Black technology: starting with space jump machine

Lu Yu's support plays a decisive role in this proposal.

With the development of human civilization to this day, the promotional role of the Silver Star is self-evident.

What's more, with Lu Yu as a window, humans have seen the vastness of the universe and so many civilizations.

If we relied on our own strength, how many twists and turns would we have to go through to get to this point?

Just looking at the database of cosmic sociology, there is a large number of social data on civilizations, including more than 33,000 planet-level civilizations and more than 300 star-level civilizations.

This is not something picked up casually.

I really want to build the current scale of the database. Without millions of years of civilization observation and communication, it would be impossible to obtain so many civilization observation samples.

But now, relying on Lu Yu's window, humans can easily obtain them, and even understand the civilizations in the universe better than some star-level civilizations that have been in the starry sky for hundreds of thousands of years.

This is also reflected in a discipline.

In terms of basic science and cutting-edge technology, the reliance on Lu Yu is even more serious.

Whether it is the observation of space technology samples or the research on various technologies of Zerg spacecraft, these major projects can only be realized by relying on the Silver Star.

From the perspective of cutting-edge scientific research, once Lu Yu is missing as a bridge, human scientific and technological research will almost instantly go back hundreds of years.

Therefore, it is not unreasonable for the system to judge that Blue Star humans are Lu Yu's vassals.

At this time, Lu Yu was the first to stand up and support the proposal. No one could ignore his decision just because he was still in deep space.

On the contrary, because he is in deep space, Blue Star humans have to pay more attention to any of his opinions.

So when Lu Yu came forward, the strategy seminar unanimously chose the suspension proposal.

But it does not mean that the deep space project will be stopped. The Great Space Wall project has reached a critical period. No one can stop the first stellar-level project bred by human technology.

"Do you think that if the humans of Blue Star were not threatened by the unknown fleet, would they be able to explore the solar system faster than they are now?"

The Q-version avatar of No. 7 popped up a dialog box: "If there was no pressure to survive, then human beings would probably still be immersed in the construction of the earth-moon system, and many technologies would be slowly released due to taking into account various factors."

"The Lagrange point space city will be delayed by stimulating the collective overreaction of the entire human race. The first spaceship will only reach Mars and then return and advance to the base."

The analysis of No. 7 is not a fiction. It combines the logical analysis of human thinking and the terrifying computing power to construct a prediction of human behavior. It can only be said that big data may know itself better than itself.

But after the meeting was suspended, Lu Yu stayed in the personal space of virtual reality. Instead of relaxing in various ways, he let No. 7 access the signal. He looked back at the single-celled organisms he had discovered in the acid sea.

In the virtual reality scene, Lu Yu seemed to be standing on a dark, turbid acid sea, and there was a clearer sea below him, where those tenacious single-celled life could survive.

It's just that now this seemingly clear area is beginning to be eroded little by little by the surrounding turbid sea. Due to the drastic changes in the environment, the pH value rapidly decreases, and these single-celled organisms die in large numbers in the acidic environment.

Only a small number of single-celled beings hid in the layers of corpses of their kind, barely surviving by relying on thickened cell walls to hibernate.

This scene reminded Lu Yu of his analysis of Blue Star's ancient times. The environment of Blue Star was not suitable for the survival of today's creatures.

Taking oxygen as an example, in today's nature, oxygen is not only widely distributed in the atmosphere, but also has the highest content of oxygen in the earth's crust, accounting for 48.6% of the mass of the earth's crust. It is used for the oxidation of hydrocarbons, wastewater treatment, and rocket propulsion. Agents, aviation, and aerospace work all require oxygen to carry out.

Nowadays, animals' respiration, life reactions, and all oxidation reactions require oxygen. Although a large amount of oxygen is consumed every day, the oxygen in the atmosphere will still remain at a relatively constant value because the photosynthesis of plants is constantly changing. Add oxygen to the atmosphere.

Therefore, many human beings' first impression of oxygen must be that "life cannot be separated from oxygen", because the breathing of life is to obtain oxygen in the air. If there is a lack of oxygen, life will die of lack of oxygen.

