Question question about distribution of dark matter.

[Greenlight]

i hear that the galaxies are not massive enough to spin at the rate we observe and thus dark matter. Most common is a halo distribution model. My question is would more massive mass satisfy the distribution requirements. If mass weighed more in the past? Mass increase is a relativistic effect. Cosmology doesn't currently apply relativistic effects to the universe as a whole. If they did how would this factor in?

 

[Questioner]

Layperson's perspective,
It would distribute the mass largely appropriately,
But that greater mass would decidedly affect all the gravity interactions between visible bodies.

Back to the drawing board, imo.

There is a published theory on this point. It uses Dilation (relativity) to explain the issues. At the time I thought it made sense and am surprised it has been largely ignored. It might be worth trying to look it up.

I found a paper that might be what you’re looking for. It discusses the motion of stars in galaxies and proposes a solution using gravitational time dilation. The paper suggests that the problem of the motion of stars in our galaxy can be solved by applying a gravitational time dilation factor in combination with Newton’s theory. This approach considers the flow of time in a weak gravitational field, such as where the Sun orbits the Milky Way, and applies a time dilation factor to explain the observed motion of stars.
