The Largest Black Holes [4K]
ฝัง
- เผยแพร่เมื่อ 21 พ.ค. 2024
- Lately, there has been talk of a new largest black hole, named Phoenix A*, which is said to have a mass greater than 100 billion times the mass of the sun! This is much larger than the previous record holder, TON-618. But can we really rely on this prediction? And if not, then what is the largest black hole out there, and how do we know its true size? These are the questions we will answer in search of the universe's biggest black holes.

In my opinion , this is the best Space Channel on TH-cam. I recommend watching ALL of his previous videos.
I just did it this weekend.
@@ikelevermann1491 the ones based on The Cosmic Scale and Great Attractor are 2 of my favs.
100% agree. SEA needs a team and a budget so he can pump these out at a higher rate and maintain the same incredible quality!
True.
@@nameatrandom9234 The one about the Pulsar is my favourite. Everybody is fascinated by the Black Holes but the Pulsar is the real banger imo. The thought that a 20 km ball of the hardest matter spins near light speed and shoots laser out of the poles is mindblowing.
Thank you for your videos. I‘m a physicist and deal with related topics ten hours a day, but still thoroughly enjoy every moment of your content and still learn something new every time. Again, thank you and I hope you can continue making these amazing cinema class short movies.
Thank you for those kind words and for the generous donation 🙏
I wish I had your job. Although I make pretty good money, I detest what I do. What I would give to back and finish a PHD with a focus on modified relativity
@Michael Renouf then do it the only thing that is stopping you is yourself.
That's a huge compliment!
Physicist, smysicist. Get a real job
I legit have seen every video 20+times. He's got the best playlists. I get excited for every upload. Thanks for the awesome content
Yeah, he's one of those creators who release a video every month/few months, but you watch it and it's so good, you watch it again, and the next day too, and by the end of the week you've watched it 5/6 times, and you rewatch the previous videos that you already watched over 10 times. I can almost recite the video about loneliest planets word for word, I LOVE THAT VIDEO!
I'm right there with you Levi. Al9ng with watching them for their content they're a go to when I try to fall asleep. And its not bc I find them boring in the least bit...theyre like counting sheep I guess lol.
@@mydogniko yeah, I find that the more I’m interested in a vid or podcast, the quicker I fall asleep. I have a lot of stress and think about work even though I try not to. If I’m really into something, it takes my mind off of work for a few minutes which allows me to fall asleep.
You're welcome!
I honestly can't count how many times I've rewatched his entire library
The thing to watch tonight
How about right now
Better than valium
Yeah!! TONIGHT!
I can’t wait. Might be late to work a few minutes
Hohoh I just used it to my siesta
Truly appreciate your work.
Thank you so much for that very generous donation 💙🙏
The last part left me in awe... to even imagine what the TON618 looks today is unimaginable. Space is so fascinating and it saddens me that we may never know the deepest secrets of the universe. Thank you for the video and keep up the good work!
WE might not know, but our great great great..... well, who knows how many greats, but the idea is, maybe one day one of them will finally unlock the biggest secrets, maybe not everything, but who knows what lies ahead I always say!
@@WildWombats i think if you have right equipement you can go close to ton 618
@@youngboy2pacdrake you can but not in this lifetime
@@singhji_437 why
@@youngboy2pacdrake we cannot reach the speed of light on a rocket. and these black holes are so many lightyears away. it takes a year to travel at lightyear at light speed.
Space content always feels like the most real and meaningful content to consume, even though it doesnt really intersect with our lives down here on earth, it's the bigger picture
@@ShaquilleBarron even when the ozone was being destroyed, it wasn't up to regular folks to change their habits, it was regulators and companies that made the difference. The truth is that space just isn't something the average person is forced to think about because it feels so distant and it's difficult to wrap your head around. Climate change is the closest society is coming to care about space, and even then climate change is arguably a closed loop system with a tenuous relationship to space. Space just isn't that relevant to the human quest for meaning and fulfillment down here on earth. Now of course, were there an impending asteroid collision, that would change real quick, but that isn't something society has been seriously forced to reckon with in any meaningful capacity.
