MTL - Darkness is Coming-Chapter 658 tiny human

   "This 'big briquettes' will slowly cool down over the millennia after the impact, gradually cooling.

However, a large amount of vaporized ocean and surface material at the time of the impact will form a thick cloud of particles, which will block the heat inside the earth. Because the heat is difficult to dissipate, the temperature of the earth's atmosphere may remain above 400 degrees Celsius for a long time, while the atmospheric pressure exceeds the current standard. Atmospheric pressure hundreds of times, oxygen will also burn out, resulting in Earth's living environment comparable to Venus, the worst environment among the eight planets in the solar system, or even worse.

   In addition, the sputtered material thrown into outer space during the impact will form a wave of bombing for hundreds or even thousands of years after returning to the earth. Until the end of this century of bombing, the earth will usher in a little peace.

After 50,000 to 100,000 years of cultivation, the earth will begin to cool down. Since the entire crust is melting in the catastrophe, after re-cooling, they will melt into a whole, because the ocean evaporates and there is no liquid water as a lubricant. Plate tectonic movement makes it difficult to dissipate the energy of huge geological movements, so that the volcanic movements of the earth will become more frequent and more terrifying.

In another 500,000 to 1 million years, single-celled microbes floating in hot magma may land on land and mutate and evolve over a long period of time, possibly until five billion years later when the sun ages and becomes At the time of the red giant, complex life had not yet evolved on Earth.

   It is also possible that these microorganisms that can survive in extreme environments will move towards the evolutionary path created by the civilization of the previous era in millions or hundreds of millions of years.

Depending on the long-term breastfeeding, they may grow into complex life forms such as plants, mammals, fish and invertebrates, or they may go to a completely different evolutionary path, and may even no longer appear carbon-based organisms, but appear. Silicon-based organisms that metabolize silica, or energy-bodied beings that do not have corpses.

   Of course, considering the various advantages of carbon-based and the origin and choice of carbon-based life forms, the possibility of the latter is very unlikely.

No matter whether life appears or not, no matter which path the latecomers take, the time scale will be stretched to an unimaginable level. For human beings, millions of years cover the entire process of civilization from germination to growth to prosperity, decline and demise. , and in the case of galaxies and the universe, millions of years are just a blink of an eye. "

   The subtitles ended here, and everyone still held their breaths, daring not to make a sound. Ou Yang put down his precious pen, Director Wei scratched his neat hair, Qi's uncle and nephew stared at the teacup in front of him without saying a word, Yu Qian quietly opened the gourd and raised his head to drink, Yang Xiaoqian rubbed his eyebrows with a headache. and temples.

"If it's the meteorite that caused the Chicxulub crater, oh, the asteroid that is thought to have caused the Cretaceous mass extinction 65 million years ago, then we have a solution, even if If it cannot be successfully intercepted and turned, then after it is smashed by nuclear weapons in low earth orbit, the small meteorites with scattered masses cannot penetrate the crust, and they will not cause the magma inside the earth to be ejected, nor will it cause supervolcanic eruptions. A region like the Yucatan that is rich in crude oil and hydrocarbons, but hits a low-to-medium hydrocarbon region, would not cause a mass extinction."

  With the video as a foreshadowing, Academician Zhu began to answer Yang Xiaoqian's questions.

"But if an asteroid with a diameter of 500 kilometers in the video hits the earth, we are really helpless. In fact, according to the information now translated, another earth's, er, the Royal Academy of Sciences of the Great German Empire, has already We've tried all the ideas we've had now, and they don't work."

   In other words, with the current technological level of human beings on Earth, once they encounter such a disaster, they can only wait for death.

Yang Xiaoqian rarely showed his irritability on his face. He rudely emptied the teacup, grabbed the wine gourd from Jiaoqian's hand, and poured wine into the empty glass. The smell of wine and smoke filled the conference room, Director Wei wrinkled. He frowned, hesitated again and again but remained silent.

"Oh, we humans are really too small." Academician Zhu's mood and perception are obviously more complicated than those "illiterate" in the conference room who don't know the vastness of the universe, "Maybe it is really good luck to be able to develop a civilization, wait until One day I won't be so lucky, I'm afraid..."

The pessimism and despair in the eyes of the audience are already strong enough. The elderly should not spread such negative concepts, but no one has spoken out to stop them. Watching the video for more than an hour seems to have used up all people's strength, and it is difficult to even raise their lips. rise.

   After a while, someone asked out loud, "Academician Zhu, is there a high probability of an asteroid impact of this magnitude?"

"How to say, asteroids are also planets, but any asteroid with sufficient mass and volume should be captured by a celestial body larger than it after entering the gravitational range of a star or a large planet, and either become a star's planet, or become a star's planet. satellites of the planets."

"Astronomers around the world have never discovered any asteroid with a diameter of more than 100 kilometers and an irregular orbit. Generally speaking, an asteroid impact of this scale is caused by the intersection of the orbits of many celestial bodies. We all know that in the solar system, in addition to celestial bodies orbiting stars in elliptical orbits, there are also celestial bodies orbiting in other orbits. When their orbits coincide at a certain point, the interaction of gravitational forces will break the balance and cause collisions.”

"And like the situation we saw in our video, the asteroid is like a bullet shot by a sniper, accurately avoiding the gravitational effect of other celestial bodies during its operation and flying directly to the earth, or it is more like a Calculate the gravitational effect of other celestial bodies in advance, then enter the right trajectory at the right time, at the right speed, and then go straight to the low-Earth orbit to be captured by the Earth's gravity... A coincidence like this, if it is really just a coincidence, then The probability of it happening is probably even smaller than the probability of life appearing."

   The person who asked the question let out a long sigh, as if he had saved his life, but he just took a breath when Yang Xiaoqian asked him to take that breath back.

   "No offense, Academician Zhu" Yang Xiaoqian shook his head, looked at the computer's camera, and said sincerely, "I think it is meaningless to use astrophysical and mathematical probability to discuss the possibility of an asteroid impact."

   "On another earth, four hundred years ago in the Ming Dynasty, the first disaster of unknown origin occurred, living corpses, which are what we call zombies and mutants, and awakened ones."

   "In our world, last July, zombies, mutants and awakened people also appeared."

   "In that world destroyed by asteroids, in 2000, zombies, mutants and awakened people appeared again."

"what does that mean?"
