Zhang Wei slept soundly, but the impact of what he said at the Nobel Prize awarding ceremony is continuing to ferment, causing heated discussions.

Future technology company, astronaut training base.

In the lounge, Wang Chen was discussing the alien issue mentioned by Zhang Wei with his colleague and friend Huang Xiaofeng.

Wang Chen has always believed in the existence of aliens. Like Zhang Wei, he even believes that human beings may be the descendants of aliens who immigrated from the stars, but they were abandoned here for unknown reasons. In order to convince Huang Xiaofeng, he used his mobile phone to log in to the network disk, and opened a document in his collection for Huang Xiaofeng to read.

Humans are latecomers on the earth. In the 4.5 billion years of the earth's history, human beings have only participated in a short moment. If the entire history of the earth is shortened to 24 hours a day, then human beings will not wait till 23 o'clock in the evening of this day. It took 58 minutes to make its debut. Human beings still know very little about the history of life on earth.

At the beginning of the 20th century, the Russian chemist Alexander Obalin and the Indian-British biochemist Haldane proposed the chemical generation theory of life. They believed that the early earth environment was suitable for the combination of simple inorganic molecules to form complex organic macromolecules , and thus lead to the eventual generation of life. In the 1950s, Stanley Miller, an American biochemist working at the University of Chicago, and Harold Urey, a famous American chemist, conducted a classic experiment, which was later called the Urey-Miller Experiment. experiment to test this hypothesis.

In the experiment, Miller and Uri filled an experimental container with a mixture of gases, including water vapor, methane, ammonia and hydrogen, to simulate the early Earth's atmosphere; and filled a certain amount of liquid water to simulate the early Earth's ocean. Electrodes are then used to discharge the atmosphere, simulating the lightning strikes that occurred frequently on early Earth. After the experiment was carried out for about a week, a large amount of dark viscous~thick compounds had appeared in the container. When analyzing the substances, the scientists found more than 20 different amino acids.

The Uri-Müller experiment, and others that followed, supported the chemical origin theory of life, which arose directly from chemistry in the early Earth environment.

However, many experts remain skeptical about this theory. The famous British astrophysicist Fred Hoyle, for example, scoffed at the idea of ​​the earliest life being produced by chemical processes, saying that it is like a tornado sweeps through a garbage dump, and then happens to assemble a Boeing 747. airliner.

The naysayers are not without reason.

Life itself arose on Earth very early, somewhat unexpectedly. Just in October 2015, scientists at the University of California, Los Angeles announced that the earliest life on earth appeared at least about 4.1 billion years ago.

This result pushes the previous record back again by about 300 million years. You must know that the earth was born about 4.54 billion years ago, and this research means that life appeared in a short time after the birth of the earth.

It took a long time for life to emerge through chemical processes, and apparently life on Earth appeared too quickly.

In 1984, American female scientist Skoll and her companions discovered a dark rock during an investigation in the Mount Allen area of ​​Antarctica. It was initially determined to be a meteorite. The first meteorite found in the area, according to convention, named it alh84001.

At that time, no one paid special attention to this rock, and no one would have thought that this rock would become the headlines of the world's major media more than 10 years later. However, in 1996, NASA scientists announced the discovery of suspected Martian microbial fossils inside alh84001, which caused huge shocks around the world.

Although the reliability of this conclusion has been generally questioned by the academic community, the possibility behind it is very representative: Could life on earth be alien?

This theory has received widespread attention since it was put forward, and people call it the germ theory. This theory holds that life on Earth came to Earth from other parts of the universe through meteorite fall and other means. Experiments have also proved that under suitable conditions, microorganisms living inside rocks may indeed survive when meteorites pass through the earth's atmosphere, and all life on earth today is the descendant of the evolution and multiplication of these alien life forms. Even though meteorites did not bring ready-made life to the earth, a large amount of organic matter has indeed been found in meteorites. For example, in the Murchison meteorite that fell to Australia in 1969, scientists have identified more than 100 amino acids.

According to this, in the strict sense, we may not be earthlings at all, but interstellar immigrants from other places in the universe.

After Huang Xiaofeng finished reading, Wang Chen put back his phone and asked with a smile, How is it? Do you think it makes sense?

