Ten devastating disasters

First, particle experiments can devour the earth.

Particle experimental scientists use particle accelerators to make particles reach the speed of light, and then collide with each other to study the energy law of the microscopic world. Because the substance being studied is so small, human beings may never worry about what threat particles will pose to human beings. However, some serious scientific reports recently pointed out that the particle accelerator experiment or relativistic heavy ion collision experiment in Long Island, USA may produce a miniature black hole, which will slowly devour everything on the earth, including the earth.

Second, robots take over the world.

It is often reported that the speed of computers has reached hundreds of millions of times per second. Some scientific reports even believe that by 20 30, computers or robots will have the same storage capacity and processing speed as the human brain, and even completely replace human thinking. Scientists even predict that even robots in an unconscious state can pose a threat to human beings.

Third, nano-robots.

Scientists hope to make smaller and faster computer chips in a short time through the research of nanotechnology, while the long-term goal is to make micro-robots or nano-robots. They can be injected into the human body, destroying cancer cells and repairing damaged human tissues. Similarly, nano-robots can also produce useful scientific raw materials by processing various chemicals. However, according to a scientific report, nano-robots can copy themselves and all the structures they pass through to themselves, and human beings can't stop this process.

Fourth, the harm of chemical and biological weapons is not far from human beings.

In the 1960s, with the invention of antibiotics and antiviral pathogens, human beings confidently believed that we had conquered all kinds of infectious diseases forever, and all viruses could be killed by antibiotics. Unfortunately, more viruses began to change their genes to resist the effects of antibiotics. So far, the number of viruses that confuse medical scientists has increased instead of decreased.

Genetic engineering goes further. Humans have been able to change organisms by repairing DNA and use high technology to change the genetic genes of some animals or plants. Artificial chromosomes will soon be used in medicine and agricultural science. However, these well-intentioned genetic technologies may also bring unexpected disasters. Humans may think that they are manipulating a friendly biological gene, but they may destroy crops, animals and even humans in some unexpected way.

Biological and chemical weapons virus is one of the biggest threats facing mankind. It used to be difficult to make it, but now some information about making biochemical viruses on the Internet makes it very easy.

Verb (abbreviation for verb) super volcanic eruption

There have been at least six devastating volcanic eruptions on earth. Compared with these super volcanic eruptions, Mount Etna in Italy is just a pediatrician. Bill McGonagall, a professor of geophysics at University College London, believes in his book Towards the End of the World that it is only a matter of time before the next super volcano erupts.

The earthquake triggered the world economic crisis.

Humans can't predict whether the Tokyo earthquake like 1923 will happen again. In the epicenter, 200,000 people died and the economic loss reached 50 billion US dollars. Scientists estimate that if mankind suffers another Tokyo earthquake like 1923, the world stock market will dive freely and the European and American economies will collapse completely.

A big earthquake can even change the speed of the earth.

Seven, the probability of an asteroid hitting the earth is greater than winning the lottery.

In the past history of the earth, it has been hit by asteroids or comets from outer space many times, but these whispers can't do great harm to the earth because of their small size. However, scientists believe that an asteroid with a diameter exceeding 150 feet will hit the earth, which will be a disaster for mankind. If such a big asteroid hits London, it will destroy the whole of Europe. Through calculation, scientists believe that an asteroid with a diameter of 1 km will hit the earth every 65438+ million years, and such an extraterrestrial body will cause a global ecological disaster. And an extraterrestrial object with a diameter of 1 0 km will level the earth and make the earth reproduce the disaster of dinosaur extinction 65 million years ago. According to the research of Professor Duken Steele in university of salford, England, there are about 1, 500 asteroids with a diameter of 1km that have passed or are passing through the Earth's orbit.

Eight, the greenhouse effect of the hot earth is becoming more and more obvious.

In the past century, the temperature of the earth rose by 0.6 degrees Celsius, which directly led to the doubling of various natural disasters such as storms, floods and droughts on the earth. According to statistics, the number of natural disasters on the earth in 2000 was twice that of 199 6. Scientists predict that these disasters will increase sixfold in 2 1 century. The latest scientific research results prove that the Arctic Ocean ice is melting in large quantities this summer, which will accelerate global warming and make mankind "gradually die" in the heat wave of greenhouse effect in the future.

Nine. War and nuclear weapons

Since the invention of nuclear weapons, under the umbrella of nuclear intimidation, human wars have not decreased, but seem to have increased. Since 1950, there have been 20 dehumanized massacres on the earth, with the death toll exceeding1100,000. In fact, with the end of the cold war between the United States and the Soviet Union, the nuclear threat facing mankind has become more serious. According to statistics, there are currently more than 365,438+0,000 nuclear weapons in the world. As long as one thousandth of it is abused, it will lead to the early demise of mankind. Terrible nuclear war

Force majeure

In addition to the above nine threats that human beings may face, scientists also attribute the last threat to the force majeure of nature. There are many unsolved mysteries in the universe, and each mysterious force is enough to have a vital impact on the future destiny of mankind. Some scientists believe that even a supernova explosion millions of light-years away in the universe may affect the fate of the earth in space.
