The ΛCDM model assumes that on scales larger than a few hundred million light-years, the universe is smooth and uniform. That makes a huge void like the KBC a serious challenge.

The computer model also makes use of new mass estimates for other galaxies within the Local Group—a galactic group that hosts the Milky Way and Andromeda, among others.

But the only way to get to a new prediction about the eventual fate of the Milky Way will be with even better data.” DOI: Nature Astronomy, 2025. 10.1038/s41550-025-02563-1 ( About DOIs ).
