It's still unproven that there's a perfect 1:1 correlation between mass and inertial mass although there is no indication that they differ.drrman said:actually a gram is a unit of "mass" not weight. weight of an object will change with distance from the center of the earth, the mass of something will not vary
W=ma
weight=massXaccelleration and accelleration of gravity changes with distance from the center of the earth
As to whether dark matter will fit into the equation or whether it even exists, the jury is still out. There's a group working on modifications to general relativity that many are hoping will debunk dark matter. If that happens then qute a few equations relating to weight and inertial forces, along with much of general relativity, will be up for a rethink.
