: Small celestial bodies hit
. Representative works: "Heaven and Earth Collision" and "Peerless Celestial Tribulation"
In 1998, these two disaster films with the theme of small celestial bodies hitting the earth were released one after another, causing people to think about the occurrence of such collisions. , And this has induced concerns about large-scale tsunamis and dust covering the sun and global ice. There is a conjecture that the extinction of dinosaurs can be attributed to the impact of extraterrestrial bodies such as asteroids or comets. The impact of Comet Shoemaker-Levy 9 on Jupiter in 1994 also made all mankind aware of the threat of small celestial bodies impacting planets. Simulation experiments show that if an asteroid with a diameter of about 10 kilometers hits the earth, the dust raised by the impact will cause severe winters and crop failures on a global scale, leading to the collapse of human civilization. Fortunately, according to the current astronomical observation results, the earth will not be threatened by such a huge small celestial body for the time being. The second reason for the destruction of
: global climate change
masterpieces: "The Day After Acquired", "Snow Country Train", and "Interstellar Crossing"
Since the Industrial Revolution, human activities have profoundly changed the face of the earth and even changed the climate in some regions. The melting of polar glaciers and rising sea levels caused by global warming will undoubtedly lead to the destruction of these cities, which in turn will impact the stability of human society. "The Day After Acquired" describes another consequence of the greenhouse effect, that is, global climate change has caused seasonal disturbances, and sudden strong cold currents have instantly frozen the bustling cities. The background of "Snow Country Train" is an unsuccessful attempt by mankind to alleviate the greenhouse effect. This well-intentioned disaster also shows that the global climate is a very complex system, and self-righteous changes are likely to trigger the "butterfly effect." The third reason for the destruction of
: The biochemical experiment is out of control.
masterpiece: "I am a legend" and "Twelve Monkeys"
There are many zombie-themed movies, and science fiction elements give new connotations to this ancient horror theme. This type of film imagines that a certain mysterious disease or out-of-control biochemical experiment will directly turn most humans into walking corpses; and the surviving normal people will struggle to survive in this world where modern civilization has collapsed. Through this type of film, we can feel the fragility of modern human civilization. Without the services that support modern society, such as electricity, tap water, gas, telecommunications, and the Internet, many people with weak adaptability will die quickly and miserably; while modern cities that are lost to maintenance will quickly disappear and the traces of modern civilization will become more and more. The more dangerous it is. The fourth reason for the destruction of
: the global nuclear war
masterpiece: "The Sum of Fears"
"The Sum of Fears" can hardly be regarded as a science fiction film, its background and the technology appearing in the film, almost all exist in reality. But it did a very exciting thought experiment: the nuclear standoff between the United States and the Soviet Union (Russia) and other nuclear powers could break out almost at any time and evolve into a nuclear war on a global scale. In this film, a neo-Nazi terrorist detonated an atomic bomb smuggled from Israel in Baltimore, the United States, almost causing a full-scale nuclear war between the United States and Russia. In fact, at the peak of the US-Soviet struggle for hegemony, these two nuclear powers stocked up nuclear weapons that could destroy humanity on Earth several times. Moreover, in the decades since the Soviet Union mastered intercontinental missiles until Russia took over these "nuclear heritage", there have been several accidents that could trigger a nuclear war. It was only because the operators were careful and timely to verify that they did not cause major disasters. . The fifth reason for the destruction of
: Artificial intelligence is out of control
Representative works: "Terminator" series, "Mechanical Enemy"
Nowadays, supercomputers are nothing new to beat human top players in chess games and TV quizzes. Decades before that, some people were worried about the ever-changing artificial intelligence technology, believing that artificial intelligence that is out of control might one day "rebel" and destroy mankind's rule of the earth. The "Terminator" series of movies express this concern: tireless intelligent robots with weapons have formed another "civilization" that will slaughter the humans on earth who created them. Compared with humans, the biggest advantage of artificial intelligence such as intelligent robots is that they are tireless and painful, which in some cases will become the "ultimate" they bring to humans.Fear.” Today, many top scientists are calling for restrictions on the development of artificial intelligence technology until mankind can find a better way to control them. The sixth reason for the destruction of
: the invasion of extraterrestrial civilization
masterpiece: "Independence Day" and "Frozen "The Planet" and "World War"
throughout the history of science fiction movies, it is believed that extraterrestrial intelligent life (even life in the form of energy) will attack the earth with a technological strength far beyond human beings. It can be described as a lot of work. The famous Chinese science fiction writer Liu Cixin The representative work "Three-Body" actually belongs to this category of themes. To this day, we still cannot determine the good and evil of extraterrestrial civilization, and some science fiction novels also put forward a third point of view, that is, the actions of extraterrestrial civilization It doesn’t matter good or evil, evil in the eyes of human beings is only the result of cultural conflict. What will happen to the real future of
? Let’s wait and see.
