4800 stars are born in our observable universe per second, not Milky Way, and the amount of blood pumped around the body is per minute. Hope you caught those!

The quality of these videos is as staggering as the scale of the universe. You are setting an unbelievable standard, keep up the good work!
technically it can't be, since it is part of the universe itself. so it must always be smaller. 😂💙
Naaah. The videos are waaay too slow. It took them 5 minutes only for the introduction.
@@darkmetaOFFICIAL oh No.. NP completeness at works again
He certainly makes it look and sound good making the quality appear quite excellent... except for when he makes wildly incorrect assertions such as "'4,800 new stars are born in the Milky Way' per second." This is not even remotely close to being accurate -- in fact, it probably couldn't be much further from the truth. "Star formation within the Milky Way currently involves about 4 solar masses of gas condensing into stars each year. Since the average star is less massive than the Sun, astronomers believe the Milky Way is producing roughly 7 stars per year ." -NASA
Except it's estimated to be 4800 stars born per second throughout the entire universe, not in just the milky way. I just started watching and noticed that.
The fact the universe is only 13.8 billion years old makes me feel like we are so early in this whole thing. The future for the universe is an insane thought
i have a feeling that with the web telescope that number will change
I have 13.8k subscribers, it's as if the age of the universe is in my hands.
In the occult they say the Universe is within us, but this is ridiculous.
You don't understand the size of a billion then. The difference in 1 million and 1 billion is like the difference in $1 and $1000. If a lifetime was 100 years then you would have to live 10 million lives to live 1 billion years. Now multiply that by 13.8
@@ReyZar666 I think you mean "more precise".
@@EsotericBibleSecrets You're a few decimal places off. You would also have to have twice as many subscribers as there are people alive.
This video is exactly what I have been wanting for a while: a description of the very early universe with as much detail as we have knowledge. The narration, visuals, and music are well combined to produce a relaxing documentary packed with so much substance that I have watched it several times to digest it fully. I look forward to watching the rest of your video library and seeing new ones in the future.
its kind of amazing that this channel just puts out like documentaries every week or so
The way you read the the well written text, makes it sound like poetry. The (at times mesmerizing )images match beautyfully. The added sound/music very subtle underline the flow of the narrative. It all sums up to an extraordinary experience. So proven, time is relative, every second counts and should have the attention given in this video ♥️
Well said!
I ..second.. this
@@0kedoke nice lol
@@3nthamornin lol thanks -yung gawd
Nicely put, i totally agree with you, his narration is hypnotic, which makes the explanation of the facts very easy to follow for even a dim wit such as I, !!!
This is an incredible documentary. I was worried that it would be similar to the drivel made by the channel "Ridddle", who just makes claims & tells stories without citing anything. I'm very happy to have been proven wrong. Massive props to Leila. The way you weaved these stories is fantastic. Painting pictures of not only what we know, but *how* they were discovered. The road to scientific knowledge is long and arduous, and I loved to hear more about how we know what we know.
I'd also like to say that you managed to make this so easy to understand, yet not too dumbed down. I already knew a lot of this stuff from PBS Space Time, but still learned a lot from watching this documentary.
Thanks! What a lovely couple of comments. Exactly the aim of the channel.
@@HistoryoftheUniverse 😁
Yeah that other channel is just word salad..These guys are NOVA quality.. History of the Earth is just as good
@@gzhshsgdhhshs I'm joining you in your choice of words.
The sun loses a million tons of its mass every second?!? Like 34 seconds in and my mind is blown already. I love this channel.
*around 100 mil ton of hydrogen is turned into 95 mil ton of Helium. So its more like 5 mil ton of matter every second. But yeah its mind bending
Especially to think how little it actually effects the sun… unless you look extremely long term!
The video is wrong and it's actually 6 million tons per second. If it was only 1 million tons, we would all freeze to death. Every second, the sun converts 659 million tons of hydrogen into 653 million tons of helium and 6 million tons worth of heat and neutrinos. Of that, about 2 kilograms per second hits the Earth.
@@insanekos1 think he meant mass loss from the surface not mass loss through conversion to energy in its core (which it doesn’t lose right away).
Completely false. How much mass does a fluorescent bulb lose?
