With the present knowledge of the formation of the universe reference Universe ** The formation of the earth Reference Before the formation of the earth, there were many asteroids in the universe revolving around the sun, and these planets collided with each other to form the primitive earth. A large amount of gas is ejected from the inside of the earth, which carries a large amount of water vapor, which forms a circle of atmosphere surrounded by the periphery of the earth, the position of the earth from the sun is not too close to the water vapor is evaporated by the sun, and the size of the earth itself has enough gravity to pull the atmosphere, so the earth will have a unique atmospheric environment, and the atmosphere begins to rain after the formation, and the original ocean is formed.
About 4.7 billion years ago, dust gathered in the universe to form the Earth and the other planets of the solar system in which it is located. At that time, the air did not contain oxygen, but contained a lot of carbon dioxide (carbon dioxide gas) and nitrogen.
Originally, the Earth was very small, but it was constantly impacted by small stars in the universe, and its size continued to increase. When it hits, the energy gathers, the temperature rises, and eventually melts into a liquid.
Soon, the number of star impacts decreased, and the temperature of the Earth's surface decreased, forming the Earth's crust. This is the surface of the earth today. However, magma in the Earth's interior is constantly erupting, forming a large number of volcanoes. The water vapor in the volcanic ash cools and condenses into water, which forms the ocean.

Do more massages. Let yourself learn to relax.
Don't stare at the computer screen for a long time, and don't work for a long time when you have time, try to let yourself see the scenery in the distance, and decompress yourself appropriately.
Unless it's a rainy day, remember to wear sunglasses when you go out. Too strong light, or long-term work will make people's brows naturally wrinkle, and there will be a "Chuan" type wrinkle between the eyebrows after frowning for a long time.
If you can, you can also go to a beauty salon and let a professional masseuse help you do a massage.
In short, it is necessary to relax yourself appropriately and not let yourself be under too much pressure.
A simple and effective way to relax is to use the relaxation style of yoga.
In a person's room, turn off the phone, turn on the stereo, and put on something relaxing.
Untie the bundle of hair and gently rub it into your scalp with your fingertips.
From top to bottom, repeat several times, then come to the eyebrows, and gently rub and press with your fingertips.
The length of the whole process can be determined by your preference.

Suppose I become an astronaut. I'm going to fly a faster-than-light spaceship to explore space, and I'm going to other planets to find planets suitable for human survival.
If you become an astronaut, I happen to be on duty at the space station. An unidentified asteroid was coming from the siren, heading towards Earth at a speed of tens of thousands of kilometers per second. Hearing the news, I hurriedly put on my spacesuit, piloted a faster-than-light spaceship, and went to reconnoiter the situation.
Taking off, I only heard a sound of Yu Xun, "The spaceship is flying away." I first found the asteroid, examined the laser cannon, fired at the asteroid, and the asteroid was blown to pieces. The mission was accomplished, and I flew back to the space station.
A few days later, I received a new notice, because of the serious damage caused by human beings, the earth is now seriously short of water, and the air is polluted. Please go to another planet immediately to find a suitable place for human habitation. When I heard the news, I immediately set up a laser speed spaceship to look for it.
The first place I came to was Mars, because it's very hot, so it's not suitable for human habitation. I came to a planet I didn't know about, and I scouted here and saw that there was enough water for our ancestors to survive here, and at the same time there was enough vegetation and an inexhaustible source of energy. So, I hurried back to Earth and migrated all the creatures on Earth to this planet.
Suppose I become an astronaut.

According to Theravada Buddhism:
1. The king's call is not as good as the law, because the precepts stipulate that monks cannot dig up land (Article 10 of the Ninety-two Boyiti (Confession) Law). If the king knowingly calls for it, then he has created bad karma. If the king does not know, he can advise. >>>More
