Without the sun, you might have guessed life on the planet is impossible. But do you know exactly how the impact of our star's death on the earth?
The sun is not just a bang, but it will take millions of years to death. Continue burning a limited amount of hydrogen atoms, the center shrinks, the outer region becomes wider, and it gets hotter. In this process, the luminosity of the sun will increase by 10% for each hydrogen fusion of one billion years. Increasing the brightness means that the temperature of each planet will rise within the range of the sun's rays including the Earth.
At this point, the water on our planet evaporates and the ice cap melts permanently. Then the earth is like a Venus, like a hot and barren planet. After all the hydrogen burns and the sun has completed its cooling process, it will end a white dwarf, leaving many inappropriate planets
It is estimated that this process will take about 5 billion years. Will someone witness this incident at that time, or have we ever been to? If we are still close, will humans find refuge elsewhere on other planets?
For various reasons, we absolutely need the sun to survive. Without the sun, our planet will become very cold, and all living things above it will die. Plants use the energy of the sun for photosynthesis. This is the process used for nutrition. All animals on the earth depend on the ability of plants to eat plants directly (cattle and people, etc.) or other animals that eat plants (such as cheetahs to eat gazelles and chickens). . If plants are not nourished with the sun, all creatures on the planet will starve to death. The sun did a lot of other things. It is absolutely necessary!
As long as human civilization exists, the sun also exists. Sometimes, with all our skills, work, duties we tend to forget that the sun is essential to our own survival. Prior to the occurrence of power, the sun provided light to us so that humans can actually see and participate in activities to ensure our survival. The sun warms the earth, allowing humans to survive on rocks floating in space. That guarantees that we are not too hot, too cold, not burning or frosting. The sun helps grow our crops, it feeds the food we eat, so we are not starving
We humans are more vulnerable than the earth. The planet will not survive, but it is on the last day of global warming of the earth, catastrophe of nuclear weapons, and even the asteroid's attack will survive by the dying sun. However, it may not be so. We can fulfill our role to prevent self destruction, but there are a few things we do not hand to anymore. Sooner or later, like in a movie, we will be hit by that huge meteor, and Bruce Willis is seldom to help. The earth's magnetic field will change dramatically sooner or later, it may increase exposure to the danger of our solar radiation. A new ice age has arrived. Do you want climate change? You will get it. The mainland and the ocean floor are moving, so in the end New York may find itself in contact with the Sahara Desert. Some of them may occur for tens of thousands of years instead of billions of years. This means that we may see (grab). At least for a while
