Relativity and astrophysics from special relativity through cosmology. Covers Einstein's postulates, time dilation, length contraction, Lorentz transformations, relativistic momentum and energy (E=mc^2), spacetime diagrams, the equivalence principle, curved spacetime (conceptual), gravitational lensing, black holes (Schwarzschild solution, Chandrasekhar limit), stellar evolution (main sequence through supernova), and cosmology (Big Bang, Hubble's law, CMB, dark matter, dark energy, FLRW metric)…

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'relativity-astrophysics' ] || [ -L ~/.agents/skills/'relativity-astrophysics' ]; then echo 'A skill folder named relativity-astrophysics already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/Tibsfox/gsd-skill-creator' "$d" && git -C "$d" checkout --quiet 'e179dfe911f3b3c2ff8bcd90ecd6ee4738648d17' -- 'examples/skills/physics/relativity-astrophysics' && mkdir -p ~/.agents/skills && cp -R "$d"/'examples/skills/physics/relativity-astrophysics' ~/.agents/skills/'relativity-astrophysics' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'relativity-astrophysics' ~/.claude/skills/'relativity-astrophysics' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
