Black hole cosmology suggests that the Milky Way and every other observable galaxy in our universe is contained within a black hole that formed in another, much larger, universe.

The theory challenges many fundamental models of the cosmos, including the idea that the Big Bang was the beginning of the universe.

It also provides the possibility that black holes within our own universe may be the boundaries to other universes, opening up a potential scenario for a multiverse.

Last few paragraphs...

Shamir noted that an alternative explanation for why most of the galaxies in the study rotate clockwise is that the Milky Wayโ€™s rotational velocity is having an impact on the measurements.

โ€œIf that is indeed the case, we will need to re-calibrate our distance measurements for the deep universe,โ€ said Shamir.

"The re-calibration of distance measurements can also explain several other unsolved questions in cosmology such as the differences in the expansion rates of the universe and the large galaxies that according to the existing distance measurements are expected to be older than the universe itself.โ€

That's leading me to think that that's actually the more probable explanation, and the black hole idea comes in a distant second in terms of probability, but is much more attention grabbing/sensational/click-baity.
