Clouds seem oblivious to Earth's gravity and show absolutely no tendency to fall to the ground. Yet they are comprised of water droplets many times the density of the surrounding atmosphere, and therefore defy the laws of floating bodies. It might be argued that the viscosity of the air and air resistance prevents them from falling. This could only slow the rate of their fall. This phenomenon is usually explained away with the argument that "Brownian movements" are responsible. It has been detemined that unequal molecular bombardments at any instant on opposite sides of each particle produces the constant motion, allowing the clouds to remain. This phenomena in itself creates he same enigma as the inability of clouds to fall. Over a period of time the bombardments working against gravity will actually be weaker than the bombardments working with it. The velocity of bombardment will be slowed by gravity. Any thoughts?
