25:33 The red warmer areas of the CMB were warmer and therefore LESS dense and LESS massive. The cooler areas were denser because cooler gasses and plasmas are denser. The cool, denser areas then collapsed gravitationally while the warmer areas expanded and became the voids. Stars form in the same way, from cold, collapsing gas clouds; not hot expanding ones.

The thing about SEA is that it makes a huge difference listening to someone who has a really deeper understanding of his subject to someone who does a quick research on a subject requested by a viewer. In that way SEA is the needle in the haystack of Pop science channels. As always great Video. Keep going! ♥️
A little too much parroting without any questioning for my liking. Puts out a a fair amount of questionable info. And keeps referring to unknowns as fact. As did Einstein...the smart one was his wife. E=mc² was her. She put out her science through him as women weren't readily accepted in the field. He never corrected history before he left us. So i will :) einstein was a git
Thanks for all the great videos, and keeping them free for everyone. I am donating on behalf of those who benefit from these videos but might not be able to donate right now. No clickbait filler crap, no long intros, just pure informative videos. Keep it up.
If all points in space travel faster than light then all points will travel back in time. So maybe the big rip is just the beginning of a temporal crunch a new universe.
You might enjoy reading "Last Contact" by Stephen Baxter. It's a very short short story about the last moments of humanity in a scenario where the Big Rip occurs. It's just a few pages long so it's very easy to read.
@@manofcultura it's not matter that is expanding FTL but the space between. The matter stays stationary within the space and is not effected by relativity and time dilatation. Thus that matter can't travel back in time.
Your series on the cosmos is more exhilarating and engaging than 95% of everything on Netflix and Amazon combined. I'm a huge fan and I really loved the soundscapes on this one. Excellent visuals, great stuff. Thank you and please for our sake, keep it up. ✨
How scary an ending would the big rip be? Watching galaxies become unbound, star systems torn apart, then stars and planets themselves. What an amazing island in time we find ourselves in
I believe I’ve heard before that you were interested in space and just started researching and creating these on your own, if so this is absolutely amazing. Absolute top quality documentaries. Never stop. Thank you for making this information so accessible!

History videos too dull, kinda boring, creepy mysteries were a sure fire way to get demonetised, but space content ticks both these boxes and there’s some great tools available to make graphics. That being said I have always been interested in space since I was a little kid. I was obsessed with big stars like Canis Majoris at like 12 and astronomy was the only module I really enjoyed in science class. So I had a basic understanding, all I had to do was research topics. And I like researching and writing so it’s worked out quite nicely 😅

i am very grateful that there exists a channel as dedicated and coherent as SEA for a branch of science that interests and intrigues me greatly. some fields lack such a channel and it's definitely a loss for them. thank you for another great video!
Dude... This is long overdue. You are an incredibly dedicated and consistently great content creator. Professors will one day reference your channel as a template for what independent creators of this period were capable of producing.!
Sorry I didn't see this sooner, thank you so much for that incredibly generous donation 💙🙏🙏 It brings me great joy to see people enjoying these videos to such a degree that they feel this way. Regardless of the future brings, I shall keep producing 😊 Thanks again 💙🙏
Hi sea! I've been following you for over 4 years now, and seeing you improve your content to such an extent makes me really glad I stayed for it! I myself am also quite passionate about astronomy and find all your documentaries to be very constructive and interesting to watch! I would love it if you kept it up!
@@SEA You were probably my favourite GD youtuber back in the day but with time as I became more invested in space and revisited your channel, I was super happy to seeing you post such high-quality stuff!
Please never stop making those documentaries about space. The level this is on cannot be compared with anything Ive seen on heared. I cannot count how many times I replayed all of those. Its so fascinating and educative
Sea, I just want to say that 6 years ago, I discovered your channel through the maps from hell series and I tell you I have not been disappointed at any point. Thank You for this great content Sea.
