How many people - so many opinions. This famous and so true saying can be used in almost every life situation, from "the sandwich falls down oil" and ending with the causes of the apocalypse.
Yes, yes, the apocalypse, it is about him and about why he can come, we will speak in this collection.
1. Apocalypse, predicted by the Maya tribe
In the records of the Mayan tribe, there are no clear indications that the Earth will cease to exist on December 21, 2012. But a number of significant events they still managed to predict more than accurately. According to the clergy of the Mayan tribe, the flow of time is cyclical, and not linear, and according to their calendar, the end of the current cycle and the beginning of the new one is just the same as on December 21, 2012, and hence the "reset" was quite possible.
2. Collision with an asteroid
Collision with an asteroid is a subject that is pedaled almost in every third film-catastrophe, and also according to many scientists is the mysterious reason that once dinosaurs died out. It is not excluded that humanity can overtake the same fate. The chances of such a confluence of circumstances are about 1 \ 700000 - significantly higher than the set of others. But the chances to prevent a collision are also very high: with the help of modern equipment, an asteroid can be traced and destroyed before it reaches Earth.
3. Ice Age
Change in climatic conditions can gradually lead to an ice age. Of course, in the near future we have nothing to fear, but the following generations can be less lucky ...
4. Nuclear war
In fact, nuclear war is one of the most probable end-of-the-world scenarios, and also one of the most terrible. In addition to the fact that the war itself will be cruel and uncompromising, its result - nuclear winter - is a phenomenon so devastating that it is almost impossible to survive it.
5. Biotechnological disaster
At present, experiments on genetic engineering are conducted everywhere. It's scary to think what will happen in case of a fatal mistake. Unfortunately, scientists still can not state with certainty that genetically modified foodstuffs do not exert any influence, getting into the body, and also in no way interact with the human genes, provoking dangerous mutations. Do not exclude the option of "zombie apocalypse".
6. Invasion of aliens
There is a huge amount of resources here on Earth that turn our planet into a potential destination for aliens. Most likely they will need hydrogen for refueling aircraft or something else, which is rich in our planet. In any case, people can not predict the invasion. It remains only to wait ...
7. Rise of the Machines
Another potential cause of the end of the world, standing alongside the biotechnological catastrophe, is an uprising of robots. As it usually happens: there is one active copy and, guided by the thought that "he" (or "her") will suffice, it incites the brethren to illegal actions.
8. Mass insanity
This reason may seem crazy to you, but still ... it's not such an absurd end-of-the-world scenario. People hit a healthy lifestyle: proper nutrition, fitness 3 times a week - this is today "fashionable" ... But they began to forget about their morale. The number of people suffering from depression, insomnia and wanting to commit suicide has increased, even among the elderly (65 and older). Why wait further?!.
9. Black Holes
Scientists believe that about 10 million black holes exist in our galaxy alone (the Milky Way), what can we say about the rest. Like the stars, they slowly rotate and move throughout the infinite space of the cosmos. Consequently, one of these "holes" can be in orbit of the Earth and safely tighten it into non-existence. Together with us.
10. The eruption of a giant volcano
Of the approximately five hundred active volcanoes in existence in the world today, there are several so-called "super-volcanoes": three in the US (for example, Yellowstone), one on Lake Toba in Indonesia, one in Taupo, New Zealand, and Caldera called Ira in Japan. Each of these volcanoes can eject more than 1000 km3 of emissions (including magma) - which, literally, is thousands of times larger than the volume of emissions of large volcanoes in the history of mankind. The destruction in the case of the eruption of a giant volcano will be colossal. Yellowstone, for example, can throw about 2,000 million tons of sulfuric acid, which equates to the effect of "nuclear winter". As a result of such an eruption, dust and dirt will completely block the access of sunlight to Earth for several years.
