Rotating relative to what?

Imax said:Baby steps. Instead of looking at a rotating universe, look at another question. Why do galaxies exist? Current cosmological models need Dark Matter and Dark Energy to explain why galaxies can form and don’t fall apart.
You haven't given any logical connection between your previous statements and this one. In any case, GR establishes that rotating cosmologies are possible, and observations set an upper limit on the rotation. See the references given in #13.Imax said:Galaxies rotate and so could our Universe.
bcrowell said:You don't need dark matter to explain why galaxies can form. You only need it to explain why they have the rotation curves they do. In a universe without dark matter, galaxies would still form, but they would have different sizes and rotation curves.
Imax said:You need Dark Matter to explain why observed data does not fit with current theory. Without Dark Matter, galaxies could have different size and rotation (i.e. spin).
Imax said:So Dark Matter could cause the Universe to rotate?
The theory proposes that the universe is constantly rotating around an instant axis, causing the expansion of the universe and the movement of celestial bodies.
Through observations of the cosmic microwave background radiation and the distribution of galaxies, scientists have found evidence of a preferred axis of rotation in the universe.
If proven to be true, this theory could provide a new understanding of the mechanics of the universe and potentially lead to advancements in cosmology and astrophysics.
Yes, there are other theories such as the Big Bang model and the steady-state theory that attempt to explain the rotation of the universe in different ways.
More studies and observations are needed to confirm the existence and properties of the instant axis of rotation in the universe. Additionally, further research on the effects of this rotation on the expansion and structure of the universe may provide more evidence for this theory.
