Putting the notion of the big bang and expansion aside for the moment,
If one considers that the mass outside of our bubble is attracting
everything in our bubble to it, then objects closer to the wall will
be hurtling toward the wall with a much greater velocity than those
farther from the wall, resulting in a greater red shift from the
objects closer to the wall.

The expansion is observed to be isotropic, which would imply
that an attracting force would need to be likewise (i.e., not
"lumpy"). In other words, the attraction would come from what
would appear to be a uniform shell of attraction surrounding
our cosmic horizon.

Now, what is the net gravitational field inside a uniform
spherical shell? It's nil. Nada. Zilch. Nothing.
