Beneath Deep Space

"...Helium-3 is a good thing. It is not only an energy source, it can also be used to do certain superfluid experiments, and it can fit the formation of cosmic strings to a certain extent..."

"And elemental helium-3 is an inert gas that is difficult to react chemically with other substances...it is also very helpful for many experiments."

When talking about helium-3, physicist Professor Ding Yidong came up with a series of strange terms.

He was still thinking about his science experiment.

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

Various theories are emerging one after another, and human technology is also booming.

The great scientist felt that... the meeting here was a waste of time. He wanted to go back to his laboratory.

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

Especially after the brain chip was installed and the intelligence made a leap... everyone felt that they had broken through to another level.

The activity of people's thinking has been greatly enhanced, and fantastic ideas are emerging one after another. It would be a pity not to do scientific research...

One of the engineers made a useful point: "If helium-3 is used instead of deuterium as the main nuclear fuel, the nuclear reaction will be cleaner. Without the neutron flow, the maintenance interval of the nuclear reactor can be increased by 18 times! This is a big deal for us. beneficial."

"And the helium-3 bomb has a smaller yield and can be carried out in a smaller reactor..."

Now humans have indeed achieved nuclear fusion, but they have directly used a reactor several kilometers thick, coupled with a strong magnetic field, to roughly absorb the energy of nuclear explosions directly.

This kind of reactor also requires certain maintenance after long-term operation.

The neutron flow produced by nuclear reactions is even more annoying. Neutrons themselves are not charged and cannot be isolated by magnetic or electric fields. These neutrons mixed in the ions will not only damage the furnace wall, but also damage the related equipment of the generator, greatly increasing the maintenance work.

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

"Even...higher-level interstellar civilizations also need helium-3, and it is also a trading target among civilizations."

Everyone was discussing heatedly, and mining helium-3 became the top priority.

Of course, this matter cannot be regarded as a long-term work plan. With the massive robots stored in Noah, the mining work can be completed within a few years.

So, what should humans do in a few years?

Now that humans have become an interstellar civilization, the areas they can set foot in are even wider, and there are too many targets to choose from.

But people cannot wander around like headless flies. There are many things that people must figure out: First of all, of course...how should new human civilization develop?

How should human beings who have just stepped into the interstellar face the entire universe? Or...how to face a galaxy full of secrets? How to explore the outside world?

Although people have learned some basic information about the universe from the report of the alien life form "Black", this information is still too little.

Yu Yifeng thought for a while and said directly: "It is too dangerous to wander aimlessly in the galaxy like this."

"So I think that if there is a parent star similar to the earth, or a sun as a backing, and then exploring around, it will undoubtedly be more in line with our thinking logic."

"...For now, our primary goal is: to find the next Earth, to find the next solar system!"

"What do you think?"

This plan was unanimously approved by everyone present.

Every first-generation old man longs for another earth. Maybe it's because they are getting older and time has passed, and they inexplicably miss some of the days on earth.

"In half a year, we will arrive at the planet GB131, and the mining time will be about two years. What suitable targets do you have to choose from next? Have we discovered any planets similar to the Earth? The ones that are closer." Yu Yifeng asked while studying the star road map sent by Green Light Civilization.

The information above is not very much, it just marks a star more than 4,000 light-years away, in the outer area of ​​the core of the Milky Way...

That should be the star colonized by the Green Lanterns.

The green light people still owe humanity something that they haven’t repaid...

However, it is impossible for humans to go so far to blackmail the Green Lanterns for the time being.

Judging by the size of the spaceship alone, human technology is still inferior to the Green Light Civilization... If you run over to ask for debts, you will be beaten!

Astronomer Thomson was the first to propose: "The binary star system we are in does not have an ecological environment like the Earth... so we must leave this star system."

He was operating the computer, and a relatively complex image popped up on the screen, which was the orbit of the binary stars.

For the two-body problem in the universe, if we only consider universal gravitation and take one star as the reference system, the motion trajectory of the other star will be a conic orbit.

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

Although this kind of conic trajectory is simple to calculate, it is too unstable for a living planet, sometimes far and sometimes near, sometimes hot and cold. Coupled with the massive and powerful solar wind from the binary stars, it can directly blow away all the atmospheres of the nearby planets.

Therefore, all planets in the binary star system do not meet human requirements.

Professor Thomson said: "We have observed that there is a sun-like star 6.3 light-years away from here, and there may be an Earth-like planet in the habitable zone. We can go there to try our luck, and if it doesn't work, we can also try to modify it ourselves. one time……"

"I just don't know if there is any indigenous civilization there..."

"There are other terrestrial planets further away. This is the specific information... you can take a look."

He sent a piece of information to everyone's computer.

Yu Yifeng glanced briefly, nodded and said: "That's it. During this period, we will first conduct detailed observations of the Earth-like planet and analyze the specific data. After we have finished replenishing helium-3, we will do the final resolution……"

This short meeting ended like this. Of course, it was just a preliminary meeting to let everyone know about the recent goals:

Mine first, then find the next Earth!

Yu Yifeng suddenly felt a little emotional, there is a planet 6.3 light years away, a distance that people on Earth could not even imagine in the past!

But according to the current maximum speed of curvature navigation, which is almost two years of sailing time, it is completely acceptable to humans.

In just two years... humans can get over it.

This is...the qualitative change brought about by technology!

"If the quality of that planet is really poor and it will take hundreds or thousands of years to transform, it would be better to just give up and look for the next one."

Yu Yifeng thought silently.

"The Milky Way is so big, there is no way there won't be another Earth..."

Having said that, it is still a bit difficult to find one that is exactly the same.

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

Comparing an ordinary terrestrial planet with a nearby hot host star, the reflected light of the planet is greatly obscured by the star, just like a firefly and a bright moon, and humans can easily ignore it.

This is also a natural protection method for low-level civilizations.

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

However, Yu Yifeng knew in his heart that if it was really similar to the earth, life would most likely exist. In the universe, because of the existence of the universal law of life, humans are not lonely. There are too many intelligent life forms other than humans.

However, human beings have been very "lucky", or very "hardworking", and have become a rare interstellar civilization. Interstellar civilizations that have crossed the Great Filter are definitely rare.

If divided by scientific and technological levels, basically more than 99.999999% of civilizations are low-level civilizations. There is no doubt about this!

If we refer to the information given by "Black", these civilizations are simply classified as "K-level civilization", which means low-level civilization.

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