These dopes are just making this up folks. How do they measure the mass of the sun?
I rarely comment on any UA-cam video, but I couldn't help it here. Your video is like the Neutrino star which you explained in your videos .. because the video itself is so densely packed with substantial contents having a massive mass 😊 If I miss 1 minute in your video, I feel like I have missed a great deal and I replay it paying attention to every second .. which also emphasizes the importance of "One second".
Everything about your videos are amazing, the vocabularies you choose, the way you pronounce, the perfectly synchronized authentic images and videos, the soothing music in the background. It's past midnight now in Germany in the middle of a working week, that explains how much I love watching your videos! 🤩
DO NOT CHANGE THE NARRATOR...EVER!!!!
This whole series is amazing. Deep yet understandable. Both the writing and the presentation are excellent. My favorite UA-cam channel.
Agree ..Best Channel ..Guys are so talented
Well they are not understandable for me.
On social media people are raving about ppl who give away things like a watch or money or cell phone to ppl in need.
But someone creating videos of this quality and accuracy....is significantly more valuable and amazing. I am really grateful for this 🙏 🙌. And to think that these are not 1 minute shorts they are 1-2 hour videos.
It also restores my faith in humanity when I see millions of views on these videos 😊. So not everyone is just watching brawls and prank videos all day everyday.
I can only imagine the amount of time and effort that have been put into making these videos! Awesome narrative, awesome visuals, awesome everything! Thank for this!!
I mean, yeah, him and his team. This ain't a one man show.
I'm looking forward to the sequel where we'll look at the second second of the universe.
Educational videos like this are what make the internet a fantastic resource for learning and "History of the Universe" is among the very best on offer, I am 69yrs old now and the internet makes lifelong learning to feed my insatiable curiosity possible!
I can barely get my brain around algebra but for some reason I am endlessly enthralled by this. Great work.
Great video!
One small correction: I guess the number of 4800 stars born refers to the entire visible universe rather than the Milky Way where "only" in the order of 10 stars are produced every year.
My thoughts exactly. Was thinking hang on just one second...
Guys he's on about what happens in 1 second!! Remember there's between 100-400 billion stars in our Milky Way Galaxy!!! Huge discrepancy i no but having that many stars being born and dying in one second doesn't sound too much in my estimation!!?!!
@@simonmcgrath4112 While these numbers are beyond imagination one can make a rough estimate. 4800 stars a second and roughly 30 milion seconds a year would amount to a yearly current star formation rate of roughly 150 billion stars per year.
On the other hand, assuming the current star formation rate constant over time would lead to a too low result (by one to two orders of magnitude). So there have been episodes of more active star formation.
Guys, I'm a bell end!!! I've read his prologue and the young lads reply and it says......4800 stars in The Observable Universe not what i spouted out!!! Never to old or too much of a man to admit a mistake!! I cud have deleted it but I'll take it on the old Gunga Din!! (Just made that up, good eh?!!! Maybe not then!!?!
@@simonmcgrath4112 No problem at all. It is really easy to get the numbers not entirely right when dealing with large-scale astronomy. Sometimes it is even hard for professional astronomers.
Insanely great video, from the narration to the soundtrack. Everything is presented so well. Thank you for quality over quantity homies!
soooo good, i love these too ESPECIALLY when done Pro, such as this!👽💯✌
quality AND quantity. 45 minutes of excellence

Your content captures the imagination like nothing else I can find on UA-cam. Thank you for committing your time and effort to making this so interesting and consumable for a curious observer.
It's crazy how he's so good with reading scritps, writing them, and then even edit it all with animations and music etc. This dude is just crazy good!
The opening One second is near an eternity in the Big Bang.
Even cosmic inflation had ended by 10^-32 seconds.

1 second in, 13.8 Billion years to go...
Gonna be a Long series. 💖
Lol. Good point!
@@vhawk1951kl first, he's quoting the name of the video, so he's fine. Second, everyone understands he's speaking colloquially. It would be almost as presumptuous as your comment for him to write: "History of the [Multiverse] (sic)" now shouldn't it... clown.
I've loved every second of this series.
I'll see myself out now...
