If the moon hits the earth one day in the future, what should humans do?

The distance from the earth to the moon is about 3800000000 meters, the mass is about 7.349× 10 to the 22nd power kilogram, and the average revolution speed is about 1023 meters per second. If the moon hits the earth, its current kinetic energy and gravitational potential energy between the earth and the moon will be released to the earth.

Only the kinetic energy of the moon's rotation reaches 8.4547 times the 27th joule of 10. If the gravitational potential energy between the earth and the moon is added, the kinetic energy of the moon when it hits the earth is two orders of magnitude higher. So much energy released to the earth will melt the surface of the earth and turn the whole earth into hot magma.

If the moon hits the earth, life on the earth will surely die instantly. In fact, it is not as big as the moon. Even if a meteorite with a diameter of 10 km hits the earth, the environmental climate deterioration caused by the violent impact can lead to the extinction of a species. You know, the higher the life form, the stricter the requirements for the environment. The extinction of dinosaurs 64 million years ago was actually due to a meteorite impact of 10 km. What's more, a moon a quarter the size of the earth! Probably can smash the earth to pieces.

How can human beings survive in this situation? In fact, just like human living in a building, being hit by a stone with a quarter of the house at a speed of 30 kilometers per second, human beings will certainly not be spared. The only way is to move as far away from the building as possible. In other words, the earth was hit by the moon, and it is possible for human beings to run as far as possible in the spaceship in order to survive. There is no possibility of survival on earth.

If that day really comes, the level of human science and technology should be many times higher than it is now. With the improvement of science and technology, individual spacecraft will be popularized. By then, mankind should also find a habitable planet. Even if there is no planet suitable for human habitation, human beings will build a large living space station in the universe.
