The introduction of gravity unveils the inner mystery of the movement of the sun, moon and stars. It has become an important cornerstone for human understanding and knowledge of the world. Newton himself used the law of gravitation to explain the tides, planetary precession and other phenomena, Newton's friend Halley used it to predict the return cycle of Halley's comet, and the French astronomer Le Vervier deduced the existence of Neptune from gravity. The estimation of the first, second, and third cosmic speeds, which play an important role in the aerospace industry, also has the law of gravitation.

This is all common knowledge in the scientific community, and it has even become the consensus of mankind around the world, and today someone is here to say that gravity does not exist!

Does this mean that you are better than Newton or smarter than all mankind in the world? Any theory put forward by human beings must be supported by logic, instead of making sensational statements and not coming up with a single scientific argument to defend their own views.

The physics teacher was speechless, and he talked for more than ten minutes in one breath, and Lu Wuji stood there looking at him with a sneer on the corner of his mouth.

"Are you finished, teacher?" Lu Wuji said lightly.

Cheng Xiaolu quietly pulled the corner of his clothes, and Yang Yang and An Wei both looked back at him, and their eyes hinted that he should not face the teacher. They all know that in the cultural atmosphere of China, right and wrong are not important, harmony is the first place, and if you offend people like Lu Wuji, even if you are right, you will not be able to gain a foothold in school. What's more, gravity is universally recognized, and it is really overwhelming for you, a freshman in high school, to overthrow it!

The physics teacher picked up the teacup and took a sip, then put it down heavily, and said proudly: "Even Einstein did not overturn the theory of gravity, but explained gravity in another way." Hey, hey, okay, tell me, how does gravity not exist?"

Lu Wuji knocked Cheng Xiaolu's hand off and began to flip through all the theories about physics and gravitation in his mind.

He did not read from the book like a physics teacher, but tried his best to explain advanced scientific principles in the most popular language.

In fact, Einstein's general theory of relativity has overturned gravity, but the scientific community is unwilling to let the two scientists tear it apart so much, because it is too embarrassing, so it is said that Newton's theory is correct in the first and second cosmic speeds. It fails at the 3rd cosmic velocity. In fact, this is just a matter of secrecy for His Holiness.

We can use the analogy that our space-time is like a flat sheet, if we put a shot put ball in the center of the sheet, the sheet will dent down, and if we put a small ball on the sheet, it will roll in the direction of the big shot put, which seems to be attracted by the big shot put. In fact, the movement of the ball is only due to a depression in the middle of the sheet.

This is what Einstein called space-time bending. So Newton thought that gravity, which was almost ubiquitous, was essentially non-existent.

"Is that how you understand general relativity?" asked the physics teacher.

"So what do you understand, teacher? How many years have you not paid attention to the cutting-edge research of world physics? Teacher, do you think that naked singularities exist? Do you think there is a time arrow and a cosmic microwave background?"

The physics teacher opened his mouth to speak, to tell the truth, he has indeed neglected to study in the past few years, but he thinks that the physics knowledge he has mastered is completely more than enough to teach the first year of high school! It's like going to the supermarket to buy groceries, bringing 100 yuan can meet the needs of lunch, and bringing 1,000 yuan is not for nothing? How do you know that there is still a demonic scumbag like Lu Wuji! No, he is afraid that he can't be called a scumbag no matter what......

The physics teacher suddenly remembered the graceful figure of the history teacher, "Mother, do I have to follow in his footsteps?" The physics teacher's face was a little ugly.

……

After all, Lu Wuji could not thoroughly understand so many physical theories in a short period of time, and in the end he could only read the latest treatises and achievements of the world's physics masters on gravitation, and read them.

However, try to add some mood particles or try to replace the written language with spoken language when reading, so that everyone can listen as if they were speaking it themselves.

It's like a newscaster looking at the screen simulcast, but the audience can't see her reading it, thinking it's an off-script speech.

Finally, we talk about the unified field theory, and this cannot but involve the speculation of scientists on dark matter, and when it comes to dark matter, of course, we will talk about dark energy:

Astrophysicists have proposed an invisible substance that counteracts gravity by squeezing space-time. They call it dark energy. In the most widely accepted model of dark energy, it is a "cosmological constant": the intrinsic properties of space itself make it have a "negative pressure" to drive space. As space expands, more space is created, and with it comes more dark energy.

Based on the observed expansion rate, scientists know that the sum of all dark energy must be more than 70% of the total content of the universe. But no one knows how to go about looking for it. In recent years, the best researchers have done very limited research on where dark energy may be hidden, which has been the subject of research at the frontiers of physics in recent years.

