OK, so you've found matter being shot out of the center of a galaxy where the black hole is, congratulations, but what other impossible amazing things you can find if you go look.
So now go find a galaxy tumbling with respect to the universe while maintaining its structure.
How common are they? *Every* galaxy is doing that, but you'll need to find one that's moving fast enough to observe.
Bonus points, for breaking everyone's model with an impossible find.
Holy Grail bonus points, if you find one and calculate the outer stars are moving faster than light as they tumble.
