Chapter 544

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

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

This is a fairly good good news, neutral bias is good.

After mankind and the TOS civilization have completed the whole big goal, they still have to prepare to escape the scope of the whole neutron star collision.

At that time, the two civilizations had better separate and develop their own.

Since there are so many stars to choose, just choose them at will, and basically there will be no great contradiction.

In fact, this is basically within the expectations of scientists. The predecessor of neutron stars is blue dwarfs. After the life of blue dwarfs is exhausted, they will 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 cleaned up the life of the surrounding stars 50 light-years away. Therefore, there is no psychological burden to detonate the collision of two neutron stars.

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

On the other hand, the supernova explosion 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 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, which is certain.

Zhang Yuan gently breathed a sigh. There was no surprise in this expected thing, but there was still a faint sense of excitement in his heart.

The ready-made metal planet is the best choice for the development of war stars. It is equivalent to a ready-made super iron pimple. Unlike the earth, it also has the structure of crust, mantle and core.

Of course, the development of war star does not mean that it can be developed with ready-made materials. It also needs sufficient scientific and technological strength and a lot of time accumulation.

At present, on the leased Planetary Fortress, numerous large-scale engineering equipment is purchased for it. It took the boss a sum of points!

In addition, the fourth news is the specific astronomical report in the "neutron star neutron star" binary system.

Neutron star is only a dozen kilometers in size. Yes, it is only a dozen kilometers, about the same size as the bright galaxy.

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

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

The neutron star with the smallest mass is also 1.4 times that 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 each other, the centroids of the two neutron stars are actually in the void at a certain point of the middle line. Therefore, from the perspective of simple physical model, all stars equivalent to the whole binary system rotate around this point of mass center in the void, which is a stable system.

The number of planets inside is amazing. There are more than 60 earth like planets larger than the moon!

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

These wooden like planets are far away from the binary system, but their volume is 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 focuses on earth like planets that may be transformed into planetary fortresses.

Because these earth like planets are relatively young, their age should not exceed 1 billion years. Various volcanic eruptions and earthquakes are frequent. In other words, if the core of a planet is likely not completely cooled, it will increase the difficulty of various projects 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 level of human beings is, it is impossible to prevent the spontaneous nuclear fission of these heavy elements.

When seeing these materials, one of the professors said with worry: "no, the cores of these planets have not been completely cooled. They are full of magma, so they are not suitable to be used as planetary fortresses."

"... because under the strong driving force of the planetary engine, the normal plate can't support this driving at all, and soon the whole continent will be shattered, resulting in damage to the planetary engine."

Compared with the whole planet, the crust of the planet is as fragile as an egg film on the surface of an egg. This film alone cannot support the quality of the whole planet.

The structure of the planetary engine must be at least tens or even hundreds of kilometers deep until it reaches the lower mantle layer.

That means that we must choose the kind of metal planet whose core has completely cooled.

However, in the distant astronomical observation here, it is impossible to find out which planet has completely cooled down and which planet is still active. Field investigation will have to be carried out at that time.

There is not much time for field investigation, only one month at most.

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

Zhang Yuan's forehead can't help but burst out fine beads of sweat, which may be the most important choice of mankind for thousands of years. Once you choose the wrong path, the future will be very painful, not only their generation, but also the next ten or twenty generations.

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

Of course, the higher the density, the better, the higher the density. However, the mass of this planet can not be too large. If it is large, it will be troublesome to push it. It is best not to exceed one-third of the mass of the moon.

You can even choose a completely frozen ice hockey. There are no serious stars in this ghost place. The light intensity from the two neutron stars is so weak that the planets here are generally below minus 250 degrees Celsius!

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

So carefully selected, a total of six qualified planets with more than 80% probability were found.

There will be a field trip.

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

It is true that in the future, the population will indeed be expanded. No matter which scheme, the population will have to be expanded, and the development of all walks of life will have to be compressed, whether 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 schemes.

"... to promote a planet with a mass comparable 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 the two civilizations, they can be completed in 1200-1500 years in theory... That is, 30 planetary engines can be manufactured every year."

In theory, it is so fast. After all, the mechanical tools covered with the whole war star are not bought for nothing. The most important thing is the problem of execution.

In fact, this is a very rough way. People just install planetary engines on the planet. All kinds of miscellaneous functions such as weapon function and ecological function are not needed. This kind of planet can only move at most, not a real "War Star", but it undoubtedly reduces a lot of time.

It will eventually be scrapped. There is no need to make it too delicate.

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