However, for some life forms, oxygen is "poison". These strange anaerobic organisms are an important reason why Blue Star can develop human civilization today!

Long before Lu Yu stepped into the starry sky, anthropologists had sufficient evidence to show that the oxygen content in the Blue Star's atmosphere was not high in ancient times.

And all these changes will begin with the birth of the first batch of life on Blue Star!

The earliest life on the Blue Star appeared about 4 billion years ago. The current Blue Star is about 4.6 billion years old. The oxygen content of the Blue Star's atmosphere began to gradually increase 2.6 billion years ago. This means that the early life on the Blue Star did not require oxygen!

The first life of the blue star was born in the depths of the ocean. They do not need oxygen or the heat of the sun, but rely on the "hot springs" deep in the ocean. The heat of these hot springs comes from the lava seeping out of the blue star. There are a lot of chemicals near these seafloor hot springs, and the first life on Blue Star was created in this environment.

The first life forms on the Blue Star were prokaryotes with relatively simple structures, and they were all "anaerobic organisms" that did not require oxygen. For these organisms, oxygen was really "poison."

Archaea may be the oldest life form. They can survive in various extreme natural environments. Whether it is lake water with high salt content or extremely hot, acidic and absolutely anaerobic environments, archaea can survive safely. Archaea can survive even in extreme cold.

Archaea like extreme environments, and the extreme anaerobic characteristics of some archaea actually hint to humans who later excavated this period of history. These oldest life forms went through a very difficult period before evolving these characteristics, which is just right. The answer is the same as what anthropologists have gotten from the strata: the early blue stars had a harsh environment and were extremely hypoxic.

Since there was no oxygen in the atmosphere of early blue stars, life at that time was anaerobic. For these creatures, oxygen was really "poison", but for the vast majority of life on blue stars now, oxygen is It is an indispensable necessity. To say that oxygen is a "chronic poison" is just sensationalism.

If there was no oxygen, the life on the Blue Star would still be archaea with a simple structure. How could it be possible to build complex and diverse life systems, and then wisdom would be born in order to adapt to the environment. Without wisdom, the foundation of scientific and technological civilization would no longer exist. .

So, what happened that caused oxygen to start to appear in the atmosphere of the blue star?

The simplest and most direct reason is that there is a kind of creature that has evolved a unique skill "photosynthesis". Cyanobacteria are primitive single-celled life, but this kind of creature can perform photosynthesis. Cyanobacteria do not have chlorophyll, but They can still perform oxygenic photosynthesis.

The emergence of cyanobacteria allowed blue stars to develop from anaerobic and low-oxygen to modern blue stars with sufficient oxygen content. The emergence of oxygen is one of the basic factors that complicates life. This is a good proof that eukaryotic life is generally larger than prokaryotic life.

In addition to cyanobacteria, Blue Star also experienced some environmental changes at that time. There were a large number of "methane bacteria" in the ocean at that time. These bacteria would release methane during their metabolism, and the appearance of methane would inhibit and reduce the increase in oxygen. When atmospheric oxidation events occur, these methane bacteria die on a large scale for unknown reasons. Therefore, it is not only the cyanobacteria that are releasing oxygen, but greenhouse gases are also relatively reduced, providing a more suitable basis for the increase in oxygen.

Without the emergence of life like cyanobacteria and the coincidence of environmental changes, the earth may become a second Venus. The severe greenhouse effect will make the planet's environment extremely harsh, thus rejecting civilization before the initial filter. .

And could the single-cell life in front of us, born in the acid sea, be the life form that could change the fate of the entire planet?

Just like the cyanobacteria on Blue Star, it took hundreds of millions of years and countless generations of life to abruptly change the entire planet.

Perhaps on this nameless planet, these single-celled life forms had worked hard for hundreds of millions of years before Lu Yu arrived to open up the sea area in front of them, but it was obvious that they were still far, far away from success.

It may take hundreds of millions of years, or perhaps even until the star turns into a red giant, it still won't turn this planet into a planet suitable for nurturing intelligent life.

