Gamma ray bursts, the largest and most desperate disaster in the universe.

It is theorized that the Earth's first mass extinction occurred more than 600 million years ago in the Ordovician period because the Earth was hit by a gamma shot 6,000 light-years away.

At that time, two suns appeared in the sky, 70% of the atmosphere was destroyed, the base of the marine life chain was destroyed, and 85% of the species disappeared from the earth.

Fortunately, the distance of 6,000 light years is long enough, and it is not swept head-on, and the first mass extinction on the earth was not very complete, but made vertebrates the new overlords of the earth.

However, in the moment before the explosion of the earth, humanity still did not shake off the deep fear of such a catastrophe.

People were shocked to discover that 8,000 light-years away, there was a star called R104, which was about to explode.

At that time, there may be gamma rays passing over the Earth...... I don't know what the impact will be......

At a distance of 8,000 light years, earthlings are still afraid, let alone the Tucker civilization, which is only more than 100 light years away and is directly aligned by the rotation axis of stars?

If you don't run away, you'll die!

I saw that the metal plate continued to write:

"After discovering this sensational fact, we launched these probes as fast as we could, hoping that they would escape. They carry a part of our hopes. ”

"We also intend to exhaust the power of the entire civilization to develop controlled nuclear fusion technology. We will use all the fossil energy to build a spaceship that can accommodate a large population. At the same time, the Super Shelter is being built urgently...... These are two different scenarios. ”

"Hopefully we have enough time, hopefully the universe ...... Hopefully, that superstar will give us a few hundred more years. Time, time, we don't have enough time......"

"Tucker civilization, recorded in, 011110011011 AD, detector number 00011010100."

This is the end of this letter.

Everyone was slightly melancholy, because the phrase "controlled nuclear fusion technology" was mentioned. People clearly know how difficult it is, at least ...... Humanity has not yet made it happen.

"The future of this civilization does not seem to be very bright...... And how much work is required for a spaceship that can accommodate everyone...... Super Vault is still a bit viable......" One scientist opened his mouth, shook his head again, and didn't say any more.

Obviously, he is not optimistic about the escape project of the Tucker civilization.

“…… Even if a super shelter is built, if the planet's atmosphere is blown away and the ecological chain is greatly destroyed, the life inside will not survive for a few years. More than a hundred light years, still too close and too close. Yu Yifeng shook his head.

Time flies, time flies.

150 million years, this unimaginably long time has passed...... All history is condensed into just a few bits: more than 200 pages of metal sheets, plus a metal plate.

In the endless passage of time, the greatest individual became a name.

The most powerful country is only a short record.

How many things have happened in history?

Someone is crying, someone is laughing, someone is sick, someone is parting from life and death...... All the major events related to oneself, all kinds of survival struggles, all kinds of laughter and scolding, in the face of endless time, seem so insignificant.

There is not even a trace of existence, what is the crying and laughing that used to be.

The final outcome of the Tucker civilization is unknown to mankind.

Even from the current point of view, the image of the Milky Way they drew at that time is incorrect. 150 million years later, astronomers have been unable to find the planet on which they lived.

"Can't find it, because the Milky Way is also in motion...... It's hard to guess......" Professor Thomson of the Observatory waved his hand regretfully.

There was silence in the conference room.

Seeing the lone detector again, and the last remaining information, everyone present suddenly felt an incomparable sense of panic in their hearts.

If humanity encounters a truly insurmountable catastrophe, will it do the same?

Will you record all your wisdom and pass it on to the underworld...... The Next Civilization?

Could it be that Noah on the moon ...... Is the same true?

People are confused and scared.

When its future existence could not be determined, the Tucker civilization chose genetic inheritance or spiritual inheritance......

It's hard to comment on this kind of move, and perhaps it's the last resort, but it creates a panic that is hard to contain.

They don't even know why they're panicking.

Then, the metal disc began to play something new.

The following content is still the more important theorems of physics, mathematics, etc., of course...... There is no beyond the scope of human knowledge.

Something seems novel, but it's just the equivalent of an inference, and some experts are discussing it.

The new human civilization is much more advanced than them, and basically all of this knowledge is there.

The text on the screen, starting with calculus, moving on to advanced algebra, topology, functional analysis, real functions, ...... Many of the lessons are condensed into a few sentences.

The Tucker civilization lists what they consider to be the most important theorems, and even the proof process is omitted because of the space.

A low-level civilization needs a huge economic cost to launch any space probe, even a kilogram of material, so this civilization chooses to condense and re-endense information.

Some of the mathematical definitions are not quite the same as those of human beings, but the general idea is similar, that is, similar to Hilbert's axiomatism.

At the end, the other party also focused on the mathematical paradoxes caused by certain infinite problems, as well as the huge mathematical crisis brought about by set theory. The moment they ascended the probe into the sky, they did not resolve these mathematical contradictions, and I deeply regret it.

These are the same questions that mankind has puzzled about, the so-called third mathematical crisis. Today, the third mathematical crisis cannot be said to have been fundamentally eliminated, because many important issues in the foundation of mathematics and mathematical logic have not been fundamentally solved.

It is even known that it is impossible to completely resolve paradoxes and perplexities with the current method.

Because the great Gödel's incompleteness theorem irrefutably reveals the limitations of the formalist system, it mathematically proves the impossibility of trying to solve the paradox problem once and for all by the technical method of formalism......

In other words, the whole bottom-up scientific approach is not necessarily correct......

Perhaps, human beings will never be able to solve all the problems in this way, that is, they will not be able to fully understand the entire universe.

The last page of information was turned, and this inheritance of wisdom from ancient times finally came to an end.

The screen is blank, and the back is full of garbled characters, I don't know if it's because of the loss of information, or if it's the metal disk itself.

"Nope." The scientists here were stunned.

"There's no technology, it's all theoretical knowledge."

Even if they didn't get any epoch-making technology, everyone still felt that it came from the thick history of a low-level civilization.

It is a mission, a mission to convey wisdom even if it is destroyed immediately.

"When disaster strikes, what will humanity choose?"

At this time, a group leader in charge of testing the micro-ecosystem sent a message: "...... There is no living life in the microsphere, only traces of some life that once lived. No genetic material was detected, no complex organic matter...... Most of it has been hydrolyzed. ”

"We can't restore it, we don't even have protein."

This result is almost consistent with what people speculated.

Lack of energy, no life can last so long, and everything that can be broken down has been completely decomposed.

"The genetic inheritance of the Tucker civilization has failed...... But the spiritual inheritance remains in this world forever, and we have learned an extremely important lesson. ”

"Don't be too pessimistic, judging by this number, they have launched more than one detector...... Maybe the genetic inheritance on another planet has been successful? It is even possible that they have become an interstellar civilization! ”

The scientists here are not sentimental people, but they are trying to think on the bright side. The last fact, who knows?

But no matter what, the tragedy is still probable......

For the universe, what does the joy and sorrow of an individual and a civilization have to do with it?

But at this time, suddenly, a message popped up on the screen that surprised everyone.

At the end of the metal plate, there is still something! And the information!
