In a series of endless wars and an arms race, people often forget about the threat that exists in space and can destroy any planet in the universe. Asteroids, comets, black holes, the convergence of galaxies and the destruction of near-planetary stars are also dangerous for the Earth.
Meteorites and comets continually fall to Earth, causing varying degrees of damage. But in the modern history of our civilization there have not been such large cosmic bodies that could destroy our civilization. But this does not mean at all that we will always be so lucky, luck is not infinite and if we just do nothing, then we can disappear in a few minutes.
Scientists who study the planets of our solar system have repeatedly stated about a large number of objects that continually bombard neighboring planets, and according to one version, the atmosphere and civilization of creatures on Mars could be destroyed by the bombardment of cosmic bodies. There is no fantasy in this and I am talking about the data that is in the public domain.
Thanks to Jupiter, most of the asteroids and other cosmic bodies do not fall on Earth, he is our guardian angel, but there are other objects in space that can bypass Jupiter's gravity and collide with our planet. Several asteroids and comets are known that in the future may collide with the Earth and at the moment our technologies do not allow us to escape from the threat from space.
The attack of asteroids, meteorites and comets on the Earth is real and it cannot be compared with the topic of cataclysms that occur on our planet. Moreover, the fall of cosmic bodies can serve as the beginning of the eruption of many volcanoes, earthquakes and waves, the height of which will reach kilometers and sweep away entire countries on their way … I really hope that in the near future a technology will appear that can protect us from such a threat.
