  something is ~weird~

  The video is nice, particularly the mid-video, but it feels a lot like an early aviation movie reel of a dogfight in the sky. its wont shine without a reference point, and that's hard to do in space.

    That video made sense. Using the information from a prior graphic showing that the entire map is made from the perspective of the earth, the video then places that data in one of the arms of the theoretical Milky Way where the earth is meant to be located, and clearly shows a lack of data in the direction of the center of the Milky Way. That tracks with anything I'd imagine the results to look like

  Is this anything but a really long winded way of saying that they got a better fit from their model by adding more parameters? That’s not news…
  • somenameforme 2y ago
    Yes, but said model contradicts the typical understanding of dark energy. So I think the takeaway is not that 'this new model is how the universe works', but rather that 'our typical understanding of dark energy is inconsistent with what we are observing.'

      Maybe also a good time to revise the Axis of Evil: https://en.m.wikipedia.org/wiki/Axis_of_evil_(cosmology) https://en.m.wikipedia.org/wiki/Axis_of_evil_(cosmology)

        Huh - if all you read was Wiki’s content “above the fold”, it would seem pretty conclusively debunked. But once you expand the actual evidence it’s far more mixed. There does not appear to be any consensus at all.
        • gitaarik 2y ago
          Yeah, in almost all observations / readings the axis is there. There's just no explanation for it, and most people shrug it off as a data inconsistency or error with the measurement. But this measurement / data is the same that we base the big bang theory upon. The CMB is actually the biggest proof for the big bang theory. And the axis of evil is starring us right in the eye. That's why they call it like that, it's an unexplainable evil anomaly that challenges the scientific worldview. And that is also why scientists generally don't look at it or even want to talk about it. Because as a scientists you can't do much with it except being confused and weirded out. I'm very curious if there will be new discoveries or theories that would explain it.
          • fashion-at-cost 2y ago
            Reading into it a bit more, it seems like essentially the idea is you can take a sort of 2D Fourier Transform of the CMB, and the 4th and 8th terms of this series are generally aligned with the solar system’s axis. It’s interesting, but not quite a slam dunk unless I’m missing something – across all the terms in the series, some of them would be sure to generally align with our axis right?

  So if the new data is correct, there's no heat death or big rip, no? Everything just crashes back into itself.
