Only when we look at galaxies billions of light - years away, collecting the light they emitted billions of years ago, can we see that the most distant galaxies are moving more slowly than we would expect from observations of nearby galaxies, an indication that the universe has since sped up.

Taking into account that the relatively nearby (in the sky) galaxy M98 is approaching us at 125 km / sec, and thus moving at about the same peculiar velocity but, by chance, toward us, one may speculate that these two galaxies might have been involved in an encounter, but this is currently not much more than wild speculation.
Re 51 Tom P — watched the video; and I agree that the sun does wobble around the center of mass of the solar system; the center of mass itself is not tending to wobble around the sun because conservation of momentum applies to the solar system as a whole (except of course for the forces applied to it by nearby stars, the rest of the galaxy, etc, but those are not varying so fast and so the center of mass should generally be moving along rather smoothly on the same timescale as planetary motions).
