  This is the third one of three papers I have presented as an application of
the Basic Unit System concept, a complex mathematical unit presented in The
Basic Unit System concept and The Principle of Synergy. In this case this Bus
concept is used as a powerful tool to obtain again those gravitational field
equations of normal planets, deviation from them as that of Mercury, but also a
proposal made by the astronomer Micheal Disney in his book the Hidden Universe
about Dark Matter. The emerging proposal is then to see the cosmic system as a
Steady Open System, state that is continually exchanging energy, matter and
information, and in it Dark gravity bodies can be seen as gravity compensators
of the whole system. But then appear new forces when the whole system is
considered.
