Universe in a Nutshell

Wait But Why & Kurzgesagt

About this app

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 galaxies 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, how it works, and our favorite mind-blowing facts

Beautifully animated illustrations of more than 250 objects

Original Kurzgesagt music to complement your experience

Ratings and reviews

Very interesting app. Lots to learn. I'd recommend adding some sort of comparison feature where you can select 2 or more items and have them specifically compared to one another. For example, It would be cool to see mt. everest on the same plane with central park... Or an oxygen molecule next to the coronavirus... Ya know, for no particular reason...

This kind of website/app has always been enjoyable for me but Kurzgesagt's style adds a nice new layer to the experience. The music was also very unexpected and very pleasant, helping to create this whimsical mood as you swipe through these immensely large/small distances. Good sense of humor here too. My major gripe is that I am unable to reorient my screen while using this app, which is pretty dumb. This is really minor though and doesn't detract from how worthwhile this whole thing is.

Exactly what it says on the tin- amazing visuals bu Kurzesagt (I probably butchered the spelling, sorry.) along with educational content. One star has been deducted due to a bug that makes you unable to zoom out if you reach plank length, and unable to zoom in if you reach the observable universe. Other than that, it is a bit overpriced but I can look over that since it is going to a group I support.
