  • There is the analogy of a balloon’s surface where every point moves away from its neighbor, or a better analogy of bread expanding as it is baked, since that’s more three dimensions. The idea is that space is expanding at the atomic level at a certain rate, but it’s so small that it takes an astronomical amount of these atomic increases to be able to measure it (we can’t measure expansion at solar system scales, or even between our galaxy’s stars, as gravity drowns out the effect. But space is so large that over distances like between galaxies, the light that has traveled all that way has had to travel over this expanding so much that we can see a shift in its wavelength. And overall everything is shifting red, so either we in our section of the galaxy are the center, or it’s something that’s common in any part of our universe. One of these is far more likely.


  • Reddit had simply changed for the worse after ten or so years. Some of the niche subreddits I was in were still okay and not touched by the issues (yet), but I felt that it was for the best to move to other places. The Reddit migration popularized the Fediverse idea (that had been there already), and it made sense to me to decentralize discussions to resist control. For the most part the past few years this has felt more or less like old Reddit, and even previous forums before I found Reddit, because in the end discussion areas are made up of the people posting in them, not the architecture they’re on. It’s the transitions between that are the hardest.


  • My mother’s car, a 1981 or so Dodge Aries K-car. I guess those who went to a driving school got their license from there as well? Back then we just got a short course in high school, drove a few times with the instructor, and then had to go to the DMV with our own car to do the actual test.

    It took two times. The first time I had trouble starting the car (because it was a Dodge/Chrysler POS) so that instructor denied me after the third try at cranking it. Of course it rattled 17 year old me. Second time (different place, different instructor) went a lot smoother, only issue was my slamming on brakes for a red light, but that probably helped me rather than running it.

    I don’t think we’re sure what makes it and what doesn’t. Some of the first radio broadcasts were very strong and maybe even directed more, but over time due to competition limits were put on transmission power. Then there’s the question of general direction vs. a directed beam which would have more distance before it gets lost. Lastly, lower bandwidths were used as technology modernized, which would hide more in the background.

    But even if the strongest part gets to a planet and lasts for years, what if their time to invent and use radio is still far in the future, or gone in the past and they don’t even look in those frequencies. It could be more a matter of timing than anything else.

    I still wait for the darkly humorous joke until it really happens message to us, “Shhhh, they’ll hear you.”
