My father used to be a physics student, although for some inexplicable reasons, he didn't continue on this path. However, what he had done in this area back then had always been something that Dome was quite curious about.

However, she never thought that the first time she saw her father's paper back then, it would be such an inexplicable content.

How to make the universe?

Anyone who hears this question will probably look at the person asking the question with the eyes of a madman.

Indeed, the amount of energy and mass contained in the universe is far greater than any words can describe, and the mere fact is enough to daunt the question.

However, the question itself may be a pseudo-problem that does not exist. Because, the energy derived from gravity is negative.

This is a math problem for elementary school students, and when the positive and negative values are canceled out, the real surplus will be unimaginably small. Even, it's just the weight of a bottle of power care around us.

This fact seems to tell us that the laws of physics themselves do not limit any man-made creation of the universe at all. This brings up one of the most common assumptions in science fiction: how far an infinitely advanced civilization can go.

The definition of an infinitely advanced civilization is the assumption that this civilization is limited only by the laws of physics. In other words, this hypothetical civilization is both the ceiling of physics applications.

What is very surprising about my father's paper is that it explores the means used by infinitely advanced civilizations to create the universe. However, although the title is quite sensational, when Dome begins to understand the content, it surprisingly begins to feel less strange.

The limits that can be attained by theoretically infinitely advanced civilizations also mean the limits prescribed by physics. In fact, the laws of physics themselves are largely in the form of negation. It is not difficult to understand what the laws of physics prohibit from occurring. You know, the same method has been used in history to cut off the possibility of perpetual motion machines.

Flipping through it, the title is nothing more than sensational, but the content is surprisingly rigorous. After just reading two paragraphs, Dome began to think about the next step along the mind of the paper.

This is a habit of her reading papers. For the most part, she doesn't like to draw conclusions directly from papers. What she likes is that someone tells her what the problem is, then tries to solve the problem herself, and then compares it with the answer (Note 1).

But it's not easy to solve, and you need some other aids. She thought for a moment, knocked on the soundproof glass, and then reached out and pressed the call button to talk to the driver's seat.

"What's the matter? Miss. ”

Mr. Ripper, who was sitting in the passenger seat in front of him, asked.

"Excuse me, but do you have any calculators or paper in the car?"

At first glance, it may sound unlikely, but it makes sense to assume that luxury motorhomes like this are usually used to pick up and drop off bosses and the like who need to run around. I heard that there are quite a few important business contracts signed on the car. So of course, such a situation may be expected in the car.

"There's a preparation in the box on the right, and there's a pen."

Sure enough. Knowing the answer, Qiong Nai easily found what he needed, and it was even better than he had originally thought. Originally, I just wanted an ordinary calculator, but when I opened the storage box, I found that it was a portable personal terminal.

Since it was better than expected, Dome didn't think too much about it. She took off the quill, which was used as a hairpin, pulled open the small simple table in the front row and began to calculate.

The back seat of a beautiful girl in a yukata luxury RV is doing scientific calculations and verifications without distraction, which is also a scene that makes people don't know what to evaluate.

In fact, anyone with a little common sense should think that just this short drive to the location of the fireworks festival will not have time to calculate the answer anyway. It's a pity that the dome itself, as a party, has the bad habit of ignoring some obvious facts once he is too involved.

So when she used a quill to write down numbers and operators one by one, there were things she didn't notice.

At first, it seemed normal. But as she wrote, her writing seemed to become slow.

It's not that the difficulty slows down the calculation, but that her writing has slowed down in the eyes of others.

Except for the two gentlemen in the front driver's seat.

In the eyes of these two gentlemen, what has become unusual may be the concept of "ahead". The sedan they were driving was clearly moving forward, but the signs in front of them seemed to be getting farther and farther away, as if the bridge car was moving backwards; If you look ahead, it seems that the scenery is starting to be dyed blue. Objects that are commonplace under normal conditions have become distorted and messy.

The bridge car continued to move forward in this abnormal scenery, as if it was changing in front of him, and it was just a normal scene.

_

Rustle.

The pure white nib of the quill floats across the same pure white paper, leaving behind a deep purple trail unique to gallic ink. The scenery outside the window also changes with the distortion of the trajectory of the ink, and the vehicles that have already passed are still in the field of vision. The biggest change is the sky that can be seen from here. Because the vast sky is shrinking, following the trajectory of the perspective effect, shrinking into the distance. The roads also lost their color and became pure black and white. Only the division of light and light remains, and the object is brighter in the middle, and the more dim it is at the edges.

