  • Correct, the differences make the analogy good enough to visualize the concept. It does however suffer from the same problem as the balloon one, in which someone can get the impression the expansion has a center. The wiki for the expansion of the universe goes through the various analogies and where they break down.

    I would suggest Dr Becky’s Youtube channel for a number of excellent videos on the expansion as well as the current problem of getting an accurate measurement of the correct Hubble expansion rate. The James Webb telescope was hoped to solve that dilemma, but we still aren’t sure.



  • At the cluster level it will depend on the velocities and distances. For example, using very rough numbers the current expansion rate means that space between us and the Andromeda galaxy is expanding at 55 km/s. Seems fast until you realize the distance needed to see the effect build to this level. For perspective I found someone’s calculation to reduce it to solar system level to end up with ~10 meters/AU/year. But of course at this distance gravity dominates so we can’t measure that directly and it may not even be large enough to consider.

    A larger and slower moving galactic cluster would be more affected than a tighter one. I don’t know what our Local Group would be considered to be, but there are a hundred or so galaxies around us that appear blue shifted, so they are moving towards us even with the expansion.

    Good visualization but inaccurate. Space between galaxies in a cluster and even the stars in a galaxy is also growing. The difference is in scale. There’s so much distance between galactic clusters and the largest structures of the universe that added up that expansion amount is so much bigger. The balloon analogy with galaxies as dots on the surface is closer since the dots also do grow some, but the balloon would have to be huge to capture a good scale comparison.


  • Even a hypothetically true artificial general intelligence would still not be a moral agent

    That’s a deep rabbit hole that can’t be stated as a known fact. It’s absolutely true right now with LLMs, but at some point the line could be crossed. If and when, how, and by what definition has been a long debate nowhere near resolved.

    It’s highly possible that AGI/ASI could come about and be both super intelligent and self conscious and still have no sense of morality. But how can we at human levels even comprehend what’s possible? There’s the real danger, we have no idea what we could be heading towards.


  • That was the next layer, but they can’t get to that point if the voting isn’t close. I don’t disagree that elections is one of the many reasons why the court got stacked, but way before the SC there WILL be corruption attempts at the voting level. See Steve Bannon’s commentary on how they’ve put people in place in voting areas and have formulated a plan to question voter authenticity. They know they can’t win with a fair election, so they’re finding more and more ways to subtly cheat. Or maybe not even subtle now, since they keep saying everything out loud.

    And the best way to counter this is drown the attempt in voter numbers, so that even if ballots are questioned or tossed or people turned away, the number still are high.




  • I don’t think that’s the problem. Here’s an example of the distribution of voting, and it’s sort of what you’d expect from the stereotype. Note that Gen-X is close to 50%, a bit more to the right. What affects things more (and mentioned in the article) is actual voting, or rather the lack of voting from the apathetic or oppressed or mislead. If more younger voters don’t vote, the results skew to the right.

    Add to that how different the commitment to party is between left and right. Left has lots of differing opinions and the infighting between Democrat and farther left 3rd party voters often result in either spoiler or no votes at all (which is why ranked voting would be a huge change). Right on the other hand, we’ve all heard the line about party first, no matter what. Liars, rapists, felons, still voting for the candidate because that’s what a Republican does.

    I don’t know if the latter can be easily fixed outside of better education both in voting information and in general. The right really aren’t in favor of any of that though, that would hurt their numbers. Trump even said it out loud, they love the poorly educated.

    The first part though is powerful. I’ve heard it said to young crowds many times that if more of them show up they can hugely affect the results.

    I’m not denying my generation (Gen-X, and why I felt I needed to reply) has its share of MAGAs. Long ago when I first joined Facebook and started adding friends I found from high school I thought it would be cool to reconnect. It was disappointing how quickly I found so many of them were not the same left-leaning radical free thinking people I thought I knew back then. But MAGA mania isn’t solely in one generation, it’s a problem shared that will stay around if we don’t change some things.
