Black hole cosmology suggests our entire universe formed inside a black hole from another universe

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.

    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.

      Thanks for breaking that down, I wish newspapers or even BBC News did this. They do now have BBC Verify but its never super clear of their findings, certainly not in the format that you’ve just used. Perhaps theirs should be called BBC Balance. The only thing I would say with regard to your first point is that I’m not against the idea that any individual could make a breakthrough. At least with regard to theory.

      We already know that throughout the history of cosmology, whole experts have been wrong when a new discovery is made. E.g. Highly likely that not everyone believed that Earth was centre of the Universe (like the earlier science communities claimed). The issue with this guy is he’s using his own biased ideas and data and some people believe whatever is printed in a newspaper must be right.

      Only silver lining is at least there clickbaity headlines give the public something more substantial to think about for 60 seconds instead of what the next Kardashian is up to…

        To be sure, I agree with your interpretation of your first point. I was establishing that as part of a pattern rather than an end-all “you can’t do science without a degree in that field”, especially since applied CS is monumentally important to every field. It’s that lack of formal education in cosmology combined with a pattern of only citing oneself for support of one’s arguments combined with this being a long-held and broadly successful assumption combined with numerous cosmologists using a variety of methodologies which they think are acceptable combined with no cosmologists choosing to use his algorithm combined with ostensibly using his time with The Independent talking almost exclusively about deep cosmological implications.*

        * This last one could be The Independent’s fault; it’s technically possible Shamir talked their ear off about CS stuff and methodology and previous attempts and what he wants to do going forward but The Independent only ran with the juicy sfuff.
