The Cosmic Web: Mapping the Universe
Like Duolingo, but for The Cosmic Web: Mapping the Universe. 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 Cosmic Web: Mapping the Universe
- Galaxies are not scattered randomly but are clustered together
- Gravity pulls gas and dark matter together to form the first structures
- Most of the universe consists of vast, empty spaces called voids
- The universe is organized into a specific structural network rather than being evenly distributed.
- The expansion of the universe fights against gravity, but gravity wins in local pockets to create filaments
- Matter is concentrated into long, thin strands and dense knots
- Large-scale structure is the result of small density ripples being amplified by gravitational attraction
- Gravity is the force responsible for pulling matter into the large-scale structures we observe.
- Light takes time to travel across the vast distances of the universe
- Seeing distant objects allows us to see the universe as it looked when it was much younger
- The 'lookback time' increases the further we peer into deep space
- Filaments act as the 'highways' connecting dense regions
- Nodes are the brightest and most crowded points in the structure
- The Cosmic Web is the largest identifiable pattern in existence
- Identifying the components and scale of the Cosmic Web.
- On a small scale the universe is 'lumpy' (planets, stars), but on the largest scale it is uniform
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 Cosmic Web: Mapping the Universe 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.
