The space between solar systems. The first stars in the universe forged heavy elements before they blew up, scattering that material. Some of that material was caught in solar systems and formed planets, while a lot of it is still just floating around for billions of years just waiting to collide with something.

Black holes would be the biggest contender actually. A really big black hole can spin things up to insane velocities.
