If the sun disappears, what will the earth look like? What will be the result of mankind?

If the sun disappears, it will take eight minutes for human beings to feel it. How can life on earth survive?


Among the five elements, gold, wood, water, fire and earth coexist. Although water is the source of all things, the sun is the same as water. It is not only the sun, but also an indispensable part of life, which constitutes an important part of the earth’s ecosystem. If there is no sun, plants will lose the ability of photosynthesis, will wither and die, and if there is no water, everything will dry up and die.


If humans and animals lose the sun, not only the body function will be greatly affected, but also the human immune system will have a variety of failures. It can induce various diseases. The sun is as important to the earth as man’s need for air. The sun gives people the rules of life. People are used to working at sunrise and resting at sunset. The sun brings warmth, vitality and light to the earth.


So far, experts predict that the sun is 4.6 billion years old. The sun has a life span of more than 10 billion years, and now it is as old as middle age. Scientists speculate that the life span of yellow dwarfs is about 110 years old. Once they enter their old age, they will experience supernova explosion and eventually become a white dwarf. The energy of supernova explosion is comparable to the total energy radiated by the sun in a lifetime, which is also the source of cosmic rays in the universe. The explosion of supernovae will make the surrounding temperature rise. If the sun explodes, the planets in the solar system will be baked by the high temperature of the sun. At that time, the water on the earth will be evaporated, and the surface temperature of the earth will rise to more than 60 degrees. All creatures are likely to face a disaster.


If one day the sun does not experience the process of supernova explosion, but suddenly disappears, what will the earth look like? What will happen to human beings on earth? According to experts’ prediction, the distance between the sun and the earth is about 150 million kilometers, and the light matter consumed by the sun reaches 4 million tons per second. If this kind of energy is converted into the energy produced by photosynthesis of plants on the earth, it only takes one second. If it is used by human beings, it can last about 2700 years. It takes about eight minutes for sunlight to reach the earth. If the sun suddenly disappears from the solar system, it will take eight minutes for people on earth to notice. All of us will find that the earth is dark without any light, and the world suddenly quiets down.


If it is in summer, the temperature of the earth will drop by more than ten degrees or more, if it happens again in winter. Then all living things will suffer, and the temperature of the earth will soon drop to more than ten degrees. During the time when the sun disappears, the temperature of the earth will slowly decrease, and finally the earth is likely to become an ice hockey.


For this reason, human beings have come up with various ways to replace the sun. Some countries invented the “artificial sun”, which is expected to replace the sun and continue its mission.
