Infinite Universe: Space Idle

Infinite Universe — the more you tap, the bigger it gets

Every tap expands the universe, and the camera keeps pulling back. Start as a tiny dot the size of the Planck length (10⁻³⁵ m), then grow past quarks, atoms, cells, people, the Earth, the Solar System and the Milky Way, all the way beyond the observable universe to Infinity. Each stage you leave behind shrinks into the center at its true scale, while the next one drifts in from off-screen.
