    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

    Most of what this video drones on about is flat earth science. A star is not a nuclear fusion reactor. That is not how it creates energy. The paradigm has shifted. The Electric Universe Model is the new paradigm. No big bang, no dark matter, no dark energy, no black holes, this folks is flat earth science pushed by a cult of insane scientists that have veered so far from reality that none of it no longer makes sense except in fantasy land.

      You know that eletric universe is absolutely confirmed to be a wrong model as well a flat earth. Look with our "gravitional universe" we explain nearly everything correctly, but you say that in fact all is due to electricity but that doesn't make sense because if it was true we already would have found out. I'm suggesting you to watch the electrical universe video by "professor Dave explain"

      For our sun model tends to say that it will grow a lot, like having the size of the orbit of earth and becoming a red giant. And then shrink again and becoming a white dwarf and then cooling for ever with radiation and becoming a black dwarf at the end.
