I recently read another article suggesting the universe expansion might be anisotropic. The most interesting part was mentioning that data from supernova standard candles had been normalized to fit with the assumption that expansion is isotropic.

Once they removed those adjustments to the data it turned out that expansion is a local phenomenon only for our galaxy and nearby galaxies.

Dark matter != dark energy - dark energy is what is proposed to be the cause of the expansion of the universe, dark matter is what binds galaxies together.

For others, the article mentioned is likely: https://phys.org/news/2019-11-evidence-anisotropy-cosmic.htm...

Ah, yes, sorry. I didn't realize this article talks about dark matter, not dark energy.
It's in the first three words of the headline though
Also worth noting is that it isn't necessarily that expansion anisotropic. It's the acceleration of expansion that is anisotropic.
