When the binary number of n is released to 2.2 trillion digits after the decimal point, the huge amount of data is read by the decoder, finally showing a hint of nil.

As the Ark speculated, the civilization that sent these mathematical formulas to Earth has been observing Earth's civilization for quite some time, and there is already some understanding of the means of information exchange on Earth.

And what's striking is that all this huge information is compressed into an irrational number of less than a byte.

Surprised at how they sent this irrational number to Earth, the Ark actually wanted to know how they managed to release such a huge amount of information with a number…

Jinling Institute of Advanced Studies underground laboratory.

A canoe lying flat on a bed, wearing the latest holographic helmet.

Although worried about the security of the data, Em followed the orders of the Ark and initiated the procedure.

Soon, a white space descended.

A world that is no different from the space of the system, presented in front of the ark.

Unlike the system space, however, it is not the familiar holographic panel that sits in the system space, but rather the man who… reproduces himself as a blueprint.

However, although it is a "reproduction" based on itself, some adjustments have been made, both by the five officials and in some detail, if you look closely.

It is said that creatures like humans are more likely to favor individuals who resemble themselves, while non-twin individuals who resemble themselves are instinctively excluded.

It is not known whether this is the reason why he chose to meet himself in this form, nor is the Ark a psychologist, much less to dissect the heart of this apostle suspected of coming from a higher civilization.

And the only thing he could tell was that at least this contact was not incidental to hostility.

“How did you do that? ”

Looking at the man standing in front of him, Ark quickly said, "Pushing huge amounts of data into an irrational number… No, before you tell me, how did you do anything to create an irrational number? ”

This statement appears to be somewhat intransigent, but the Ark believes he must be able to understand his confusion.

Expressing a particular irrational number in the concept of abstract numbers is not just the extent of the mathematical dilemma, but has risen to the point where one is doubtful whether it can be done.

Faced with the question of the ark, the man showed a somewhat sad expression and spoke in a gentle tone.

“… in ancient memories we were as ignorant as you were, when the real numbers we came into contact with were basically rational, but over the centuries we gradually discovered that almost all the real numbers were unreasonable. ”

Ark: “… we know that too. ”

Looking at the expression on the face of the ark, the man suddenly showed a glimmer of suddenness on his face and continued.

“Don't get me wrong, ignorance is not a derogatory term in our civilization, even… is an enviable quality. Because only ignorant people are curious, and curiosity is the vitality of civilization. Once you lose your curiosity, even if your civilization is all-knowing, it will disappear over time… Of course, you are too young to imagine the feeling of being inundated by endless emptiness at a stage where a problem is solved and countless new problems arise. ”

Ark: “While the omnipotence in your mouth is quite enviable, I... can probably understand what you're trying to say. ”

Poets often compare themselves to birds or birds. Knowing more doesn't necessarily mean being happier, in fact the vast majority of the troubles come from knowing.

This is true for individuals.

The same is true of civilization.

“Well, I like you,” it seems, "reads the idea in the heart of the ark, with a praiseworthy look on his face," I've seen two commendable qualities on you. ”

The Ark thought about it for a while.

“… self-aware? ”

“It's three now, you're smart. ”

The man smiled and continued, "But I'm afraid I can't answer two questions about you. This is about the truth of the universe… what you call knowledge, the information about this part, is not included in this procedure, and we would prefer it if you could look for answers yourself. ”

“Of course, if I had the chance to meet you, I'd be willing to talk to you in person about those interesting things, but that may not be a good thing for you. ”

Ark: “…”

It feels like being watched and praised like a gorilla in a zoo, and the ark doesn't know whether to be happy or angry at this time.

Of course, perhaps more helpless.

Thinking of this “person” in front of us may be stronger than the sum of the armed forces on Earth, the Ark feels it would be better to perform a little more steadily at this time, even for the sake of others.

At least, so far, he has approached himself in good faith.

Ark: “Can I ask you a question? ”

“Ask. ”

“Your name. ”

The man thought for a while and said.

“It's a bit complicated, even more complicated than the first one… We've long since abandoned the need to rely on media communication methods, including limbs, audio, electromagnetic waves, and even gravitational waves, and we've long since distinguished each other by the availability of names… Of course, if it's for convenience, you can call me an observer, which is my favorite word in your dictionary. ”

What a strange aesthetic.

However, the name is only a code name, and the Ark has not been more involved in this irrelevant issue and continues to ask.

“What is void? What is a natural disaster? And that strange drip ——” Thinking about what this observer said earlier, the ark was silent for half a second, and he said, “The strange drip thing is off the table, you should tell me the first two questions. ”

The man nodded with a smile.

The look on your “really smart” face came back to his face.

As if he were reading a poem, he spoke with a repressive voice, not slowly.

