Every tap on the screen expands the universe, and the camera pulls endlessly back. Start from a tiny point at the Planck length (10⁻³⁵ m) and pass quarks, atoms, cells, people, Earth, the Solar System, and the Milky Way — all the way to “Infinity” beyond the observable universe.
Stages you've passed shrink into the center at their true relative scale, while the next one drifts in slowly from off-screen.
Hand-drawn art for every stage, ripple and debris effects where you tap, and combo effects — zooming out from the Planck length to “Infinity”.
3 tap upgrades + 5 auto-expansion devices. x2 at every Lv.25 · 50 · 100 · 200 · 400 milestone, with a hint for the best upgrade to buy now.
Restart the universe to earn Singularities for a permanent multiplier, then research cosmic constants like the idle cap, combo cap, and starting energy.
The universe keeps growing while the app is closed; check the settlement screen when you return. A notification when the idle cap fills is optional.
A real astronomy fact card unlocks at each stage (21 in all). Real-size comparisons with the Eiffel Tower, the Moon's orbit, and galaxies, plus advanced cards and a 21-question quiz.
17 achievements, stage-reach times compared with past runs, Big Bang history graphs, and detailed stats like total taps and play time.
Each stage you reach unlocks a real astronomy fact card, and you can compare how big your universe is right now against the Eiffel Tower, the Moon's orbit, and galaxies.
Astronomical figures in the game are approximations for fun and learning.
