Nerdery final possible and inevitable.
The survival of humanity and civilization is a natural instinct, thanks to which people have been around for thousands of years. However, over the last few decades the scientific community has advanced the hypothesis that any global catastrophic risks can cause significant damage to human civilization or even destroy it.
1. Era of black holes
“The era of black holes” is a hypothetical age of the Universe, during which the organized matter will remain only in the form of black holes. Black holes will slowly “evaporate” by quantum-mechanical process of Hawking radiation. By the end of this era there will be only extremely low-energy photons, electrons, positrons and neutrinos. In other words, the Ground will be to say goodbye.
2. Grey goo
A similar term called the hypothetical risk of “doomsday”. Under this scenario, the development of molecular nanotechnology, self-replicating robots get out of control, killing people and conquering the planet. Isn’t that reminiscent of “the Terminator”.
3. Gamma-ray burst
Some scientists fear that the gamma-ray burst, the most powerful type of explosion known in the Universe (today it is observed in distant galaxies), can cause mass extinction on Earth within a day. These lethal explosions can also help to explain the so-called Fermi paradox – the apparent contradiction between the high probability of the existence of alien life and the lack of evidence of its existence.
4. Climate change
Perhaps the most well-known risk worldwide during the last several decades – the risk of global warming on Earth. Due to severe climate change can be solved forever different species, including humans.
5. A coronal mass ejection
Coronal emissions – huge bubbles of gas ejected from the Sun for several hours. According to some scholars, the uncontrolled release of a coronal mass ejection may one day cause the destruction of our planet.
6. A big gap
“The great divide” is another controversial cosmological hypothesis. According to this hypothesis, matter of the Universe, from stars and galaxies to atoms and subatomic particles, gradually “explode” due to the expansion of the Universe.
7. Genetic pollution
“Genetic pollution” is a controversial term used to describe the possibility of genetically modified organisms into wild populations. This “stream of new genes” is highly undesirable according to some environmentalists, because new organisms are created through genetic engineering will interact with other life forms, reproduce them, transfer their characteristics and become dominant.
8. Natural pandemic
Another risk, which seems quite realistic according to scientists, is a natural pandemic that can be transmitted through the air and kill people for several hours, while the scientific community will not be able to find an effective treatment during this time. One has only to remember the Black death, which killed half the population of Europe in the middle ages.
9. The End Of The Universe
This theory argues that there are two possible ways of destruction of the Universe. Some say that the world will “end in fire”, while others claim that the end will come “in the ice”. Anyway, both sides agree that it will be total destruction.
Today continually heard statements about the dangers of overpopulation. Most experts predict that by 2050 it will be one of the biggest problems in the world. The human population will be so large that the limited resources of the planet, such as water and oil, not to be missed at all. This will lead to famine, drought, disease, and endless wars between countries.
11. The third world war
Albert Einstein was one of the first who described the tragic consequences of a third world war to society and the planet. He said: “I do not know what weapons will be conducted a third world war, but world war IV will be fought with sticks and stones.”
12. Nuclear Apocalypse
Nuclear Holocaust or the Apocalypse – a possible complete or nearly complete annihilation of human life with the help of a large number of nuclear weapons. In this case, the entire territory of the Earth or most of it will become uninhabitable.
13. The new world order
The new world order is more of a conspiracy theory. It suggests that some powerful group (Illuminati, Freemasons, Zionists, etc.) controls human society and will do everything possible to destroy a large part of humanity or just enslave it.
14. Alien invasion
This theory has existed since ancient times. Most people (if not all) have seen movies in which a strange looking aliens from outer space invade our planet and try to destroy all life on it. Of course, this still has not happened, and nobody thinks that this will happen in the near future.
“Transhumanism” is defined as an international cultural and intellectual movement that emerged in the last few years. Its primary goal is the total transformation of the human condition through the development and wide dissemination of technologies that will greatly enhance intellectual, physical and psychological capabilities. Despite the fact that it sounded quite “good”, according to most thinkers, transhumanism can end human life in its present form.
