Chapter 805

When Weng Lan was in University, he liked to study astronomy and joined the astronomical society.

So when Baichuan Wulong mentioned the word "singularity", some concepts began to flash in her mind.

The term "singularity" is widely interpreted from astrophysics, also known as "spatiotemporal singularity" or "gravitational singularity". It was first proposed by Hawking in 1970. Because the concept is abstract, it is difficult to give a clear definition.

According to the black hole theory, there is a singularity with infinite density and mass in the center of the black hole, so we must define the singularity before we define the black hole.

Using Einstein's rubber membrane analogy, if an object's energy or mass is large enough, it will pierce a hole in the rubber membrane, and this hole can be called a singularity.

Because we have been able to prove the existence of black hole, and determine that the center of black hole is a singularity, so we need to start from black hole to define singularity.

Obviously, light cannot escape from the black hole, which means that the gravitational acceleration and surface escape velocity of the black hole are faster than the speed of light.

The existing theorems regard the matter hitting the singularity as "disappearing". In fact, when the object approaches the singularity, it will be speeded up to the speed of light. According to some existing theories of human beings, it will jump to another space-time if it exceeds the speed of light, so in fact, the singularity is a broken point in the existing space-time. In other words, the singularity should be the entrance of the space-time tunnel. If we can bear the tidal force caused by acceleration, we can go to another space-time from here.

From the perspective of physics,

singularity refers to the point where space-time begins to bend infinitely. Since a singularity exists in the center of a black hole, a singularity may be the starting point of how the universe began since the big bang.

Einstein said that time and space are the illusion of people's understanding. Time is because of the change of everything in the universe, so that people have the concept of time. At the singularity, with the birth of the universe, there began to change, which is the beginning of the universe.

The classical theory of general relativity predicts that there is a singularity, but the existing human theory is invalid, that is to say, quantitative analysis can not be used to describe what is at the singularity.

From the perspective of cosmology, most scientists believe that singularity is the point where the universe was formed by explosion at the beginning of the universe. It has the potential energy of all matter. This potential energy is produced by the big bang and then transformed into the mass and energy of cosmic matter. It can be imagined that singularity is an inconceivable existence without fixed shape and volume.

At the beginning of a world, it should have all the potential energy to form all the matter in the universe, and this potential energy is exactly what human beings call energy. Scientists before the end of the world can imagine that energy is an invisible thing, so singularity should also be invisible. At the same time, scientists can also imagine that at a certain point, the potential energy balance of the singularity of the universe is broken, so by chance, energy is constantly converted into matter, and after several years, our universe, the symbiosis of matter and energy, is formed.

Of course, with human's understanding of the universe, all this is just a deduction. Whether the singularity really exists in the universe is basically inconclusive.

So is the singularity mentioned by Baichuan Wulong the one he knows? Weng LAN has this question in her heart. She can see his side face behind Qin Qicai. She finds that Qin Qicai doesn't seem to understand. So she whispers what she knows to Qin Qicai, hoping to make him know.

Baichuan Wulong is not in a hurry. He moves a chair to one side, and his eyes move back and forth on Weng LAN and Qin Qicai. Basically, he looks at Weng LAN for ten seconds, and then he looks at Qin Qicai for one second.

To tell the truth, Weng LAN gives him a special feeling.

The beauty of this woman is not amazing, but a little touch, her smile can be deeply rooted in the hearts of the people.

Baichuan Wulong, 30 years old, is a post apocalyptic man.

In eschatology, although there are schools in some large gathering places, the courses taught can not be compared with those before eschatology. Astrophysics knowledge will not be taught in schools at all, because it seems meaningless in eschatology. Who cares about things in the universe? In the last world, people are more self-centered and practical.

Therefore, hearing Weng Lan's theory of singularity, Baichuan Wulong is a little surprised. He can't imagine how this woman who seems to be the same age as him knows these things?

After Weng LAN finished what she knew, Baichuan Wulong said with a smile:

"singularity does exist in the universe. Scientists on the sword spirit star, or practitioners of sword God, have studied them.

First of all, people's conjecture that singularity is the gate of time and space is very accurate! It's wrong for them to say that singularity is the starting point of the universe!

I once talked to my parasitic sword God about this.

