It's March of the new year. In this spring, which will eventually become a part of the memory, Dome has ended this Friday day.

This week, starting on Monday, it had been five full days since Dome had set foot in his own house, and he had not had any contact with his family. But don't be mistaken because of this, she's not the kind of girl who is in the middle of nowhere.

During these five days, the only place she went was Tokiwadai Junior High School. In order to avoid distractions, she spent five days living in a makeshift dormitory in the Garden of the School in a life of almost complete isolation from the outside world, even handing over her mobile phone to her teacher. This is because she has an important entrance exam to take.

Today is the last day of the entrance exam. Just an hour ago, she had just finished her last exam.

The way of this exam is very special, and it is actually a separate written test with only one person. The subjects of the examination are 10 physics and 2 mathematics. For girls of this age, just taking this form of exam will probably be too nervous. But Dome had already passed the last day of the exam naturally. It's not because of how good she is psychologically, it's just that she has a little secret (which is somewhat unfair from an exam perspective). But there is no way to evaluate this kind of inexplicable thing).

Although the exam process was not affected by his mentality, Qiongno's mood was not too good. Because when she got the exam papers, she found that there was something wrong with the way she prepared for the exam. Although the results have not yet been released, she feels that the results of the exam have not met her expectations, which makes her quite dissatisfied.

She was tidying up in the dormitory when a staff member at Tokiwadai stopped her. This came as a surprise to her, as she had heard that after all the exams had been completed, students should not normally be in the Lodge until the results were in, and it was purely out of confidentiality.

"Miss Kaihara, please go to Tokiwadai again, there is still a test to be completed."

"Now?"

"Yes, we forgot to inform you just now. There is also an aptitude test. It doesn't have to be today, but it won't be until at least next Monday. It is a hassle to re-apply for an entry permit. ”

The dome was a little confused. Today is not a public test day, so it must be the school's own test. The results of aptitude tests at prestigious schools such as Tokiwadai are even authoritative, and you can log directly into the official library.

However, in general, the aptitude test of such schools is conducted after the start of the school year and the list of students is determined. Even if you don't think about time, I'm still a very good student.

Despite his doubts, Dome and the staff went to the test site set up in the Tokiwadai playground.

The floor of the playground is paved with special optical fibers, which are able to display the required graphics, on the same principle as the sandbags with light signals used by his brother for training – more precisely, the civilian version of the technology used in the playground today. There were also cubes of various sizes marked with various weights on the floor, which was clearly the centerpiece of the test.

"Miss Kaihara's ability is LV.3's gravity control, right? Can you express what you think best represents this ability? ”

The testers present were unusually polite, probably knowing that they were the granddaughter of the chairman, which Qiong Nai didn't like at all. Of course, even older than many of the staff members present, she would not be so nervous as to express her feelings so bluntly.

The so-called gravity control, as long as you listen to the name, you can know what kind of ability it is, and the dome has long mastered this ability. However, in the process of preparing for this exam, she discovers the truth behind the appearance of her ability to control gravity.

Dome opened her hands as if she wanted to embrace something. Her move left everyone present confused. But then, all the testers were stunned.

Because the dome threw itself into the boundless blue sky.

If the level of gravity control is high enough, it is not impossible to make yourself float, but this is not the case with the dome.

She flipped her body, changed direction at will, and flew through the sky without any restraints.

Yes, she is not floating, but flying.

"The value of the AIM diffusion field rises, a change in the gravitational field is detected, and the correction begins."

"The numerical correction is completed, the curvature is confirmed, and the redshift value is measured......"

On the ground, testers are busy. The instrument had clearly told them that the information they had was incorrect. At least, it's also incomplete.

That's right, the ability of the Dome is not just to control gravity, but to control gravity at a deeper level. Controlling gravity is just one manifestation of her true abilities.

This is the truth she stumbled upon and was born out of an attempt in the process of learning. But once you think about it, it seems to be taken for granted, after all, gravity itself is a component of gravity. It's just that the blind spot in her thinking has made her never realize this before.

Dome really loves to fly. When she stumbled upon the nature of her abilities, she occasionally tried to fly. At first, she didn't notice anything, but when being in the sky became a controllable normal, she found herself caught by the sky. So when the testers asked her to show what she thought would best show her abilities, she didn't hesitate to fly.

Since ancient times, flying has been one of the greatest dreams of mankind. Because what stands in the way of humanity's dream of flying will be the earth on which humanity depends.

Gravity is a characteristic of the mass of the planet, so isn't flying in some ways the same as being the enemy of the world?

Putting aside these overly philosophical topics for the time being.,Even in the school city that is famous for its superpower development,,Unlimited flying ability is quite rare.。 This is because controlling gravity is essentially an almost impossible task. Although gravity can be countered by means of thrust and lift, the essence of gravity as a manifestation of mass remains the same.

Therefore, when the testers present discovered that the way the Dome flew was actually the manipulation of gravity, everyone realized the value of this girl.

"Hey! Look there! What is that? ”

The students on the ground were shouting.

The figure flying freely in the sky naturally attracted the envious eyes of countless students.

