Why do meteorites contain information about the early solar system yet earth does not

See the explanation below.

Explanation:

That the milky way was generated by the explosion of a supernova (giant star in its last stage of life), when the content of this type of stars is based on all the existing materials as possible in the periodic table, in the moment of the explosion, a large amount of energy is released, some of these materials in the blast are left to drift, and the effect of the gravity are joining with each other, forming planets, the material that failed to form planets is orbiting freely low the attraction of the gravitational force of a new rising star, these asteroids have information about the life span of each of them, using a carbon 14 test, scientists can determine what period of formation the galaxy has.

Meteorites are solid that contain a lot of carbon, so tests on them can determine important information from the Galaxy

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
