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.

Using data from Nasa’s James Webb Space Telescope, researchers at Kansas State University in the US discovered that the majority of the galaxies were rotating in the same direction.

This goes against previous assumptions that our universe is isotropic, meaning there should be an equal number of galaxies rotating clockwise and anticlockwise.

β€œIt is not clear what causes this to happen, but there are two primary possible explanations,” said Lior Shamir, associate professor of computer science at Kansas State University.

β€œOne explanation is that the universe was born rotating. That explanation agrees with theories such as black hole cosmology, which postulates that the entire universe is the interior of a black hole.”

yeah it's just the most headline grabbing possibility

Dude, after reading the paper from start to finish, this whole thing seems off.

  • The guy's an associate professor of computer science and has no degree in cosmology, but he's talking about cosmological implications of these findings.
  • Every single paper cited supporting his argument was written by himself (in exactly one case, it was written by himself and a coauthor). In total, Shamir cites himself ~~106~~ 130 times.
  • Numerous other papers by numerous other authors (some mentioned by this paper in attempted rebuttals) using a variety of methodologies find this not to be the case.
  • It violates the cosmological principle used by major and highly successful models of the universe.
  • The way he performed this analysis was an algorithm which he wrote. When he cites papers that have used this algorithm, he only cites himself, indicating no other academic in the world has thought this algorithm is seriously useful for this application.
  • When speaking to The Independent (which is of really middling quality), instead of speaking about the data itself and how he arrived at it, he (again with no formal background in cosmology) starts talking about the most clickbaity possible implications of this data.

It's totally possible Shamir is right and that there really is a massive bias. That would be extremely cool. However, he's published numerous papers on this over the last decade yet still seems to be the only one who agrees with it. Which to me is highly unusual.