Huang Xiaofeng said, This article is the work of Minke, right? It seems reasonable, but the current academic mainstream still believes that humans evolved from monkeys. And if we are really descendants of aliens, then It means that other aliens may visit the earth at any time, and these aliens must have advanced technology, if they want to enslave or even destroy us, wouldn't we have no ability to resist at all?

Wang Chen replied, Yes, this is what I am worried about. If the earth civilization really comes into contact with alien civilizations, it is likely to be a disaster. For example, Voyager 1 has now flown out of the solar system and drifted far away from the earth. The distant universe of 19 billion kilometers is deep space, if it is captured by aliens, it may attract aliens and bring us a threat.

Then, Wang Chen shook his head with a smile again, I was thinking too much. At the speed of Voyager 1, it would take 70,000 years to reach the nearest star system to the earth—Alpha Centauri. As far as aliens are concerned, they are the aliens closest to us. With our current development speed, we may become a god-level civilization in 70,000 years. If aliens really come to our door, the scene must be very exciting .”

Huang Xiaofeng was also happy, Why do I feel that Voyager 1 is a conspiracy? When it is picked up by aliens 70,000 years later, it will become bait. Aliens are fish, and humans are fishermen. !

The two chatted for a while, Wang Chen looked at the time, stood up and said, Enough rest, it's time to continue training, there are still ten months left, the company's first spaceship will be completed, when we There is a chance to go to the moon, go to Mars, and see if there are any traces left by aliens.

...

At the same time, netizens are also discussing heatedly.

Zhang Wei's speeches are always full of passion and interesting to listen to, unlike other scientists who specialize in terms that ordinary people cannot understand. And the future life he describes is always full of expectations.

Dr. Zhang is also a part-time prophet. What do you think of his two predictions?

You have to believe it. It seems that what he said has come true, and this time will definitely be no exception!

It can also be seen from Zhang Wei's first prediction that future technology companies should focus on the space field, explore space, develop space resources, and search for aliens at the same time.

Not only future technology companies, but major countries around the world have adjusted their strategies to develop space technology, and the earth has officially entered the space age.

As far as I know, our country has formulated a policy to serve the space age, and it will be promulgated soon.

According to this policy, the country will focus on the development of space technology in the future. For this reason, all infrastructure construction will be suspended or delayed. In the future, most of the resources will be given priority to the development of space technology. (It is worth mentioning that in fact, after the launch of the anti-gravity flying car, our country has already greatly reduced the construction of infrastructure such as roads, railways, airports, and ports, because anti-gravity flying cars, anti-gravity flying trucks and other anti-gravity equipment It is bound to be popularized, and these infrastructures will also face the dilemma of becoming obsolete.)

In addition, all domestic universities must establish aerospace majors and other majors related to space technology, focus on training relevant talents, and reserve human resources for the development of space. Speaking of this, I have to mention one thing. With the emergence of intelligent robots, many majors in universities and vocational schools have completely disappeared, and even many vocational schools have completely closed down, such as training excavators, training electric welding, and training foreign languages. , Train chefs, because in a few years, these jobs will be replaced by intelligent robots, even if they are trained, they will still be unemployed! The country has issued relevant policies to arrange for students to switch majors and arrange for employed persons to re-enroll in order to adapt to the coming era of intelligent robots, and many of these students have entered majors related to space technology.

It can be said that space will be the most important development direction of our country in the future, and manpower, material resources, financial resources, and policies will all serve to enter space.

The United States, Russia, Japan, India, the United Kingdom, Germany, France, South Korea and other countries are also considering similar policies, listing space technology as a top priority strategic technology, and there will be a lot of resources tilted towards space technology. According to our It is estimated that these policies will be announced within a few months. The remaining countries actually want to develop space technology, but they have no technology and no money, so they can only watch helplessly.

You may wonder why governments of various countries attach so much importance to space technology? That's because space technology determines the future of the nation. In space, there are endless wealth such as energy, rare metals, and minerals.

On the moon, there are millions of tons of helium-3, and the energy provided by it as nuclear fusion raw material is enough for our country to use for tens of thousands of years. In addition, there are more rare metals on the moon than on the earth. , We can also build cities on the moon, grow food, open factories, emigrate to the past, and relieve the pressure on the earth's population.