A series on the entire history of the universe and we've only reached 1 second haha
That first second was pretty bonkers
@@HistoryoftheUniverse If the next episode covered the following 2 seconds, the one after that 4 and so on, about half way through episode 59 we'd up to the present. 😀
At the end of this captivating piece, the narrator asked to comment an let you know what I think about it.
In a word, "MAGNIFICENT".
Thanks so very much. 👏🏻
Like any other in the series, quality documentary. For me right up there with Attenborough!
But Attenborough is a proven fraud.
I know 99% of the information that comes out in these videos, but the production quality and storytelling is so good I listen to every single one. Thank you
A couple of questions:
Was the matter that expanded during the first zeptoseconds subject to relativistic effects?
If all of the fundamental forces were basically the same but then separated as the universe cooled, could that mean that other fundamental forces will appear as the universe expands even more?
that is a interesting question
Great question and well put might I add 👍
Apparently yes... I remember reading somewhere that electromagnetic fields were apparently not a thing for 300,000 years after the birth of the universe. They only started appearing after 350,000 or so years.
If you read up on the Planck Era and the eras that come after it, I think you will have better understanding of what we know about the appearance of the all the fundamental forces of nature.
@@smrutismarak9503 Cool, thanks!
This is by far the best channel on the topic of the Unvierse. Please keep putting out such great content!
I feel like I’m one of the few people that doesn’t put a special emphasis on the “fine tuned” constants of the universe. We have no credible evidence to suggest that if the constants were different that complexity & chemistry would be somehow dead & lifeless for the eternal future. Rather than taking a route to some unknown physics & alien chemistry. Some people would call that crazy but what’s more crazy is assuming that some deterministic metaphysical law spits out infinite universes ( most of them being mysteriously dead ) or some deterministic deity that’s outside space/time somehow computes this one universe to be this way etc. We don’t know what particles ( in the most fundamental sense ) are or how the constants evolved to give us our emergent & complex 4d spacetime much less the ontological notion that this spacetime is the only possible value that could give rise to many body complex systems.
wrong way round. life arose within the confines of the constants.
That's a similar way to how I see it. If the physical constants were different in a different universe than any intelligent life that may have arisen there could also say that their physical constants are also "fine tuned" to allow for life to evolve, although maybe I'm looking at it from the wrong perspective.
@@markgallagher5908 No you’re definitely on the right trial our “fine tuning problem”. isn’t a problem at all mainly just a distorted perspective, tbh I don’t understand why it got mainstream as significant in the first place. 🤷♀️
@@kw8274 i agree that a singular deterministic will driving the vast, boundless enormity of existence is equally as implausible as such enormity being largely outwardly recursive as a manifestation of deterministic math. your assertion is that the way things are now are not necessarily prerequisite for equal or greater total system complexity; humans are bound by the inexorable grip of perceptual geocentrism, and our logic demands a linear progression of ideas that proves cumbersome in truly out-of-the-box thinking.
i'm sure if I understood more about the emergent properties of space-time and the topological manifolds which define it, i'd be able to offer a useful commentary, but in lieu of that I'll just restate what you said slightly differently so it looks like i offered a novel idea... i mean, uh, well, consider this: what you're saying here is fundamentally no different than what the so-called "many worlds hypothesis" proponents are suggesting, except you're taking in a different direction. rather than imply that quantum events diverge such that infinite sets of universe-states can be generated from any singular "waveform collapse", there are infinite "waveform collapses" that can generate a singular universe-state. the distinction is subtle, but basically what I'm implying is that instead of starting with x=0 and iterating incrementally, we take vaguely determined parameters like "complex life" and suppose that any number of miniscule gluon nudges and cosmological constant shifts might lead us to achieving those parameters, but in ways we couldn't feasibly comprehend due to the bias of our limited human perception.
