After hanging around in the cave for more than ten days, it only took twenty hours for him to handle the official duties passed from the royal city. It seemed that sooner or later his territory would be able to operate automatically.
It was night when I came out of the underground world.
The wind direction is about right and the night sky is very clear today.
but……
"What is that?" Li Xiang always did the same thing as Wang Qi. He looked up at the sky, and she looked at it too.
Wang Qi followed the direction Li Xiang pointed and saw a broom star.
"A comet, a mixture of stone and ice, is struck by the sun and the ice sublimates and forms a comet tail that reflects light."
Although he didn't quite understand, Li Xiang still said "oh".
Wang Qi was not so cool. Staring at the comet, he suddenly remembered Solaris' words.
The sky will give the answer, could it be this guy?
Comets are very special existences, almost completely different from asteroids.
Because of the energy of the star, it is almost impossible for asteroids that exist in the main light belt to leave ice. Only comets that spend most of their time outside the main light belt can keep ice.
This is not the solar system, but the basic characteristics of light have not changed. It will never be at a position of tens of au. The energy of sunlight is still the same as within 1 au. As long as it is far enough away, a comet of a certain mass will have the opportunity to use gravity to replenish free water.
For example, assuming that the orbit of a comet is closest to the star, it is 0.1 au, and the farthest is 80 au. When the distance is far away, the relative speed of the comet will be slower than the star. Then, more than 99% of the time, its position is beyond 10 au. In less than 1% of that time, a comet tail forms.
Knowing the main activities of comets, we know that the chance of encountering a visible broom star is very small.
Apart from such iconic things as comets, is there any other answer to the sky?
Earth's axis suddenly shifted causing polar night? There is a chance of it happening, but most of it has nothing to do with the sky.
Some kind of sky message created by magic? This is beyond Wang Qi's knowledge, and he can only realize it after seeing it.
The Riddler is so annoying.
Wang Qi scratched his head and led Li Xiang back on foot. The accompanying garrison did not dare to disturb him, and those behind him who opened the way were all dozens of meters away.
After returning to the royal city to rest for a while, he immediately arranged for people to investigate the comet's situation.
It sounds simple, but when you lack a clue, there are many directions that can provide help.
First, look for the indigenous people of this world to see if anyone knows the name, period, etc. of this comet.
Secondly, the profession of astrologer exists in the Night Clan. Even if it only existed at the time of Wang Qilai, there must have been a few people.
The Imperial City is affected by volcanic activity and the visibility of the atmosphere is limited. It would be better to go to Red Rock City or the cave area.
I don’t know what the level of these people is and what results they can achieve. Anyway, I will send them out to stare at the comet first.
The latter part falls within the scope of metaphysics. See if there are any prophecies or similar rumors related to comets. This kind of thing is difficult for the Night Clan and Sharp Blade to deal with, so they can only leave it to big players with relatively developed local connections.
As it turned out, he hadn't even started to contact big companies yet, and the astrologer from the Night Clan sent back urgent reports within a few days.
A comet will hit! ! !
wtf?
There was no specific time in the emergency report. Wang Qi wrote and replied: The specific impact time and impact point are to be calculated as soon as possible.
It doesn’t take an astrologer to know that today is not tomorrow.
The comet revolves around the star, not the world beneath its feet. The distance between this world and the star is not yet known. Maybe we can see half an AU of the comet's tail. At a speed of less than 11 kilometers per second before reaching perihelion, half an AU would take a long time to fly. If the world was still planet-shaped, there might still be tracking drama... or maybe a collision.
What if... what if it really is a geocentric system... In fact, it's the same.
In his previous life, Wang Qi had seen a certain stupid science popularization, which discussed the development of the geocentric theory in detail, and it could even be explained using mathematics. The only difference between the two is that the orbits of heliocentric celestial bodies are all elliptical; while the orbits of geocentric celestial bodies rotate in circles. When the whole body orbits the earth, it will return to the perigee for a period, and the drawn trajectory is similar to a few petals put together.
In short, unless it is a very tiny comet summoned by someone and it is actually very close, the impact in the natural state should still take a certain amount of time.
Although the prospect of a comet impact is serious, life must go on.
Assuming it still has one to three months, all we can do now is build shelters quickly.
Comets and asteroids are very different, and their destructive power mainly depends on their size and shape.
It’s meaningless to say it’s too small, just look at the big one.
The impact of large celestial bodies has a very magical effect. Due to the high speed and large resistance surface, the atmosphere in the area will be compressed, which means that the first impact begins before hitting the ground, and the rapidly pressurized atmosphere will immediately be converted into plasma. It may only be a few tenths of a second before the celestial body hits, but enough life at the point of impact will be completely wiped out.
The second impact, which is also a stone collision in the traditional sense, has a "slightly" larger equivalent. It is counted in tons according to tnt, which means sixteen or seven zeros are appended to the number. As a reference, fission nuclear bombs have five zeros. There are 6 to 7 fusion hydrogen bombs, no matter how big a human being is, they will not be able to control them.
As long as you are not hit face to face, the shock wave generated by the second impact is easy to avoid, because the high-intensity shock wave cannot follow the curve of the ground surface, and the destructive power of the secondary wave is relatively limited.
If good luck is not within the direct impact range of the shock wave, then we will face the third wave of impact, the super volcano effect.
The effect of the super volcano effect is actually not heating, but a massive amount of material being thrown out of the atmosphere. Some of them will become satellites created by the impact, traveling around the world outside the atmosphere, and many small particles will float in the atmosphere for a long time.
The direct effect is to reduce the amount of sunlight.
And once the sunshine balance is destroyed, the next step will be bad.
First, a large amount of vegetation died, herbivores and carnivores collapsed one by one through chain propagation, and fungi took over the entire world.
If it lasts for a long time, the arrival of the ice age is just around the corner. Once the ice age arrives, it will enter a vicious cycle. Even if the atmospheric particulate matter gradually decreases, the surface will be unable to heat up due to the reflection of large areas of ice and snow, and may even become colder and colder. The world turns into a snowball.
Solaris probably doesn't want everyone to see the end of the world.
If there is a way to survive, it is that the comet is not big enough, or there is something wrong with its shape.
Although many comets and asteroids only have one name, they are a lot of small things moving together by gravity. Even if the total tonnage is relatively large, this form cannot eject a sufficient amount of material outside the atmosphere, and the subsequent impact will be small. a lot of.
In short, dig a hole quickly and build a railway to the underground caves. As long as you avoid the first impact, there will be time to solve the subsequent problems.
In terms of food, we mainly rely on sugar reserves.
Sugar will not go bad, and it doesn’t matter even if the sun cannot be seen for ten or eight years after the impact. As long as the first wave of impact survives, all the nutrients in the royal court will be used to make sugar, but I don’t know if there will be enough light by then.
The same cannot be said for soybeans and wheat. The light that is partially blocked by volcanic ash is already at its limit. No matter how low the brightness is, it cannot grow just by relying on the ambient temperature. Leeks can grow into leek yellow in a dark environment, but not.
Meat is also a resource that cannot be regenerated if eaten in a short period of time. Xiaoqiang is very strong, but he doesn't know if he can collect enough fermented sawdust after the comet hits.
Perhaps we should also try to make use of the ecosystem of acidophilic microorganisms and sea anemone lichens in underground caves, and first study whether those things can be cultivated artificially.
