No. You never met or spoke to a person who said the sun wasn't visible
from his home town, and you never will.
Yes only one side of the moon is always facing the earth.
Once . The Moon is tidally locked to the Earth, with one face of the moon always facing the Earth, and the other side never facing the Earth .
The side that's visible.
Because one face is always pointed towards the Earth.
tidal lock
As the earth rotates on its axis, one side will face the sun , that side will get day and the other side will be dark, so that side will have night.
It never does because the same face of the moon is always pointed at Earth. This is due to the fact that the moon revolves around Earth at the same speed it rotates on it's axis, so Earth remains in the same relative location in the sky on the moon.
The side of your face is called the profile
Our moon makes one rotation on its axis, in the same time it takes to orbit the earth once, so the same side always faces the earth. This is no coincidence, since the moon is said to be 'tidally locked'. The moons mass is biased on one side, meaning that this one side (the now near side) which causes this one side to face Earth. Other large moons in our solar system also experience this tidal locking with their parent planet.
During one trip around the Earth, the moon rotates one time, because its rotation and revolution are about the same. That is why we only see one side of the moon (the near side) and never the far side.
15 days one side 15 days other No it's always the same face. Because the moon spins on its axis exactly once per its orbit of the earth. It's a tidal friction effect. In zillions of year's time the same face of the earth will always face the moon also.
