The Fabric of the Cosmos
Like Duolingo, but for The Fabric of the Cosmos. 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.

Key ideas in The Fabric of the Cosmos
- Space and time are a single 'spacetime' fabric where events are coordinates
- Massive objects like stars create a 'well' in the geometry of spacetime
- Disturbances in spacetime travel as waves at a finite speed
- Objects follow the straightest possible path through this warped geometry
- An event in space is simultaneously an event in time within the fabric
- Gravity is a consequence of shape rather than a traditional magnetic-like pull
- Information about gravitational changes travels at the speed of light (c)
- Objects in motion follow 'geodesics', the shortest paths in curved space
- The relationship between space and time as a single fabric
- Nothing, including physical 'news' of an event, can outrun light
- Gravity as the path of least resistance (geodesic)
- Mass curves geometry rather than exerting a 'pulling' force
- The speed of light as a limit for information transfer
- Stronger gravity (closer to mass) slows the passage of time
- Time dilation occurs because gravity stretches the intervals between moments
- GPS satellites must account for faster-ticking clocks in weaker gravity
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 Fabric of the Cosmos 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
A real question from this course. Take your best guess.
What happens to the geometry of spacetime when a massive object like a star is placed within it?
