Einstein's equation is written on the blackboard:

r_uv-1/2*r*g_uv=k*t_uv(rμν-(1/2)gμνr=8gπtμν/(c*c*c*c)-gμν)

"Eisstein's gravitational field equation can be summarized in one sentence. Matter tells space-time how to bend, and space-time tells how to move matter. The left side of the equation written by the teacher represents the distortion of space-time, and the right side represents matter and its motion."

"Very good." Xu Haiying nodded approvingly, "Any mass object will cause space-time to bend, and then the objects continue to make their inertial motion in this curved space-time. This is the core idea of ​​Einstein's general theory of relativity. Student Ye, Do you know black holes and wormholes?"

"If the two bends are suddenly connected, a wormhole will be created. If the bend is too strong, even light falling in and unable to escape, it is a black hole in the universe."

Seeing his classmates looking at him expectantly, he continued: “Wormholes that continue to appear and disappear on the micro-scale can only allow elementary particles to pass through. To create a macro-scale wormhole, negative energy is required. As for negative energy, Hawking is in It is mentioned in the black hole radiation theory that when a particle-antiparticle is born at the edge of a black hole, one of the particles has enough energy to escape from the black hole, while the other is sucked into the black hole. The particle in the black hole is based on energy. The law of conservation has negative energy."

Most of the students heard what Ye Xueqiao said. Xu Haiying, who originally just wanted to talk about the theory of relativity, did not expect Ye Xueqiao to know so much. She said, "Do you think this is achievable?"

"Our current science and technology cannot separate positive energy from negative energy. Stripping negative energy violates the second law of thermodynamics. So, for now, traveling through time and space is still a human dream."

"Very good, please sit down!" Xu Haiying probably knew Ye Xueqiao's learning situation in her heart. She smiled and said, "Physics is not as boring as everyone thinks. If you study with interest, you will gain a lot of interesting things. Knowledge. Is everyone awake now? We will go to class when we wake up!"

Ye Xueqiao's serious appearance was unexpectedly attractive, clear-cut and clear-cut. The expression in Qi Muyun's eyes watching Ye Xueqiao became more and more unbelievable.

Is this still his ignorant and ambitious wife?

The students in the first class were also shocked. The poor students who had the lowest grades in the freshman year suddenly talked about the theory of relativity in class. The impact is no less than that of Mars hitting the earth.

"Good boy, you are this!" After the class, Xiong Lu gave Ye Xueqiao a thumbs up, "But, what kind of abstract concept you are talking about, I still don't understand the little slider."

"If you don't understand the little slider, I will tell you."

After finishing talking, he randomly found a question and started drawing a small slider for Xiong Lu.

"Gravity, supporting force, friction... Mark it first."

Physics is a highly polarized subject. Some students can solve problems by intuition even without learning, and many students have been unable to understand abstract concepts in physics.

Xiong Lu has been on the verge of failing in physics since he entered high school, but he is good at both Chinese and English, other subjects are mediocre, and his overall score is a little higher than Ye Xueqiao.

In this key high school, academic performance has allowed students to form a food chain-like relationship. There are not many students who study well and are patient to lecturing to others. There are even some jealous students who do not perform well in one test. I can cut off contact with my friends.

Xiong Lu listened to Ye Xueqiao whispering and tirelessly lecturing to him, and he was suddenly moved.

"Do you understand?" Ye Xueqiao said, "If you do a few more exercises with the same questions, you will definitely take the exam."

"I understand!"

Ye Xueqiao pursed her lips and smiled: "What do you know, can you tell me again?"

"I understand that you are a potential stock." Xiong Lu finally has the real sense that Ye Xueqiao is a physics contest student. If you get the second grade, you just need to pass the first line of college entrance examination. Our province’s provincial No. 1 also has the opportunity to lower the score of college entrance examination!"

"Yo, you know a lot."

"However, if you take the road of competition, you will also have to study physics when you go to university. What do you want to study in the future?"

"Well... If I can pass the exam, I will apply for astronomy."

"Astronomy? Studying the planet, right? That's great." Xiong Lu's eyes flashed, "Son, Dad thinks you are definitely promising."

"Dad also thinks you can make a big splash."

Ye Xueqiao’s eyelashes are very thick, and the corners of her eyes are slightly downward. It can make people’s heart beat faster when looking directly at people. Suddenly, Xiong Lu was caught by Ye Xueqiao’s eyes. He grinned and rubbed Ye Xueqiao’s ears and said, “It’s so cute, worthy of being a dad. Look at the good rabbits that grew up."

Wu Zixuan saw that Ye Xueqiao was very good at talking, and he also came to chat up: "Xueqiao, how did you progress so fast? Did you deliberately pretend to be a scumbag in your freshman year?"

Ye Xueqiao said: "I am a real scumbag, with a serious subject, science is better, and liberal arts are too lax."

"Then please tell me something, next time you teach Xiong Lu a physics problem, please take me one. I just listened to it. It's really easy to understand, and you are more patient than I am at the same table."

"Well, no problem."

Ye Xueqiao really didn't feel how patient he was, his character was very easy-going. If others don't offend him, he won't make trouble.