@@ShaquilleBarron Well, that went right over your head.
Very detailed and interesting as always!🔥 Thank you a lot SEA, you’ve really made my day brighter with your video
Love that, glad to hear it!
Yet again SEA blows my brain cell. The best astronomy channel on TH-cam, bar none.
take care of that one cell, will ya
@@paszmaty Thank you. I try.
@@paszmatyit's working really hard
You only have 1 brain cell? 🤣
This is my second donation. Thanks for the hard work and keeping these videos free. SEA is bringing the highest quality space documentaries straight to the people. I like that the TH-cam age lets us support creative professionals directly.
Thank you so much Will for that very kind donation again! I’m so pleased you like the videos and super grateful for your support 💙 hope I can continue to bring you space info-tainment for many years to come 😁
I'm an aspiring astronomer, and I am especially interested in black holes for some reason, so thank you so much for teaching me so much about them, especially by making such complex topics so easy to understand yet still so interesting and entertaining.
You think the “information” in these videos is actually factual? 😆 I bet you’re an atheist… Lol
"Unrendered Space" is the most unique description of the event horizon that I've ever heard. That one is sticking with me for sure.
I hope you never change this format. SO many space docs are just full of way too loud music, and random talking heads who are all at different volumes, and too much swooshing and chimes with their sound design. Your presentations are so professional and, calming, for lack of a better word. Thank you for what you do, it's been great seeing your channel grow over the years.
I am addicted to your videos which I binge on while knitting or spinning yarn. I've found none better for describing and illustrating such difficult to comprehend material. Your production, narration, writing, and content organization are among the best I've seen in any subject. Thank you for such a valuable and fascinating channel!
This channel really takes away from the depressing draining world of social media with a really high quality and informative content
Anybody know how he gets the graphic rendering for all these? They’re absolutely beautiful and it’s usually a continuous movie for 90% of the video.
Part of me wants to see him get picked up by Netflix or Natgeo or something, but then the other part of me doesn’t want him at the whims of a mainstream platform.
Evidently he alot of trouble with the rendering on this one, in particular, to the point that it delayed when he actually intended to release it.
@@SteedRuckus Actually the delay was because I made a mathematical error in my on-screen comparison which I caught at the very last second before publishing, I am having laptop trouble though you're right about that
@falconcarwash435 thank you! I use Space Engine which is a Steam game. It is a virtual space simulator with a built-in screen recorder. I also use stock footage and Premiere Pro filters to make the images pop better. On Netflix and NatGeo, I can't see that happening any time soon! I like the freedom TH-cam gives me
I concur all.
@@sea_space I was going based off of your post that you had mentioned having rendering issues on earlier this week before releasing.
Thank you for clarifying, and thank you for responding, I'm like giddy that I actually got a direct response from you about literally ANYTHING! ☺️☺️
Honestly, you're my favorite cosmology or space stuff in general, channel.
I've literally replayed your videos hundreds of times to fall asleep, after watching a couple times intently, of course.
Same!
Hands down my favorite channel on YT, keep up the good work
Thank you so much and thank you for the generous donation
I'm a 1st my Hair does the same thing ⚛️🤖
@@1stHuemanAmericanwat?
so impressive how you changed your channel completely and became more popular rather than less. Cool to see how many people appreciate what you do. Though i really do miss how much of an impact you had on the geometry dash community, it will always be a distant memory
How was the channel originally. Im curious
@@sebastianmartinez5508he used to post probably the most interesting geometry dash videos which is a very simple game but had a very deep connection between the community with races to beat certain levels and feuds hackers and I think he used to be interested in that so he posted that type of stuff
A lot of twerking videos. My favorite was one titled "dis one 4 da bois"
@@sebastianmartinez5508 it was geometry dash documentary’s and other geometry dash videos
@@sebastianmartinez5508he was a good geometry dash TH-camr who made videos about news in the community and good documentaries on levels but his content is even better now and drama free.
