The resources of the solar system are finite.

Some scientists have established mathematical models and calculated that under the full use of resources, the upper limit of the population of the solar system is about 1 trillion...... Compared to the total number of human beings today, which is only 11 billion, there is still a lot of room for growth.

But human beings do not exist just to survive, but to need a better life.

Everyone has a villa and a big house.

There is more than one private car.

There are conditions to go to various places for vacation and tourism.

The material is extremely abundant, the per capita annual meat consumption is hundreds of kilograms, the price of vegetables and fruits is cheap, and the food waste rate is more than 30%.

Have good educational resources.

Affordable high-quality medical resources.

Spiritual and cultural products are also abundant, and so on.

For everyone to live a life with these good conditions, the population of the solar system is estimated to be limited to about 100 billion people - if you pursue a high quality of life.

And at the rate of population growth of the human race today.

In the short term of 200 years or the slow of 300 years, the total human population is estimated to increase to 100 billion.

Therefore, it is necessary to start preparing for the development of alien galaxies in advance, and take precautions to expand a larger living space.

The preferred option is to focus on all star systems with heavy elemental planets within 10 light-years of the solar system, which are dominated by light elements that have not had a supernova explosion.

Because carbon, oxygen, nitrogen, iron, silicon, phosphorus, calcium, sodium and other heavy elements necessary for the human body, only at the end of the life of a massive star, a supernova explosion, its internal heavy elements will fuse, generating a large number of heavy elements, constituting the "skeleton" of countless lives

For example, in the solar system, after the explosion of a supernova, the nebula and the debris reconverge, and finally ignite the reborn "second-hand star" again.

Unless the technology of mass-batch synthesis of heavy elements is mastered, the light element star system can only be used as a fuel supply station, and has no value for colonization.

After some observations, astronomers found that of the more than 20 stars in the ten light-years around the solar system, only 8 have heavy element planets.

Just 20 years ago, the China Space Agency launched eight deep-space probes in those eight directions, at a speed of nearly 100 kilometers per second, about hundreds of thousands of years later, they will reach the end point and take some valuable photos.

Hundreds of thousands of years later, won't the daylily be cold?

Fortunately, the Black Hole Group gave its strength, and Wei Ming personally stepped out and successively accelerated 8 detectors larger than a billiard table to 0.2 times the speed of light.

Now, twenty years later, although they have not reached their final destination, they have sent back a lot of high-value image data.

Experts from the Black Hole Space Development Company believe that five of these star systems have interstellar colonization value, because a large amount of water has been found.

As for habitable planets and the like, it's good to be able to find them, and it's equivalent to winning the jackpot.

It doesn't matter if you don't find it, as long as there is water, there is value for immigration, and you can open up and colonize human beings.

Besides.

The scientists of the Black Hole Group also conceived a crazy plan, called the "Interplanetary Migration Train Project".

The plan was to put the migrants in a 100-kilometer-long, skeween, long-flying spaceship with its own fusion reactor that could carry up to 1 million migrants.

When departing, the tail reflector is irradiated with high-energy strong light, which continuously provides thrust acceleration, and the maximum speed can reach 0.1C.

Then rely on the spacecraft's own power to accelerate to the level of 0.3C, and then try to maintain a constant speed.

Every year, Wei Ming throws a round "supply ball" with a mass of 1 million tons, a certain elasticity on the surface, and a speed slightly greater than 0.3C.

At that time, the migrant ship will be able to capture the "supply ball" and have a material source to survive the long voyage.

There is also enough working fluid for deceleration when the finish line is approached.

So!

The migration spacecraft that maintains about 0.3C throughout the migration process, even if it is a star system 10 light-years away, will only arrive in more than 30 years.

And because of the time dilation effect, for the millions of immigrants on the spaceship, it may only take thirty years for them to reach their destination, the new home of mankind.

Thirty years!

Assuming that the average life expectancy of the immigrants on the ship is 300 years, and they only consume a tenth of their lives, and then they are given a new territory with unlimited potential, there is no doubt that this is a very good deal.

One expert even conceived a more extreme "migrant train plan", which would be a little over 10 meters in diameter and 10 kilometers long, carrying 100,000 people each, and accelerating to 0.05C with an ultra-long electromagnetic catapult.

A "powered locomotive" with a nuclear fusion reactor was launched in front, and ten "manned trains" were towed behind, totaling 1 million migrants.

Later, every once in a while, Wei Ming sent a million tons of "supply balls" to the past, or multiple in a short period of time.

Finally, when the destination is about to be reached, the "carriage" structure at the back can be put into the reactor at the head, as a working fluid for deceleration, and even more crowded, 1 million people, crowded in the front two sections of the "train", the congestion level reaches the highest.

But the immigrants also saw the dawn and victory.

The only remaining nuclear fusion "power locomotive", two ten-kilometer-long "migrant trains", as well as tools, equipment, robots and other materials, are enough to build an initial survival base, allowing them to take root on another planet and open up sub-bases of human civilization.

Under this plan, it is like living in a stuffy tank train every day, the quality of life of immigrants is indeed very poor, but it can save 80% of material consumption, the maximum speed can reach 0.5C, and the time can reach the end point in a maximum of 20 years, just like natural childbirth, painful, but short.

Furthermore.

In the design drawings drawn by experts, you will find a huge "nuclear-powered car front" shaped like a bullet, with a long tail dragging behind it, which looks easy to reminisce, and some people even took an unsightly name for the scheme, but it is very vivid.

Within 10 light-years of the solar system.

5 pioneering star systems.

5 sets of interstellar migrant trains.

5 million colonized population.

It will take about 20 years to complete.

The above data constitutes the "Immigration Train Plan".

Today, the Black Hole Group lacks nothing but a sufficient population.

Therefore, this plan can only find the cooperation of Hua in order to take down several colonizable galaxies around it. 1603381607
