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
  • @ClaubynBoi
    The universe is growing so once you reach the edge you have to wait until the devs come out with a new update
  • @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???? 😭😭
  • @forgingluck
    "only boring stuff repeats itself" definitely a few million infinite copies of me in the infinite universe then
  • @cooldude702
    ah yes, another tuesday afternoon where i question my reality and the universe while watching a Kurzgesagt video, perfection.
  • @elemiraii
    My English has improved so much that I have been able to understand this video 100% as someone who speaks Spanish. I love these videos, both the ones on the Spanish channel and the ones on this one.
  • @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
  • @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?
  • @eljuano158
    Props to the cameraman for finding thousands of identical earths in straight lines for this video
  • @watema3381
    At the highest level, this mirrors Minecraft. Think about it: - Infinitely generating worlds - Each generated world cannot interact with another - The "true" World Border it at around 25 pentillion meters away before things start to break down - During a normal playthrough, it would be impossible to explore an ENTIRE seed (i.e. world), let alone every single possible one Just a thought
  • @TheDramacist
    "Living your exact life, but wearing a funny hat." I AM that version of myself.
  • @loco4loco
    The fact that this came out only 7 days after the last one is quite impressive
  • I was like 8 years old when I came up with the theory that the big bang was caused by a singular black hole that sucked up everything that existed before and then released everything all at once. Still my favorite theory
  • the part about infinitely recurring things reminds me of something i heard a long time ago: if you put and apple in a box for eternity, the particles will rearrange themselves in every possible way until you end up with the same apple!
  • I remember reading something somewhere a long time ago: "When infinity gets involved, possibilities become certainties"
  • @markusb3712
    4:02 The animation of the sphere turning with all its stars is so satisfying!
  • @drkpaladin777
    Even if the universe is finite, time stretches ahead and behind this moment infinitely. 🤯
