The size range in the universe, from the smallest particles to epic galaxies, we take you on a size journey that lets you explore everything in one fell swoop.

By simply swiping, you can zoom in and out all the way from the world of fundamental particles to the largest galaxies at the edge of the observable universe.

Continuous zoom between scales from 10 ^ -35 meters to 10 ^ 26 meters (no calculation required)
