What would happen to Earth if the moon disappeared? Can humans still exist?
The moon has a profound effect on the earth and shapes the entire planet. For as long as human beings can remember, the moon has been moving around the earth in its own orbit, and the resulting gravitational pull attracts the water on the earth, causing it to move together and form tides. Before there was no moon, the temperature difference between day and night on the earth was extremely large, and it was completely unsuitable for human habitation. However, because of the gravitational force of the moon on the earth’s seawater, the speed of the earth’s rotation and revolution was slowed down, thereby reducing the temperature difference and bringing four seasons to the earth. Only living creatures on earth can live normally. It can be said that the moon has a great impact on the earth. If a nuclear bomb is used to attack the moon, what will happen to the earth? How will our world change? You might think this assumption is crazy, but in past history, this proposal has really come up.
