Is it true that meteorites have pores? How to identify the authenticity of meteorites

If there is no official explanation of this situation, no one knows whether it is true or not, and it will be known when it can be declassified after a few years.

As extraterrestrial objects, meteorites are the key to our exploration and understanding of the universe, and have extremely important scientific research value. In recent years, with the rise of meteorite collection, more and more people have joined the ranks of meteorite search and collection. However, due to the fact that meteorites have been given other values at home and abroad, the meteorites have risen year after year, attracting many people to spend huge energy and financial resources to search for and collect meteorites, often ending up with both people and money.

The energy contained in meteorites includes free quanta in space, bioenergy, free electrons in space, dark matter, etc.

The intensity of its energy is related to the time of existence in space, the speed of flight before entering the orbit of the planet, the direct irradiation time of the star, and the attachment or non-attachment of space creatures.

When a meteorite collides with a landed planet, it will produce huge internal energy and pressure, and the energy generated is very large, which can directly compare with the production capacity of a nuclear power plant. This is evident from the fact that the crater will have melted soil after the meteorite falls.

In addition, meteorites often have some inexplicable energies, which cannot be answered by energy science for the time being.

And if you want the meteorite to have the energy to destroy the world in the movie, then the meteorite must be at least half the size of the moon, and the surface material of the meteorite must at least be able to preserve and seal energy, and then it is possible for the meteorite to fly tens of thousands of light-years in space. An example of this is the meteorite that caused devastating damage to the Earth hundreds of millions of years ago and simultaneously exterminated the dinosaurs (this is based on the hypothesis that the extinction of the dinosaurs was caused by a space meteorite). ）。

The holes on the meteorite, not called pores, are called gas melt holes, which are produced by meteorites entering the earth at high speed from outer space and burning to produce high temperatures, and sometimes the iron ore in the boiler is burned, which will also produce this situation.

Now the fake meteorites also have pores.

The method of identifying the authenticity of meteorites is as follows:

1. Observe the surface method. First of all, meteorites are generally irregular in shape, and secondly, meteorites pass through the atmosphere during the landing process and friction produces high temperatures, so the surface of the meteorite has a layer of black molten shell formed by burning and the gas marks left by the friction of the air flow, and it also has a flow pattern or streamline structure.

2. Magnet is an experimental method. Meteorites are basically divided into three categories, namely stone meteorites, stone iron clouds, and iron meteorites. Among them, the magnetism of stone meteorites will be relatively small, and it is not easy to be attracted to magnets. However, the iron content in stone iron meteorites and iron meteorites is relatively large, and the magnetism is relatively strong.

3. Observe the chondrite method. On the fresh section of chondrites, fine chondrites and the matrix between chondrites can be observed with a magnifying glass, and fe-Ni metal and meteorite iron can be seen. Iron meteorites that corrode the polished surface of iron meteorites with an alcohol solution containing 2% concentrated nitric acid can show the Vickers Titan structure.

The structure of a meteorite is dense and it is not possible to have structures such as foamy, porous, or slag structures.

4. Ingredient detection method. Meteorites generally have a greater specific gravity than Earth's rocks due to their fe-Ni metal content (generally, meteorites have a specific gravity of at least.

Introduction of meteorites

Meteorite, also known as "meteorite", is an unburned stone, iron, or a mixture of stone-iron material that is scattered on the surface of the Earth or other planets by cosmic meteors or dust fragments that have left their original orbits outside the Earth.

On December 23, 2020, some netizens broke the news that a suspected meteorite fell in Yushu, Qinghai. **, a bright fireball crossed the sky, like day. In this regard, the reporter contacted Nangqian County**, and the staff said that they had only heard about it.

Summary. Dear, I'm glad to answer for you, and find out for you how the meteorite is true or false The answer is as follows: Identification of meteorite methods:

1. Appearance, the appearance of the meteorite has air marks of different sizes, if there is none, it may be fake; 2. Specific gravity, the specific gravity of meteorites is larger, there is a sense of weight in the hand, and the hand of the fake stone is light; 3. Magnetism, meteorites have a certain degree of magnetism, which can attract magnets; 4. Smell, meteorites have a special taste, which ordinary stones do not have. In terms of appearance, the surface of natural meteorites will form many air marks of different sizes, and there are also many raised parts, which are distributed in irregular shapes; Whereas, the surface of the fake meteorite has almost no air marks, and the raised parts are flaky. In terms of specific gravity, the density of the meteorite is about the same, and there is a small amount of metal substances inside, and the specific gravity is large. The density of the fake meteorite is small, and the feel will be much lighter.

Dear, I'm glad to answer for you, and find out how the meteorite is true or false The answer is as follows: Identification method of meteorite: 1. Appearance, the appearance of the meteorite has air marks of different sizes, and if there is no one, it may be fake; 2. Specific gravity, the specific gravity of meteorites is larger, there is a sense of weight in the hand, and the hand of the fake stone is light; 3. Magnetism, meteorites have a certain degree of filial piety magnetism, which can attract magnets; 4. Smell, meteorites have a special taste, which ordinary stones do not.

In terms of appearance, the surface of natural meteorites will form many air marks of different sizes, and there are also many raised parts of spring, which are distributed in irregular shapes; Whereas, the surface of the fake meteorite has almost no air marks, and the raised parts are flaky. In terms of specific gravity, the density of the meteorite is about the same, and there is a small amount of metal substances inside, and the specific gravity is large. The density of the fake meteorite is small, and the feel will be much lighter.

