Cosmic Odometer
Calculate your distance traveled through the universe
What it does
We feel like we are sitting still, but physics says otherwise. Cosmic Odometer is a visualization tool that calculates exactly how far you have physically traveled through the void since the moment you were born. four velocity : Earth's Rotation Solar Orbit Solar System Velocity Galactic Drift New in Version 2.0: The Cosmic Receipt: Generate a retro sci-fi "Flight Log" image with your stats to share on social. Vanilla JS: Built with zero dependencies, runs entirely in your browser.

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…
