I built this because measuring my age in years felt boring—I wanted to see the kilometers. The first version only used Earth's orbital speed (~30km/s), but the number moved too slowly. To get the "existential dread" feeling, I switched to using the Milky Way's velocity relative to the CMB (~600km/s). The math takes some liberties (using scalar sum instead of vector) to make the speed feel "fast," but it gets the point across. Under the hood, it's a single HTML file with zero dependencies. No React, no build step. The main challenge was the canvas starfield—I had to pre-allocate the…

A little while ago I built a tool to calculate how far you've traveled through space since the exact second you were born. The math was relatively simple (Earth's spin + Solar orbit + Galactic drift), but the feedback I got here inspired me to rewrite the visual engine and turn it into a proper deep-space dashboard. Here is what’s new under the hood: 1. Vanilla JS 3D Engine: I built a custom Three.js simulation that renders your exact orbital alignment on your birth date and tracks it to the present. 2. Live Telemetry: It now actively tracks the real-time Keplerian orbital positions of…
