    Moon
In summary, the moon and Earth have a 1-1-spin-orbit-coupling, causing us to only see one side of the moon from a fixed position on Earth. However, due to the elliptical orbit of the moon, we can see about 55% of the moon's surface due to effects called libration in longitude and latitude.

It's a simple basic question.But I don't know the answer exactly. Why we can't see the other side of moon?

You only see one side of the moon because the moon and the Earth have a quasi 1-1-spin-orbit-coupling. This means that if the moon has rotated 360 degrees around it's axis, it also has completed one full orbit around the earth. Thus you only see one side of the moon, seen from one fixed position on the earth.

However since the orbit is not circular but elliptical you get two effects called libration in longitude and libration in latitude. They result in a kind of east-west rocking and a north-south-nodding up and down. Due to these effects, we actually see about 55% of the moon's surface...a little bit more then half the moon surface

1. Why can't we see the other side of the moon?

The reason we can't see the other side of the moon is because it is tidally locked to the Earth, meaning that it takes the same amount of time for the moon to rotate on its axis as it does to orbit the Earth. This causes the same side of the moon to always face the Earth, making the other side invisible from our perspective.

2. Can we ever see the other side of the moon?

Yes, we can see the other side of the moon with the help of spacecrafts. In 1959, the Soviet Union's Luna 3 spacecraft captured the first images of the far side of the moon, and since then, other spacecrafts such as NASA's Lunar Reconnaissance Orbiter have provided detailed images of this hidden side of the moon.

3. Is there a dark side of the moon?

No, there is no dark side of the moon. The far side of the moon experiences the same amount of light and darkness as the near side. However, the term "dark side" is often used to refer to the side of the moon that is not visible from Earth.

4. Why is the other side of the moon so different from the side we see?

The far side of the moon has a much thicker crust and more craters compared to the near side, which has a thinner crust and a smoother surface due to volcanic activity. This is because the far side of the moon cooled and solidified much faster than the near side, which allowed more time for impacts to occur and create craters.

5. Can humans ever visit the other side of the moon?

Yes, it is possible for humans to visit the far side of the moon. However, it would require advanced technology and resources to establish a base or colony on the far side, as communication with Earth would be more challenging without being able to directly transmit signals through the moon to Earth. Some space agencies are currently considering plans for future missions to the far side of the moon.
