Questions about the accelerating Hubble expansion

In summary, the accelerating expansion of the universe, as evidenced by observations of distant supernovae and cosmic microwave background radiation, raises critical questions about the nature of dark energy, the overall geometry of the universe, and the validity of current cosmological models. Researchers are investigating potential explanations, including modifications to general relativity and the properties of dark energy, to understand the implications of this phenomenon for the fate of the universe.

that's why I spoke of expansion in this post, and not acceleration
And did so wrongly if you didn't mean what I said in my previous post. Expansion and acceleration are not the same thing.

Kairos said:
dark energy favors expansion contrary to gravity
No, dark energy favors accelerated expansion.

@Kairos you are clearly not engaging with what the rest of us are trying to tell you and we are just wasting time at this point. So this thread is closed. Please re-read the responses you have gotten more carefully.
