What will the earth look like in 200 million years?

The earth exploded? Unlikely. If the earth is going to disappear, there is only one possibility, being swallowed up by the sun. That is, after 20 billion years, the hydrogen atoms in the sun will burn out, become supernovae, and then devour the earth. Other possibilities are: being swept by gamma rays of neutron stars, being swallowed by black holes, and being hit by huge meteorites.

But these three possibilities are very small and can be basically ignored. The earth won't explode, but it may run out of energy. These are the consequences caused by human beings themselves. Maybe in the future, the earth will become a dead planet like Mars now, without water and atmosphere. There is also a saying that the earth or a planet suitable for life has cycles.

First of all, this planet will gradually form a planet rich in substances suitable for the formation of life, then plants and single-celled animals will appear, evolve into multicellular animals, and finally form highly intelligent animals. After the formation of high IQ animals, they will slowly absorb and consume the energy of this planet like moths until the energy is exhausted, then all the animals and plants on this planet will perish. The earth began a new evolution, and gradually became a material-rich planet. You must have seen the American movie The Day After Tomorrow?

Human beings wantonly destroy the environment, leading to the early arrival of the "freezing period", but after the "freezing period", the earth has become a clean and beautiful planet. I once saw a documentary, which probably said that if human beings were destroyed, you would not find any information about human existence in 65438+ 1 100 million years. Now the earth is 5 billion years old, but humans can only discover what the earth looked like 200 million years ago at most. It will be 4.8 billion years before man knows what the earth will look like. Can you say that human beings must be the first intelligent life on earth?
