Chapter 209

Aliens never come again, but when they will come!

Xu zhe stared into Hao Zhi's eyes and said: "In our universe, there are 200 billion stars in the Milky Way alone. Even if there is only one in ten thousand with a similar environment to the solar system, there may be 20 million civilizations developing. Even if we can reach advanced civilization, there is also one in ten thousand. There are also 2000 civilizations that have reached or surpassed the earth, and the local galaxy group of the Milky way is composed of 100 such civilizations Galaxy composition, that is, there are 20000 super civilizations near us... "

Twenty thousand threats... Hao Zhi subconsciously repeated them.

"Moreover, it's the most conservative estimate!" Xu zhe added. "If you use a more optimistic estimate, there are two million advanced civilizations in this galaxy group alone!"

Two million... Hao Zhi can't piece together this huge digital foundation in his mind. If every civilization has 6 billion people like the earth, how many people... What a crowded universe?

"However, for such a high probability event, before the arrival of the blood moon civilization, mankind has never found any trace of civilization! You know, the observation ability of human beings on earth has seen almost 12 billion light-years away. In terms of distance, it is almost close to the observable edge of the universe. Since the birth of the universe, it is only 1 More than 3 billion years! However, we have never found anything, not even a strange electromagnetic signal or a regularly flashing light! This is what modern astronomers call a strange phenomenon - the great silence of the universe! It exists but is not found! "

"Like hide and seek?"

"Yes, it's like playing hide and seek. Everyone who hides doesn't find it, but they don't want to be found!"

"What if they were found?"

"Didn't the blood moon find the earth?"

"Oh..." Hao Zhi seems to understand, "that is to say, while we are looking for aliens, aliens are also trying to find us!"

"Finding or being found is theoretically just a matter of time!" Xu zhe pointed to the sky with one hand, "Our luck is that the scientific and technological level of the blood moon civilization is only a little ahead of us. We fought to the death and finally defended the possibility of the continuation of our civilization. But I ask you, if tomorrow, another advanced civilization will invade the earth, and their weapons and technology are much higher than the blood moon, so high that we can't imagine, I'm sorry What should we do? "

"Only waiting to die..." Song Xiaojia replied helplessly.

"Yes! So we must recover as soon as possible, seize the time, revive the earth civilization against time, and make all preparations to resist foreign enemies before the invasion!" Xu zhe said decisively.

"But what is the revival of civilization?" Dian asked a key question.

"The first step in my plan is to restore the earth's climate and environment. Otherwise, mankind will die completely in less than 50 years!"

"Why? Is it because zombies eat people?"

"No, those who are not important and are infected with corpse bacteria can always be cured as long as they continue to develop drugs. Now, the more important problem of survival is in front of us! That is the destruction of the moon, which is bound to lead to the mass extinction of life on earth, including human beings!"

It's just that the moon is gone. It's only August 15 after the big deal. Hao Zhipi's mouth is curled.

Hehe, do you think the moon is just a bright spot the size of a dollar hanging in the sky every night? It's just a pictogram? The importance of the moon is far from as simple as you think!

The serious consequences of the disappearance of the moon are emerging step by step. First, it is precisely because of the traction of the lunar gravity that the earth, as we now know, lies half on the plane of the orbit and rotates obliquely. The moon disappears. Now the earth is like a falling gyro, and the axis of rotation has begun to shake, deflect, and even the future, There will be a situation lying across the ecliptic. At that time, the poles will become the equator and the equator will become the poles. The huge geological and climatic changes that will have to go through will be enough to destroy 99% of life on the earth!

Moreover, from the perspective of the overall environment, the earth's own climate disaster is just drizzle. After the moon disappears, the geomagnetism will gradually weaken due to the lack of tidal friction. Earth life will gradually be exposed to the high-speed particle flow of the solar wind, die of illness, or mutate into a shape we don't know at all. Before, our geomagnetic shielding plan just lasted Two hundred million people died in one hour! Can you imagine what would happen if the geomagnetism disappeared forever?

In addition, the moon is like a shield in front of the earth. As a meat shield, it blocks most of the large meteorites that may threaten the earth. Now, the earth has lost this natural barrier. Any meteorite with a diameter of more than 20 kilometers will bring devastating disasters. You should remember how dinosaurs became extinct!

Of course, the moon has more impact on individual creatures on the earth. Newborn turtles need to rely on the moon to find the sea. Sharks need to rely on the moon's shadow to find the fish above their heads. All creatures that rely on the moon's magnetic field to identify the direction will be lost, even including the growth of all plants and crops on the earth under the moon... The chain reaction caused by the destruction of each species in the ecological chain is not The only predictable result of such a huge change is the collapse of the biosphere and the extinction of all life on earth!

So - the blood moon people didn't attack the earth at first. It's not that they miscalculated the shooting direction, but that their revenge plan was more secret!

According to our later calculations, although the space cannon composed of their blood moon debris is powerful, it can only destroy the moon. For the earth 49 times the size of the moon, it is nothing at all, not even enough to penetrate the mantle, let alone the earth's core. Even if the explosion caused by that blow destroyed 70% of human beings on earth, It is impossible to guarantee the extinction of all people on earth.

"I made a song..." Hao Zhiyi glanced, "that is to say, destroying the moon is the best way to ensure that there are no people left on earth, better than direct attack!"

"Yes, this is the last calculation of the blood moon people! Their direct purpose remains unchanged. After the failure of the volcanic plan, destroying the moon can also cause great changes in the earth's climate and destroy mankind!"

"It's so poisonous! But the moon is gone. What does it have to do with building an empire, killing people and experimenting with living people?"

Of course it does! Xu zhe sighed, do we just accept the fate of destruction? No, obviously not! We must strive for the chance to survive instead of waiting to die. Therefore, the only way is to rebuild the moon!

"Rebuild a celestial body with manpower? Don't you have a fever?" Hao Zhi shook his head.

"Of course, with the technology and strength we have left, we can't even solve the problem of food and clothing. Of course, it's impossible. Fortunately, a series of devastating consequences brought about by the destruction of the moon won't appear immediately. The fastest expectation is that it will take about 50 years to become more and more intense until it can't be cleaned up. Therefore, we still have 50 years to resume production, revitalize civilization, and finally recover Build the moon to stabilize the earth's environment again. Then, return to the right track at the fastest speed, develop science and technology rapidly, colonize the solar system, and spread our defense tentacles over the nine planets of the whole solar system. As small as taking the nine planets within Pluto as the base, we establish an interstellar gun array to defend against foreign enemies; as large as taking the one light-year radius affected by the solar gravity as the radius, we establish an interstellar patrol Air fleet, and then develop a constant interstellar air and space team with a scale of tens of millions of ships as the basic unit. At that time, it will basically have the survival ability to defend against the invasion of foreign enemies! "

Hold the grass! Hao Zhixiang was shocked as foolishly as listening to the heavenly book. On the spot, the sentence sounded again in his heart: "maybe no one has ever really seen what is thinking through Xu zhe..."

"This will be a 200 year plan for the revival of earth civilization. Maybe you and I will not live to see it come true. However, that is the foundation we have laid for future generations. Earth civilization will survive and maintain on this foundation..."

Xu Zhe's eyes lit up and looked forward to the magnificent future in his heart
