  • That’s pretty much how it is. In ancient times, planets would have been objects that were distinguishable from stars in ways they had the ability to differentiate from. For example, with a telescope, any object that doesn’t shine like a star, that moves across the sky at a different rate than the stars, or maybe has visible rings.

    Then once science found things that past science couldn’t account for, they redefined what a planet was, according to its size/gravitational pull or other factors, and which Pluto didn’t fit. Apparently due to Pluto’s small size, it’s not even a dwarf-planet, and by that measure is basically just a really big asteroid (we even know of asteroids that are bigger than Pluto).


  • Yeah this is the correct take. Either Pluto (and by extension, any object of similar size) is a planet, which would mean there’s thousands of Pluto-sized planets in the solar system; or pluto is ‘too small’ to be a planet. Which is the answer they (Sci community) settled on, because if every comet/asteroid is within the threshold definition of ‘planet’ then there would be no point in distinguishing planets at all.

    Kinda like how we have dwarf-stars and supermassive stars 1000x bigger than our sun. If they were all the same size there would be no point defining them beyond ‘star’.

    So why is it represented as 99.999… Instead of just 100? It’s because you’re forgetting the fact that fractions and decimals are infinite depending on the magnification. 99.9999… literally goes on forever. That means that no matter how close it gets to 100, it will never be equivalent to 100.

    It’s like how you can know infinitely nothing and still think you know everything. 👀🫠

    It only signifies that the post-decimal nines are repeating infinitely. It still doesn’t make 99.99999…=100 unless you intentionally round the value for some nondescript reason, and even then, rounding off isn’t changing the value, only the perceived value for mathematical simplicity, not objective accuracy.











  • Satisfactory. It’s been in early access for a few years now, 2019 I think? At the beginning of this year (2024) they announced the next update would be the 1.0 release. I’ve been playing it on/off for years, especially recently with all the strides they’ve made in development.

    The game is like Factorio, but presented as an FPS. You get dropped onto a planet in a pod straight out of Halo: ODST by a space-future megacorp called Ficsit, with the goal of harvesting the planet’s resources for Ficsit off-planet divisions.

    I have almost 1500hrs in Satisfactory since I got it, there’s no shortage of gameplay. Coffee Stain (devs) have been posting videos regularly, updating the community on new/discontinued features, revamped recipes and production rates, and even just being silly as much as being helpful, to the point where Coffee Stain is my go-to example of good devteam-community interaction.

    Oh, and it also has a really good modding community, so if there’s anything that’s not in game, that you want in game, it’s probably already been made by one or two modders.