Dome, who doesn't like to be noticed in this way, began to land, but there were already a lot of people gathered on the playground.

"So, it should be fine, right?"

Finding that the crowd was getting more and more crowded, she tried to end the test as quickly as possible. It was at this moment that the synthesized electronic sound kicked in.

"Comprehensive assessment LV.4."

Unlike normal scoring, there is no fixed metric for judging gravitational manipulation. The current test method can only be evaluated by the specific details of the curvature change through the same conversion. However, there is no question of whether this is true or not, everything has detailed controllable values. If you need specific test data and evaluation formulas, you can even ask for them and calculate them yourself.

"Congratulations, Miss Kaihara. Please wait a moment and we will update your ID details. ”

"Really? Thank you. ”

Dome said briefly but politely.

From LV.3 to LV.4, it felt like nothing had happened. Dome didn't know what it was like for others to get their level up, but at least he just seemed to have figured something out of the blue.

Seriously, she was a little confused about that. Although it can be explained physically, it is even more mathematically impeccable.

Simply swipe the ID card at the login point, and the new information has been entered into the library. From this moment on, the scholarship amount will also be calculated according to the new criteria.

But in fact, there is one thing that Dome doesn't know, that is, at the same time, all the information platforms of Tokiwadai have logged in her information synchronously. And in all the teachers connected to the Internet, a prompt appeared.

This is a special feature of the Tokiwadai Teacher Information Platform. Teachers will be notified as soon as a student improves their abilities, so that the development curriculum can be modified according to the specific situation.

There is still an incomprehensible element here, which is why Dome is on the list of students? At least for now, she's not a very good student.

In the teacher platform, Tokiwadai teachers are also talking about this new news. And the Russians, typing words in front of the computer and having routine quarrels with other teachers, are thinking about a question.

In fact, when he received the prompt message, he couldn't help but be stunned for a moment.

Not because of the increase in the level of Firmament's ability—which he took for granted—but because of the nature of the measured ability.

As someone who knows something, he doesn't take her abilities for granted as much as the ignorant Dome does.

The ability of gravity as a system is not uncommon, but gravity is a different story entirely. In fact,Whether there really is a person who belongs to the gravitational system in the school city,It's likely to be a pretty difficult question to say.。

As an authority on the theory of gravity, in his opinion, a true gravitational ability should measure at least two phenomena during the ability test: 1. It must be able to induce time dilation. 2. Must be able to produce a lens effect.

This is not a fastidious request, but a necessary manifestation determined by the nature of gravity. Without these two expressions, what is gravitational-related ability?

In some ways, it may be that the ability to move in space is closer to the essence of gravity than those who are similar to those who operate with gravity.

This is not surprising. Ever since Hermann Minkowski (Hermann_Minkowski) unified time and space into space-time, and Albert Einstein (Albert_Einstein) curled space-time into gravity, the pair of masters and apprentices who had a bad relationship have linked gravity to space-time.

Prior to the Dome, no one with the ability to manipulate gravity had experienced time dilation in the ability test. So the Russians believe that it is not really gravitational manipulation. Many times he even wondered whether gravity, as described by general relativity, was itself exclusive to superpowers explained by quantum mechanics. After all, at some levels, general relativity and quantum field theory can also be regarded as "mortal enemies" in a sense.

However, this record officially ended today. In the Dome test report, a value appears - the redshift value.

In the gravitational field, the gravitational force of the object causes the frequency to become longer and the energy to decrease, which is also known as the red shift. One of the most direct manifestations of this is the slowing down of time. In other words, gravity dilates time.

It's not that I haven't imagined such a situation, but I never thought that it would be achieved by the dome. It wasn't for any deep reason, but it was hard for him to imagine such a coincidence—he himself was an expert in the theory of gravity, and his student's ability to be found to be the power of gravity (although Qiongno had not yet shown the ability to dominate gravity when he became his student).

He has a bad temper, but his mind is always outstanding. To say that he did not doubt this is obviously self-deception. Although he himself did not want to admit it, this student did have too many situations that were difficult to explain by common sense, as her father (who was also his younger brother) said.

"But in any case, even if there is really any secret, it has nothing to do with her."

Only this is what he can assert.

Uploader's Note:

About Minkowski and Einstein: Few people know that the mathematical tools of Einstein's general theory of relativity came from Minkowski's work. In fact, Minkowski space-time is the fundamental foundation of Einstein's general theory of relativity. But even fewer people know that the pair of mentors and apprentices are almost completely at odds – even though Minkowski space-time is inspired by Einstein's special theory of relativity, and the mathematical tools of general relativity come from Minkowski space-time.

Back at ETH (ETH Zurich), Minkowski once called Einstein a "lazy dog". And Einstein also laughed at Minkowski after he discovered Minkowski's space-time: "Mathematicians just like to do these things, and they make physics so that even physicists can't understand it." ”

Minkowski also has a little story related to the four-color theorem, you can search for it. In fact, I doubt that the student who blatantly embarrassed his teacher was our Albert Einstein – he had a very good motive.
