This kind of high-risk and unethical experimentation would be unthinkable in the 21st century, but it seems to be nothing now, and the necessary control measures should be in place.

The study of self-awareness and quantum randomness is an important part of strong artificial intelligence. If you want to continue to improve the strength of civilization, you must study these things, and people can't stop eating because of choking.

The Unreal Lab has always been the top security lab, and Zhang Yuan is still one of the four giants, so he feels that as long as he controls this aspect well, there will be no problems.

The two spent a whole day in the large ruins, and saw many stories from the past, including the unfinished "Vault 2".

The so-called No. 2 Vault was built for the Kunlun Mountain branch by the humans of this branch in order to reduce moral guilt.

As a result, the construction period was repeatedly delayed, and in the end, only two-thirds of the work was completed.

The rest of the piece, just left here quietly, can no longer be completed.

Lin Xuanxuan saw all kinds of idle machinery, piled up together in a mess. This is not a cultural heritage area, because the site is very large, there are often some middle school students in this place "panning for gold", if they can dismantle something, they can take it with them according to their preference.

Some cattle people even use these scrapped machinery to assemble a serious car!

There are also some robot games, which are also often held in this place.

She asked, "You say, if we had chosen the 3,000-year-old plan, would we be able to implement it now?" ”

"I don't know...... Or maybe it's like them? I just gave up after doing it. ”

Zhang Yuan shook his head, feeling a little melancholy.

This time, he really didn't know that human beings can be great sometimes, but most of the time they are very small.

As a qualified decision-maker, we must not pin all our hopes on the great side of human nature, but try to guard against the small and selfish side of human nature as much as possible.

……

After visiting the last part, the two walked out of the underground city and into a rail train.

At present, the main base of mankind is in the equatorial orbit opposite the planet, the nearest resource mineral point and the space elevator, in an area 800 kilometers away. The train moved slowly, and after such a long distance, it was still possible to see the space elevator towering in the sky.

At an altitude of 20,000 kilometers, a nuclear fusion electric lamp is hung, flashing with bright blue-white light, illuminating this piece of land.

In each of the Star Harbors, there are a total of six large motherships that are being built!

More than 100 million people can perfectly support more industrial projects, and the construction of projects for more than 1,000 years has also accumulated a huge amount of engineering experience for mankind. Five of these motherships are the size of the once Brilliant Galaxy, each capable of carrying the living life of 20 million people.

The giant spaceship in the middle, whose name is "Departure", is capable of carrying the lives of 50 million people. It is the largest spaceship that man can build, a veritable aerial giant.

If you use military terms, that is, the "Titan" level.

Zhang Yuan chose his position, looked at the nuclear fusion satellite lamp in the sky, and said: "Some scientists feel that we should develop our own planetary fortress. You have a great appetite right now, you have already developed a planetary fortress, and now you want to develop a second one. ”

"No matter how huge the spaceship is, it still can't be compared to the planetary fortress...... Whether it's the habitable population, the level of comfort, or the level of performance. ”

However, after discussion, this idea was abandoned for the time being. Because this battle star has to have curvature navigation technology, if you want to wrap the entire planet with curvature bubbles, we need to accumulate experience far from enough! ”

The engineering difficulty of curvature navigation is directly proportional to the volume of the curvature bubble, so the current spacecraft are basically circular. If it is a long ship, it will be more difficult to complete the curvature navigation.

After all, human beings have only just stepped into the fourth-level civilization, and there are still many things to explore, and it is a bit overwhelming to directly challenge the more difficult battle stars.

Lin Xuanxuan said: "It will take one or two thousand years to develop a battle star." Maybe in a thousand or two years, we'll already have this kind of technology? ”

Zhang Yuan spread his hands, "What if not, wouldn't you have to leave the planet here?" Don't forget, this hellish place doesn't even have a cosmic string, is it really a planetary engine that slowly moves out......"

"Of course, after accumulating enough technology, we will still choose to develop our own battle star. The battle star of the fourth-level civilization is called the battle star, and the third-level civilization is at most an iron lump that can move. ”

These large motherships look like flying saucers, with a spherical structure in the middle and a large centrifugal wheel around the outside, which looks a bit like Saturn's rings. At present, the main work is to build the main structure of the ship, and the most important curvature engine has not been installed.

Zhang Yuan looked up, "...... Because the speed of the curvature engine is too fast, it is still in a breakthrough period. This year, we can only reach 0.5 times the speed of light, and maybe in 2 years, we will be able to reach 0.6 times the speed of light! ”

"Don't be in a hurry to install the curvature engine and build the main structure, and when the curvature technology is perfected, human beings will soon be able to go back to the distance."

"Where are we going next?" Lin Xuanxuan said.

"It's not settled yet...... I'm sure you'll be looking for the nearest interstellar market. We are already a fourth-level civilization, and we should communicate with more fourth-level civilizations. ”

In just chatting, the two of them have taken the elevator and come to the Star Port, which is always so busy, and the throughput of all kinds of materials never stops.

These two days are legal holidays, and there are many tourists at the Star Port, and the crowd is bustling here laughing and talking.

Transport spaceships capable of reaching about 0.3 times the speed of light carry a large number of tourists into it and drop them on various tourist planets.

The speed of light of 0.3 times is actually very fast, and at 1 astronomical unit, which is equivalent to the distance between the Earth and the Sun, it takes only 174 minutes to orbit the star, less than 3 hours.

In the original Earth, it took one year to orbit the sun!

Each era has its own characteristics of the times, and the starry sky port is the place that can best highlight the richness of civilization.

Human spaceships can reach the corners of planetary systems, including the most distant planets, in a single day.

In the past, it took at least six months for the civilization of the earth to go from the moon base to the Jupiter base!

This is where the fourth-level civilization is far stronger than the second-level civilization, or even the third-level civilization.

Curvature technology brings endless possibilities. A sub-light speed curvature spaceship cannot be locked by radar, missiles and electromagnetic cannons are not as fast as others, lasers may be able to hit, but the hit rate will be reduced to an outrageous level, and one in ten thousand will not necessarily have ......

This is curvature technology, which people have been pursuing for thousands of years......

Zhang Yuan and Lin Xuanxuan were not interested in traveling in a spaceship. They came to the port, on the one hand, to be nostalgic for the past, and on the other hand, to have their own work tasks.

Because tomorrow, the distant Toth civilization will arrive at this port in a curvature ship!

This is an unprecedented event, and a total of more than a million Torth civilization scientists will come to this star field. This is an exchange between the four levels of civilization, which cannot be ignored, and the elite representatives of almost every industry will participate in this exchange event.

Zhang Yuan couldn't help but feel that the times had changed greatly, in the earth period, human beings had not yet come into contact with aliens, if there were really aliens infested near the earth, human beings might be scared half to death, all kinds of nuclear bombs were taken out, and they were protected tightly......
