Why we see only and always the same side of the moon?

Yeah, it's tidally locked. Because the moon isn't uniform in density and mass, one side of it is pulled more by the Earth's gravity, and therefore is now aligned with the Earth. That is the side we always see.

The moon rotates around the earth ever 27.3217 days. It also rotates on it's axis every 27.3217 days. So only one side is facing the earth at all times.

Bowery if you where to go every plae on earth, everyday for 29 days, and take pictures of the moon, an map them, you would see 58.8% of the moon.

Because 1 rotation and 1 revolution are not the EXACT same time, in several million years we will see the dark side of the moon.

I forget what the term is, but the rotation of the Moon is a speed that is perfectly relative to the speed at which it orbits the earth. This makes it appear as if it never spins to us.

Scientists say that this type of orbit is probably really rare in the universe. Odd considering nothing is rare in something that has near infinite Exoplanets. Lol

The moon goes around the sun every 29 days. The moon complete one rotation every 29 days. Because they match, one side is always facin us at all times.

It spins at just the right rate where the same spot will rotate over your spot...

if you travel far away you will see a "different" moon

Tidal locking. The same thing has happened to Mercury and the Sun.
