The Sword of Six Doors Points at the Rivers and Lakes

Chapter 36 Anti-traversal!
"What's the matter? It looks like it's shut down. You're here, watching the fire. I'll come when I go."

Ye Xiuwen gave some instructions, and entered the room with Yue'er, and Yue'er threw the prescription on Ye Xiuwen's face angrily.

"I've already told you, I won't let you go, but you have to go?" Ye Xiuwen said speechlessly.

"Then why didn't you tell me that this is a poisonous prescription? My lord knows some medical principles, and said that ten people will die if they take this medicine."

Yue'er was so angry that she tore off her veil.

Ye Xiuwen looked quietly, but saw that Yue'er often covered her face with a light veil, and her feelings were actually a beauty.

Such a woman is so aloofly beautiful, so glamorously beautiful, so beautiful that people dare not dream about it.

At this time, with a straight face, there is a kind of frosty beauty, which makes me feel pity.

"Hehe, don't be angry, I'll show you something amazing tomorrow!" Ye Xiuwen shook his head and laughed.

"Don't look, I don't believe you anymore, hum!."

Yue'er snorted coldly, a little mischievous in her cold beauty.

Seeing this, Ye Xiuwen shook his head again, thinking: If we want to get along well with this girl, it may take time.

Ye Xiuwen went out of the house and continued to boil the soup. After half an hour, there were only three bowls of soup left in the pot, so Ye Xiuwen stopped the fire.

"Hou San, take all three bowls of soup and one bowl of medicinal soup tonight. You may have some bone pain at night. Be patient for one night, and you will become a warrior tomorrow," Ye Xiuwen said to Hou San.

"Really?" Hou San seemed to be in disbelief.

"If you don't believe me, you don't have to drink it."

Ye Xiuwen's face was sullen, Hou San didn't dare to disobey Ye Xiuwen's intentions, and quickly said: "I drink, I drink..."

In front of Ye Xiuwen, Hou San drank all four bowls of soup, smacked his lips, and said, "Fifth Lord? Why don't I feel anything?"

"Tch, you think it's an elixir? Go back to sleep. We have to set off tomorrow morning to go to the warehouse."

Ye Xiuwen flicked his sleeves and left. He just wanted to go back to his room, but found that the door was locked.

"Go and sleep elsewhere!" Yue'er's voice came from the room.

"I can sleep in the living room, right?" Ye Xiuwen said speechlessly, thinking: This is my room, okay?

"Can't,"

Yue'er said word by word, her attitude was very firm.

Ye Xiuwen was very helpless, he could only lift his feet up to the roof.

The roof is made of wood, with straw on it, lying on it, soft.

Ye Xiuwen looked at the stars while recalling the past of the earth.

Unexpectedly, when he came to this world, four days passed in a flash.

Time flies, but Ye Xiuwen misses his home on earth all the time.

He has not graduated from college for a few years, has not had time to start a family, and has not even bought a house yet, and he is still living in the company's dormitory.

But he still has his parents alive, and it is not easy for his parents to support him in school.Before he had time to repay, unexpectedly, he came to this world.

Ye Xiuwen missed his home on Earth and wanted to go back. He looked at the stars in the sky and searched for his memory.

There is a scientific basis for this kind of thing.

The advent of the theory of relativity tells the story of four-dimensional curved space-time, finite and boundless universe, gravitational waves, gravitational lenses, the theory of the big bang universe, and the main theme of the 21st century - black holes and so on.

All this happened so suddenly that people felt that the theory of relativity was mysterious and unpredictable. Therefore, in the first few years after the theory of relativity came out, some people threatened that "only twelve people in the world understand the theory of relativity".

Some people even say that "there are only two and a half people in the world who understand the theory of relativity".

What's more, the theory of relativity is compared with "spiritualism", "spiritualism" and the like.

In fact, the theory of relativity is not mysterious. It is the most down-to-earth theory, a truth that has been tested thousands of times, and it is not unattainable.

The geometry applied by the theory of relativity is not ordinary Euclidean geometry, but Riemannian geometry.

I believe that many people know non-Euclidean geometry, which is divided into Roche geometry and Leo geometry.

Riemann unified the three geometries from a higher perspective, called Riemannian geometry.In non-Euclidean geometry, there are many strange conclusions.

The sum of the interior angles of a triangle is not 180 degrees, and the ratio of pi is not 3 and so on.Therefore, when it was first introduced, it was ridiculed and considered the most useless theory.It was not appreciated until its application was found in spherical geometry.

If there is no matter in space, space-time is flat, and Euclidean geometry is enough.For example, what is applied in the special theory of relativity is the four-dimensional pseudo-Euclidean space.The reason for adding a 'pseudo' is that there is an imaginary unit i in front of the time coordinate.When matter exists in space, the matter interacts with space-time, causing space-time to bend, which requires the use of non-Euclidean geometry.

The theory of relativity predicted the existence of gravitational waves, found that the gravitational field and gravitational waves both propagate at the speed of light, and denied the action at a distance of the law of universal gravitation.

When light is emitted by a star and encounters a massive celestial body, the light will converge again, that is to say, we can observe the star blocked by the celestial body.Normally, what you see is a ring, called an Einstein ring.

When Einstein applied the field equations to the universe, he discovered that the universe is not stable, it either expands or contracts.

At that time, cosmology believed that the universe was infinite and static, and the stars were also infinite.So he did not hesitate to modify the field equation, added a cosmic term, obtained a stable solution, and proposed a finite and boundless cosmic model.

Soon Hubble discovered the famous Hubble's law and proposed the theory of cosmic expansion.Einstein regretted this and gave up the cosmic term, calling it the biggest mistake of his life.

In subsequent studies, physicists were surprised to find that the universe is not only expanding, it is actually exploding.

And this provides the possibility for human beings to travel through.

Cosmic black holes, space curvature, plus gravitational waves.When these three are combined into one, Ye Xiuwen will have the opportunity to travel back to Earth again!
