The Hidden Rules of Reality
Like Duolingo, but for The Hidden Rules of Reality. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
For the part of you with thirty open tabs that never became anything.
A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through Breaking Your Intuition and The Very Small and the Very Large. It starts from scratch.

Key ideas in The Hidden Rules of Reality
- Massive objects warp the fabric of space-time around them
- Objects respond to the shape of the space they are in rather than a 'pulling' force
- The trampoline analogy: mass creates a dip that nearby objects roll into
- The fundamental nature of gravity as geometry rather than a force
- Objects in motion follow the shortest, straightest path possible (geodesics)
- A 'straight' path in curved space naturally results in a circular or elliptical orbit
- Orbits require no active steering because the 'track' of space itself is curved
- Understanding that orbits are straight-line paths in curved space
- Light follows geometric curves
- Gravity as geometry
- Gravitational lensing
- Warped space confirmation
- Orbits as geodesics
- Black hole density
- Infinite curvature
- Light as speed limit
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives The Hidden Rules of Reality the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