“A void is a void, and everything about it is a mystery to us, even for walking into it. It is independent of the universe, and if, according to your interpretation, the universe consists of n vibrating strings, then it is the n +1 string outside the n string, an additional dimension outside the n dimension. It's a wall on the wall, it's a reflective lake in the lake, and it contains all the energy and matter in this universe, yet it has nothing. ”

This time, the Ark finally got the feeling that someone else was listening to his debriefing.

Combined with M theory, he barely understood what kind of concept the void described in the observer's mouth was, but he still didn't understand how civilization could survive in such a space.

And even if civilization exists, how does it communicate with this side of the universe?

“As for natural disasters…” the observer's eyes were slightly saddened and silenced for a while before sighing an opening, "these are too early for you. ”

Ark: “I don't understand... if, according to you, the void is an extra dimension outside of the N-dimension, then everything about it should be independent of the N-dimension. If so, how did you get in touch with me? And how it affects those who dream of you. ”

There was a glimmer of praise in his eyes, the man said with a smile.

“I'm getting more and more fond of you, most people panic when they see me, or stubbornly think I'm talking nonsense, only you try to communicate with rational thinking and me... although I feel you may not believe me, at least you're willing to assume that this is all a real possibility. ”

The ship did not speak, but waited for him to continue.

Pause, the man claiming to be an observer, continued.

“When the old universe went out, we made some preparations, and you can understand that when the flood came, we built a dam. Because of these preparations, we can limit our interference with civilizations that are connected to us… Although the bonds between us are weak, too much energy is too mysterious for you to interfere with that connection, and very few individuals, even if they are aware of our existence, have difficulty convincing their fellow human beings to persuade themselves. ”

“So every once in a while, we try to release some of the signals we need to accelerate your civilization to a certain extent, which you can call enlightenment. And of course, this seedling-fuelled way is not without harm, like a supernova, inflation is dying, so we're doing it as thin as ice. Let you grow as much as possible without overhanging the potential of the future. ”

Ark: “… Looks like you've poured a lot of resources on me? ”

The observer smiled kindly.

“Yeah, so if you don't see these things, we might lose a lot. But this probability is small, and even if our calculations are missed, subsequent plans can cover them. ”

The Ark is unsure whether what he calls “these things" refers to Professor Grotendik's notes or to the “system” he owns. But it is, and it is, and it is true that I was guided by so many things that I ended up here.

He just doesn't understand something else.

That's why they did it.

Or even if a group of ants knew the flood was coming, what could they expect?

It's not that he's paranoid, it's just that in mathematics, physics and informatics, he really doesn't have the courage to compare Earth's civilization to the void civilization behind the observer in front of him.

If they can't resist making strange drops, what good is it to tell a global civilization that even building a hydrogen bomb would take a lot of effort?

“… wouldn't it be better to tell us about the crisis if you were really going to solve it? ”

Like watching his own child, the observer suddenly laughed and spoke softly.

“Is that really true? ”

“All our decisions have been the result of lessons learned from hundreds of millions of failures, as well as trillions of calculations. It may not be understandable to think from your point of view, but it's actually the best option. ”

“We must ensure that every gravel in the hourglass falls precisely into the bottle and that everything moves in the right direction as the final moment approaches… Of course, that being said, we have not failed. ”

“Remember the story of the Coke Empire? ”

The ark did not speak, just nodded.

“I'm glad you remember, so that we can continue our conversation," the observer nodded with a smile, pausing for a moment, continuing, "Two hundred years after the 'Oracle Event', this historic civilization, at an incredible rate, became the dust of the universe and disappeared into the world. ”

Indeed...

See if your guess is right.

Coffee civilization has become history, perhaps even from the “Old Universe” of this observer. If you put it that way, that memory might have been before the Big Bang.

Because it was so surprising, it took two seconds for the ark to digest the shock in its heart and take a deep breath to say.

“… because of a ‘natural disaster’? ”

“Natural disaster? Natural disasters are not so weak. On the contrary, it's man-made. ”

It seemed to read out the surprise on the face of the ark, the man continued.

“What happened to the Coke Empire was unexpected, and we had no idea that it was not the natural disaster that swept through the universe that destroyed them, but their own. ”

“Fortunately, however, this memory has been preserved and has given us many revelations. ”

Ark: “Memories? What memories? ”

“You have a bit of a problem, but so far everything seems to be within your expectations except the first one that I expected. ”

“As for the memory of your curiosity, naturally it is the follow-up to the previous memory - that is, the second half of ‘b', about fifty years later. ”

The man smiled and extended his right hand forward, lifting a cubic body of light blue particles.

“It should be about time. ”

“If you had received that quantum computer, the decoding would have been here by now. ”

The ship was about to ask what “here” meant, and the white light around it cracked backwards like debris. That pale blue cuboid twisted the surrounding space like a black hole and released countless pieces of clear debris, flying towards the butterfly and into the surrounding corners.

Though he did not know what had happened, the heart of the ark told him.

This should be the world depicted in Void Memory b2!

The story has begun…
