And the center of the earth is made of metal. In other words, the earth is made of metal and stone. Is there any possibility that such an earth could explode?　I have never heard of a stone on the street suddenly exploding or iron metal exploding. In other words, stones and iron usually do not explode. Therefore, it is safe to assume that the earth, which is made of stone and iron, will never explode.
Next, let us consider whether or not the earth will disappear. What does it mean that the earth will disappear? Does it mean that one day the Earth will suddenly disappear from the universe?　The Earth has existed in the universe for more than 4.6 billion years. It is hard to imagine that it will suddenly disappear from the universe.
However, the fact is that the day will come when the Earth will disappear from the universe. The sun will get bigger and bigger, so big that it will swallow the earth. The earth will then be burned by the sun and disappear from the universe. Of course, all the animals living on the earth will die.
But don't be frightened. This will not happen for another 5 billion years. It is true that in 5 billion years the earth will be swallowed up by the sun and disappear. However, what happens 5 billion years from now has nothing to do with those of us who are alive today. Therefore, there is no need to worry about whether the earth will disappear soon.
However, we do not know if it is possible for humans to live on the Earth indefinitely. Currently, the Earth's population continues to increase, and it is poisoning the planet. If this situation continues indefinitely, the earth may soon be uninhabitable.
We need to think seriously about what we can do to prevent further environmental degradation, rather than the disappearance of the Earth.
