Black hole cosmology suggests that the Milky Way and every other observable galaxy in our universe is contained within a black hole that formed in another, much larger, universe.

The theory challenges many fundamental models of the cosmos, including the idea that the Big Bang was the beginning of the universe.

It also provides the possibility that black holes within our own universe may be the boundaries to other universes, opening up a potential scenario for a multiverse.

Okay so I have a basic understanding of orbital mechanics, I would say astronomy and astrophysics is a hobby of mine, and my content subscription list is filled with space nerds talking about nerdy space stuff.

I do not understand how the rotation of the milky way could be making it seem as though other galaxies are rotating a specific direction.

I understand if you spin in place and are looking at something above you that's spinning in a certain way, it might appear to spin the opposite way it is relative to the floor, because you're spinning faster. However, my problem understanding stems from the fact that the milky way is huge and we are rotating around a very large axis, not at a rate that my common sense tells me would be noticeable.

Maybe I'm just not giving NASA and ESA enough credit for their measurement capabilities, but I don't get it.

And maybe I'm so far off base someone is face-palming into their screen in disappointment that I could choose be so wrong.

If anyone could explain, or post a link to a space nerd talking about nerdy space stuff thats relevant to the answer, please edumacate me!

Yeah it's like either I don't understand 3D space or they don't. Clockwise to what? What if you go stand on the South Pole, does it all reverse? Maybe they need to read Enders Game again.
