The article below is a reprint of an article that appeared in the study magazines "Science" and "Gakushu".
The article "When will the earth die? has more detailed explanations and new information.
When will the earth be destroyed?
The earth is made of metal and rock, so there is absolutely no way that it can easily explode. Even if human beings were to perish due to continued environmental destruction or nuclear war, the earth would still exist in the universe and orbit the sun in the same way.
However, it seems that the day will surely come when the earth will disappear from the universe.
It is said that the sun will die five billion years from now. When the sun dies, it will become a small pale star, but before that, it will become much larger than it is now. At that time, the sun will become so large that it will swallow the earth and burn it away without a trace. At that point, the earth will disappear from the universe.
Therefore, it is believed that the Earth has only 5 billion years left to live.
