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.
However, for most applications, gravity is well approximated by Newton's law of universal gravitation, which describes gravity as a force which causes any two bodies to be attracted to each other, with the force proportional to the product of their masses and inversely proportional to the square of the distance between them. Gravity is the weakest of the four fundamental forces of physics, approximately 10 38 times weaker than the strong force, 10 36 times weaker than the electromagnetic ...
