Gravity is transmitted by slow-moving waves of large wavelengths.
Their operation can be wittnessed by observing the behavior of a canine
suspended over a large vertical drop. Its feet will begin to fall first,
causing its legs to stretch. As the wave reaches its torso, that part will
begin to fall, causing the neck to strech. As the head begins to fall,
tension is released and the canine will resume its regular proportions
until such time as it strikes the ground.
