About Universe in a Nutshell

The range of size in the universe, from the tiniest particles to the epic galaxies - we take you on a journey of size that lets you explore it all with a single swipe. How big is a planet, compared to a human? And how small is an atom really? You can’t fully wrap your head around the scope of things by just reading about them – so this app lets you experience them in comparison to get a feeling for their true scale. By simply swiping you can zoom in and out all the way from the world of fundamental particles up to the largest stars at the edge of the observable universe. Seamless zooming between the scales of 10^-35 meters to 10^26 meters (no math required) Amazing fun facts for various scale levels, like the smallest bacterium and the largest black hole Tap any object for an explanation of what it is and how it works Beautifully animated illustration of more than 250 objects Original Kurzgesagt music to complement your experience
