The Paradox of an Infinite Universe

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.

[cooldude]

ah yes, another tuesday afternoon where i question my reality and the universe while watching a Kurzgesagt video, perfection.

[ClaubynBoi]

The universe is growing so once you reach the edge you have to wait until the devs come out with a new update

[eljuano]

Props to the cameraman for finding thousands of identical earths in straight lines for this video

[betterchapter]

Every Kurzgesagt video:
- Facts
- Scares you
- Then calms you down
- Add birds

[forgingluck]

"only boring stuff repeats itself" definitely a few million infinite copies of me in the infinite universe then

[simonstalenhag]

bro this is the peak of youtube animated content

[xmysticmushroomx]

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!

4:02 The animation of the sphere turning with all its stars is so satisfying!

[josejavierbruzual]

I remember reading something somewhere a long time ago:

"When infinity gets involved, possibilities become certainties"

[-yumefroots-]

I'd like to take a moment to appreciate the artists on this channel. Some of these concepts are impossible to visualize, and yet they still try to represent it in an accurate way. This helps me especially, because I'm a visual learner. I also appreciate the usage of analogies to help people understand better. :-)

I love how this little cute bird is discovering and exploring the CONCEPT OF LIFE.

9:23 "because you are as real as real beings get"

Thanks dawg, you too are a real one!

[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?

[drkpaladin]

Even if the universe is finite, time stretches ahead and behind this moment infinitely. 🤯

[CalebGarner-xywt]

This is my favorite video of yours so far. I love the concepts you guys have dug into here. It makes me happy to see people thinking together this deeply.

[locoloco]

The fact that this came out only 7 days after the last one is quite impressive

[jddryry]

The idea that there could be endless galaxies, stars, and possibilities out there is both exhilarating and humbling.

[watema]

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
