  • 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

  • Here's an interesting thought for you: Theoretically a star could be so far away from us that its light takes longer to reach us than the star is actually aLive. This means we know the star existed long after it died, and will see it alive even longer when its actually dead already.

    Jakob MertensJakob MertensPred 23 urami
    • @Kim K Well I called it theoretically because a star so far away that it light never reaches us while its still alive is also so far away that I dont think we can even see it,

      Jakob MertensJakob MertensPred uro
    • Yea these are called ghost stars I think. Same as how it takes 7 minutes for the light from the sun to reach us.

      RehaanRehaanPred 2 urami
    • I wouldn’t call it so much “theoretically” since we all know this fact. The light takes a while to reach us since the speed of light only is 299 792 458 m/s and the biggest star is 2,85e12 (2 850 000 000 000) m away from us so that leaves us with 9 506 seconds (6,6 days) that it would take us to relize that the biggest star is dead. [This was fun to calculate]

  • There should be something comparing a human to earth at the beginning, to give us a scale on just how small we are.

  • What's so sad is all these suns are dead 😥 by the time their light reaches us RIP. There is a super massive star (known as the great attractor), it is hidden from use because our galaxy is blocking our view, plus because of dark matter lence effect.

  • Why are you telling all this as a matter of fact? None of this regulation is proven. The dogmatic science you're so brilliantly narrating is unfortunately, for you and science, absolutely wrong. There is little to nothing you are correct about. Dear me. Move on from this settled science nonsense and start at the beginning of physics,, Berkland, Tesla, Pratt. They are on the right track. SAFIRE PROJECT are proving and repeating, reproducing and solving the biggest issues with physics and cosmology. Without the need for adhock holes, dark this n that. Just simple scalable science

  • What a shame that we humans are still insinuating that there is no G-d (Creator) of this amazing Universe, where if we were to scale ourselves with these Hyper-giants we would be nothing but a tiny nano dot (quarks) as compared to what G-d has created out there in the universe. And in the past, our ancestors had the audacity to call upon mere human beings like us as God of this universe. And people in modern day and age still calling upon those mere human beings as their Personal G-d. Personality like Barhama, Ram, Krishna, Buddha, Jesus or in cosmos these mere Stars / Planets had became their personal G-d. How dumb and foolish that seems and sounds. What a shame. Thanks to Almighty Lord/Master of this universe that He guided me and made me a believer in Him alone. I wish and pray then my every fellow human-beings could able to see this light whenever they observe this beautiful creation that Our Creator has created for us to ponder and reflect deep so that we come back to Him alone in full submission - amen

Sci-fi book about Jupiter ignition into a sun which is then named Anubis?

  • Given that Stephenson 2-18 is about 2150 solar radii and the radius of the earth is about 6,378 kilometres, placing the sun on the surface of Stephenson 2-18 is like placing a sphere with a 3 kilometre radius on the surface of the earth, so compared to the largest star in the universe the sun is rather more impressive than a human compared to earth.
