and what is the great attractor ?
While the great attractor without doubt has its share of black holes, I doubt that any one of them accounts for a percent of its mass.
The distribution of mass of a black hole is up to debate, but it doesn't matter. It has the same mass regardless of how that mass is 'anchored'.if the black hole is anchored somehow to subspace ? The mass would be incalculable.
You make it sound like the big bang happened at a point in space. You can point to it, but not in any of those directions.You can point to it ? Are parts of space expanding at different rates to others ? That would be the only way concievable that could lead to collisions.
Galaxies collide for the same reason planets do (like our little encounter with Theia). Their paths cross mostly due to the pull of a local central mass (one of the attractors) that prevent the objects from distancing themselves from each other.
Planets orbit stars, stars galactic centres, if galaxies orbit attractors they are not falling away from each other vis-à-vis the OP's point. Thus the larger affects the smaller, or vectors at conflict interact, this would lead them to be in freefall collision unlike objects on vectors that are distancing without exterior influence.
