The world could end because of solar flares, cosmic collisions, or volcanic eruption. An asteroid could destroy life on Earth The Guardian Us scientists have described the most likely according to them doomsday. According to the researchers, mankind is threatened by solar activity, an asteroid impact or a SUPERVOLCANO eruption, reported in the journal Science.
The first scenario assumes that humanity will suffer due to excessive solar activity. The earth can threaten the stream of high-energy particles, which are caused by coronal mass ejections of plasma. These phenomena are associated with solar flares. A similar spike occurred in 1989, led to the fact that Quebec remained without electricity. In 1859, the emission was 10 times more powerful and led to multiple fires and stun operators of the Telegraph, and the Northern lights could be seen over Cuba.
Now, researchers fear that such emissions can weeks, months and maybe even years to de-energize entire continents. Large-scale power outages can have disastrous consequences for countries that depend on development of networks.
The second scenario associated with the fall of an asteroid can lead to the physical destruction of mankind. According to researchers, the only way to avoid this is to join forces in the fight against a potential threat. Scientists argue that the destruction of humanity is enough of an asteroid with a diameter of about a kilometer. For comparison, the dinosaurs destroyed an asteroid with a diameter of 10 kilometers. The fall of an asteroid will raise the atmosphere of clouds of dust, which will close the sunlight for months, leading to the onset on the planet “a long winter” that threatens starvation and disease. In addition, together with the asteroid will fall to Earth also a huge amount of space debris.
The third threat – the eruption of the volcano. The researchers argue that these eruptions occur on Earth roughly every 100 thousand years. For example, the eruption of the volcano Toba in Indonesia 75 thousand years ago put the ancestors of modern man to the brink of extinction. A similar event now would cause the continents covered meter layer of ash, killing crops, destroying buildings and polluting the water.
Previously, scientists have said that potentially dangerous for the Earth asteroids are invisible to ground-based telescopes. To such conclusions researchers came after analyzing the data of the detections of near-earth objects to several observatories.
