There was a loud noise over India and an unknown piece of metal fell. What is that?

The reason why netizens are curious about India is mainly because many things in India are funny and can make people laugh to death. Previously, a loud noise occurred in a shipyard in India, which led to a once-in-a-century "biogas explosion in a cesspit, and more than 200 tons of feces fell on an aircraft carrier", which became a global joke. However, this big fight in India is not funny.

Because the loud noise in India and the unknown metal falling from the sky are meteorites, there is nothing to make a fuss about. If there is anything interesting about this incident, it is this meteorite, a rare iron meteorite. Most of the meteorites that fall on the earth are stone meteorites. The attendance rate of iron meteorites on the earth does not exceed 6%.

1.0? There was a loud noise in the sky, and meteorites fell from the sky. This happened in the town of Sancho, Rajasthan. On the morning of the incident, a loud noise broke the tranquility of Sancho town, and some Indians who were still sleeping were awakened and panicked, thinking that something important had happened. However, these awakened people soon calmed down. Because after the loud noise, everything is calm again.

However, some people who got up early to go out in Sancho saw an unknown object falling from the sky, quickly streaking across the sky and falling to the ground. It is called an unknown object because it falls so fast that people can't see what it is at all. However, the true face of this unknown object soon appeared in front of the public. The reason is that someone is near the landing point.

At the falling point, an unknown object smashed a hole more than 30 centimeters deep. Unknown objects lie quietly inside. It has a strange shape and golden luster. Although people found this unknown object, they were afraid to touch it at all. The reason is that the temperature of this object is extremely high and hot air is emitted around it. When people are most afraid, they are not sure whether this object will explode.

After the incident, the staff of the local government in India arrived late, but quickly blocked the falling point. After the unidentified object was fully cooled, the local government personnel in India took it away. In the end, Indian government personnel sent this unknown object to relevant scientific research units in India.

2.0? If India gets a treasure, in fact, a piece of scrap iron is an Indian scientific research unit. After receiving this unknown object, it was very excited and regarded it as a treasure. If this unknown object from the sky makes any major discovery, they will be famous and successful. Scientists in India quickly studied and analyzed this unknown object. However, these scientists were soon disappointed.

The reason why these scientists are disappointed is that this unknown object is only a metal meteorite from space. Some elements or substances in meteorites are found on the earth, and there is no new release at all. Through analysis, it can be known that this metal meteorite is mainly composed of iron, accounting for 85.9%; Nickel is the second, accounting for10.2%; As for other elements, the proportion is very low.

Therefore, this metallic meteorite can be called iron meteorite or nickel-iron meteorite. Iron meteorites are relatively rare on earth. However, because iron meteorites are hard and resistant to high temperatures, they are very large when they fall to the ground. Now known iron meteorites weigh 60 tons. This piece in India is only 2.8 kilograms, which is very small. I don't know. It's just a piece of junk.

As for stone meteorites, because of their low hardness, they generally do not fall to the ground. At present, the heaviest meteorite in the world, weighing less than 1.8 tons, crashed in an unprecedented meteorite shower in 1976 in Jilin province. When falling, it hit the ground to form a pit with a depth of 6.5 meters and a diameter of 2 meters, and there was a mushroom cloud of dust and smoke, which was very spectacular.

3.0? Meteorite falling from the sky is never a good thing, but it may be a good thing for researchers. Because if you are not careful, there will be a new release. However, for ordinary people, it is not a good thing. In the Indian incident, people around the crash site were grateful-fortunately, the meteorite didn't hit themselves or their homes.

Meteorite falling to the earth is more of a threat to the whole world, and events that endanger life and property will occur if the color is not good. If it is serious, it may even have the effect of destroying Conan. One of the most far-reaching meteorite falls was the meteorite impact that wiped out dinosaurs 65 million years ago. This event led to the extinction of about three-quarters of animal species on the earth, including dinosaurs.

The latest meteorite fall and group injury occurred on 20 13. At that time, an asteroid with a diameter of about 20 meters entered the atmosphere and exploded violently over Chelyabinsk, Russia. Shock waves and debris from the explosion damaged more than 7,000 buildings and injured more than 65,438+0,600 people.

Unfortunately, with our current level of science and technology, there is no effective way to deal with the fall of meteorites. The best way is to expect it to burn completely in the atmosphere. At present, about 2 100 asteroids pose a potential threat to the earth and may become meteorites. I hope these asteroids will not come near and enter our earth in the end.
