Chapter 535

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

There is a red dwarf one light-year away from two neutron stars, and a yellow dwarf one.2 light-years away. The planet above has liquid water resources.. The stars in this region are obviously denser than those in the other side of the solar system.

That's good news. The neutral side is positive.

After human beings and Toth civilization have completed the whole goal, they still need to prepare to escape the whole scope of neutron star collision.

At that time, it would be better for the two civilizations to separate and develop their own civilization.

Since there are so many stars to choose from, you can just choose them at will. Basically, there won't be much conflict.

In fact, this is basically within the expectation of scientists. The predecessor of a neutron star is a blue dwarf star. After the life of a blue dwarf star is exhausted, a supernova explosion will form a neutron star.

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

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

Yes, this kind of problem must be considered in advance. If the collision of neutron stars 100000 years ahead of time leads to the extinction of a large number of surrounding civilizations, maybe some level 5 Notre Dame civilizations will come to trouble!

On the other hand, the supernova explosion also produced a large number of heavy elements, such as gold, silver, copper and iron. Therefore, the proportion of heavy elements in the surrounding planetary system will be much higher than that in the conventional planetary system

The higher the density of the planet, that is, the higher the content of metal elements, the more suitable for the development of Planetary Fortress.

Zhang Yuan gently breathed a breath, this kind of expected things, but also no good surprise, but, still had a faint sense of excitement in the heart.

A ready-made metal planet is the best choice for developing a war star, which is equivalent to a ready-made super iron knot. Unlike the earth, there are structures such as crust, mantle and core.

Of course, the development of war star 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, there are a lot of large-scale engineering equipment on the planet fortress, which is purchased for this purpose. It costs a lot of points!

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

Neutron star is only ten kilometers in size. Yes, it's only ten kilometers in size. It's about the same size as bright galaxy.

What is the concept? Compared with the diameter of 12000 kilometers of the earth, it's just a small point. Compared with the diameter of 1.4 million kilometers of the sun, it's like a sesame beside a watermelon. You can't see it!

But its power is amazing, the mass is bigger than the sun!

The smallest neutron star is 1.4 times of the sun! Concentration is the essence. If the earth is scraped to the surface by neutron stars, even without scratching, a little gravity can tear the earth to pieces.

Due to the high-speed rotation between the two neutron stars, the center of mass of the two neutron stars is actually in the void at a certain point of the middle line. Therefore, from the point of view of simple physical model, all stars of the whole binary system revolve around the center of mass in the void, which is a stable system.

There are more than 60 earth like planets, which are bigger than the moon!

And most of them are very young and lively. There are also many woodlike planets, which are distributed within 20 astronomical units.

These wooden planets are far away from the binary system, but they are very large, which may be caused by the absorption of a large amount of hydrogen in the first two supernovae. They will be a very good nuclear fuel bank.

Zhang Yuan focused on the earth like planets that could be transformed into planetary fortresses.

Because these earth like planets are relatively young, they should not be more than 1 billion years old, and all kinds of volcanic eruptions and earthquakes are frequent. In other words, if the core of a planet is not completely cooled, it will increase the difficulty of various projects by countless times.

The energy of volcanic eruptions and earthquakes comes from the nuclear fission of radioactive materials in the core of the planet. No matter how high the human level is, it is impossible to prevent the spontaneous nuclear fission of these heavy elements.

When he saw the information, one of the professors said anxiously, "no, the cores of these planets are not completely cooled. They are full of magma, so they are not suitable to be used as planetary fortresses."

“…… Because under the super strong driving force of the planetary engine, the normal plate can't support this kind of driving force at all, and soon the whole continent will be shattered by the earthquake, leading to the damage of the planetary engine. "

Compared with the whole planet, the crust of the planet is as fragile as an egg membrane on the surface of an egg, which alone cannot support the mass of the whole planet.

The structure of the planetary engine has to be at least tens or even hundreds of kilometers deep, until the mantle beneath it is barely stable.

That means you have to choose the kind of metal planet whose core is completely cooled.However, it is impossible to find out which planet has been completely cooled and which is still active from a distant astronomical observation here, and we have to make field investigation at that time.

There is not much time for on-the-spot investigation, only one month at most.

"The War Star under our feet will only continue to lease for one month. When the lease time arrives, it will return and there will be no room for regret. Time is pressing. "

The sweat on Zhang Yuan's forehead is probably the most important choice in thousands of years. Once you choose the wrong path, the future will be very painful, not only for their generation, but also for the next ten or twenty generations.

After reading these objective conditions, the scientists of the two civilizations all began to make plans to use these astronomical data to calculate the volume, density, mass, magnetic field and so on of these planets.

Of course, the higher the density, the better, the higher the density. But the mass of this kind of planet can't be too big. If it's too heavy, it's troublesome to push it. It's better not to exceed one third of the mass of the moon.

There are no serious stars in this ghost place. The light intensity of the two neutron stars is so weak that the stars here are generally below minus 250 degrees Celsius!

If you choose a completely frozen ice hockey to develop Planetary Fortress, it is also a good choice. Anyway, it's only one-time. People don't care if it can be used for a long time.

Under such careful selection, we found six planets with a probability of more than 80%.

We'll have to make field trips.

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

Yes, it is true that we need to expand the population in the future. No matter which plan, we have to expand the population and reduce the development of all walks of life, whether it is in science and technology, industry or social mobilization. All these years of preparation are not in vain.

Zhang Yuan breathed a sigh of relief and listened to the scientists on the stage introducing alternative plans.

“…… To propel a planet with a mass equivalent to 20% of the moon, at least 30000 planetary engines need to be built. According to the current productivity of both sides and the productivity of two civilizations, theoretically, it can be completed in 1200-1500 years That's 30 planetary engines a year. "

Theoretically, it is so fast. After all, the mechanical tools that cover the whole war star are not bought for nothing. The main problem is the implementation.

In fact, this is a very rough way. People just install planetary engines on the planet. They don't need all kinds of miscellaneous functions, such as weapons function, ecological function and so on. This kind of planet can only move at most. It's not a real "War Star", but it undoubtedly reduces a lot of time.

It will eventually be scrapped, there is no need to make too delicate.

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