If there is no anti-gravity force, then how can an galactic scale empty section be "pushing" us toward the Great Attractors....

Some decent visualizations linked, and an original one on Utube from a French team is one of the coolest large scale animations i've ever seen...

Are you just wondering what 'pushing' means in this context? Or speculating about the existence of anti-gravity?
I'm pretty sure that this is just interpreting as region of low density as 'pushing' because it 'pulls less' than a region of average density would.
This is similar to how electron 'holes' in a metal's atomic lattice can be treated as positive particles.
If it's worth saying, but not worth its own post, then it goes here.
