Why do we always see the same side of the moon?
First of all, the "dark side" means that radio transmissions from Earth don't get there. There is day and night on the Moon just like it is on Earth. Moon is facing us always the same way, because it is "tidally locked".
The Short Answer
First of all, the "dark side" means that radio transmissions from Earth don't get there. There is day and night on the Moon just like it is on Earth. Moon is facing us always the same way, because it is "tidally locked". When you have two things spinning around themselves and around each other, eventually the lighter one will slow down enough, so that it'll always face the bigger one. Given enough time, the same will happen with the bigger one. Currently the Earth is being slowed down, little by little, by the Moon creating tides.
