The Dark Energy Mystery [4K]

- čas přidán 26. 06. 2024
- In 1998, two teams of scientists measured the universe's rate of expansion, expecting to find the gravity of the Cosmic Web bringing the universe into a collapse. But instead, they found that the universe's expansion appears to be accelerating- having expanded more in the latter half of its life.
Both teams agreed upon the existence of a new type of energy field, known as Dark Energy, to drive this acceleration, and in doing so, they revived one of Einstein's long-rebuked ideas- the Cosmological Constant.

These videos are superb, bravo to you man...
Did you re-release this?
@@WilliamFord972 Yes, in 4K I believe...
Agreed
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.
Best and worst thing about these is the fact that they are super interesting and yet make me sleep so fast.
?
I listen to his work every single night almost. I have pretty much retained all the information on the sleep playlist. What's your favorite video? Mine is likely when black holes collide.
@@lol-dj2hv Loneliest planet is mine.
Yeah, I have watched these videos just before sleeping. Could help to see interesting dreams also. :)
WTF!?
this dude legit makes best space documentaries on YT... period...
yeah, along with Astrum I have all my space bases covered!
Absolutely.
Yup!
I'd also suggest a channel called kosmo
@@ezyyze7526
And melodysheep.
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! ♥️
SEA doesn’t have a degree in astrophysics or anything like that. I’m pretty sure he just does research online
both types of channels have their merits
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
That last section on the Big Rip gave me so many chills lol. Thank you SEA for this amazing documentary, keep up the amazing work. 🙏🙏🙏
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.
Same! That was terrifying!
@@manofcultura made in heaven
@@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.
Watched the whole video. Well done mate, well done. I'm impressed to say the least. Great work and thanks for a solid well spent 41 minutes :)
And thank you for the awesome soundtrack that completed it! It’s been great working with you!
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
Allowed to observe until our gourds explode. Quite amazing indeed to be here.....its scientifically spiritual.
I'm baffled by the fact that this man didn't reach 1M yet
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. ✨
After almost 15 years of watching videos on CZcams, of all kind, this is the 1st and only channel I've subscribed to.
Premium content and narration.
Ok. Just to test this isn't a bot comment, care to state what the content is about?
What kind of crazy person uses youtube that long and doesn't sub to anything??? I'm subbed to over 700 channels. You're doing it wrong.
@@Gerlaffy lol it did sound a bit too botty true
I can't believe this.
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!
...his channel started with some videogame fan stuff. Then he did a couple of these science videos and... the rest is here.
Terrible what people do without the guidance of government schools. /s
I did indeed I was looking to branch out from gaming and was mulling creepy mystery videos, space videos and history videos. 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 😅
@@jengleheimerschmitt7941 video game fan stuff 💀💀💀 if only you were around for the GD days
@@sea_space 😁 Love You SEA. I wasn't. I came for the best science narration on the web.
@@sea_space I absolutely didn't mean that as a slight, Sir. I hold you and your consent on the highest regard.
I just don't know anything about video games. What I meant was that your burst to the top of the Cosmology podcast world was sudden and masterful.
These videos are getting better and better each time you post! Not just a piece of content, but a treasure
Thank you for what you're doing to bring us these, absolutely worth the wait♥️♥️♥️
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.
Thank you so much! That’s a very generous amount and much appreciated 🙂🙏
There is also many like myself that are Premium subscribers
Your videos are masterpieces, and as a person who has been a spectator of your work since your early geometry dash days, it's amazing to see what you have become. Never change Sea
41 minute video heck yeah thanks for your effort
Could have been 45 minutes to be fair mate, I don't rate the 42m.
@@alexanderinsubordinate1861 it's okay with the amount of ads youtube shows these days you can chalk it up to 45 minutes :)
Why don't we meet in the middle before we all miss it.😂
Testing for bots, aside from the length of the video... Any thoughts on its content?
@@Gerlaffy sad life you got there bots are everywhere. As for the video saving it for a good day before I fall asleep
Do you study astronomy, or is it just a hobby of yours? Great video as always
Never stop making these videos. You make this comprehensible to a non-astronomer like myself. I love it.
My day just got awesome. Thank you for the superb work SEA.
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!
4 years you would’ve been just coming in at the start of the space stage! So sorry about the crappy tabby’s star video
@@sea_space 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!
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.
I didn’t know he had a Patreon page actually. Thanks for bringing it to my attention!
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_space 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.
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
SEA always has the greatest space content. Only wish I could’ve found him sooner so as to have subscribed sooner.
Haze, sunset sherbert some Skywalker and a Dark Energy video by Sea.
Lets go baby
Your content is always so fascinatingly presented and well made, I love it.
I always have these videos as background sound when drawing or sleeping.