When Lu Wuji read this, he suddenly thought of his star beast devouring system and the power of the dark star that had been advanced through devouring, could this be what scientists call dark matter and dark energy?

But dark matter, or dark energy, seems to be something that scientists have speculated to be possible, and it has not been confirmed and has never been observed, because the so-called 'dark matter' is something that the human eye cannot see.

Could it be that dark matter can combine with human life in the form of a star beast system?

I can't find the answer in the book!

Lu Wuji suddenly stared out the window blankly, and stopped his lecture on the clear logic, vast content, novel theories, and sharp views of physics.

The physics teacher sighed and said, "It's time for me to get out of class...... and then picked up his coat and walked out of the classroom with his head down. stopped at the door, turned his head to Lu Wuji and said: "Lu Wuji, your physics attainments are very high, and the teacher thinks that he can't teach you anymore, but I think that with your age, even if you start studying physics at the age of one, it is impossible to reach such a high level......

Lu Wuji smiled faintly and said, "What I know is nothing more than a drop in the ocean, no more than you, teacher, but during this time, I happened to pay attention to the frontier issues of physics." It's like the little monk of Shaolin Temple took advantage of the old monk's carelessness and hit him with a sudden attack, which actually does not prove that the little monk's kung fu is higher than the old monk's. ”

The physics teacher smiled bitterly: "Thank you for saving face for the teacher, alas, I believe that you have taught you more in this class than I have taught you!"

The physics teacher left, and after a short silence, the students began to talk about it, and asked Lu Wuji for many unsolved mysteries of physics.

Lu Wuji also patiently answered. Among the more than 500,000 books, books on physics and natural sciences account for one-twentieth, which is as many as 20,000 or 30,000 books, basically covering all the contents of physics.

The questions that a freshman can ask are very limited in scope and depth. Lu Wuji flipped through the books in his mind and retrieved the content very quickly, so he almost answered fluently.

The admiration and admiration of his classmates made him very intoxicated, and the role change from a scumbag to a top student did not make him feel that there was anything wrong.

The white fat man An Wei was even more convinced, and wanted to take 10,000 yuan to change seats for Cheng Xiaolu, who directly asked him to roll as far as he could.

Of course, how could An Wei let him be so blind and dare to let Boss Lu's horse leave him and replace him, Cheng Xiaolu's attitude towards Lu Wuji is well known to passers-by, An Wei is just teasing her.

Since An Wei became friends with Lu Wuji, he was no longer bullied in school, and he also accepted a few younger brothers. You must know that before that, he was the angry bag in the school, and everyone could be angry with him if they were in a bad mood.

He even took in two younger brothers, and followed him around the back of his ass all day long, and the boss shouted very attentively.

The so-called residence and qi nourish the body, after being bullied for a long time, people will appear cringe and humble, and after being praised for a long time, they will appear confident and public. The white fat man An Wei is now the same as before, and his spirit has been raised, although he is still as fat as before, it makes people feel that he is not so cumbersome.

This day is Friday, and Yang Yang informed Lu Wuji that he would have a party at Soshi Restaurant tonight at the invitation of the head teacher, Mr. Xu.

Lu Wuji replied, 'I'll see the situation' and left. Yang Yang looked at his back and fell into deep thought.

Teacher Ling stopped Lu Wuji in the parking lot and said that he would use the car to visit a colleague in the western suburbs, and let Lu Wuji take the car home. Lu Wuji had no choice but to give her the key.

"Teacher, can't you send me back first?"

"Get out of here! We've made an appointment to meet in half an hour, where is there time to see you off!"

"This is my car!"

"What's yours and mine, you still owe me more than 60,000 yuan and haven't paid it back, you old scoundrel, go away! Also, did you give the physics teacher another bar today?" Ling Han asked, pointing at his nose.

"What's wrong?"

"What's the matter! English teacher, that is, me, was made into a girlfriend by you, history teacher because you are retiring early, physics teacher is in the teaching and research department today and sighs and blames himself for misleading people's children, all because of you, I think the high pool in Yangcheng is too shallow to hold you...... Look around, they're all staring at us, fuck off, get out of the way!"

After being pushed by Ling Han, Lu Wuji had to leave on foot, and the phone rang as he walked. Take it out and answer:

"Did you go to Building 8 of Emgrand Garden after school, remember to paste the mustache and wrinkles, what did you look like when you used to protect Dandan, and what do you pretend to be now, don't show flaws!"

"Why?"

"You...... Alas, Dandan wants to see her Uncle Bazihu, isn't this person you? Alas, why is this girl so crooked, not like me at all. Hurry up, talk as little as possible when you arrive, and leave as soon as you see each other!" Chen Shengnan sighed, and stopped talking, as if there was something unspeakable
