Xelasnave. 1947 I'm not sure I understand your premise.
Well you won't be any help I was hoping you could explain it to me.
Consider it this way, very simple and I know that is dangerous,....
(I will use every day objects to enable visualisation)
Take a string from on side of the room to the other, the string represents one trajectory of the billions in play in the reality I seek to create.
It can also represent the vast distances a particle (loose term for whatever travels along the trajectory) may travel before it becomes involved in the interaction I try and describe.
In the middle of the string imagine two pool balls or if you prefer billiards use the two billiard balls.
One white one red and set them say one foot apart with the string thru the center of each.
Hold that thought.
Along the string small balls travel, think small ball bearings.
They travel in both directions and travel almost uninterpreted thru each ball , in one side out the other and continue across the room to and past the end of the string..
Some ball bearings don't get thru the billard ball but remain trapped inside.
Later we can work out what happens.
From the north side of the room 200 ball bearings reach the first ball 10 pass thru and exit to reach the other Billard ball and pass thru it and 9 stay in that billard ball those that pass thru continue on to and past the end of the string.
From the north side the same.
My question at this point is would the two billiard balls be pushed together.
As to dark matter if such an effect was real the manifestion of gravity may be very different.
As to why I will leave for the moment for you to think about the simple picture and if the balls could respond by moving toward each other if not the idea ends here.
Thanks for thinking about it.
I hope it helps site traffic and draws in folk interested in this sort of thing ...we can set them straight after they have been here a while.
I suppose I think it would be easier to hold galaxies together from an outside force rather than an internal force and trying to determine if the could be hope in such a simple change in how we see things.
