Start a Subspace

Dr. Xia took a deep breath, and said: In addition, the speed at which cosmic string vibrations propagate is only the speed of light, so if you want to travel at the fastest speed over a long distance, you must propagate in multiple spaces at the same time.

These particularly bright spots on the image should be the transmission points of the gravitational broadcast. This advanced civilization may try to inform the rest of the civilizations to jointly resist the disaster.

Are we late? asked one scientist.

Well, roughly, the closest gravitational broadcast point to us is in the Andromeda galaxy, which is 2.5 million light-years away from us. It should be too late now, and the Andromeda galaxy collapsed thousands of years earlier than the Milky Way... and we can't catch up so far the journey.

If there is a refuge made by an advanced civilization, won't it collapse? Lin Qiuyue suddenly thought of something and asked, We have traveled 60,000 light-years through high-dimensional transitions. Even millions of light-years The distance is not impossible.

Is there a marked, absolutely safe location for this civilization?

Dr. Xia seemed to be stopped by the question: I haven't found an absolutely safe place. As for whether there is a shelter there, I don't know.

But even if the high-dimensional transition is indeed possible to hurry, our technical level may not be able to reach the minimum level of cooperation. Maybe we will be treated like paramecium.

When the other party sent the gravitational broadcast, the universe had not yet collapsed, and high-dimensional transitions were not as simple and common as they are now. Cosmic civilizations that want to cooperate will most likely be driven by superluminal curvature engines.

But our curvature engine...uh... He spread his hands and smiled, meaning that the human curvature engine is simply a counterfeit.

Zhang Ran smiled. In the eyes of the other party, human civilization should be a low-level civilization hiding in the small universe: If it is possible, go there and take a look. It seems that there will be no loss. At least we have received the broadcast signal , isn't it?

He thought of something else: Dr. Xia, this broadcast has been broadcast for 500 million years, and the universe has persisted for so long. Is it the result of the joint efforts of these civilizations? In theory, the universe will be torn apart 500 million years ago?

Dr. Xia shook his head: It's possible, but I'm not sure.

The starting point of the big rip is the Great Eridanus Void, 15 billion light-years away, and we don't know what happened there.

The speed of the big rip must exceed the speed of light. If it is less than 30 times the speed of light, it means that the efforts of these civilizations are useless, or they did not work hard at all, or their efforts failed; These civilizations did gain some time, but ultimately lost...

All in all, they must have failed...

Dr. Xia's introduction quickly attracted more scientists to participate in the discussion.

People even discovered some tech presentations hidden in the pictures!

High-level civilizations drew many strange low-level creatures on the radio, but they actually had ulterior motives.

According to the analysis and speculation of experts, the number of planetary systems that can give birth to life is about one-fifteenth.

That is, among a hundred stars, 6-7 stars can give birth to life.

This probability is higher than human imagination...

It can even be said to be much higher!

Among the planets where life is born, there is a probability of about one-fifth to one-sixth that a serious intelligent life with a neural network as the core can be born.

Next, the image depicts the state of the spaceship sailing into the starry sky, that is, civilizations without interstellar colonization are all non-influential.

Professor Huo said on stage: Let me analyze the data given by high-level civilizations. According to this paragraph, the probability of the birth of intelligent life is one in ninety. There are hundreds of billions of planetary systems in the Milky Way, and the number of intelligent races is Billion.

The civilization with enough wisdom to produce the first industrial revolution has a pass rate of 1% when it is around 10 million. It may be due to the geological phenomena of the planet itself, the degree of abundance of resources, social factors, natural disasters and man-made disasters, and the degree of intelligence. One screening.

We are considered one in ten million races to pass. Are human beings considered intelligent? If the number of intelligent races is one billion, we are considered to be in the top one percent.

Zhang Ran sat in his seat, a little curious about this statement, Why do I always feel that human beings are so stretched. Is it true that there is wisdom and civilization, and even the industrial revolution can't be completed?

Professor Huo shook his head: It's not that I'm racist. The Industrial Revolution has higher requirements for intelligence, but higher requirements for culture and society.

In certain areas on the earth, their culture is doomed. Without outside help, the industrial revolution will not be completed in a lifetime. Some people help them, and they think it is a gift from the gods. If you have money, you can lie down. If you don't have money I will work part-time for a day or two, and continue to lie down after getting paid...

Extend the people in this area to the entire race, and you will understand. If a certain alien race is indeed like this, I don't think it is surprising that the industrial revolution cannot be developed.