Hello SEA As a physicist, it was my usual pleasure to review your latest production here. With very good factual content and lovely production values, I have no hesitation in recommending this video to my own students and to any curious layperson. It is definitely up there in technical quality with, say, Arvins Ashe's or the PBS SpaceTime series. The perfectionist troll in me will pick out the occasional technical mis-statement or misleading remark - very likely slipping in no doubt at scripting time - but taking away almost nothing from the value of the presentation. Please DO keep up the good work - I enjoy most seeing the other comments here of curious folks enjoying science more because these videos!! best regards D. Barillari
You're the perfect person to talk about this kind of stuff it just seems to come natural maybe the universe pick you to do these types of subjects for a reason bc ur fn awesome at it
Hey SEA! I happily subscribed to your highest Patreon tier, and I can't believe how few patreons you have. It's obviously not for lack of quality content. I get the sense that it's not your style, but I humbly want to recommend bringing attention to your Patreon at some point during your videos. Anyways, thank you for the truly wonderful documentaries.
Thank you for becoming a Patreon and supporting the channel! I made the account about a week ago so it’s still early days and I have only plugged it once but from here on I’ll aim to do it subtly here and there. Still figuring out how to use it tho
@@SEA I only realized after revisiting your page that it was very new. My bad! And best of luck. I'm sure much of your community would be happy a contribute a little for each video.
To all involved with this video from the narrator and writers and the artists and videographer and all the scientist , fantastic job well done making a the subject matter easy to comprehend and enjoyable. The voice of the narrator keeping me interested. Surely this won awards and deservedly so.
This one went way over my head but I enjoyed it so much . SEA are amazing to make a 2 part video about something we know nothing about . Some of your best work yet my friends .
These are the best space documentaries on the internet. Thank you for all your hard work and excellent content entertaining us with the most fascinating and mesmerizing subjects known to man.
you were always one of the more talented GD creators, so glad to see you making these high quality interesting documentaries for a much larger audience :)
I feel a bit sorry for little Sagittarius. I love this channel. You break everything down so that just about anyone can understand it. I listen to this playlist to fall asleep to. Better than any sleeping pill.
This one is my favorite one so far. When I'm not asleep listening to the Sleep Playlist, I play this one wide awake at night learning how I'm accelerating across space in my bed. Thank you for this masterpiece!
Just gotta remember that the reason they are called dark energy and dark matter is because we are "in the dark" about any of their attributes, like what its made of.
Your videos are so insanely high quality. Been looking forward to this video ever since I saw the dark matter one. I hope your channel keeps growing exponentially and that you'll keep reaching people with this amazing science!!
SEA vids help me sleep by reminding me of how vast the universe really is and how much we dont know about it, which makes our worries here on Earth really tiny in comparison. Love this channel
Another brilliant take of our universe's mechanics. Thank you for the education and, more importantly, for all the work that was put into the making of this video. 🥂 Cheers!
I don't even need to get past 0:01 before giving your videos a thumbs-up. Now if only there was a super-like button I could mash after watching it. . .
@@Gafferman excellent content that I can listen to over and over. So much information. I can listen just on my headphones as I work or sit and watch. I've listened to some of his videos maybe 50 times. Why do you ask?
@@MrJimtimslim you're not a bot! Thank goodness. It's just that this channel seems to have sadly had a lot of generic vague "this channel good" comments every time I come on here and it's genuinely got me curious.
I’ve watched this one like 6 times and continue to pick up something I missed be it visuals or information. You have the best videos, man. Thank you so much!
Question: how do we know the CMB is a snapshot of the universe at a certain point? Especially since it apparently corresponds to the universe we observe today? Serious question. Thanks!
It is the last light emitted after the recombination era. It is a nigh perfect blackbody, basically as cold as anything can get - it was predicted that such a radiation would exist and cool down over time. It is also universal and not linked to any current source of radiation. By looking at the CMB it's possible to trace current existing structures, thus implying it's an earlier "photo"
Pretty new to the channel and watched a lot of the old videos, love the content, delivers the perfect amount of information that makes so much sense to me. Love astronomy and you sir rekindle my love for the unknown. Don't stop what your doing cuz it's perfect. I'm so excited to finally be here when you released a new video
These are the best late night UA-cam videos I've ever seen. I'll literally punctuate a period of my life starting around Covid, with your videos. Astounding...
When you enjoy a 40 minute space doc and not once feel like getting stoned, you know it's a good one. 👍👍That said....I am stoned but I know I'd enjoy it regardless. Great stuff man, really.
For those who really liked the big rip part, Kurzgesagt as wel as some other space focused channels have great videos about the ending of the universe. Can't go wrong with loading up some more existential crisis things and realisations of how meaningless and powerless we are as mere humans in the confines of the great infinite dark.
