Key ideas in The Universe Above Us
- Artificial light creates a 'sky glow' that outshines faint stars
- Constellations are 'connect-the-dots' patterns created by our specific viewpoint in the galaxy
- Stars are always present in the sky regardless of local lighting conditions
- Stars in a constellation are at vastly different distances from Earth
- Understanding that light pollution masks rather than removes stars
- Recognizing that constellations are perspective-based patterns, not physical groups
- Polaris sits directly above Earth's axis of rotation
- Your hand held at arm's length covers a consistent amount of the sky
- The rotation of the Earth makes the rest of the sky appear to spin around a single point
- Specific hand shapes correspond to degree measurements used on star maps
- The eyes require about 20 minutes to chemically adjust to low light
- Looking at a bright phone screen or flashlight resets this 'timer'
- Applying the rule of dark adaptation for stargazing
- The Moon is a rocky body with no light-producing fusion
- Moonlight is actually sunlight bouncing off the lunar surface
- The Moon's source of illumination

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 Universe Above Us 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
