There are heroes in every era.

Every era also needs heroes.

It's just that heroes from different eras show different traits, so they have different characteristics.

Heroes in war times make people excited, and in peace times there are heroes who can write epic and touching chapters.

If you narrow your horizons, it is definitely a joyful thing to meet your beloved hero.

Yes, Wang Yufei doesn't have that big ambition.

He never thought about being a hero in everyone's eyes, but it would be nice to be a hero in Lu Yuxin's eyes.

Wang Yufei looked at Lu Yuxin, and just as the girl twisted her neck, a trace of light reflected on her fair face.

At this moment, Wang Yufei felt a dizzy feeling of happiness suddenly coming to his brain.

"You are so beautiful!" Wang Yufei murmured.

"Huh? What did you say?" Lu Yuxin turned her head slightly and looked at Wang Yufei.

The voice was too low and she didn't hear it clearly.

"I said you are so beautiful, as perfect as Euler's equation! Wait, Euler's equation..."

At this moment, Wang Yufei's brain seemed to be hit by something, and a series of equations and countless curves appeared in his mind unconsciously.

Without hesitation, Wang Yufei immediately picked up a pebble on the ground and quickly wrote out the equation in his mind on the ground.

Then I drew complex curves on the side.

Seeing Wang Yufei's sudden madness, Lu Yuxin did not disturb Wang Yufei, nor did she interrupt Wang Yufei's movements. Instead, she silently took out her mobile phone, turned on the video mode, and pointed at the equation Wang Yufei drew casually on the ground.

, and various complex curves.

This process lasted for three full minutes before Wang Yufei dropped the small stone in his hand.

About an entire square meter on the ground has been covered by Wang Yufei's writing.

Lu Yuxin switched out of the video mode, took three photos carefully, and made sure that basically every word could be read clearly. Then she curiously asked Wang Yufei, who was staring blankly at the formula on the ground: "What's this?"

What is it?"

"Remember the abnormal critical point of the Riemann Hypothesis {(1/2)+1} that can be found everywhere? The reason why the Riemann Hypothesis cannot be proven until now is because the infinitesimal error e cannot be

To eliminate it, this is the problem of infinity. Because it is infinite, it cannot be perfect."

Wang Yufei murmured and explained: "But when I saw your appearance just now, I suddenly felt that you were really beautiful, that kind of almost perfect beauty, and then the Euler equation popped up in my mind, followed immediately by

These. What do they look like to you?"

"Is it like a new structure, all the data are entangled with each other, just like these curves, they seem irregular, but if you continue to draw them according to this equation endlessly, the curvature of these curves will cover everything.

If you pick any point among them, you can find another point on the curve that is symmetrical to it."

Lu Yuxin frowned slightly. She didn't fully understand what Wang Yufei was talking about, so she couldn't help but make a confused sound: "Huh?"

"There's something I haven't figured out yet, but do you see this equation?"

Wang Yufei pointed to the second extremely complex equation he wrote.

Lu Yuxin nodded slightly.

Then Wang Yufei said in a very affirmative tone: "It represents that our universe is a perfect sphere!"

Lu Yuxin did not agree or object, she just looked at Wang Yufei quietly.

At this moment, Wang Yufei happened to turn his head and look at her. Their eyes met, which seemed to completely ignite Wang Yufei's inspiration. At that moment, Wang Yufei seemed to see the entire universe in Lu Yuxin's eyes.

"Yes, our universe is a perfect sphere! First of all, we assume that this result is true and introduce the fact that the universe is constantly expanding. Then we can draw a conclusion that every point of this perfect sphere is moving towards the same speed at the same speed.

Expanding outward."

"Then at this time we have to introduce a concept outside the universe. If the previous hypothesis is true, then you think there are two possibilities outside the sphere of the universe, a dead silence of absolute nothingness, or a uniform dense distribution of a single substance

The entire outer space of the universe. The third equation rejects the first possibility."

"That is to say, there is a kind of material in the space outside the universe, so what will happen when our universe continues to expand? There is a fine network at the edge of the universe, so the density of the matter outside the universe will be compressed, and at the same time, part of

The matter in contact with the surface of our universe may change its form and penetrate into our universe, becoming part of our universe."

"This process will continue until the force supporting the expansion of the universe is exhausted, and then enter a short stalemate stage. Then the extraterrestrial matter begins to expand, and our universe begins to gradually shrink. Of course, no one knows how long this process will last.

But these are not the point. The point is, I think there is a limit to numbers, and this limit is the diameter of the universe."

"Numbers larger than this number are meaningless to our universe. Similarly, in the field of negative numbers, negative numbers smaller than this number are meaningless. This number will become larger as the universe expands, and it will also become larger in the future.

Getting smaller as the universe shrinks.”

Hearing this, Lu Yuxin asked her first question: "Why is this number the diameter of the universe and not the volume of the universe? This is not proven."

Wang Yufei turned his head and thought for a while, then replied: "Because assuming that all my previous analysis is true, then our current concept of three-dimensional space is wrong. Space is not divided into three dimensions based on points, lines, planes, and bodies.

It exists in three dimensions like a point, a circle, a circle, and a sphere, so all line segments have a curvature, so all line segments eventually form a circle. The difference is that the smaller the curvature, the larger the circle, and the closer it looks to a straight line at a certain distance!

"

"But no matter how we shrink the curvature, the curvature cannot be zero. This is just like the universe will not become nothingness no matter how much it shrinks in the future. And when the curvature cannot be 0, it also means that π must be an irrational number!"

"This number also needs to delineate the limit of π in order to unify everything. Of course, the most important thing is that the distance between the two farthest points is enough to describe this sphere. For this universe, this number is enough! Bigger

Numbers mean nothing to this universe. They interfere with the unity of the model."

"Wait, that's not it. Well, let's first assume that these are true. Assume that the universe is such a ball, and every point on its spherical surface advances at a uniform speed. Then no matter what happens inside, as long as there is an outward expansion force, the theory

To put it simply, there must be a force to offset it. Just like if we open a wormhole at point a in the universe, then a reverse wormhole will also be generated at point b, which is symmetrical to point a?"

"No, no, it's a little worse, it's a little worse!"

Wang Yufei looked at the formulas on the ground and muttered to himself.