Absolutely brilliant video as always. These videos offer a lot more information than any other on similar topics on UA-cam. The resource time must be massive. Keep up the great work I can't wait for the next video.
Looking for informations about space ? Look no further because you've reached the best Space-Documentaries-Channel on UA-cam ! Darken your room, wrap yourself in your cozy blanket and prepare for an enigmatic, strange, dark and inexplicable mysterious trip to the edges of the known universe. No cheesy meme-inserts, no funny sounds, fantastic editing, gorgeous soundtrack and (imho!) the most amazing narration i've EVER heard. Every episode is in fact so well produced, it's mind-boggling. THIS is what a space documentary has to look, sound and feel like. Rating : 10^100 out of 10 ironstars !
Fantastic vid dude.Your production values are so high.I do like how there are still mystery’s out there.The jwt maybe showing the universes earliest galaxies but we still don’t know what pushed them there.
Gravity is actually a VERY WEAK force that most other forces easily can overcome. Humans on the other hands are still just mentally challenged cavemen who can barely put together a space-rocket capable of escaping earth’s incredibly weak gravity. And our lack of such basic skills in physics knowledge is our baseline, so I totally understand why most humans does not understand the mechanics of the universe. That being said. I enjoyed this video very much. Amazingly high quality content. ❤👍
I actually did not know a type-1A supernova was used in this manner for red shift measurements and expansion until this video. For some reason, in my mind, the standard candle was a Cepheid Variable (pulsing) star. I must’ve mixed that up with another form of measurement-for example, these two standards are used for two different issues, namely 1) location within a galaxy (cepheid) vs. 2) movement and expansion of space and objects within it (type-1A). However , I haven’t looked this up and am probably getting something wrong here. Regardless, thanks for continuing to teach me new things regarding cosmology and astronomy. I’m a huge fan and look forward to learning more from your research and videos. Much love from America 🇺🇸!
You are right in that standard candles constitute a wide range of luminous phenomena depending on what astronomers are trying to study, and indeed Cepheids have been used for things like the Andromeda Galaxy, and also Red Giants at the tip of the RGB for things like the Triangulum Galaxy. But when it comes to the very farthest distances, it's the type 1a supernova because we can't use RGB stars or Cepheids to accurately see billions of light years back, their light is too faint not to be hampered by the distance and dust in the way. Thank you for your support, hope you can continue to learn from and enjoy the channel :)
@@SEA That makes a lot of sense. Thanks for getting back and explaining it! Very helpful information. I love a UA-cam creator that connects with their fans. Keep up the outstanding work my friend.
I have beef fascinated by Dark Energy for years. I've seen many videos and read everything I can find a out it. This is without doubt the best explanation of what the current paradigm says about Dark Energy. Excellent work. Thank you.
In a SEA of AI-made science "documentaries" on UA-cam, it's nice to see a real video, by a real person, with real info that isn't a regurgitation of someone else's work
These are the best science videos on the internet. You have an incredible gift for explanation. I'm shocked that I'm able to comprehend any of this! Thank you!💫
For the record, your amazing videos and soothing narration don't make me drift off into sleep. Rather, absorbing facts and theories of our universe keep me wide awake! Not a complaint, btw
Watching these types of videos makes me so glad I got an OLED 🤣 I usually feel like I wasted my money, but this type of content is perfect for it. Good shit 👍 Edit: thanks for such hi-res content. Also, the soundtrack is very appropriate. Great job all around.

Right, you're bloody well right. You got a bloody right to say 😊
Absolutely brilliant video as always. These videos offer a lot more information than any other on similar topics on UA-cam. The resource time must be massive. Keep up the great work I can't wait for the next video.
The long awaited sequel! Thanks I love these so much
Looking for informations about space ?
Look no further because you've reached the best Space-Documentaries-Channel on UA-cam !
Darken your room, wrap yourself in your cozy blanket
and prepare for an enigmatic, strange, dark and inexplicable mysterious trip
to the edges of the known universe.
No cheesy meme-inserts, no funny sounds, fantastic editing, gorgeous soundtrack
and (imho!) the most amazing narration i've EVER heard.
Every episode is in fact so well produced, it's mind-boggling.
THIS is what a space documentary has to look, sound and feel like.
