circular orbit of photons around the black hole. Photons from the outside basically cannot get out after passing through this critical surface. Within this critical surface, only outwardly emitted photons can be emitted. Only photons can get out.

Therefore, photons coming in from the outside world are either swallowed by the black hole, or they continue to circle the black hole at this critical surface under the pull of the black hole's gravity.

This is an ocean of light.

Yue Yuanzhou looked towards the black hole, and photons entered his eyes, which allowed him to see this sea of ​​light.

"Distorted time and space! What a rare opportunity. It's a pity that I didn't bring any equipment." Yue Yuanzhou said in his heart.

The time and space here are extremely distorted. If you observe this black hole from the outside now, you will find that the huge black hole is surrounded by Yue Yuanzhou.

No matter which direction you look in the starry sky outside the black hole, you can see his figure, because he spreads out along the entire black hole's horizon, that is, you can also see the back of the black hole when looking from the front.

So Yue Yuanzhou is now both on this side of the black hole and on the other side.

This way of existence made him feel strange, but it was more of a pull from his soul, which was the effect of strong gravity on him.

"Hey, with this delay, the Lord God must have run away." Yue Yuanzhou sighed inwardly.

According to the information of the Shenzhou civilization, he knew that this kind of black hole was similar to the black hole in Interstellar. It was a massive Kerr black hole. Its slow rotation and distorted space-time made the time here much slower than the outside world.

When he left, he estimated that an unknown number of years had passed in the universe.

Yue Yuanzhou doesn't care anymore. Just leave as long as the main god leaves. Anyway, since you met him for the first time and now you meet him for the second time, you will always meet him again later. Moreover, the main god is very powerful. Even if he goes there with full equipment, he probably won't be able to do anything. other side.

Of course, the other party couldn't help themselves, which was one of the reasons why they couldn't fight before.

What he is a little annoyed now is that he does not have the equipment to explore this type of black hole. This type of black hole has never been encountered by the Shenzhou civilization. It can be said that this is the first time, so what Yue Yuanzhou wants most now is to explore.

Black holes with such a large spin are very rare.

This kind of black hole is related to the Shenzhou civilization's exploration of the concept of time. I couldn't find it before, but now it's coming to my door without looking for it. But I didn't bring any equipment.

According to the physical characteristics, mass, angular momentum, and electric charge of the black hole itself, there are four types of black holes. They are non-rotating and uncharged black holes, non-rotating and charged black holes, rotating and uncharged black holes, and rotating and charged black holes.

These four types of black holes have different space-time structures.

In fact, the Shenzhou civilization did research on black holes, but it was not that in-depth. One of the main reasons was actually caused by Yue Yuanzhou.

His existence gave the Shenzhou civilization a feeling of being the best in the world of technology in time and space. Black holes are nothing more than the product of time and space distortion. The Shenzhou civilization at that time believed that this was not difficult.

And most scientists believe that encountering a black hole is not a big problem. After all, the Shenzhou civilization has space cutting technology and gravitational knot technology. Shielding gravity is as simple as eating and drinking.

But after experiencing failures in neutron star research, scientists realized that gravitational knot technology was not powerful enough. Later, theoretical calculations showed that in order to shield the gravitational force within the event horizon of a black hole, a gravitational knot as precise as Planck space is required.

It was only then that the Shenzhou civilization began to face up to and study black holes.

After a long period of research, the Shenzhou civilization finally determined the correctness of the theoretical classification of black holes.

I don’t know if it’s a coincidence, but this score happens to be divided into four categories, and then four categories again.

The four fundamental forces are four, and even black holes are classified into four categories.

This prompted the Shenzhou civilization to search for black holes in the universe, trying to find the four types of black holes in theory. However, tens of thousands of years later, none of them was found.

This is the kind of black hole Yue Yuanzhou is encountering now.

Why does the Shenzhou civilization want to find four kinds of black holes? That’s because in the scientific community of the Shenzhou civilization, there is a theory about black holes that is often criticized. As long as someone says that they believe in this theory in the field of black hole research, they will basically be criticized by their colleagues. Scoff.

That is, black holes are not singularities.

The black hole is a singularity. This is the understanding of most people, including most scientists of the Shenzhou Civilization. However, there is one person in the Academy of Sciences of the Shenzhou Civilization who has always insisted on the hypothesis that the black hole is not a singularity.

Yue Yuanzhou naturally knew about this theory, and he also encouraged the person who proposed this theory and encouraged him to improve it.

Science needs different voices and different ideas, only in this way can sparks shine brighter.

The same is true for the Shenzhou civilization's research on black holes. It is precisely because of the existence of this theory that the Shenzhou civilization stirred up a frenzy of research on black holes.

This craze has lasted for 30,000 years, even if no such black hole has been found.

Yue Yuanzhou now feels that an unknown secret is right in front of him, but he can't open it to see, which is very uncomfortable.

Although he also knows that the actual situation is that even if the Shenzhou civilization finds all four kinds of black holes, it may not be able to find the truth.

Thinking of this, Yue Yuanzhou couldn't help but think of another way to study black holes. When he thought of this method, he thought of the sacred body of the angel civilization.

"It would be great if we were still in the super god world now. We could throw Kesha Hexi and Yan into the black hole. Maybe we could know what's inside the black hole." Yue Yuanzhou was thinking wildly, and he didn't know that it would not be formed through the dark plane. The black hole, if the sacred body goes in, will it die?

Thinking of this, Yue Yuanzhou secretly wrote down this matter. When the time comes to return to the super-god world, he must find He Xi and ask her to get a few people with divine bodies to experiment. I think the angel civilization will also be very happy.
