NGC 1277 is unusual among galaxies because it has had little interaction with other surrounding galaxies.

I wonder if interactions between galaxies somehow converts regular matter to dark matter.

Now I'm wondering if three-plus body interactions can cause knots in space itself (and time?) that manifest as dark matter. Clearly such knots wouldn't be particularly dense or else they'd be, well, black holes.

i.e. what if colliding gravitational waves can form static entities? Not necessarily the much-sought gravitons, but something larger(?).
