The domain of a force i.e. the extent to which it can be perceived is defined by the inverse square law. (F -> 1/r²).

 

If we take the limit of this over infinite distance we can see that the magnitude of the force approaches zero but actually does not become zero.

 

This has implications in the context of a very large (but not infinitely large) Universe.

 

This means that even the most distant quasar can exert its footprint in our galaxy, for example.

 

Also as we know radiation from the most distant quasar does in fact reach us, although we detect it after an appreciable time.

 

May our Universe could be biased in one direction (of expansion) (based on random distribution of galactic clusters in different "directions") and it subtly tugs the more remote less dense quarters through a very small force acting over a very large distance.

 

How realistic is this model?

 

Please express your viewpoint.

Space can expand faster than light can travel. These forces are thought to propagate at the speed of light.

I had read something similar few years ago, that astronomers believe to observe the effect of a great concentration of mass beyond the horizon that limits our present observations, as inferred from the speed of the matter near this horizon, which seems to be attracted.

 

That would be an indirect observation of something beyond the horizon.
