Chapter 430: Standards for a Perfect Planet

For example, a strong magnetic field. The magnetic field of the wandering blue star is caused by an iron core, which originates from sufficient geothermal energy generated by the planet during its birth.

Over a long period of time, elements of different weights and densities gradually separated into a solid inner core and a liquid outer core. The continuous flow of charged elements maintained the Earth's magnetic field. The magnetic field blocks most of the radiation from the star and is a necessary condition for the survival of organisms. Therefore, a "perfect planet" must have been born and developed under similar conditions.

In addition, proper plate tectonics is a hidden condition for the birth of life. On the wandering blue planet, plate tectonics is caused by the slow movement of the viscous mantle between the crust and the core. In plate tectonics, the crustal plates are constantly pulled, pushed and reshaped, thus shaping the deepest oceans, the highest mountains and everything else on the wandering blue planet.

Plate tectonics creates thousands of unique habitats with different temperature, moisture and soil conditions, encouraging life to develop in many directions. Plate tectonics is also an important force that maintains the climate of the wandering blue planet - through the carbon cycle. In the carbon cycle, carbon-rich minerals slowly seep into the mantle and then return to the surface through volcanic activity.

This cycle balances the amount of carbon dioxide in the atmosphere, and thus the climate of the rogue blue planet, for millions of years. Without this indispensable thermostat, the rogue blue planet would not be as habitable as it is today.

Another thing to remember is that while there may be other planets that are more suitable for nurturing life than rogue blue planets, they cannot be more suitable for rogue blue planet life than rogue blue planets.

Although this sentence sounds a bit confusing, it can be understood by giving an example. The planets located in the habitable zone of an orange dwarf star receive different stellar light than the solar light received by a wandering blue star. In order to make the most of sunlight on the wandering blue star, most plants have green leaves. But on the "perfect planet" of an orange dwarf star, what will the plants look like? Will they be blue, purple or black!
If the plants on the "perfect planet" are so different from the plants on the Wandering Blue Star, can the animals be the same as the animals on the Wandering Blue Star!

So, can the humans on the Wandering Blue Planet live normally on these "perfect planets"? From this perspective, the Wandering Blue Planet is still a unique and perfect planet for humans.

This is like Pandora. Although the carbon dioxide content on Pandora exceeds the standard, the wandering blue planet humans who have not been strengthened by genetic enhancement drugs cannot survive directly, but the Na'vi and other animals can survive well. Therefore, although Pandora looks very beautiful, it is not perfect for the wandering blue planet humans.
Therefore, the selection criteria for the perfect planet for humans have been basically perfected.

The first point is to be in the habitable zone of the parent star with a suitable lifespan; about 10% larger than the wandering blue star, such a planet will be 50% heavier than the wandering blue star and have a gravity of 25% greater; the average temperature is preferably five degrees higher than the wandering blue star, so that life can thrive all over the world.

Second, a better atmosphere would contain 25 percent oxygen, rather than the 21 percent on today's wandering blue planet; ideally, the land and oceans would be widely distributed, providing organisms with abundant shallow coastal areas where biodiversity is higher.

Such a perfect planet naturally exists. Although the requirements seem to be many, the universe or the Milky Way is too huge. The planet Origa VI, which is suitable for human habitation and where the Wandering Blue Star is going next, is naturally such a perfect planet suitable for human habitation.

In the end, Tu Hengyu and others followed Liu Xiu's decision and left the Covenant to its fate, while the Wandering Blue Star also began to adjust the angle of its advance according to the sailing direction obtained from the Covenant spacecraft.

There is no way to follow the instructions on the star map. The direction in which the Wandering Blue Planet is heading is not the same as the location of Planet Origa VI.

For a massive planet like the Wandering Blue Star, whose mass exceeds six hundred trillion tons, changing its angle is quite difficult.

It took only six years for the Wandering Blue Star to reach the planet Origa VI in 2110. It should be noted that according to the original estimate, the Covenant spacecraft would take more than seven years to reach Origa VI.

There is no way because although the Covenant spacecraft is faster than the Wandering Blue Star in terms of regular speed, it needs to replenish energy. Therefore, in terms of total sailing time, it is not as fast as the Wandering Blue Star. After all, the Wandering Blue Star has sufficient resource reserves and does not need to stop and rely on the star system to replenish energy.

Of course, although the Wandering Blue Star seems to have many advantages, it also has many disadvantages. For example, the Luoxi Limit is a big hidden danger, which prevents the Wandering Blue Star from getting close to the star system or other massive planets like ordinary spacecraft.

In fact, Liu Xiu was not very satisfied with the thrust of the planetary engine. You know, although the thrust of the planetary engine looks very large, it has a thrust of 15 billion tons.

Today, there are 22,000 planetary engines on the entire Wandering Blue Planet, excluding 2,000 steering engines. Therefore, the thrust provided by the 20,000 planetary engines used to propel the Wandering Blue Planet together can reach a total thrust of 300 trillion tons.

However, such a huge thrust is not enough when applied to a wandering blue planet with a total mass of 600 trillion tons, because the thrust-to-weight ratio is too low, too low.

Precisely because the thrust-to-weight ratio is so low, when the wandering blue planet was leaving the solar system, it had to rely on Jupiter's gravitational slingshot to accelerate it in order to escape the gravity of the sun.

And because of the low thrust-to-weight ratio and difficulty in acceleration, they had to rely on the oxygen explosion in the atmosphere of the wandering blue planet to resolve the Jupiter crisis.

You must know that no matter whether it is the current space fighter or the previous fighter in the atmosphere, one of the most critical indicators to measure the quality of a fighter is the thrust-to-weight ratio.

For example, the famous first fifth-generation Raptor fighter has a thrust-to-weight ratio of 0.84. It is precisely because of such a high thrust-to-weight ratio that the Raptor fighter can perform various fancy flying skills.

In comparison, ordinary transport aircraft have a thrust-to-weight ratio of only 0.2 to 0.3, which is why they appear very clumsy when flying.

The same situation applies to a wandering blue planet. The extremely low thrust-to-weight ratio causes the wandering blue planet to accelerate extremely slowly, making it impossible for it to escape the capture of various stellar gravity. Therefore, unless necessary, the wandering blue planet will not approach other star systems.

Of course, Liu Xiu was not the only one who was dissatisfied with the mobility of the Wandering Blue Star. Liu Qi was also very dissatisfied with the mobility of the Wandering Blue Star.

So when the Wandering Blue Star arrived at the star system where the planet Origa VI was located, Liu Qi submitted a plan.

This plan states how to improve the mobility of the wandering blue planet. It also states that the thrust of the planetary engine can be increased by more than a hundred times.