In addition to the moon, there are countless asteroids in the solar system. These asteroids also have a lot of wealth. For example, scientists estimate that the core of the asteroid numbered uw-158 contains 100 million tons of platinum, worth as much as 3.5 trillion GBP ($5.4 trillion). According to the current survey results of scientists, asteroids as valuable as uw-158 abound, such as: 162385 (2000bm19) asteroid worth 3.44 trillion US dollars; 4034vishnu asteroid worth 2.51 trillion US dollars; 65679 (198~9uq) Asteroid 1.77 trillion; 7753 (1988xb) asteroid 1.38 trillion; 3200phaethon asteroid 870 billion. There is also an asteroid named Germany 241. According to estimates, the value of mineral resources it contains is as high as 95.8 trillion US dollars, which is almost equivalent to the GDP of the entire world.

In addition to the endless resources and wealth in space, there is also a reason why all countries are fully developing space technology, that is, the resources on the planet are actually running out and cannot support us to continue to consume them. If we do not make changes, only Can stay on the earth for life, until death. In addition, our country took the lead in launching the plan to conquer the moon, which also awakened other countries. Otherwise, the space age should be delayed by 30 to 50 years.

Damn, are the people inside the system upstairs? They even know the strategies of countries around the world. However, I also think that the real space age has arrived. In this era, we should see the vast world outside instead of the small world. Earth.

These netizens are discussing aliens and space, and many netizens are discussing Zhang Wei's second prophecy, which is that human beings can extend their lifespan to 500 years within 50 years.

I really hope that Zhang Wei can realize this prophecy soon. Fifty years is too long, I can't wait!

I remember that Zhang Wei mentioned for the first time that he wanted human beings to live to 500 years old at the press conference of 'Future No. The life expectancy will be extended to 500 years within ten years. This shows that Zhang Wei must have made some progress, and he is confident that he will accomplish this feat within fifty years. Do you think my speculation is reasonable?

I'm sorry, the devil is in the details. I think what you said is very reasonable. Judging from Zhang Wei's consistent style, what he said can definitely be realized, and there is a great possibility to realize it in advance. I remember it very clearly. Zhang Wei said at the first press conference in his life that he has the ability to perfect the anti-gravity technology in five years, and it turned out that he only took four months to create the anti-gravity flying car. So I believe Zhang Wei We must invent life-extending drugs in a shorter time, even if we don’t live to five hundred years old, we can live to two hundred years old.”

However, even if Zhang Wei invented such a drug, it must be a sky-high price. The average person cannot afford it. Only the rich and powerful can borrow another five hundred years from the sky. We ordinary people should just wash up and sleep. .”

If there is a chance to live, who would want to die? As long as there is such a medicine, I will steal it, steal it, cheat it, and do whatever it takes to make up enough money! This is a lifespan of 500 years, and even the emperors in ancient times could not enjoy it .”

Upstairs, you think too much. The police have cooperated with the future technology company to use the artificial intelligence technology provided by Zhang Wei to establish a nationwide smart policing platform. Surveillance cameras in public places across the country have already cooperated with the police's smart police. The service platform is connected together. Any wanted criminal suspect will be identified as long as his face is captured by a surveillance camera, and the police will arrive in the shortest time. In addition, if you commit a crime somewhere, After the police receive a call to the police, the smart police platform will automatically call the surrounding surveillance cameras to analyze suspicious persons. It is said that the accuracy rate is as high as 70%. Unless you are a master criminal, don’t think about this road. In this day and age, robbery and stealing are the stupidest crimes.

That's right, I heard that the country is planning to purchase a new generation of gene sequencers from future technology companies to popularize genetic ID cards. Everyone's genes will be entered into the national gene bank. When the time comes, the hair you left at the crime scene, Insignificant things such as skin flakes, saliva, and fingerprints will help the police lock your identity, so don’t try to go astray. There is a saying that goes well, thirty years in Hedong and thirty years in Hexi, now it is In the era of great change, there are many opportunities, and we can make a fortune if we follow the right path.”

Pfft...Thirty years in Hedong and thirty years in Hexi, this sentence is inexplicably familiar, dare I ask if the upstairs is Xiao Yan? (To be continued.)