Zhang Ran was stunned for a moment, and sighed: That's right, people in some places don't even bother to farm, let alone develop any industry...

After explaining these questions, Professor Huo continued: ...the number of civilizations that can invent nuclear fusion, have the courage to leave the planet, and colonize their own satellites is at the level of 100,000. This is a very big threshold, and the pass rate is 100% For a while, the reason may be that the requirements for materials in fusion engineering are too difficult, and the amount of money that needs to be invested is too large. For the whole society, this long-term investment is a huge challenge.

Comparatively speaking, solar energy is a relatively cheap renewable energy source, and it is economically profitable.

Most civilizations lost the opportunity to develop nuclear fusion after the advent of cheap solar technology.

Once they're no longer starved of energy, they don't have the incentive to do the fusion project.

On the contrary, civilizations that have entered the metaverse era, at the level of millions to tens of millions, are not considered a real screening. It can be seen that the semiconductor revolution is not considered a difficult technology...

An expert on semiconductors pressed the button to speak: In fact, this kind of necessity, at least at the application level, semiconductors are irreplaceable in our world. The pursuit of computing power is the common goal of most intelligent civilizations. The goal is also to meet the needs of the market, so the semiconductor industry will definitely become more and more developed. It has to be admitted that economics rules our universe.”

Zhang Ran smiled and nodded: That's right, economics is the crown of sociology, aren't all of us worrying about funding for scientific research?

Huo Dong continued, The era of nuclear fusion and the era of metaverse can be regarded as two parallel eras, which can be entered at the same time. The fourth industrial revolution and the fifth industrial revolution have no obvious relationship between superiors and subordinates, but only social forms. The difference is huge.”

Nuclear fusion civilization is almost 100% able to enter the metaverse era, and vice versa is not true. For example, Sibadi civilization, they do not have fusion technology, but they also developed 3D chips, which raised the performance of semiconductors to the limit.

Of course, the development potential of civilizations without nuclear fusion technology is just like this. The economic scale limits all aspects of them.

Another scientist raised his hand and asked, What about the next era? What is the next industrial revolution?

Professor Huo said: In the next era, the expression on the picture is a little blurry...

It seems that there is no next clear era. If there is one, it is also the era of artificial intelligence. The probability of passing is very low and it is not clearly articulated.

This is a very high threshold. Passing this threshold will lead to the singularity.

The picture is very abstract, with intelligent creatures and machines stacked together...it should be the era of advanced artificial intelligence, right?

There are also various incredible things such as accelerators around the solar system, planetary fortresses, etc., which also appeared in this era...

In addition, this advanced civilization is extremely respectful of neural network technology, and has drawn a variety of neural network structures. Of course, there may be some problems with our interpretation. That's probably it.

Next, after Professor Huo finished his explanation, another scientist came to the stage to analyze some conjectures about the small universe.

Of course, these conjectures seem a bit esoteric, and the various technical terms are completely incomprehensible, so they are not Zhang Ran's main concern.

After all, human beings already have the curvature technology of the three-legged cat. No matter how powerful the movement of the small universe is, it is still incomparable with the curvature technology.

...

The meeting gradually dissipated, and the information from Cosmic Strings shocked people a lot, but also brought a lot of gains.

Many experts are still enthusiastically discussing the basic principles of the microcosm, cosmic strings and microcosms, topological linkage of microcosms, as well as neural networks, artificial intelligence, advanced civilizations, etc...

Of course, any experiments based on small universes need to be strictly reviewed.

If it really explodes, it will be an explosion comparable to a supernova...

In fact, Zhang Ran is quite satisfied with the current situation: Speaking of which, we are really much stronger. We know more information, and science and technology have also improved. In the past, our ability to connect to and receive information from advanced civilizations No.

Military level...it's okay.

Just like the Dongfang Panshi traveled to the previous era of the earth, it only took a few minutes to defeat the earth coalition forces! Especially the ultra-large laser emitted by high-dimensional silicon crystals, which is a light-speed weapon that can instantly melt an aircraft carrier.

There is no need to fight, the Earth Alliance might surrender...

But there is no peace in the universe!

Compared with truly powerful civilizations, compared with civilizations that often use the mass of the sun as their energy unit, human beings are still too weak...

Oh, by the way... isn't artificial intelligence and neural networks your research direction? Zhang Ran turned his head and looked at Lin Qiuyue, Do you have a goal for the next step of development? For example, strong artificial intelligence or something.
