I built a true-scale atlas of the universe (8.4M real stars) in about a week with Fable

When I got access to Fable, I wanted to test it on something ridiculous. Why not the universe itself? The result is an atlas that renders everything at its measured size, distance, and speed, one continuous zoom from the cosmic web down to quarks: real Gaia DR3 stars with proper motions, 2.6M SDSS galaxies at their true distances, planets on real orbits, live satellites, and the Aug 12 total eclipse crossing Iceland within about ten minutes of the true time. You can fly anywhere with mouse, keyboard, or touch, or press T for the guided tour. **Setup and numbers** * Claude Code with Fable 5 on Max(5x) plan * A bit over a week: 92 merged PRs, 237 commits,…
