Giant-Impact Hypothesis: Why Doesn’t The Moon Fall on The Earth?

What is the origin of the moon, the giant impact theory?

The moon is under the gravity of the earth.

But why doesn’t the moon fall to the earth?

In fact, the moon is falling to the earth.

However, the moon cannot approach the earth rapidly.

Because the surface of the earth is round.

The gravitational pull of the earth is generated toward the center of the earth.

In other words, it works vertically to the surface of the earth.

It is true that the moon is attracted by the gravitational pull of the earth, but because the earth is round, it does not immediately fall to the ground, but continues to rotate around it.

So when did the moon begin to orbit the earth?

Hundreds of millions of years ago, a celestial body about the size of Mars collided with the Earth.

At that time, the scattered celestial debris and the fragments of the earth were united, and the moon was born.

This is called the “giant-impact hypothesis”.

There used to be a superstition that animals live on the moon.

  • Crab (Europe)
  • Rabbit (Japan)
  • Crocodile (Vietnam)

Similarly, I clicked in the area, but there was a lunar custom.

In light of the lunar pattern and the giant-impact theory, it is in the northwestern part of the drawing.
