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.
The gram-force and kilogram-force were never well-defined units until the CGPM adopted a standard acceleration of gravity of 980.665 cm/s 2 for this purpose in 1901, though they had been used in low-precision measurements of force before that time.
