The energy of the sun is about to run out, what should the earthlings do in the future? scientists answer
The earth has been carrying the existence of hundreds of millions of living things. The earth continues, and all creatures that depend on the earth can also prolong and multiply. When the earth ends, all life attached to the earth will also disappear.
The lifespan of the earth is affected by many factors, the most familiar one is the impact of planets from the universe, but the probability of this kind of thing happening is not high, and it will almost never happen in 10 billion years. After research, scientists have found that if we perish, it is likely to be related to the sun, and the life of the sun determines how long human beings can survive on the earth.
Studies have shown that the lifespan of the sun is only 10 billion years, and it is currently 4.57 billion years old. After another 5 billion years, the hydrogen in the sun will be exhausted. At this time, the sun will enter the red giant star stage, and the helium core in the sun will resist Gravity shrinks, and at the same time the temperature of the core also begins to increase. The temperature rise causes helium to start to fuse into carbon, and the heat generated by the fusion causes the outer layer to expand at an accelerated rate. When the sun enters the stage of a red giant star, its diameter will become 200 times its original size. At this time, it will devour Mercury and Venus and come to the edge of the earth. The earth will receive high-temperature heat, and all liquid water will evaporate. It will turn into a ball of fire, and all living things on it will cease to exist, so what should the earth's 7.4 billion people do by then?
Scientists have long stated that human beings have not become extinct after 5 billion years, so we have left the earth long ago. We have already been able to travel between stars, establish homes on other planets, and even build countless planets suitable for human survival in the universe. There is no need to worry about what the earth will become!
