Friends do you know how fast we are spinning together with earth? It's enough for you to make dizzy on listening. We are spinning through the space with the Earth at the speed of 1,600 km/h. If it suddenly stops or starts spinning fast then we would be thrown out into the space but don't worry Earth wouldn't spin 800 times faster than it does now for it to happen.
WAIT!!!! Then why don't we fall off the Earth. Here are some of the reasons why this does not happen because all of us are held to Earth by the gravity. Well it's the general theory of relativity proposed by Albert Einstein which explains that any mass creates a disturbance in space and it generates a field of gravity which is directly proportional to the mass of the object. So always the smaller object revolves the bigger objects as Moon revolves and Earth revolves the Sun. It also depends on the distance that separates them from the center.