Rating : 10^100 out of 10 ironstars !
Fantastic vid dude.Your production values are so high.I do like how there are still mystery’s out there.The jwt maybe showing the universes earliest galaxies but we still don’t know what pushed them there.
Thanks for bringing out content so quickly, seems about 2 mins ago you dropped the dark matter vid. Appreciate he hard work mate 👌🏻
Gravity is actually a VERY WEAK force that most other forces easily can overcome. Humans on the other hands are still just mentally challenged cavemen who can barely put together a space-rocket capable of escaping earth’s incredibly weak gravity. And our lack of such basic skills in physics knowledge is our baseline, so I totally understand why most humans does not understand the mechanics of the universe.
That being said. I enjoyed this video very much. Amazingly high quality content. ❤👍
This is my third watch of this. Hope I can watch this time without falling asleep! Love this channel, your voice is so soothing.
I actually did not know a type-1A supernova was used in this manner for red shift measurements and expansion until this video. For some reason, in my mind, the standard candle was a Cepheid Variable (pulsing) star. I must’ve mixed that up with another form of measurement-for example, these two standards are used for two different issues, namely 1) location within a galaxy (cepheid) vs. 2) movement and expansion of space and objects within it (type-1A). However , I haven’t looked this up and am probably getting something wrong here.
Regardless, thanks for continuing to teach me new things regarding cosmology and astronomy. I’m a huge fan and look forward to learning more from your research and videos. Much love from America 🇺🇸!
You are right in that standard candles constitute a wide range of luminous phenomena depending on what astronomers are trying to study, and indeed Cepheids have been used for things like the Andromeda Galaxy, and also Red Giants at the tip of the RGB for things like the Triangulum Galaxy. But when it comes to the very farthest distances, it's the type 1a supernova because we can't use RGB stars or Cepheids to accurately see billions of light years back, their light is too faint not to be hampered by the distance and dust in the way.
Thank you for your support, hope you can continue to learn from and enjoy the channel :)
@@SEA That makes a lot of sense. Thanks for getting back and explaining it! Very helpful information. I love a UA-cam creator that connects with their fans. Keep up the outstanding work my friend.
I have beef fascinated by Dark Energy for years. I've seen many videos and read everything I can find a out it.
This is without doubt the best explanation of what the current paradigm says about Dark Energy. Excellent work.
Thank you.
The editing is getting better and better!
One of the best episodes about space I’ve ever seen. In my entire life.
Always excited when a new Sea video posts!
In a SEA of AI-made science "documentaries" on UA-cam, it's nice to see a real video, by a real person, with real info that isn't a regurgitation of someone else's work
AI generated content makes me die a little more inside every time I see it, so thank you for your kind words 🙏
Excellent video don't ever stop doing what you're doing!
amazing vid, i love all of your videos. SUPER
Bro, every time you say “supernoveeeeeiiiii” my eye starts twitching
Kudos to the creater for making learning an engaging affair.
These are the best science videos on the internet. You have an incredible gift for explanation. I'm shocked that I'm able to comprehend any of this! Thank you!💫
Aaaah this made my night! Perfect time to find out you uploaded a new vid
Incredibly thought provoking and informative video as usual SEA. Keep up the great work :).
For the record, your amazing videos and soothing narration don't make me drift off into sleep. Rather, absorbing facts and theories of our universe keep me wide awake! Not a complaint, btw
my guy always puts in work with these videos. fr thank you
Fantastic quality!! Thanks for the hard work.
Great video, beautiful images and mind bogglingly awesome as usual! Thank you for sharing.
My favorite Space Channel on UA-cam by far
I really really appreciate the consistent volume levels
Watching these types of videos makes me so glad I got an OLED 🤣 I usually feel like I wasted my money, but this type of content is perfect for it. Good shit 👍
Edit: thanks for such hi-res content. Also, the soundtrack is very appropriate. Great job all around.
I wait with baited breath for each one of your videos!!! ❤ thank you for your contribution to society!
this dude is the best astronomy youtuber, or even teacher out there, sorry Mr DeGrasse
this blew me away. nice video man :)
i love the way sea went from a gd documentary channel to a mesmerizing space channel
Great video, man. Given enough time, I'll bet this gets lots of views. The Universe is mind-boggling beyond description.
