Is "empty space" empty (only reasonable answers)

No. 99.9999999% of all galaxies are moving away from our Milky Way, at a speed far in excess of the gravitational escape velocity of Milky Way, meaning they will never reverse course and come back towards us. Only 0.00000001% of all galaxies are moving with any hint of coming closer or merging with our Milky Way any time in the future.

It would be the same with any other galaxy.

On the scale of the visible universe, Expansion of universe vastly overmatched Mutual attraction between galaxies for all but the closest galaxies.
