  • Time doesn’t slow down when you approach the speed of light

    Correct, but only from your perspective. To other people you’ve slowed down, but from where you’re sitting (or careening through the cosmos at the universal speed limit) everything happens just as fast as it normally does.

    the theory we’re using to describe much of the universe is based on a bad premise, that the speed of light is constant.

    Quasi-correct. “The speed of light” as we think of it in physics is actually the speed of information, which dictates how quickly changes can propagate outwards (or put another way: how quickly you can know about something happening elsewhere). We refer to it as the speed of light because photons move at that speed in a vacuum due to having no mass and thus moving at the fastest possible speed, but things like gravitational waves also propagate at that same speed and have nothing to do with EM radiation. However, the speed of information doesn’t change; it’s a hard natural law with no known exceptions.

    Physics in general is cheating for this thread though, because the answer to what makes stuff happen as we understand it is a giant metaphorical mass of “I 'unno.” The Standard Model, relativity, quantum mechanics, string theory, etc all have giant gaping holes in them that other models can often fill, but cannot be properly combined in any way that we’ve tried so far. They’re still correct enough to base your entire life around without any worries, but there’s always that last 0.01% that amounts to the margins of old maps reading “Here There Be Dragons”.










  • Games have to talk to your operating system to have it tell your GPU to draw lots of funny pictures that come together to make up the graphical portions of the game. Game developers do not want to do this directly, because talking directly to the OS is hard. As such, games talk to graphical APIs like Vulkan or DirectX to do the hard bit for them.

    For years almost all games used DirectX, which is made by Microsoft. This gave Windows a virtual monopoly on PC gaming because they weren’t about to let their competitors use their API. Then Vulkan came out, which was designed from the beginning to be OS-agnostic, sending us to the promised land of games that could (with some other efforts) run on any machine, anywhere.


  • Feudalism never ended, it just transitioned from a bunch of failsons inheriting land titles to a bunch of failsons getting middle management jobs through nepotism. Every company larger than 50 people is a vast internal labyrinth of lords-in-everything-but-name jockeying for promotions, accolades, and raises by inflating their roles, and the best thing you can do for yourself is find a position that isolates you as hard as possible from having to deal with that yourself lest you end up spending 50 hours a week working to get one over some petty rival of your boss.
