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.
-
Every Kurzgesagt video: - Facts - Scares you - Then calms you down - Add birds
-
The universe is growing so once you reach the edge you have to wait until the devs come out with a new update
-
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???? 😭😭
-
ah yes, another tuesday afternoon where i question my reality and the universe while watching a Kurzgesagt video, perfection.
-
"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?
-
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.
-
bro this is the peak of youtube animated content
-
"only boring stuff repeats itself" definitely a few million infinite copies of me in the infinite universe then
-
"Living your exact life, but wearing a funny hat." I AM that version of myself.
-
Props to the cameraman for finding thousands of identical earths in straight lines for this video
-
Greatly explained. Loved it Big thanks for the vid ❤❤
-
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"
-
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
-
just wow, the story telling, the animation, the logic, everythings perfect.
-
The fact that this came out only 7 days after the last one is quite impressive
-
4:02 The animation of the sphere turning with all its stars is so satisfying!

Timestamped Highlights 00:31 🌌 The observable universe is a sphere with a radius of 45 billion light years. 01:49 🍊 The universe could be finite and shaped like a hypersphere or a hyperdonut. 03:29 🌌 A hypersphere universe would be at least 1,000 times bigger than our observable part. 04:56 🍩 In a hyperdonut universe, spaceships flying in different directions would reach the start at different times. 07:04 ♾ An infinite universe has no borders and goes on forever in every direction. 09:26 👥 In an infinite universe, there could be infinite copies of ourselves. 11:45 🌌 For us, the universe is finite and has an edge in time.