He thinks that the universe is multi-dimensional overlapping! And every universe has its own shape. For example, there is a universe about one meter in diameter but infinite in length. It actually crosses our galaxy and even passes by the earth. However, we can't see it and have no way to quantify it. However, it really exists in a dimension different from ours and is not bound by our so-called galactic law.Among them, there are many living planets, which may be only the size of a football in our opinion, but the living species on them are tens of thousands of times richer than the earth.

So, are these planets really so small? Naturally, they are not. If they can escape from their dimension and enter the universe in the same orbit as the earth, they may be infinite!

So in different planes, our earth people's cognition of size is collapsing!

A very important link in the concept of multidimensional universe is overlapping. How to say For example, there are innumerable black ink paintings, transparent material scroll randomly spread together, and ultimately we see must be a black, because the innumerable lines of each painting are all overlapped together!

So, if these overlapping pictures constitute what we think of as the universe, the earth is only on one of them, and this picture is actually the universe in our eyes. Because we are in this picture, we can't know what is painted in other pictures. We don't even know their existence!

So what is the singularity? As I have said just now, it is the gate of time and space, which allows objects close to it to shuttle between different cosmic surfaces. That is to say, it is the junction between the universe and the universe, with infinite mass and potential energy!

The concept of earth people thinks that the singularity is at the center of the black hole, which is different from the definition of singularity on the sword spirit star. In the eyes of Jianling star people, singularity is everywhere. For example, in this tent, there are many singularity! They also have infinite mass and potential energy, but because they are connected with other planes, we can't perceive their existence, and they won't exist based on the laws of the galaxy we know!

So if singularity is everywhere, why are we not affected? This is related to the difference of singularities. In fact, on earth, only a few singularities can be used as the gate of time and space for people to walk in the plane universe. It should be noted that the tidal force of the so-called time and space shuttle does not exist. That is to say, fragile creatures like us can also shuttle freely in the time and space tunnel, and the so-called time and space tunnel does not exist Tao also does not exist. When we come into contact with the singularity that allows us to travel through time and space, we may just take one more step forward and reach another plane world. These worlds may be completely different from the earth, or may be a certain period of the earth, such as ancient times, ancient times, etc.

The concept of time is invented by people. In fact, every time point exists in the multidimensional universe. If you can escape from the comfort of the plane, you can really soar in history!

Isn't it amazing? When I heard this from the singularity sword God, I was a little shocked.

Singularity sword God, his way to become a god of sword is to perceive the existence of these singularity!

In the end, he succeeded. He became a God by practicing sword and gained five abilities.

Star battle body, shadow of escape, twisted potential energy, gate of singularity and call of sword spirit!

Star Station is a defensive ability, which can make me have a strong body.

The shadow of escape is a body magic ability, which can make me have a relative acceleration state with the approaching enemy. In other words, no matter how fast the enemy moves, it is useless for me, because my relative acceleration will make me always faster than him!

Distorted potential energy is just my ability to let the old man with white beard explode. I can create a distorted potential energy magnetic field in a local space. When countless kinds of energy potential energy appear in a narrow space, the space will be torn by powerful energy, and there will be nothing in it!

Gate of singularity is a random summoning ability! I can open the tunnel of time and space and summon creatures of different planes. In fact, this ability is weak, because I can't control my summon, and I don't know what I will summon! I once summoned a Warcraft that looked like a wild wolf. It had strong fighting power. It took me one month to rush to a zombie territory and kill all the millions of zombies in it. Later, I didn't know where it went. I also summoned the Pharaoh of ancient Egypt. Hum, that useless guy thought he was in hell, and now he's already crazy! This ability is a bit weak, but it's very interesting! Don't you have four beauties in ancient China? If one day I can summon them out, it can confirm whether the ancient people's aesthetic is the same as today!

Of course, all powers are limited in time and frequency! But even so, I am the strongest! In the years when I became the host of sword God, I have never lost a battle with people

At this point, Baichuan Wulong fixed his eyes on Qin Qicai and said, "well Are you ready now? Is it true that the later I start, the more you know about me, the less confident you will feel? Qin Qicai, I am actually a very kind person, but in the face of enemies, I can become very cold-blooded! Please remember that after I kill you, I will go to destroy the seven sword city! Let your dead soul cry