You make absolutely fantastic content that I don't see many other channels equaling, much less surpassing. I am so glad that you haven't gone down the road of clickbaity titles/thumbnails and nothing-burger topics like Astrum has of late.
Please never change!
It is always SO exciting whenever you release a new video. I hope you continue making videos for years on end, as I genuinely do not know what I will do if you ever stop making new content. Your videos are not only educational but also very therapeutic as well. Thank you for all of your hard work and dedication!! ❤️
Lol you actually think this speculation based nonsense is “educational”? 😆
I bet ur an atheist… Lol
I got your reply last month , thanks for getting back with me! I have donated to other creators, but I’ve never got a reply from the creator themselves.
I know creators like yourself that do your caliber of content have to be extremely busy with fresh content so I get why the others didn’t reply to me.
Still, it was very cool so thank you!
When I can I’ll drop a donation.
I wish I could do more for a channel I frequent as much as your’s.
I’m an amateur astrophotographer and , what got me hook line and sinker was your video on M33 and of course M31 which really have no peers on TH-cam!
I’m not a big reader so if I want accurate information on the galaxies that I shoot there’s really almost nothing outside of a few five minute videos but they don’t break down different star forming regions of the galaxies like you do.
It’s really top-notch stuff man and although I can’t resolve individual stars unless one goes supernova like the one in M101 in May.
I can clearly see the star forming regions you talk about and it’s nice being able to put a name to the face so to speak.
Please don’t feel compelled to answer every comment in a donation I leave.
I’m sure you have more important things to do and I won’t take offense if you don’t.
Cheers!
Thank you for yet another incredibly generous donation! As you might be able to gage from the two quick fire replies I respond to lots of super thanks donations and messages in one go, and it fills me with joy to see you getting so much from the M33 and M31 videos. And likewise, please don’t feel compelled to donate often, your evidently unwavering viewership is equally as valuable and I hope you’ll continue to enjoy the channel 💙🙏
This is the best mother's day ever. Not because I'm a mom, but because SEA released a new video.
I was just watching one of your videos when I saw this upload! You make the best content, greatly appreciate the time & effort you put into your videos!!💛
So far this is the best space channel I've found here, and I've searched a lot. Thank you!
History Of The Universe as well as PBS Space Time are top tier as well.
@@WisdomEDM I agree, they're really good too.
@@WisdomEDM i understand nothing from pbs spacetime...
Will check out! My other favorite is Cool Worlds with David Kipping at Columbia University. ❤️
I found your channel around 4 years ago. I recommended it to every friend i know who is space interested. Now we all send each other your videos as soon as they are uploaded. Its like waiting for a new episode if your favorite show
I appreciate the time you take to make these videos. Absolutely incredible!
Your videos are always fascinating and perfectly narrated. I’m glad I’ve been a subscriber since you started these amazing space videos, truely grateful, thank you
I fully agree, but however, at times I have to use the closed captions to decipher some words he's slightly slurring due to his heavy, rich, English accent... even though I have English as native language in Canada.

I'm SO excited to watch this video! You, Astrum, Melody Sheep, Cool Worlds, John Michael Godier, V101 Space, and Science & Futurism with Issac Arthur are the pennacle of everything space related, in my opinion.
And if there's a channel that I haven't listed that someone knows about and loves, I'd love to be introduced to them, as well!
History of the Universe channel.

@@bipolarbear9917
Absolutely, though I can never stay awake long enough to finish a video of theirs. 😂
Vsauce is a classic
Sciencephile the AI is a great channel as well if you don't mind jokes and memes sprinkled in with your science.
Exactly the topic I was hoping you to cover! Love it!
Your editing has gotten insane, as someone who watched u in your geometry dash days I can say you’ve improved a lot!
Yes .. now i can drift off to sleep. And rewatch the last bit in the morning. Much love ❤
Always quality content!
