Mond & formula for acceleration

  1. Mar 16, 2013 #1
    Mond uses the function μ ...
    Instead why not propose a scalar name it "dim" , a function of the location.

    Basic physics says:......................................a=GM/r^2
    but on the outer edge of our galaxy :...a=sqrt(GMa0)/r^1

    So in general a=Cte/r^(dim-1), with
    dim=3 (for us, on a local scale on earth mass is distributed in 3 dimensions)
    dim=2 (for a star on the outer edge of a planar galaxy mass is distributed more like in a plane)

    Is this view too simple ?
    Can a function for dim be derived when the distribution of mass is known on local and global scale?
