Like a lover, the Earth and the Moon is a natural object that can not be separated. Size months just 2% of the size of the Earth. very small, but its role is very different with the size of the moon. Not only as a couple & the earth's natural satellite, but also as a brother and parent against our planet. That can not be separated. One of the roles of the moon which is very important is a result of the rotation of the moon itself, namely the occurrence time of lunch & dinner as well as tidal sea water. The part of earth that is near the moon will experience high tide, on the contrary part of the earth away from the moon will experience a low tide. Never guns the hell are you thinking if one day the earth rotates without the moon?. Of course you're not going to be thought of, But scientists say that the moon away of 3.82 cm per year. This is due to the centrifugal force.
What is it centrifugal?
Centrifugal force is the force that will be created when objects move in a circle. The direction of this style will always stay away from the center of the circle. Of spooky yes if the earth spun without the moon. But just calm down, this will happen after a few hundred million years later.
