Ten unsolved mysteries of the moon
1. The Mystery of the Moon's Origin
As for the origin of the moon, scientists have proposed three theories, all of which have flaws, but the Apollo project helped prove that the theory that seems least likely is the best theory. Some scientists believe that the moon was formed together with the earth from a cloud of cosmic dust 4.6 billion years ago. Another theory is that the moon is Earth's child, perhaps carved out of the Pacific. However, the results of the Apollo lunar landing expedition showed that the structural components of the earth and the moon are very different. Some scientists have put forward another hypothesis, the capture theory. They believe that the moon accidentally broke into the earth's gravitational field and was locked in its current orbit. However, it is quite difficult to explain the mechanism of this process theoretically. Therefore, all three of the above theories are untenable. As Dr. Robin Britt said: It is easier to explain the absence of the moon than its existence.
