I don't have a PhD .. but here's a rough guess at how it could have happened.
Assuming everything was moving outward, some further out than others, then I suppose it's possible for galaxies to start slipping in towards each other as space-time bends and ripples. If a large star collapsed into a blackhole, it would create that dent in the "fabric of space/time".
http://www.intothecosmos.com/faq/ is a spiffy sight for beginners on the subject of black holes.. http://www.ncsa.uiuc.edu/Cyberia/NumRel/GravWaves. html - and a good sight to understand gravitational waves.
Hopefully someone with more education on the subject can give a better answer ;>
