The third news is that there are abundant resources nearby, and there are many stars and planets.

There is a red dwarf star 1 light-year away from the two neutron stars, and a yellow dwarf star 1.2 light-years away, and the planet above has liquid water resources. The stars in this region are significantly denser than those in the solar system.

This is good news, neutral to positive.

After humanity and the Torth civilization have completed the entire goal, they still have to prepare to escape the entire range of neutron star collisions.

When the time comes, it would be better for the two civilizations to separate and develop their own.

Since there are so many stars to choose from, it is good for everyone to choose at will, and basically there will not be too much contradiction.

In fact, this is basically within the expectations of scientists, neutron stars are the predecessors of blue dwarfs, and after the blue dwarfs are exhausted, they produce supernova explosions to form neutron stars.

Since there are two neutron stars here, it means that there have been two supernova explosions.

The two supernova explosions basically swept away the life of the surrounding 50 light-year planets, so there is no psychological burden to detonate the collision of two more neutron stars.

Yes, this kind of problem must be considered in advance, if it is really because the neutron stars collide 100,000 years in advance, causing a large number of surrounding civilizations to perish, maybe some fifth-level Holy Mother civilization will come over to find trouble!

On the other hand, supernova explosions also gave birth to a large number of heavy elements, such as gold, silver, copper, iron, and so on. Therefore, the proportion of heavy elements in the surrounding planetary systems will be much higher than that of regular planetary systems......

The higher the density of the planet, that is, the higher the content of metal elements, the more suitable it is for the development of planetary fortresses, this is a certainty.

Zhang Yuan exhaled lightly, this kind of expected thing is not surprising, but there is still a faint sense of excitement in his heart.

Ready-made metal planets are the best choice for developing battle stars, which is equivalent to a ready-made super iron bump, unlike Earth, which also has structures such as crust, mantle, and core.

Of course, the development of battle stars does not mean that it can be developed with ready-made materials, but also requires sufficient scientific and technological strength and a lot of time accumulation.

At present, on this leased planetary fortress, there are dense large-scale engineering equipment, which is purchased for it, and it costs the boss a lot of points!

In addition, there is a fourth piece of news, which is a specific astronomical report in the "neutron star-neutron star" binary star system.

The neutron star is only a dozen kilometers in size, yes, only a dozen kilometers, and it looks about the same size as the Brilliant Galaxy.

What is the concept? Compared with the diameter of 12,000 kilometers of the earth, it is just a small point, and compared with the diameter of 1.4 million kilometers of the sun, it is like the sesame seeds next to a watermelon, you can't see it!

But its power is amazing, and its mass is greater than that of the sun!

The smallest neutron star is also 1.4 times more massive than the Sun! Concentration is the essence, if the earth is scratched by a neutron star, or even without scratching, a little gravitational force can completely tear the earth apart.

Due to their high speed around each other, the center of mass of the two neutron stars is actually in a point of void in the middle line. Therefore, from the perspective of a simple physical model, all the stars equivalent to the entire binary star system revolve around this center of mass in the void and are a stable system.

There are an astonishing number of planets inside, and there are more than 60 terrestrial planets larger than the moon!

And most of them are very young and lively, and there are quite a few Jupiter-like planets, which are distributed within 20 astronomical units.

These Jupiter-like planets are relatively far away from binary star systems, but they are very large, probably due to the large amount of hydrogen absorbed by the first two supernovae. They will be a very good arsenal of nuclear fuel.

Zhang Yuan focused on terrestrial planets that had the potential to be transformed into planetary fortresses.

Because these terrestrial planets are relatively young, they should not be more than 1 billion years old, and various volcanic eruptions and earthquakes are frequent, which means that if the core of a planet is likely not completely cooled, it will make various engineering difficulties increase countless times.

Volcanic eruptions and earthquakes are powered by the nuclear fission of radioactive materials at the core of the planet, and no matter how high the level of human beings is, it is impossible to prevent the spontaneous nuclear fission of these heavy elements.

When he saw these materials, one of the professors said worriedly: "No, the inner shell of these planets has not been completely cooled, and it is full of magma, so it is not suitable to be used as a planetary fortress." ”

“…… Because under the super thrust of the planetary engine, the normal plate cannot support this push at all, and soon the entire continent will be shaken to pieces, causing the planetary engine to be damaged. ”

The crust of the planet is as fragile as the egg membrane on the surface of an egg, and this membrane alone cannot support the mass of the entire planet.

The structure of the planetary engine must go at least tens or even hundreds of kilometers deep, all the way to the mantle layer below, and it can barely be stabilized.

This means that you have to choose a metal planet with a completely cooled core.

However, it is impossible to figure out which planet has completely cooled down and which planet is still active, and it will be necessary to conduct field investigations when the time comes.

There is not much time to be able to go on a field trip, only a month at most.

"This battle star under our feet will only continue to be leased for another month, and when the lease time is up, it will return, and there will be no room for regrets. Time is of the essence. ”

Zhang Yuan couldn't help but have fine beads of sweat on his forehead, which may be the most important choice in thousands of years of human beings. Once you choose the wrong path, the future will be quite painful, not only for their generation, but also for the next ten or twenty generations.

After reading these objective conditions, scientists from both civilizations began to make suggestions, using these astronomical data to calculate the volume, density, mass, magnetic field, and so on of these planets.

The higher the density, of course, the better, and the higher the density. But the mass of such a planet cannot be too large, the mass is large, and it will be troublesome to promote, and it is better not to exceed a third of the mass of the moon.

You can even opt for a completely frozen hockey ball, a place where there are no serious stars, and the intensity of the light emitted by the two neutron stars is so weak that the planets here are generally below minus 250 degrees Celsius!

It is also a good choice if you choose a large ice hockey ball that is completely frozen to develop a planetary fortress. Anyway, this thing is only a one-time thing, and people don't care if it can be used for a long time.

With such careful selection, a total of six planets with a probability of more than 80% of the conditions were found.

When the time comes, we will have to go on a field trip.

Next, the two sides announced their maximum production capacity, promising to expand the population in the future, at least how much production capacity will be allocated for the construction of planetary engines.

Yes, in the future, there will be a population expansion, and whatever the plan is, it will have to expand the population, and it will have to reduce the development of all walks of life, whether it is technology, industry, or social mobilization. All these years of preparation have not been done in vain.

Zhang Yuan breathed a sigh of relief and listened to the scientists on the stage introduce the backup plans one by one.

“…… Propulsion of a planet with a mass comparable to 20% of the moon requires the construction of at least 30,000 planetary engines, which can theoretically be completed in 1200-1500 years according to the current productivity of both sides and the productivity of the two civilizations...... That's 30 planetary engines built every year. ”

Theoretically, it's so fast, after all, the mechanical tools that cover the entire battle star are not bought for nothing, and the most important thing is the problem of execution.

In fact, this is a very crude way, people just install planetary engines on the planet, and all kinds of miscellaneous functions such as weapon functions and ecological functions are not needed, this kind of planet is only moving at most, not a real "battle star", but it undoubtedly reduces a lot of time.

It's going to be scrapped eventually, and there's no need to make it too elaborate.

And people's food, clothing, shelter and transportation will still be in the spaceship.
