“Helium-3, good thing, not just an energy source, but also for some superfluid experiments, which can fit the formation of cosmic strings to a certain extent...”

“And mano-partic helium-3 is an inert gas that is difficult to chemically react with other substances ... and is also very helpful for many experiments.”

Talking about helium-3, physicist Professor Ding Yidong said a strange string of words.

He was still thinking about his scientific experiments.

Until now, the golden life of physics has not passed, and there are still a lot of difficulties that have not been overcome.

Various theories emerge, and human technology is also booming.

The big scientist felt that ... meeting here was a bit of a waste of time, and he wanted to go back to his own laboratory.

After 160 years of hard work, these work habits are engraved in people's bones.

Especially after the brain chip is installed, the intelligence has taken a leap... everyone feels that they have broken through to another level.

The activity of people's thinking has greatly increased, and whimsy ideas have emerged in an endless stream, and it is a pity not to do scientific research...

One of the engineers made a useful point: “Nuclear reactions are cleaner if helium-3 is replaced by detonation as the primary nuclear fuel.”Without neutron flow, the maintenance interval of the nuclear reactor can be increased by 18 times!This is good for us.”

“And the helium-3 bomb is less equivalent and can be carried out in a smaller reactor...”

Now humans have indeed achieved nuclear fusion, but they are directly using a reactor with a few kilometers thick, coupled with a strong magnetic field, which crudely eats the nuclear explosive energy directly.

This kind of reactor operation for a long time also requires a certain maintenance.

The neutron flow generated by the nuclear reaction is more annoying, the neutron itself is not electric, and cannot be isolated by a magnetic field or electric field.These neutrons are mixed in the ion, which will not only destroy the furnace wall, but also destroy the relevant equipment of the generator, making the maintenance work greatly increased.

If helium-3 is used as nuclear fuel, it will not produce neutrons, and it is indeed much cleaner and more efficient.

“Even ... higher-level interstellar civilizations require helium-3, which is also a trading object among civilizations.”

There was a heated discussion that the mining of helium-3 became the first major event.

Of course, this matter can not be used as a long-term work plan, with the massive robot stored in Noah, the mining work can be completed in a few years.

So what should humans do in a few years?

Now that humanity has become an interstellar civilization, the area that can be dabbled in is wider, and there are too many choices.

But people can’t turn around like headless flies, and there are many things that people have to figure out: First of all, naturally... how should the new human civilization develop?

How should humans who have just entered the stars face the entire universe?Or... how to deal with a galaxy full of secrets?How to explore outside?

Although some basic information about the universe has been learned from the "black" report of extraterrestrial life, this information is still too little.

Yi Feng thought about it and said, "It's too dangerous to wander aimlessly in the galaxy."

“So I think it would certainly be more in line with our logic to think if there was a parent star similar to Earth, or a sun to back and explore again.”

“For now, our primary goal is to find the next Earth, to find the next solar system!”

“What do you all think?”

This program has won the unanimous approval of all present.

Every first generation of old people is very eager for another earth.Perhaps they are old, for a long time, and they miss some days on earth.

“In half a year, we will reach planet GB131, and the mining time will be about two years.What are the right goals for everyone to choose?Are we Earth-like planets we have found?The kind that is closer.”Yu Yifeng asked while studying the star road map that the green light civilization had sent.

The above information is not much, but it is marked with a star more than 4,000 light-years away in the outer region of the core of the Milky Way.

It must have been the colonized star of the Green Light.

The green man still owes nothing to mankind.

However, it is impossible for humans to go so far to extort green light people.

Just by the volume of the spacecraft, human technology is still not as good as the green civilization... running through the debt is to be hanged!

Astronomer Thomson first proposed: "We are in this binary system, there is no such thing as Earth ... so we have to leave this star system."

He operated the computer, and the screen jumped on a more complex image, which is the orbit of the binary star.

The two-body problem in the universe, if only gravity is considered, takes one star as the reference system, and the trajectory of the other star is the conical curve orbit.

Only in this way can the law of gravity be met with equality.

Although this cone curve trajectory is simple to calculate, it is too unstable for the living planet, far away and near, cold and hot.Coupled with the strong solar wind of the double star, it can directly blow away the atmosphere of the nearest planet.

Therefore, all the planets in the binary system do not meet the requirements of humans.

Professor Thomson said: "We observed that 6.3 light-years away there is a sun-like star, and there may be a terrestrial planet in the habitable zone.We can go there to explore luck, and we can’t really try to reinvent ourselves.”

“I just don’t know if there’s an indigenous civilization there.”

"There are other Earth-like planets farther away, and that's the specifics ... you can see."

He sent a message to each person’s computer.

Yu Yifeng gave a few cursory glances and nodded, “Then, during this time, we will first make detailed observations of the Earth-like planet and analyze specific data.”When we have finished helium-3, we will make the final decision...”

This short meeting ended like this, of course, only the most preliminary meeting, to let everyone know the recent goals:

Mining first, then looking for the next Earth!

Yu Yifeng suddenly felt a little, 6.3 light-years away from the planet ah, in the past, the earth people did not dare to think of the distance!

However, according to the current maximum speed of curvature, that is, almost two years of sailing time, mankind is completely acceptable.

In two years, humans will be able to run.

This is the qualitative change brought about by technology!

"If the star is too poor in quality, it will take hundreds of thousands of years to transform, it is better to give up and look for the next one."

Yu Feng silently thought.

“The Milky Way is so big, there can be no next Earth.”

Even so, it is difficult to find a completely identical one.

The reflected light of the planet is too weak.It is quite difficult to use radio telescopes to clearly observe distant planets.

In contrast to an ordinary terrestrial planet with a nearby hot host star, the reflected light of the planet is widely obscured by the star, just like the firecrat moon, and it is easy for humans to ignore the past.

It is also a natural way of protecting low-level civilizations.

At a distance of 6.3 light-years, human radio telescopes only know that the planet has an atmosphere on its surface, which may be similar to the Earth, and that is all.

However, Yi Feng knows in his heart that if it is really similar to the earth, life is highly likely.In the universe, because of the existence of universal laws of life, human beings are not lonely, and there are too many intelligent beings except humans.

However, humans have become a rare interstellar civilization, or very hard, very “hard work”.Interstellar civilizations that cross the Great Filter are absolutely rare.

If it is divided by scientific and technological rank, basically more than 99.999999% of the civilization, are low-level civilizations, there is no doubt!

If you refer to the information given by "black", these civilizations are simply divided into "K-level civilizations", that is, the meaning of low-level civilization.

Successful people have similar places, but losers are diverse.In the eyes of interstellar civilizations, it is these K-class civilizations that make up a colorful galaxy.
