Multiple scientists: Human civilization is locked on the earth and will be extinct in 5100 years! 95% accuracy
According to the biological history of the earth, no creature can survive on the earth forever. But some people say that this law only applies to those species without civilization. Human beings are the only civilized intelligent creatures on earth and can jump out of this cycle. Is this really true after human extinction? In the 1980s, the United States conducted a big experiment to artificially create an ecological circle in an attempt to replicate a "small earth". However, the results of the experiment directly silenced the entire scientific community. So, what happened back then. Will scientists say, "We're locked on Earth!" Can humans really leave the Earth
Failed Biosphere Experiment
Can humans really Can not leave the earth, this experiment can tell us the answer, it is the sensational Biosphere 2. The entire Biosphere 2 cost 150 million US dollars to build, 80,000 steel bars and 6,000 pieces of glass, covering an area of 13,000 square meters, located in the Arizona desert. Scientists have created a miniature version of the earth's ecosystem in it, simulating various natural environments, such as deserts, grasslands, rainforests and oceans. Eight experimenters entered this artificial biosphere and carried out a 2-year experiment, but the experiment began to have problems. Biosphere 2 The oxygen content in Biosphere 2 dropped extremely after humans entered, and it was once below a safe concentration. As a last resort, the outside world can only open the oxygen supply system to provide oxygen for the experimenters inside. The experiment has already failed halfway from here. Later, the environment in Biosphere 2 continued to deteriorate, and more than half of the animals and plants died. There were also various contradictions among the eight experimenters. The two-year experiment had to be stopped at the 21st month, and the Biosphere 2 experiment ended in failure. This experiment shocked many scientists who wanted to go to the moon to establish a base at that time, because the aerospace achievements in the 1970s made people think that leaving the earth does not seem to be difficult. After what happened inside Biosphere 2, many scientists pessimistically believed that we were trapped on Earth. The oil war broke out in the 1970s and 1980s. The energy war made people realize that we seem to have entered a stage where we cannot leave fossil energy. Once there is no energy, human civilization will go backwards. Everyone knows that these fossil energy sources are limited and will be used up one day. More importantly, the environment of the earth is deteriorating. Although some of the deterioration is caused by human beings, it is undeniable that human beings also face a challenge, which is the inescapable mass extinction. Victims of the last extinction5100 years later
There have been 5 large-scale mass extinctions in the history of the earth, and the worst one almost killed the creature in half evolution. Fortunately, the last mass extinction was about 66 million years away; unfortunately, it was 66 million years ago. If calculated according to the periodicity, the mass extinction of the earth will occur every 5000 to 100 million years, and 66 million years is exactly in this interval. That is to say, a mass extinction is possible every day in the future, and even if a mass extinction occurs tomorrow, it is in line with this law. What mankind is facing is the sixth mass extinction in biological history, and many people believe that the sixth mass extinction will begin with global warming. Remains of extinct animals Looking at the five mass extinctions of the earth, the first Ordovician mass extinction and the second Devonian mass extinction were global cooling, and the third Permian mass extinction was due to the earth's own volcanic activity , the 4th mass extinction is a mystery, and the 5th mass extinction is a meteorite hitting the earth. None of these mass extinctions has been caused by global warming, so many people think that humans will be defeated by heat. With the increasing number of human beings, people and animals raised by them will occupy most of the earth's organisms, not only human industry, but also the life activities of organisms themselves will release carbon dioxide. At the same time, the number of producers will decline, and forests will be less and less covered simply because space is made for humans. The result of global warming is that carbon dioxide concentrations have reached a record high and global temperatures have reached a limit. At that time, there will be no glaciers at the poles of the earth, and the land area of the earth will be reduced by about 20% compared with the present. Diving into the sea, people will see one Atlantis after another, because many cities are submerged in water. . Human beings face a serious shortage of living space, and the roof of the world will become the most ideal place to live and be safe enough. How long will it take for the world after the glaciers melt? Scientists say that there are still 5,100 years. This time is not made by scientists, but calculated according to the Copernicus principle. The scientist who calculated this was Richard Gott, an astrophysicist at Princeton University who calculated a 95% chance of human extinction. Of course, there are other scientists who believe that the extinction of humans may have little to do with global warming, but started from within humans. Submerged cityRat's Prophecy
Before the Biosphere 2 experiment, humans had done a series of mouse experiments, among which the most famous and shocking was the Cosmic Experiment No. 25, also known as "Rat Utopia". Ecologist Dr. John Calhoun has built a rat's castle, a limited space where humans will provide endless food and water. It can be said that the mice in this utopia don't need to worry about other things, they just need to live and reproduce with peace of mind. According to Calhoun's prediction, the mice in this space will experience an exponential explosion, then tend to a stable value, and finally remain in a certain range. The first half of the rat utopia experiment went according to his expectations, but in the second half, everything got out of control. After the mice in the experimental area reached a certain limit, they began to behave abnormally, and they no longer reproduced. Even in the later stage, the number of mice is very small, and there is enough space, but the mice just don't give birth. When the last mouse dies, the 25th universe experiment ends, and all the mice in this utopia become extinct. The experiment was done in the 1970s, and the world was still in a big wave of fertility, but scientists had already discovered the clues. In the end, all the mice are wiped out, that is, the living space of the creature is certain. After the number reaches the maximum value, even if there is no need to worry about food and clothing, the desire for reproduction of the creature will decline, and this decline is irreversible. Today, Universe 25 is playing out in human society, and the fertility rate of many countries has turned red. It seems that we are gradually moving towards the end of that utopia. So how do humans need to save themselves? Are we really watching our demise in 5100 years? Population ExplosionHumanity's Self-Saving
Whether it is the sixth mass extinction or the population explosion, there is a hurdle for human beings to overcome, and that is the earth. As long as human beings live on the earth, they will always encounter earth's activities, such as earthquakes, volcanoes, tsunamis, and even an asteroid or comet impact. The space on the earth is limited, and human beings living on it will be subject to various restrictions. It seems that there is only one way for human beings to save themselves, and that is to escape from the earth and migrate to interstellar space. Space Immigrants However, Richard Gott, the scientist who counted the Copernicus principle, mentioned that there is not much time left for human space immigrants! Human civilization is almost locked on the earth. Biosphere 2 has shown that human beings are inseparable from the earth's environment, and we can't even build a similar ecology. Human beings have only set foot on the moon at present. The moon is strictly speaking the gravitational range of the earth, and we have not completely left the earth. From this point of view, the sentence that human civilization is locked on the earth is indeed correct at present, but will human beings be bound forever? Humans can never be separated from the earth According to the current development speed of human beings, in 100 to 200 years, human beings may reach the primary civilization, and in 1000 to 2000 years, human beings will reach the second civilization. Humans of the second-level civilization can directly use the energy of the sun and can travel freely in the solar system. After 5100 years, human beings can leave the earth. If there is a serious disaster on the earth, we can escape temporarily. The future of the human spaceship of the second-level civilization is not so optimistic, but it will not be very pessimistic.- Last：Handheld mini iron, smaller than a palm, lighter than a mobile phone, ironing all folds in 1 minute
