Mond & formula for acceleration

[Alain De Vos]

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?

Hello,

Thank you for your interesting proposal. While I understand your reasoning behind using a scalar name "dim" and incorporating it into the gravitational force equation, I believe it may be too simplistic to accurately describe the distribution of mass in a galaxy.

Firstly, the concept of "dim" assumes that the distribution of mass in a galaxy is uniform, which is not necessarily the case. Galaxies are complex systems with varying densities and structures, and the distribution of mass can differ greatly depending on location.

Furthermore, the value of "dim" would also depend on the type of galaxy being studied. For example, a spiral galaxy may have a different "dim" value compared to an elliptical galaxy due to their different structures and mass distributions.

In terms of deriving a function for "dim" based on the distribution of mass, it would be difficult to do so as there are many factors that can influence the mass distribution in a galaxy. These could include the presence of dark matter, interactions with other galaxies, and even the age of the galaxy.

Overall, while your proposal is intriguing, I believe there are many complexities involved in accurately describing the distribution of mass in a galaxy. Further research and analysis would be needed to fully understand and quantify this phenomenon. Thank you for sharing your thoughts on this topic.
