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.

Around 70,000 light years away from Earth, a dwarf galaxy is spiraling in a polar orbit. The galaxy, known as Sagittarius, has crashed through the Milky Way's disc at least three times in the past ...

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 ).

About 30 percent of the dead neutron stars in the Milky Way’s galactic underworld will eventually be ejected into intergalactic space, flying off to brand new systems, Sweeney says.

The Milky Way contains between 100 billion and 400 billion stars, but the exact number is difficult to determine due to the galaxy's vast size and the presence of dust that obscures our view.