@@struttux5156 you can get audio-only versions for listening / sleeping on SoundCloud!
Thank you Ethan 🙏 💙
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
Wow, that part about the big rip genuinely invoked dread in me, had goosebumps, nice work! Awesome video, as usual.
I was relaxing when I randomly remembered this guy. He used to make Geometry Dash documentary videos that were actually really good, and I tried to rewatch them, but it looks like he deleted all of them from his channel. Why? They were good videos, why remove a large part of your history from the platform like that?
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.
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
Easily my favourite channel on CZcams, the visuals, writing, voice over, and music are always outstanding!
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 .
SEA and History of the Universe: the ultimate crossover... want it so much
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 introduced me to this concept in one of your previous videos so, it's only fitting you educate me further.
Thank you.
Incredible video. The presentation style and the script are awesome. One of your best ones yet!
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!
Love your videos dude. They are both extremely interesting and well researched, but are also a great sleep aid :)
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 :)
thats a scam
Kudos to the creater for making learning an engaging affair.
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!
Time to get a little more knowledgeable. Thank you for your work SEA :) 💪
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!!
Absolutely brilliant video as always. These videos offer a lot more information than any other on similar topics on CZcams. 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
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!
Thanks for your top class videos !
Thank you so much for the generous donation and support 💙💙
Thanks for bringing out content so quickly, seems about 2 mins ago you dropped the dark matter vid. Appreciate he hard work mate 👌🏻
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.!
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
Amazing content. My absolute favourite channel
Just a test here, why is this your favourite channel?
@@Gerlaffy 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?
@@Gerlaffy I also find his voice very relaxing and it helps me sleep.
@@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.
Definitely one of my favorite documentary/commentary channels for sure
Incredibly thought provoking and informative video as usual SEA. Keep up the great work :).
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.
Braindead take
Spectacular stuff as always. Glad it's a British Channel too.
This is my go to channel for helping me sleep. I absolutely love learning about the intricacies of cosmology as I unwind from the day.
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. . .
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"
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.
These are THE BEST VIDEOS MAN every time you upload I get so hyped thank you SO MUCH for making these
We may need to wait for a long time between videos, but at least I know they are always worth it. Solid content keep it up!
One of favourite episodes yet mate, keep up the amazing work :D
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!
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!💫
i love the way sea went from a gd documentary channel to a mesmerizing space channel
Great video, beautiful images and mind bogglingly awesome as usual! Thank you for sharing.
The fun part about all of this is that in the space of a few hundred years humanity went from banging rocks together, to trying to understand the universe's internal clockwork.
No, we don't know where it's headed, but someday we likely will. The journey to that understanding is the fun bit.
I've heard people talk about expansion, red shift etc.. a thousand times, but something in this presentation really made it click. Thanks!
Always excited when a new Sea video posts!
my guy always puts in work with these videos. fr thank you
When you post a new video I feel such a joy... it is hard to put into words. Thank you!
These are the best late night CZcams videos I've ever seen. I'll literally punctuate a period of my life starting around Covid, with your videos. Astounding...
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
The editing is getting better and better!
I've showed your channel to many of my friends and they've been converted as well.
One of the best episodes about space I’ve ever seen. In my entire life.
This is amazing! You are Amazing!! Thank you for providing these for free.
Aaaah this made my night! Perfect time to find out you uploaded a new vid
Fantastic quality!! Thanks for the hard work.
I really really appreciate the consistent volume levels
Bloody hell, imagine how hard it must've been for Einstein. Even when he was wrong, he was right.
Right, you're bloody well right. You got a bloody right to say 😊
this blew me away. nice video man :)
heck yeah! i was just thinking about this channel and how i wanted to watch more space stuff
Best videos I have seen till date! You are doing a fantastic job
Great video, man. Given enough time, I'll bet this gets lots of views. The Universe is mind-boggling beyond description.
Thank you for your time and effort for us to enjoy!
Mate, you have a way of explaining things that even a relative physics pleb like me can sort of wrap my head around.
I wait with baited breath for each one of your videos!!! ❤ thank you for your contribution to society!
Absolutely top-notch, as always!
Great explanation of Dark Energy. Best one I've heard on YT.
Always look forward to your videos. Great content. Thanks.
Nice. Been waiting for this video :)
Oh snap best content just dropped and my current favorite subject and creator. It’s gonna be a good night
i've been waiting for a new video for sooo long
Fantastic to wait for! Thank you!
As usual, amazing content!!! Thanks so much🔥🔥🔥
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.
Great to see a new video from you! I hope you are well, thank you & Be well!!!
Excellent video don't ever stop doing what you're doing!
Absolutely loved this. Thank you for the amount of information provided. You got my likes and subscription.
this dude is the best astronomy youtuber, or even teacher out there, sorry Mr DeGrasse
