Nuclear war, global warming, pandemics some dangerous disease … These are all potential threats that could destroy life on Earth and even the planet itself, but scientists are still decided by six other disasters that could wipe out the human race on our planet.
The massive solar storm
sun is not as smooth as it seems. It has a strong magnetic field and solar storms , which creates, in a collision with the Earth’s magnetic field, leading the appearance Aurea Borealis. The most powerful magnetic storm has been documented on Earth in 1859 is known as the Carrington event. In history, it was more similar events, but with lower intensity. More bigger and stronger solar storms could have fatal consequences for the people, not only the different communication and navigation devices.
Asteroids are dangerous, it confirms the fact that they contributed to the extinction of the dinosaurs. Solar system moves many such bodies that represent a real danger to the Earth and life on it. Scientists are developing systems that could protect us from smaller asteroids. But against the bigger we are helpless. I attack probably would not be in time destroy the planet or to cause great tsunamje, fires and other natural disasters that could destroy the human race.
The expansion of the sun
Sun will end their life for 7.72 billion years ago, scientists estimate. Then they will discard their outer atmosphere of that will be formed planetary nebula, the Sun will end up as a “white dwarf”. But the human species on Earth will not wait for that moment. Namely, that the sun aging so will get bigger, but also colder. It will create such a solar storm that will slow down the movement of the Earth, and as a result, for about 7:59 billion years, our planet will be dissolved.
Local Gamma Ray Burst
Such an explosion caused by a binary star systems or a supernova, a star that just explode. It is a very strong and powerful explosions that do not last more than a few seconds or minutes. The radiation from such an explosion could destroy our ozone layer, exposing people strong UV radiation. Astronomers have detected such a system WR 104 that could cause such an explosion. It is from 5200 to 7500 light years which is not far enough to be sure.
Supernova occurs when a star reaches the end of its life, and in our galaxy happens every 100 years. Such explosions are often the center of the Milky Way, and the earth is not in that area, this is a good sign.
The next supernova could be the star Betelgeuse, which is located in the constellation of Orion, only 460 to 650 light years. To her explosion damaged the Earth’s layer should be at least 50 light years but it seems that it does not represent a catastrophe for the people.
Some of the stars stray on their way through the Milky Way could get so close to the Sun and the Oort cloud cometary nuclei located on the border of the solar system. This could increase the chances that some of the comet headed toward Earth.
Earth is protected heliosphere, which occurs the action of the solar wind and protects us from cosmic rays, but for 20 to 50,000 years it could be less efficient, which will drastically boost climate change and make the human race to fight for survival,
