Why can meteors make wishes?

Legend has it that meteors represent human destiny, and falling meteors are actually tears shed by angels. If you can catch the moment when the meteor crosses the sky and make a good wish, then God will help you realize it.

Observing meteors is of great significance for studying the structure and physical properties of the upper atmosphere, and also has applications in the field of communication. When a meteor passes through the air, it will emit a lot of light and heat, which will ionize the surrounding gas and spread rapidly, forming a columnar ionization cloud centered on the trajectory of the meteor. This ionization cloud has the property of reflecting radio waves. This is the so-called "meteor trail".

Long-distance communication using meteor trails to reflect radio waves is called meteor trails communication. Meteor trail communication is a relatively hidden and reliable long-distance and small-capacity communication means, which is mainly used for emergency communication.

The origin of meteors

In the solar system, besides the sun, eight planets and their satellites, asteroids and comets, there are a lot of dust particles and small solid blocks in interstellar space. When they approach the earth, they may change their orbits due to the gravity of the earth and enter the earth's atmosphere.

These particles move at high speed (1 1-72km/s) relative to the earth. They compress the gas in front of them, resulting in high temperature and electron transition. They give off bright light in the night sky.

In addition, when a comet orbits the sun, it will leave some debris in its orbit. If the comet crosses the earth's orbit, these fragments will also stay in the earth's orbit. When the earth passes through these areas, a large number of comet fragments enter the earth's atmosphere and form a meteor shower. A particularly bright meteor is called a fireball.
