Non - equivalence Graceli inertia gravity. If you believe that the attraction depends on the chemical conditions [liquids and solids tend to sink and gas to rise], and conditions in relation to age mates graceli magnetic equatorial and ecliptic, and internal [inside stars and particles], so this not confirmed in relation to an equivalent inertia and gravity, as gravity itself becomes relative to the physical and chemical conditions, and the same happens with the supposed inertia.
