Where Physics Breaks
Like Duolingo, but for Where Physics Breaks. 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: 9 levels across 2 sections, about 18 minutes end to end, roughly 4 days at five minutes a day. It moves through The Quantum Fabric and The Gravity Trap. It assumes you already know the basics.

Key ideas in Where Physics Breaks
- Particles exist as wavefunctions of probability until an interaction occurs
- Protons in stars are positively charged and naturally repel each other
- Measurement or collision with a detector forces a definite state
- Stellar heat alone doesn't provide enough kinetic energy to overcome the Coulomb barrier
- The 'collapse' is triggered by the particle interacting with its environment
- Tunneling allows protons to 'teleport' across the barrier to ignite fusion
- The transition from probability to defined state in cosmic interactions
- The role of quantum tunneling in stellar nucleosynthesis
- Entanglement creates a single quantum system regardless of physical distance
- Information appears to transcend the speed of light through non-local connections
- The universe's underlying fabric is interconnected in ways that bypass 3D space
- The Uncertainty Principle creates a fundamental limit on measuring paired variables
- Increasing precision in position measurement makes momentum (speed) more erratic
- This 'fuzziness' is a property of the universe, not a flaw in our telescopes
- Vacuum energy consists of virtual particles constantly appearing and annihilating
- The implications of non-locality through entanglement
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 Where Physics Breaks 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.
Here's what playing it feels like
