    Kurzgesagt – In a Nutshell

    6 חודשים לפני

    We created our first app ‘Universe in a Nutshell’, together with Tim Urban of Wait but Why! You can get it here: Appstore: Google Playstore: Oh boy. Making an app is hard. It seemed so easy when we started. We underestimated the necessary work load and all the potential problems tenfold - this is not a figure of speech, this took ten times longer than we thought it would. And we are sort of used to working on big projects. So the first update to the app should hopefully be here in the next 24 hours (we are waiting for approval of the update in the app stores) - it will fix a bunch of small things that slipped through. We’ll constantly improve this thing because while it was honestly a horrible nightmare to make, it also was fun and we want to get better at it and make more things in the future. In case you don’t know Wait but Why btw, it is the best and most fun blog on the internet ( and if you don’t know it you should change that like right now. Tim and I collaborated for the first time in 2013 and we have been good friends ever since. And this thing was something we started talking about years ago. So what is this thing we made and why? You can seamlessly travel from the smallest things in existence, past the coronavirus, human cells and dinosaurs all the way to the largest stars and galaxies and marvel at the whole observable universe. You can learn more about each object or simply enjoy the sheer scale of it all. It’s a fun plaything. The app is inspired by the “scale of the universe” website by the Huang Twins that Tim and I spent a lot of time with when it came out years ago - and felt that it was finally time to create a Wait but Why and Kurzgesagt version. There are no in-app purchases and no ads. All future updates are included! Since this is our first app we would love to hear your feedback so we can improve it over time. Leave us a five star review if you want to support it. Kurzgesagt and all the projects we do are mostly funded by viewers like you. So if you like the app we’ll make more digital things in future! Ok! Thank you for reading - Philipp

    11 times larger than earth? No, it's diameter is 11 times larger. You could fit approximately 1300 Earths inside Jupiter. Edit: Senior Scientist and Senior Educator Jackie Faherty recently said could get fusion inside the core of a "planet" (wouldn't really be a planet anymore), if you had around 13 Jupiters. 90 would be plenty to create fusion. Check your facts.
