Hey, Temix, ever wonder how the stars can be read as a code? I bet there's a pattern you can't resist.
Temix
Sure, but only if the stars come with a clear mapping; otherwise it’s just noise and a perfect excuse for me to sit back and stare.
Koldovska
Sounds like you need a guide to translate the cosmos—let me show you the map, and then you can decide if the noise is worth listening to.
Temix
Sure, but only if the map gives me a clean algorithm—otherwise I’ll just watch the patterns play out and decide if the noise is worth the effort.
Koldovska
Sure thing—here’s a quick, clean way to turn the sky into something useful. Pick a single star or planet that’s bright and easy to spot, call it your “anchor.” Then line up the other stars in that constellation in the order they appear from the anchor, giving each one a number (1, 2, 3…). Use those numbers as a substitution cipher: 1 = A, 2 = B, 3 = C, and so on. If the constellation has more than 26 stars, wrap around or drop the extras. Now you can write a message, replace each letter with its corresponding star number, and the pattern will hide in plain sight. It’s a simple algorithm that turns a clear map of the stars into a code you can work with.
Temix
Nice, but remember the anchor star’s brightness changes with time and position, so you’ll end up with a moving key unless you fix the observation window. In practice, you’ll be scrambling through a dozen “alphabet” lists for each night anyway—pretty efficient for a hobby, not for a secure message.
Koldovska
Maybe try fixing the window to the time when the anchor is at its highest point—say 10 pm on a clear night—and keep that date constant each year; then the key stays steady, and you get a simple cipher that’s easier to reuse. If you want extra security, rotate the alphabet after every message using the number of hours between your observation times. It keeps the code moving but still follows a pattern you can remember.
Temix
Your idea is neat in theory, but every 10 pm the sky shifts enough that your anchor star’s exact coordinates drift by a few arcminutes—enough to break a one-to-one cipher if you’re not accounting for parallax or precession. Still, locking the observation time gives you a repeatable key; just make sure to store the actual celestial coordinates, not just the visual name. If you rotate the alphabet each message it’ll look clever, but the underlying pattern remains trivial once someone cracks the first sequence. Good enough for hobbyist cryptograms, not for anything real.
