  • Sorry I should have clarified: not looking for Hexbear lore in general. I have seen a lot of Hexbear content, so I have a solid understanding on the site and the users. Don’t want to start a debate about that here because that debate always turn nasty.

    What I am looking for is: what happened in the past month-ish? How did you all lost your domain? How and when did you get it back? Why did it take so long for federation to be back? Is there any other change made to the site during this downtime?



  • I recommend critically reading the paper. It is quite accessible to those with college-level science background.

    Most importantly, it is still highly controversial whether this galaxy rotation direction bias actually exists. If you look at section 4 of the paper, the author is debating against different groups that did similar surveys and found no bias. Someone needs to actually work through this author’s methodology as well as those of other groups and figure out what is going on.

    If there is indeed a bias, that is super exciting! An anisotropic universe due to being in a black hole would be a very cool explanation. But given the ongoing debate, a general-audience publication like Independent presenting this rotation bias as a given fact is very poor journalism.

    As stupid as that sounds, you are not totally wrong.

    @don@lemm.ee and @kopasz7@sh.itjust.works you are misunderstanding what “observable universe” means. The observable universe is defined by the particle horizon, but the universe that can affect us in the future is defined by the event horizon. https://en.wikipedia.org/wiki/Cosmological_horizon says

    The particle horizon differs from the cosmic event horizon, in that the particle horizon represents the largest comoving distance from which light could have reached the observer by a specific time, while the cosmic event horizon is the largest comoving distance from which light emitted now can ever reach the observer in the future.

    But even the cosmological event horizon distance is dependent on our model of the universe’s expansion, which in turn depends on the content of the universe. An event such as a vacuum collapse will drastically alter the content and the expansion rate, rendering our calculation of the event horizon invalid. So “snap changes…” may in fact be the case.
