    Stephenson 2-18 sounds like a Bible verse, lol. I was promptly disappointed to find out there is no Stephenson chapter

    They say God created all this. I fail to be convinced.

    It’s crazy in a billion years we will all be turned into ash and the world as we no it is going to perish and all of our loved ones……..

    "So even if we took 90 Jupiters and threw them at each other, although fun to watch, it wouldn’t create a star."

    So important that we believe ourselves and are nothing, did someone else feel like an Ant on the scale of the universe? Think of the millions of forms of life Giant or smaller than us (which I do not believe, because our planet is tiny in itself)

  22. Homa Simpson on October 1, 2020 at 3:22 pm

    God has really big hands to make planets , and he wears gloves because obviously they are hot , he gets them from the hardware store next to the universe , he keeps the universe in a box next to his bed

  23. Arthur Salak on October 1, 2020 at 3:24 pm

    we are small little particles in this universe, we don’t actually matter that much as we think we do 🙂
    Greater things are out there.

  24. THE SEARCHER on October 1, 2020 at 3:27 pm

    What about UY SCUTI 🤔

  25. Rusca8 on October 1, 2020 at 3:32 pm

  28. Kurzgesagt – In a Nutshell on October 1, 2020 at 3:36 pm

    We created our first app ‘Universe in a Nutshell’, together with Tim Urban of Wait but Why! You can get it here:
    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

    But are starships meant to fly? Asking for a friend.

  30. iam june on October 1, 2020 at 3:37 pm

    the background music of this video was by far the most beautiful

  31. Jinwoo Ahn on October 1, 2020 at 3:38 pm

    Big fake stars CG explanation for many many years without any proof since I was a kid.

  32. Jacek Piotrowicz on October 1, 2020 at 3:39 pm

    I… I… I don’t understand… I thought sun was big. Buhuuuhuuu.
    Now I’m shocked.

  33. Wed Alsallom on October 1, 2020 at 3:39 pm

    Are stars alive? The same way humans trees and animals are alive? How can something be born, grow and die if it isnt alive?

  34. Faiz ullah shah on October 1, 2020 at 3:40 pm

    And what about the sun, is the sun static or moving in the universe?

  35. Neil gelinas on October 1, 2020 at 3:42 pm

    Is it Betleguise?

  36. NiX aKi on October 1, 2020 at 3:42 pm

    Shouldn’t it be called hypernova?

  37. Thomas Estrémé on October 1, 2020 at 3:43 pm

    Hey guys, I love this channel and all, and in that spirit I’d like to point out I felt kinda uncomfortable with the bully talk bit about the brown star. I mean.. It’s bad in real life, not funny. It should never be funny. Some people lost themselves over these communicative habits.

    That sided your work is truly incredible and I look forward to watching more of your content !

  38. Dragonmoth on October 1, 2020 at 3:45 pm

    1:51 Stars like the Sun are growing all the time, it’s just very very slow. In the last 4 billion years the Sun has grown about 20%.

  39. tomt iedom on October 1, 2020 at 3:45 pm

    Excellent music

  40. Nagendra Gupta on October 1, 2020 at 3:46 pm

    Please correct the title to – Largest star known to humans

  41. Wisgarus on October 1, 2020 at 3:49 pm

    Isn’t it amazing how a species that was one just a kind of primate or such trying to stick a rock to a stick now knows how muffin stars work? Sure we don’t know everything about them, but you gotta admit that it’s truly fascinating how far we’ve come

  42. Kumar Harsh on October 1, 2020 at 3:50 pm

    Awesome stuff, and Congratulations for the app with Tim. You guys are among my top 5 favourite content creators <3

    absolutely LOVE kurzgesagt, I will become be part of the kurzgesagt family once i am financially able to

  45. Old Seadog on October 1, 2020 at 3:52 pm

    Those stars that shed billions of tonnes per second probably got threatened by Chuck Norris.

  46. John Juan on October 1, 2020 at 3:53 pm

    Commentator isn’t the same guy that did the commentary for "The Hitchhikers Guide to the Galaxy" is he? Because he sounds just like him 😀

  47. Ching Ching on October 1, 2020 at 3:55 pm

    We have detected a bigger star. An Orange Hypergiant: DJTrump45

    This is the best collection of fiction I have seen in a long time. We don’t even know about the earth but we know all this information about lights in the skies 😂 good one

  50. Rory Mag on October 1, 2020 at 3:56 pm

    That ending was epic
