The Afterglow of the Big Bang: The Cosmic Microwave Background

The Cosmic Microwave Background [CMB] is the oldest light in the universe that we can see or detect. It was emitted only 380,000 years after the universe was born, back when it was a much less peaceful place. The microwave-band static is fundamentally linked to the Big Bang, and if we map it precisely enough, we can discover a wealth of information about the age, composition and structure of the universe.

“From nano metres to light years in microseconds”

That… scares the shit out of me for some reason… the sheer power of that. Wow.

What I love about this channel, which I discovered recently, is that it's not just Wikipedia + space visuals, it has this unique existential vibe, much like watching 2001: Space Odyssey.

[hylacinerea]

when i learned about static’s origin as a kid i’d leave the tv on the un-tuned channel because i thought it was very cool

[LoneWolfeMedia]

Sea,

Your content is not only breathtakingly beautiful, but infectious and inspirational. I’ve long desired to dedicate my life to the stars and the search for answers, and you’ve given me the inspiration to keep that dream alive!

[facilis]

This day suddenly got a whole lot better - SEA uploaded 💪

[ballsinspector]

i watch sea's videos at least twice. once to watch it, the second to fall asleep to it. his voice is just so relaxing and helps me sleep.

[Lunar_lunaa]

I’ve missed your videos SEA!!!! Thank goodness you’re back. Hope all is well!

[sketcharmslong]

Honestly dude your videos are spectacular. Not to mention how incredibly well researched they are, but still keeping that wonder and intrigue at the same time is brilliant. Thanks so much man

[denniskalter]

I am working at an airport, and every time I have to work at night I am listening to this channel while driving, so peaceful and beautiful. Also, I like watching stars at night with friends, and sometimes I play these videos and they love it, or I watch them after I watched stars with my friends. This channel reminds me of how little time we actually have, so we have make our lives something special. Thanks SEA for doing this❤

For all the og sea chads out there let’s give our man a big hand for how far he’s come.

[aaronbranson]

There's something to be said about your production values. Props. I appreciate the chapter integration. The attention to detail, and your passion for facts. Cheers mate. Much appreciated.

[heidetermeg]

This is one of the few channels I press the "like" button on, before even having watched the video.

It feels like christmas every time you upload a new video. Thanks for your effort, SEA <3

When I eventually die, I just want to soar around the universe forever. I want to see everything without bothering anyone or anyone bothering me. Just soar and soak in everything. Even at its worst and most destructive, the universe is still beautiful and perfect.

[yourboysgottem]

I downloaded SEA’s entire space playlist and listen to it every night before falling to sleep

[dogsoupblues]

I am subscribed to hundreds of channels, but yours is the one I always anticipate and look forward to most. Thank you!

[ZakisHereNow]

These just keep continuing to amaze me. I’ll rewatch this and your other vids several more times because they’re that good.

[sssplllattt]

hats off to you for adapting to this channel's viewership. with newer videos, i could not imagine a better style of youtube films to doze off into the realm of peaceful sleep. it does so in as perfect of a way as is possible, and i find myself rewatching the older entries on this channel simply because i became so invested in hearing about the cosmos from SEA's signature narration - lulling, yet clearly pronounced. hats off

[hipioty]

I was waiting so much for a video from you. Definitely my favorite channel with space related stuff💜 Thank you for existing Sea, big respects and greetings from Sweden!

[starknit]

when i feel sad or unimportant, i watch your videos to remind me that there are greater things beyond us

[moelr_]

Absolutely brilliant video. This is the best channel I have ever come across. Thank you for these masterful videos man.
As soon as I am financially stable again I'll become a SEA Squad Member and donate extra per video because this content is just too well produced to be watched for free in my opinion.