Magnetism, the meteorite contains a small amount of metallic substances, Tong Zheng is mainly based on iron, which has a certain magnetism and can easily absorb magnets; However, there is no metallic substance in the inside of the fake meteorite, and there is no magnetism in Shengchang, so it cannot attract magnets. Smell, by smelling the smell to identify, generally no matter how long the meteorite has fallen, when it encounters moisture in the air, it is easy to produce a special burnt smell, like a burnt smell, and ordinary stones will not appear this smell. I hope mine can help you, please give me a thumbs up, if you have any other questions, you can also continue to ask me questions, I wish you a happy life and all the best!

The results have been queried for you: Hello, to distinguish the authenticity of the meteorite, you can judge from the following aspects:1

Appearance: Meteorites usually have a special appearance, such as molten appearance, bubbles, metal particles, etc., if the appearance of the meteorite is different from a normal meteorite, then there is a can be a Song of God can be fake. 3.

Weight: Meteorites are usually heavier than stones of the same volume, and if the weight of the meteorite is the same as that of stones of the same volume, then it is possible that it is fake. 4.

Chemical composition: Meteorites usually have special chemical compositions, such as containing elements such as iron and nickel, and if the chemical composition of the meteorite is different from that of a normal meteorite, then it is likely to be fake. 5.

Verification: The most reliable method is to send the meteorite to a specialized laboratory for analysis and identification to determine its authenticity.

Summary. 1. Look at the molten shell.

How to identify meteorites.

Meteorites can be identified by looking at the molten crust, which produces high temperatures as it passes through the atmosphere, and the high temperature causes the surface of the fortune to melt and form a black molten crust, which is about 1 mm thick, which is one of the important characteristics of staunch meteorites.

2. Look at the air mark.

How to identify meteorites.

In addition, meteorites can also be identified by looking at air marks, which interact with the air currents during the fall, and the surface of the meteorite will also leave many air marks, which are very similar in shape to the fingerprints pressed by the finger.

3. Magnetic measurement.

How to identify meteorites.

Meteorites can also be identified by testing magnetism, meteorites are mainly divided into three categories: stony meteorites, stony-iron meteorites and iron meteorites, among which stony meteorites have low iron content and are not easily attracted to magnets. Whereas, stony-iron meteorites and iron meteorites have a high iron content and are easily attracted to magnets.

How to tell if a meteorite is real or fake.

There are three main ways to identify meteorites: 1. Looking at the molten crust, there will be a layer of black molten crust with a thickness of about 1 mm on the surface of the true meteorite; 2. There will be many air marks on the surface of the meteorite similar to finger prints, which are formed by the interaction between the meteorite and the atmospheric current; 3. Magnetic measurement, stony meteorites have low iron content and weak magnetism, while stony-iron meteorites and iron meteorites have strong magnetism.

I gave this from a friend, saying that it was a meteorite spice.

It does have a scent too.

But there is some red liquid on it.

It can be difficult to tell.

It's been cut.

Can't look at appearances.

But it can absorb magnets.

Mmmm, that's harder.

This is one of the properties of meteorites.

Summary. Looking at the molten crust, the surface of the true meteorite will have a black molten crust with a thickness of about 1 mm.

Looking at the molten crust, the surface of the true meteorite will have a black molten crust with a thickness of about 1 mm.

True meteorites have many air marks on the surface that resemble fingerprints, which are formed by the interaction between meteorites and atmospheric currents.

Measuring magnetism, stony meteorites have low iron content and weak magnetism, while stony-iron meteorites and iron meteorites have strong magnetism.

Chondrites: Most meteorites are chondrites (90% of the total), and these meteorites contain a large number of millimeter-sized silicate spheres called chondrites. Round chondrites can be seen on the fresh fracture surface of chondrites.

Can I send you a ** to show you?

OK. Pro-3 is honored to serve you and hope mine can help you.

Pro-3 If there are no other questions, please click on the upper right corner to end the consultation, give a like, thank you! Finally, I wish you all the best and a happy life.

To determine the authenticity of a meteorite, you can look at the molten crust, the meteorite will produce high temperatures during the passage through the atmosphere, and the surface will melt into a liquid due to the high temperature, and then cool to form a thin black shell with a thickness of about 1 mm. In addition, meteorites have a larger specific gravity of color than ordinary rocks, so meteorites of the same volume weigh more than ordinary rocks.

1. Look at the molten shell.

To identify the authenticity of a meteorite, you can look at the molten shell, which refers to a thin black shell with a thickness of about 1 mm on the surface of the meteorite. The molten crust is formed by the high temperature generated by the meteorite passing through the atmosphere, which causes the surface to melt into liquid, and then cools down due to the blockage of the dense atmosphere at the bottom.

2. Look at the air mark.

In addition, the authenticity of the meteorite can also be identified by looking at the air mark, the melt shell of the meteorite during the cooling process, the traces of air flow blowing on the surface of the meteorite are also preserved, this trace is called "air mark", the shape of the finger print left by finger pressing.

3. Weigh the weight.

Meteorites can also be identified by weighing, most of the real meteorites contain certain iron, nickel and other metal elements, its specific gravity is much larger than that of ordinary rocks, so the weight of the former will be greater compared with meteorites and rocks of the same volume.
