#3At this point I'm open to believing our Universe is in a black-hole-like structure.

#4> This preferred direction of spin might be due to one of two reasons: either our entire universe exists in a black hole, or astronomers have been measuring the universe’s expansion incorrectly
This is the subtitle of the article. It’s such a great summary!

#5Now if only we could see inside a black hole.
Re: James Webb Space Telescope reveals that most galaxies rotate clockwise
#6If we were on the other side of those galaxies, wouldn't they look like they were spinning counter-clockwise? Or are they measuring spin some other way?

I'm not well versed in celestial mechanics, but I see a lot of "we're in a black hole" comments so far, and I'm super curious as to whether or not we know why black holes prefer a direction of spin. Can you (or anyone, really) shed light on that?

The point is that you’d expect a roughly even distribution of clockwise and counterclockwise spins, not all of them to rotate in the same direction.

#9Potentially 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?

#10Unless you're looking at them from the other side, in which case they rotate counter-clockwise!
Or maybe they're just billboard sprites, always facing the camera, with clockwise animations.
