Despite the fact that man has not changed one iota physiologically, the technological advancements that have occurred in the last fifty years would normally have taken at least two hundred years to make. There's a reason. We had help. That help came from technology found in downed alien spacecraft.
many other objects.The strength of the gravitational force between two objects depends on two factors,mass and distance. The Mass of the Objects The more mass two objects have,the greater the force of gravity the masses exert on each other.If one of the masses is doubled,the force of gravity between the objects is doubled.
Gravity is probably the ultimate driving force of mass wasting. The force of gravity pulls all things on the planet toward the center of the Earth. Without gravity, mass wasting would not occur. But unlike many of the other factors, humans have no influence or control on gravity.
