Attraction continues beyond the dark matter region and gradually weakens. The dark matter is spread uniformly inside, then gradually thins outward. Area inside ring 1: 1× mass Area inside ring 2: 8× mass Area inside ring 3: 27× mass Area inside ring 4: 64× mass Dense cloud of stars surrounding center of mass.

The circles are only orbital/reference rings. They remain barely visible so you can compare the four regions without confusing them with the information layers.

What the three switches show

Dark Matter Density
The light-blue cloud and dots show dark matter spread evenly through the inner region, then gradually thinning outward. The color stays blue; only the amount shown decreases.

Area Enclosed Mass
Each larger ring encloses more of that dark matter. The mass belongs to the area inside the ring, not to the star.

Star Attraction to Center
The red arrows show the inward pull on each star. The red haze outside the dark matter region shows that gravity continues past the edge and gradually weakens.

About this model

This interactive model illustrates observed galactic rotation behavior and possible mathematical representations. It does not claim to identify the unknown physical cause.

Note by Joe Cummings: I do not believe in the "dark matter" theory, nor say it isn't so. What I do believe is what we see. To me, it is the hand of God controlling this currently unexplainable observation. I'm sure God will make the details of how clear to us moving forward. For now, let us marvel in Creation...
