Beyond the Observable Universe [4K]

What we perceive to be the edge of our universe is not the actual edge of the universe, with most scientists in agreement that more space lies hidden beyond what we're able to see. Last time out, we travelled to the very edge of our observable universe. But today, we will be going even farther, as we wade out into the darkness of the unobservable universe.

If you use these videos for sleeping, check out the Sleeping Space Playlist! It's a collection of my most chilled out and audible videos, suitable for shuffling.

Thank you to everyone who watched and enjoyed this. I’ve been planning this vid for more than 2 years and I hope you all enjoy watching it as much as I did making it. Merry Christmas and see you in 2023 🍺

my name is kuiper and im autistic and my special interest since i was really young has been space. I watch all your videos over and over and i never get tired of them. You make the most informative and comforting videos on space and there’s nothing better than your content in my opinion. your content makes me so so happy, and i love sharing these videos with all my friends too! these videos help me sleep too and i just can’t thank you enough for what you do <3 you’re always up to date and you talk about these complex things in such a way that makes them so understandable! i wish i could offer more, and hopefully i can eventually buy your merch!! thank you for what you do :)

I was born with many difficulties in my life. Although I am not fully educated, I have a strong love for science and the universe. Thank you for bringing it to me. Love you

It's ten minutes to 3 in the morning. There's a blizzard raging outside and i'm curled up in bed under many blankets watching this video. I've never felt at once so large and so small; so tethered to my immediate physical time and place, and so free to wander a possibly infinite universe. This video is a master work. I love that we know so much, and I love that there is so much we may never know.

It’s amazing we get to watch this level of content for free. This channel is way better then the stuff I see on Netflix. He goes into such depth with facts that are actually true. The video is 40 minutes of actual knowledge and i love every second of it .

[StardropGaming]

Came out of this understanding less than what I understood coming in. This is how you know when a science video is amazing.

[Krebssssssss]

I love the idea of a cyclical universe, where everything begins anew, instead of every photon and proton eventually decaying into nothing, and the universe becoming a graveyard of what once was. But I also understand that the universe is under no obligation to make sense to me or bend to my wishes. This content is so awesome! Thanks so much!

[reedreed]

I play your videos for my astronomy students pretty regularly and they are always in awe at what you're describing. As the semester is coming close to an end, I cannot wait to show them this video after watching the cosmic scale at the start of the year.

Thank you for making such fantastic content!

[mofomo]

The cyclical, never-ending, forever identically looping concept of a Toroidal Universe is both supremely terrifying and deeply comforting.

[LoneWolfeMedia]

From the bottom of my heart and soul, thank you so much for another trip around the sun. Your content has become a fixture of my life and it's been an absolute pleasure and honor to have supported you since 2019. I look forward to another year of reaching for the stars! Merry Christmas and I'll see you in 2023!

As always such high quality content. You put a lot of work into it and it shows. Great episode.

[grantmeacham]

I watch videos like this all the time and you had by FAR the most understandable explanations for some very trippy concepts. Well done!

[wossengetachew]

Am not surprised anymore with this guy.

You won't find a science show on Netflix or anywhere with this quality and clarity that just focuses on the science like this. And it's just one dude🤯.

Done it again hats off to u Sir.

I’m convinced the very best of humanity can be found in the comments of SEA videos.

[SirDuck]

Bro I’m so glad that this channel exists it has helped me sleep better and be more comfortable because I never really get to do anything or just hear about one of my favorite things space so when I go to sleep I listen to one two or even three a night.

[Robbo]

Education is the key to mankind's salvation. Thanks for this!

[huhuruz]

I feel like I'm at school where my favorite teacher teaches me one of my favorite subject and I absorb every word from him. After the class is over, I will remain in a pleasant state and look forward to learning more next time.
SEA creates a state of dependence that I have never encountered before, not even with Neil deGrasse Tyson, who has a very pleasant style of telling stories and making himself understood by every person on the planet.
Addiction is more beautiful and sweeter with SEA! Thank you so much !!!

[StarlahMutiny]

Not only is this video immaculate, but the comments are so wholesome and quality. Humanity lives!

[RobinCrusoe]

In the 70 years I've been on this planet I've witnessed more changes than any previous generations in human history.
What man and woman have achieved in a blink of geological time leaves me stunned with awe.
As do your presentations.
Happy Christmas

Started watching science stuff on tv long ago. Hated how it went from approaching education to just being wonder porn. Came to YouTube and found stuff like this which almost forces you to pause and search to learn as you watch. Basically free 100 level college lectures. Love it.
