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.

What you'll learn

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