Glad that you checked up on the article instead of just reshuffling the sources! I really valued that!
I remember watching the documentaries about a certain rythm game to sleep when I was younger, I still do the exact same to all of these videos every time a new ones released. Somehow I don’t think it’s the topic, I think it’s you that kept me coming back for so many years
There's no other channel on TH-cam that I get so excited about seeing a new release from!
You are the *FN* BEST at these videos SEA, please keep it going, your entire video catalogue is absolutely brilliant.
thank you! great video, as always! I'm gonna rewatch it several times for sure.
I got so excited when I saw a new upload from you! thank you for making these videos, they’re some of the best space videos on here
I actually get so excited when I hear you've got a new vid coming out! Black holes are also my favorite astronomical events, this was a great watch
It's always a good day when SEA uploads.
I recently just finished watching most of his videos, all the way down to the one about Clowns and now hes uploaded another video about Black Holes, im amazed i didnt find this channel earlier its so much fun to just sit back and enjoy simple but fascinating and long documentaries about space.
Thank you for yet another awesome presentation. From delivery to content and easily understood concepts and explanations. This is by far my favorite channel and I so appreciate your work. It rips my heart out the end when you say something we can never know. I mean unless we're rounding a billion years to see.
For someone who only graduated HS, Why am I so interested in this? You make it easy for me to understand it. I love all the quantum space stuff 😅
the level of **formal** education you have shouldn't EVER restrict you from learning about things that interest you, especially when it comes to videos like these, where immensely complicated topics are expertly explained in terms that really anyone with a basic understanding of science can easily understand!
Since į found this channel couple years ago never missed a single video. Great content as always. Keep it up!
Already watched this twice. This is so well put together. (not to sound weird, but also very calming)
Keep it up! Great content!
Just when you think you're the biggest, there's always someone out there that is bigger.
Again, the best channel on TH-cam. Outstanding work as usual
Finally, the only content worth watching has blessed us once again
I’m always looking forward to your videos. I absolutely love the way you narrate. Great job SEA. Keep up the great work.
My favourite YT channel. Lots of love from India, Kerala 🥰🥰
As was said at the end of the video, when you consider the fourth demension, TON 618 is more then likely the biggest we've seen, because we are only seeing it's baby pictures, over 10 billion years ago, and Phoenix A is already a teenager "only" 5 billion lights years away
But he clearly siad phoenix a's mass is not a part of any new discovery or measurement. It is an outdated speculation.
tbf given the nature of the theoretical limit its hard to imagine it would grow much larger with the info that we have
Here we go! Been waiting for this the the hole week 😂
As always, great video! I always can't wait for the next one!
I fucking love sea. Never stop making content.
I started binge watching your videos about a month ago. Super happy to see a new one!
Oh now this makes my day !! Thanks for all the great work ❤
It’s crazy seeing what you’re doing now, I’ve been watching since you made geometry dash videos and now that I enjoy topics about space I’m coming back to your channel
You've just made my Sunday afternoon!
SEA, you're better than crumpets and marmite (but only just)
SEA.. Great work. Your one of the best . !!! It's your ability of projecting an honest report regrading the fundamental topics of the cosmos. Everyone can feel your enthusiasm.
Always worth the wait for another video from SEA!
You do such a great job of story telling your episodes. Always a pleasure watching these.
Tommy Timpkins!
Man that was worth the wait! Best space channel ever!
Thanks for another great video, look forward to many more!
I love the whole topic of black holes! Currently working on a realtime render ^^
Thank you for an intensely interesting video mate. I always watch SEA videos with pleasure
Yo I’m struggling with sleep. your videos, helps my mind unwind and it helps with being able to fall asleep. Been watching your channel for a long time. Just wanted to say thank you!! Please continue make more content
WOO!!! Yet ANOTHER video from SEA! Love this channel so much ❣💯
Your videos are always a treat.
Dude, I have a 35 minute commute to and from college, making these videos literally perfect to listen to during the drive. Hope you keep making these!
