The picture shows the meteorite falling
Last year, a 10-ton meteorite fell to China, and all countries congratulated and wanted it after hearing about it, and claimed that this was a great gift from the universe! This can't help but make people wonder, what kind of gift did the universe send? For the meteorite fall, it has long been regarded as a disaster by the Chinese people, after all, the ancient people are more superstitious, thinking that the meteorite falling from the sky is punishing humans, and if the meteorite falls into the residential area, it may also lead to serious casualties, such as the Russian meteorite fall caused many residents to be injured, so why do countries still express their desire?
The picture shows a meteorite
Meteorites are plainly asteroids in space, they are easily attracted by the earth under the action of gravity, causing these asteroids to continue to approach the earth, once they enter the atmosphere, due to extremely high speed, they will have a violent friction with the atmosphere, resulting in a lot of light and heat, if it is night, then you can see the meteor phenomenon, and during the day, this phenomenon is often not too concerned, so even if there are thousands or even tens of thousands of meteorites on the earth every year, The chances of people being able to witness meteorites are still very slim.
The meteorite that landed in Qinghai this time is not ordinary, because its volume is very large, according to calculations, the light weight of the meteorite that landed at that time was about 10 tons, and the diameter was more than 1 meter, when the meteorite slid down, the light produced even illuminated the night, this abnormal phenomenon, but also caused the local people to pay great attention to, and the Qinghai Provincial Earthquake Bureau also explored the meteorite landing site for the first time, fortunately, the meteorite did not hit the ground with a vertical attitude, Instead, it cuts into the atmosphere at a certain angle, similar to the return of a manned spacecraft to the earth, so the impact on the earth is not large, and it does not fall into the residential area, avoiding casualties, and this falling posture also allows the meteorite to be preserved intact.
In the impression of many people, meteorites are just ordinary stones, nothing more than it comes from space, why can it be so highly sought after? In fact, meteorites have great scientific research value, the current human space engineering, but also need to go to the moon and Mars to collect soil rock samples, this process is expensive, in the face of the active delivery of meteorites, countries will naturally fully study, because compared with the stones on the earth, meteorites are likely to contain a lot of undiscovered material, so it is of great scientific research value.
In order to find meteorites, now also specially born a profession, that is, meteorite hunters, to know that things are rare and expensive, and meteorites in their eyes, is simply more precious than gold, in the face of rare meteorites, a gram can sell thousands of yuan or even tens of thousands of yuan of sky-high prices, but also really more expensive than the unit price of gold, although the process of finding meteorites is difficult, and often accompanied by danger, but many meteorite hunters are happy to do so, of course, in China, if meteorite resources are found, it is best to report to the local relevant departments at the first time, It is absolutely impossible to take the meteorites privately, because some meteorites are often more dangerous and may contain radioactive material.
China is vast, and in ancient times there are a large number of records about meteorite falls, so this time the meteorite fell to Qinghai, there is no need to be overly nervous, although the meteorite event did not cause casualties, but still need to pay attention, such as strengthening the surveillance of space, for the general smaller size of meteorites, even if attracted by the earth's gravity will not fall to the surface of the earth, has long been burned out, and for larger meteorites, it must be issued before the fall of the alarm, so that the residents of the fall area evacuate and evacuate.