All these visions were unknown to the calculating girl.

"Our little lady is really motivated."

Driving the luxury sedan casually on a road full of visions, the driver, Bob Noft, taps lightly on the rearview mirror.

"We all know that, don't we?" Donald Ripper in the passenger seat muttered. "She's the type of person who doesn't give up easily until she gets an answer. But until the little lady is done, we will all have to continue watching this kind of thing. ”

"Oh, Don. It's a sight you can't even see on a flight back then. And, how long do you think it's been now? ”

Mr. Noft struck the clock.

Very, very incredible. Although the Dome had been in the back seat for more than an hour, the hands on the clock had only moved five scales.

"I just hope you don't have a problem in your brain like it did back then."

"Hey, old man. Even back then, I didn't make it to the point where my brain went wrong, remember? ”

"Unfortunately, it's not us who have the problem now. I hope the little lady can ......"

The conversation between the two gentlemen continued, but it was no longer audible to anyone.

Even the sound of the wind is fading away.

Silence. Only a more grotesque, more beautiful, more eternal light than a fairy tale remains.

_

Rustle.

The sound of the pen tip flowing, like the sound of gently plucked strings, drowned out all the noise.

Little by little, the answer is emerging.

Well, how to say it? Although the calculation is not yet complete, the dome is roughly understood.

My father's argument back then, that the design of the universe was made in a box, at least in theory, was not obviously wrong. Rather, it is because it makes so much sense that even the means to achieve this end, Dome can imagine one or two according to the paper.

For example, a virtual electron-anti-electron pair that mimics the electric field effect becomes a real electron and an anti-electron at concentrated energy. If a small piece of space can be heated to an astonishing degree, then when it cools down, there will in principle be a tiny virtual universe like virtual electron-antielectron pairs. When this small imaginary universe becomes real, it will have the potential to expand from the other side of the singularity under the influence of anti-gravity, thus becoming the real universe as we understand it. Although we will not see this process on our side, at least for a considerable period of time, the wormhole will remain, giving us the opportunity to learn the true nature of the new universe that was born on the other side.

Of course, the specific design of this part does not exist in my father's thesis. My father only proved the feasibility of creating the universe, and the specific steps to create the universe were completely self-exerting of the dome.

It is said that the ancient Greek mathematician Archimedes calculated how much sand and gravel needed to fill the entire universe, which is already a great image. However, even Archimedes' imagination is too small compared to his father's proof.

How far it will be feasible is a topic that cannot be assessed at all. But at least, in the verification of the dome, no theory has been found that can prevent this.

At this point, writing and computing have become inertia. As the calculation came to an end, a doubt inevitably popped up in his heart.

As the teacher said, my father's thesis was a strange story. But excluding the element of bizarre theory, it is also as the teacher said, and does not contain any element of nonsense.

His father once said that because he had no talent for it, he gave up physics and got everything else. But judging from this paper, which seems to be closer to a game work, the so-called "lack of talent in this area" is undoubtedly an untenable excuse.

Only Dome who has completed a complete mathematical verification can know how correct his father's paper is. From theory to mathematical calculations, it is almost flawless. As long as the laws of physics that we now grasp are not too far wrong, the infinitely developed civilization assumed by my father will inevitably follow this path. Perhaps, that is the very distant future of humanity.

Gently put down the quill pen, and the universe that is literally calculated from the tip of the pen exists in this stack of papers.

What was it that changed my father?

When she finally wrote "Q.E.D", the doubt spread to the deepest part of her heart.

Turn your gaze out the window. Under the cover of night, the lights paved a new path, leading straight to the darkness created by the light control.

The night is inevitably dyed with layers of light.

========================================================================

Note 1: By the way, Feynman and Wheeler also like to read other people's papers in this way.

Note 2: I mentioned the relativistic shrinkage effect before, and many people should remember it. But I don't know if anyone has noticed here that when I mention the relativistic contraction effect, I mention the slowdown of time, but I don't mention another manifestation, which is the contraction of length in the direction of motion. That is, when we look at a ruler that is moving at high speed, we should feel that the ruler has become shorter. This is an important feature of the theory of relativity, but I have deliberately ignored it throughout this article. Why? In fact, this is because, although the relativistic shrinkage effect does cause the length of an object to shrink in the direction of motion, it is likely that we will not "see" this phenomenon when we observe it. It is very likely that the ruler in our "eyes" is still the original length. The reason for this is very interesting, so please think about why. Hint: The speed of light is limited.

But beware, what we see at high speeds is indeed distorted.