Tonka Tokugawa!
thank you very much SEA, I can't believe the amazingly great content that you continue to put out
Worth the wait sir. Excellent work!
Great video though always enjoy watching your content past and present
I quit playing Geometry Dash almost 5 years ago and came back recently and... a lot has changed... I still remember back when you used to make GD news :D
So as a GD player and Space lover, your channel is goated
I can’t believe it’s been 4 years since I officially quit that content. Looking back that game gave me such a good buffer for future channel success. I see 2.2 still isn’t released 😳
@@sea_space Yeah that's wild lol
I hope you're doing well now with space content :)
I mean.... you are
@@sea_spaceI’m just glad that your channel has grown so much, I’ll always appreciate your GD vids but it is very clear how much your new direction was a great idea, keep up the great work!
Another banger Sam! Thanks for everything 🥰
Another SEA video! Time for a fantastic time. Thank you for all the effort
This is a fantastic break down for anyone new to learning about black holes. Thank you for this video.
Half an hour never passed so fast. I was glued to the screen in amazement of our incredible and scary universe. Shows us how much we still don't know, and how small we actually are. Beautiful video. ❤
What's preventing 2 40 billion black holes from merging?
The rarity, mostly. If we assume that on the large scale the universe is mostly the same, with only local degrees of randomness, then the likelihood of two 40 billion solar mass black holes forming close enough to one-another to collide in a 13.7 billion year timeframe is near-impossibly rare. Excluding Phoenix A and the Camelopardalis black hole for unreliability, we've found a grand total of four 40 billion solar mass black holes, a fifth which could be one with generous estimation, and if we assume Phoenix A and Camelopardalis to be at 40 billion, that would make seven. Five reliable estimations (seven including the unreliables). Going back to the relatively even distribution of matter in the universe at-scale, you would need an asymmetric region of space flooded with plasma in the early universe where two equally sized galaxies (as opposed to one incredibly massive one) would be formed, chiefly from the direct collapse of all of that gas. Supermassive black holes are rare enough as-is; don't forget that the observable universe is 93 billion light years in diameter, and we've found only FIVE of those boiz.
tl;dr: Big space empty, not enough time.
even after you stopped gd content i stayed watching. glad i did. i guess you could call this a god eater
Absolutely amazing video man!
When I invented black holes I never thought they’d get this popular. I really need to thank SEA and all of the other cosmology channels for promoting them.
Partner I agree! They will never understand what we did.
Superb, as always ❤
This video was right up my alley. Great video
You know it's a good day when it's a new SEA video day
I trust this channel. moreso than those astronomy click bait channels that make wild claims in the title or that the astronomical community has ditched the big bang. I trust SEA, Cool World Labs, Anton Petrov, and just a few others because sources are in description and you all absolutely care about accuracy - anyway thank you
I know what you mean. Best method to avoid trashy videos is skipping everything with sensational titles with words like “shocking” “mysterious “ “secret “ “unbelievable “ etc.
Fascinating in-depth content. Mind boggling!
Amazing channel. Subscribed.
I can't believe you have come such a long way, even after you quit gd (which i have nothing against) seeing how you completely turned around your channe while still keeping pooularity, it impresses me a lot! I dont know the exact story of when and how but thats still insane!
Another great watch!
Yo as a old gd watcher I can’t believe how far you’ve come! Keep it up
Listening to you is like listening to the voice of reason. Thanks for sharing this amazing content !
Can't wait to fall asleep to this
It's here!!! Thank you for what you do bro
Thank you we love you and your brilliant work
Just subscribed! I love this stuff
Amazing channel! Love it
"Unrendered space" is such a fantastic descriptor for an event horizon. I love it. Im stealing that.
This was an absolutely awesome and mind bending episode... thank you.
Everytime Sea releases a new video it feels like Christmas :)
Fabulous. _Happy to have found you!_
I'm gonna sleep so goddamn good.
SEA I swear to God if this is another joke about my mom I'm going to lose it
CHRISTIANITY is a JOKE
