In a closed system like our earth all living in displacement processes (watch carefully the nature). Our planet and we are always surrounded by various types of pressure arises at one point an open space = vacuum, the corresponding mass shifts and fills this place out. Conversely create events space, intelligent events focus on this process of displacement at a target and fill this space immediately. Something abstract but based, inter alia, for successful marketing.
To stay with the baker: The people want bread = vacuum. Anyone can learn baking. A baker has built a regulated oven (= integral projection) and the procurement of raw materials and distribution. The sale is running, there is a need = pressure equality.
One thinks he can just bake well and does the same. With the same amount of demand created competition = pressure. Baker 1 kills Baker 2 (and not get caught) = pressure equality.
Bakers one disappears without replacement = vacuum = chance for bakers 2 (does not even need in this case, a separate oven = vaccum = ownerless oven) etc.
