Astronomy — orbits, distances, and the cosmos
astro
Orbits obey Kepler and Newton; distances climb the ladder (parallax, standard candles); the cosmos is governed by general relativity. The orbital arithmetic is already sealed on the astronomy stick; this floor places it, resting on relativity (gravity as geometry, cosmology), Maxwell (starlight and spectroscopy) and the instruments (the measurement). No new stick (tools/seed_astronomy.py).
