Potentially a very dumb question, but seeing the difference between cyclones and hurricane on earth (clock-wise, anti-clock-wise)...

Does it mean that we are, potentially, on one of two poles(?) of the observable universe, if we're observing most galaxies around us rotating a certain way?

That would be super cool to find out! And then it also begs the question, is there something at the center that unites the two poles? If so then what is it!

It would also imply that our whole universe is rotating - the only reason this happens on Earth is because of our planets rotation and the Coriolis effect.

I've been following this news for the past couple of weeks-- in essence your statement is what they are hypothesizing, and that the "something at the center that unites the two poles" might be that we are within a black hole. https://en.wikipedia.org/wiki/Black_hole_cosmology for the curious.

“The universe is an orb and that orb is rotating causing all the other stuff to spiral.” This was a long held theory of mine because I could not understand why a galaxy would spiral.

I think there is a men in black scene, where an alien is rotating the universe globe like a toy they are playing.

Doesn’t it have to spiral? Think of the gravity well, anything not orbiting is just falling. The only things not racing towards the black hole at the center of the galaxy are the ones that are orbiting.

It can be directly sucked into the center. A spiral implies a lateral movement plus a centripetal force

Right, I guess what I am saying is if it didn't spiral, it wouldn't be a galaxy for "long." It would just be a super massive black hole.

The trick to having a galaxy is for mass to fall towards the black hole and miss it all the time.