When Fang Ran saw Wu Zixuan's admiring gaze towards Ye Xueqiao, his heart became sour again, and he was not angry.

She whispered to Wu Zixuan: "He said that he can understand those by just turning through a few popular science books, and only knowing the theory is useless. The test score is the key. You can ask me if you have any questions."

Wu Zixuan replied to Fang Ran in a low voice: "Last time I asked you that you were very impatient, and you can definitely hear you at this volume, you don't have to say that."

"Hey, yes, I heard it." Xiong Lu looked back and said, "Fang Xueba, we all know that you passed the forty-seventh grade in the last exam. You don't need to always boast euphemistically, okay? ?"

"You're just bragging!" Fang Ran said, "I'm very low-key, alright."

"Is it okay to recognize your own mentality? Don't stare at other people's every move all day, it's really boring."

Fang Ran wanted to be praised and embarrassed, arrogant and inferior, his heart was higher than the sky, and he felt that there was nothing in the world that she couldn't get.

Angrily, she stuffed the textbook into the hole of the table, turned her head to the last row to talk to Qi Muyun, trying to prove that she was still attractive.

Xu Mingcheng and Qi Muyun surrounded a few boys. They were happily asking Xu Mingcheng to explain the theory of relativity in a popular way. Xu Mingcheng said in a bit annoyed manner: "How do you call it popular?"

"Just don't say so abstract, you say something that people can understand."

Qi Muyun, who hadn’t said a word until now, picked up a pen and said, “If this pen is space-time, the length of the pen is fixed, and there will be projections on both the time and space planes. When the pen is vertical, the projections are all projected. On the time plane, there is no projection on the space plane. This means that the object is stationary and time passes at the fastest speed. On the contrary, the object is moving at the speed of light and time is stationary."

"Wow, you deserve to be a great god."

"I understand this time."

"Speaking of which, today's Ye Xueqiao really surprised me, he seems to be a tyrant."

"Like a school bully? What if someone is really a school bully."

"How is it possible? He learned science fiction! You don't know what his grades in the first year of high school are. I don't care if he is a schoolmaster. Omega is so beautiful that he can give birth to children."

"Gou San, why did you make the topic suddenly stray?!"

"Hahahahaha! Gou San is right, how well can an omega learn physics competition? Science is the world of alpha."

These alphas talked about Ye Xueqiao's sudden decrease in voice, but his eyes couldn't hide his excitement. Rabbit omega is not rare, but such beautiful ones are rare.

But they said nothing.

In the first year of high school, there was a tall black bear Alpha who wanted to do something against Ye Xueqiao. He was beaten by Ye Xueqiao and Xiong Lu with a sack. After that, the reputation of Tuqiao Renmei Luziye spread, and few people offended him. he.

Qi Muyun naturally knew what was in his mind for alpha at this age. He frowned and felt a little uncomfortable in his heart.

Ye Xueqiao, that's his rabbit, his omega, his fiancee, can that be for other people to think about?

"Subjects need to be divided into gender? There are many omegas who are good in mathematics, physics and chemistry." Qi Muyun said, "How old do you want to let omega have children?"

Qi Muyun seldom held a bargain with everyone at ordinary times. As soon as he spoke, several alphas stopped talking.

The atmosphere was embarrassing, but Fang Ran quickly ran to Qi Muyun at this stall.

She seemed to brave a little red heart around her body, and regardless of the atmosphere, she said directly: "God Qi, do you like physics? I like physics too!"

She showed her kindness to Qi Muyun in every possible way when she started school. Everyone knew her thoughts, including Qi Muyun.

Speaking of physics, Qi Muyun's eyes suddenly changed, and he looked at Ye Xueqiao by the window again.

A gust of wind blew the screen by the window, and the snow-white little rabbit was talking to the same table with his eyes bent.

Fang Ran finally understood this time that Qi Muyun was not looking at her, but at Ye Xueqiao.

She stood awkwardly on the spot, and after a few seconds, she returned to her seat in a desperate manner.

"Qi Muyun is looking at you again. He has seen you several times today." Xiong Lu lay on the table and played with a pen, "He is really interesting."

"Don't you say that I almost forgot him." Ye Xueqiao was a little sleepy, he rubbed his eyes, "I have to find him tonight, and tell you a secret."

Xiong Lu took a sip of grape juice and leaned over to listen. Ye Xueqiao lay next to Xiong Lu's ears and whispered in a volume that only two people could hear: "He is the fiancé appointed by my biological mother. I have to talk to him about the cancellation of the marriage contract tonight. "

"puff-"

Xiong Lu was like a sprinkler, and the slimy grape juice sprayed the tabby cat Omega in front of him.

The tabby cat hates all kinds of liquids the most. He looked back at Xiong Lu and shouted: "Just crispy noodles! What are you doing!"

"I'm sorry, I'm sorry, I'm sorry." Xiong Lu apologized sincerely, "Excuse me."

The tabby cat took the paper handkerchief that Ye Xueqiao handed over. Tsundere turned her head, and the wind also turned her head to recite English words.

Xiong Lu calmed down and said silently to Ye Xueqiao: Are you kidding me? !