Lu Yu looked at the layers of dead single-cell life. When the turbid acid sea eroded them, a surprising scene appeared. The turbid acid sea became clear again.

"It turns out that the acid and alkali have neutralized it?"

"Can the corpses of those single-cell organisms secrete alkaline substances when exposed to strong acid?"

Data analysis in virtual reality allowed Lu Yu to understand what happened. But the more this happened, the more he couldn't help but think deeply.

If we look at the vast universe, the environment of the universe is not suitable for civilization, but isn't civilization just like cyanobacteria and these single-celled life forms that have difficulty surviving in the universe?

So... will one day, through the efforts of generations of civilizations, be able to transform the universe into an environment suitable for civilization to survive?

Like cyanobacteria, like these single-celled lives?

This answer cannot be obtained by Lu Yu now, but if he can survive those long, long years, he may have a chance to witness that moment, right?

"Civility, civilization."

Lu Yu recited it several times in a low voice, and finally exited the virtual reality.

Opening his eyes in reality, he was lying on the soft grass, his head resting on Seven's lap.

Today's virtual reality helmets have been replaced for several generations. As long as film-like electrodes are attached to several key locations on the head, you can connect to virtual reality.

Before Lu Yu left Blue Star, he couldn't believe that this kind of technology would one day be implemented.

Now, virtual reality technology has penetrated into every corner of human civilization, and new ideas triggered by it are sprouting.

If applied to other civilizations, such new ideas will affect civilization for hundreds of years to come.

It's just a pity that such new ideas will soon fall behind due to a new round of productivity explosion on Blue Star.

Maybe the human civilization in the big universe, that is, Blue Star, enjoys this magical treatment?

As long as you have enough time, you will be able to step into a star-level civilization without any obstacles, and you can even ignore the big filter that third-level civilization has to work hard to get through.

"Is there any movement in the triangular spacecraft these days?"

Lu Yu still enjoyed the soft and smooth special pillow, and No. 7's skin was no different from that of a real person.

This kind of bionic human technology is already quite mature on Blue Star. Lu Yu once used virtual reality to see the street scenes of several emerging cities. He once thought he was on the set of a certain game.

And with No. 7 here, humans don't have to worry about the omnic crisis that Level 3 civilizations are deeply afraid of.

"Still the same, the ring family seems not to use the gravitational lensing method, but to use a more covert and efficient space-related observation method."

"Our understanding of space technology is really still blank, so we can only keep it as it is."

The original situation is just not talking and pretending to be an expert.

The pleasant voice rang in his ears, and Lu Yu just shook his head slightly helplessly.

He had already prepared for the issue of the concept of time.

Spending a month here motionless is probably just a short moment in the life of the members of the Ring Clan civilization, which is not as good as one second in the human experience.

But for humans, one month is equivalent to one thousandth of a life.

In the past, before Lu Yu left Blue Star, a person's life span was only a thousand months.

One thousandth, compared to one second in other civilizations.

Time shows completely different attitudes to creatures of different civilizations.

"Why don't you go back to the folding space?"

"At least you don't have to watch single-cell organisms reproduce there all the time. You can also earn some points by giving lessons to those super beings!"

"I don't know how long it will take for this triangular spacecraft to finish its observation. If it is like that lucky star-level civilization, it has been here for hundreds of years...then this mission is basically aborted."

"Why don't you settle [Exploring the Starry Sky] first, collect enough points, repair the Silver Star, and then find a way to return to the solar system before considering the mission of the Ring Clan civilization?"

Lu Yu was thinking about whether to throw the triangular spaceship away for a while, when he felt No. 7's little hand being gentle on his solar system.

"What's wrong?"

Lu Yu opened his eyes again and asked. He knew that nothing was wrong. No. 7 would not disturb him when he closed his eyes to rest. She would just wait silently for him to wake up.

This is the tacit understanding the two have developed over the years.

"The triangular ship has sent a message."

Seeing Lu Yu open his eyes, she continued: "The results of the observation of the target star system are in!"
