What is outside of the universe? We know that the universe had a beginning 14 billion years ago and that it has been expanding ever since.
But something that is expanding should also have an edge, right?
What would you see if you went there?

  • When Im feeling lonely, I look at the sky, pick a direction, and wave. Because if the universe is infinite, that means there’s another me also feeling lonely and waving back directly at me.
  • @betterchapter
    Every Kurzgesagt video: - Facts - Scares you - Then calms you down - Add birds
  • @huy4957
    The art direction here is so good, so much different scenes with varying styles and it doesnt ever feel boring or repetetive, it takes concepts and expands it, just like the universe. Neat fun fact while im here : Astronauts took their name from latin : "Astro" meaning stars and "nautical" meaning sailor, so the full name means "Star-Sailor" so maybe that's what influenced the visuals here ! its so neat and such a nice image and its executed so nicely, much love!
  • @karmanomicon
    I swear I've been talking about this exact stuff for years. This and your video on time. I talk and I talk and some people get it and some people think I'm crazy... and then you drop a brilliant animated explanation and I show it to those people and they have a lightbulb moment. I'm so glad someone out there is presenting these ideas with such high quality while also acknowledging the untestability of this science philosphy. 10/10
  • @cooldude702
    ah yes, another tuesday afternoon where i question my reality and the universe while watching a Kurzgesagt video, perfection.
  • @forgingluck
    "only boring stuff repeats itself" definitely a few million infinite copies of me in the infinite universe then
  • @notimmortal5938
    4:11 "Some scientists thought of this as way too straightforward, and came up with a wilder option." Why y'all gotta make life so difficult for us man???? 😭😭
  • @mylesmackey2430
    When I was 6, I asked my mom what the edge of space looked like but she just said “shut up with your nonsense”. I’ve waited so long for a proper answer
  • I remember reading something somewhere a long time ago: "When infinity gets involved, possibilities become certainties"
  • "This edge is more like an edgin time" Never thought I would hear kurzgesagt say edging time.
  • @TheWestychick
    When my kids were little , we were lying on the back lawn star-watching. I said the universe goes on forever and my daughter (8 years old) said “how can it do that?” . I said “well, what do you think would be at the end if there was an end?” ….she thought for a little while then said “ A full stop?” 😁💕
  • @loco4loco
    The fact that this came out only 7 days after the last one is quite impressive
  • @badteen
    Greatly explained. Loved it Big thanks for the vid ❤❤
  • @arunrana9887
    just wow, the story telling, the animation, the logic, everythings perfect.
  • @user-jd7dr4yr9y
    The idea that there could be endless galaxies, stars, and possibilities out there is both exhilarating and humbling.
  • @RHLW
    "Maybe a copy is living the same life as you, but wearing a funny hat". Lol, Im wearing a funny ha... omg, Im the funny hat copy arent I?
  • @AnjuK-gf2rk
    Man, there's nothing like watching a Kurzgesagt video and questioning the importance of my existence. Love this channel!