when you're discussing abstractions like the intricacies of multiple universes and time-line bifurcations, you might as well double down and get REAL weird with it, in my opinion. it seems that determinism is the kicker here, isn't it? this is a question of such dubious importance and quizzical complexity, we've been arguing about it for as long as there were two humans with separate philosophies to argue it with. if you think i've perceived your intentions correctly, i'd like to tempt you with one last morsel of speculation, presumably one you'd like to respond to in turn. what if this ephemeral teleology that haunts our collective consciousness is, in fact, as real as any fundamental force but rather than being the will of a singular all-too-human architect-consciousness or the unerring procession of causality as determined by an ontological pinball game set into motion at the big-bang, what if both were true? what if determinism's practical manifestation in our observable cosmos is an illusion of a greater phenomenon, namely, that of the whistling arc of the Arrow of Time whose fletching is causality and whose head is meaning itself. a teleological warhead propagating throughout the boundless medium of creation that folds so much interconnectedness and relational information in on itself that a mass-accretion disk of complexity tugs on the past and future with equal intensity; a determinism whose inevitability is precise and methodical, but impersonal and excessively iterant only in that it is equally individual for every energy transfer that occurs along every field-line in every plane of reference and in every moment in time.
Your narration have the same feeling as the "how it's made" show that ran on discovery 10 years ago. Soothing voice, great pace, amazing script, all around high quality.
It's so sad that channels like this one have so few subscribers and get so few views. Imo, these channels are the best thing on this platform.
The mind boggles. Thanks to Leila Battison and David Kelly, for another awe inspiring and breathtaking video that made me cry!
One of the few channels I actually get so excited for when a new video is released. Incredible stuff!
What happened at the big bang is one of those questions that even cosmologists kinda skim over whilst saying there was nothing we could understand (as there was no time) but this is the BEST explanation that not only makes sense....but it's done in e wwy that even I can ALMOST understand the forces and principles of the universe when it was even less than a billionth of a second old....Amazingly explained ,scientific premise,and a truly beautifuly crafted educational video guys.👌🏽
I can’t help but ask what if the universe isn’t expanding? I’m in no way a scientist, just a cosmic enthusiast at best so this is just conjecture from an ape. Thinking about the void we’re floating in expanding just seems…. Preposterous
The best explanation to "what was at the big bang" is "no idea, physics doesn't work at that point"
"A lot can happen in one second. But is it enough time to build a universe."
*Isaac Arthur comes crashing through a wall*
I really like that this video is not rushed. I love that you took care to tell us what needed to be told with time for wonder to sink in.
The Absolute Best scientific description I have ever heard of the beginning.
Superb narration and video.
The food of thought. Thank you.
I would think that in the neutron-lighter universe described around minute 42-43, the whole "No stars" thing seems a bit of a stretch. Wouldn't stars simply begin with triple alpha, if they don't have deuterium to fuse? The smallest viable size for a star would be larger than in our universe, red dwarfs which would stop fusion before beginning triple alpha would be brown dwarfs, but fusion and stars should still be possible in such a universe.
I was thinking about that too.
What I realized though, was that helium fusion basically marks the end of the main series lifetime for a star. They expand and depending on mass may fuse several different additional elements after helium, but the time a star has left is very short by comparison to its lifetime while fusing hydrogen.
So any stars that formed would basically be end of lifetime giants and likely die out after only a few million years
The whole "heavier proton" thing is where this video went off the rails for me. A neutron is basically a proton + an electron with some mass lost as binding energy. For protons to be heavier than neutrons would require different quarks and thus entirely different physics. There's no way to predict what would come from that.
The numbers are staggering.
My hat goes off to the men and women who first wrestled with the maths that have revealed the actual origins of cosmos in such a definitive way.
I absolutely love your balance between informative teaching and mesmerising poetry
Yes! A new video! These are absolutely the best written and researched videos I've come across.
This has to be the best series and channel I've seen in years. Thank you for your wonderful work in explaining the Universe!
Every element of creativity in this series is perfection.
The music. The animations. The editing. And now we arrive at the brilliance! The Script and spectacular Narration ( there are no credits listed amywhere for whom he is).
There is certainly no science series that equal to "History of the Universe". Please. Please create additional episodes! All Best Wishes from New York.
It's me! Thanks Art, very kind.
Excellent video. All the things that happened in a second at the beginning of time, and people get upset if they are running 5 minutes late to work 😮
Thanks for producing such fantastic, top quality content. You're narration skills are world class. You know I often listen to your videos while drifting off to sleep, it makes for a weirdly intimate relationship haha. Thanks for putting in all the hard work to make these videos, it's very much appreciated! Always looking forward to the next one :)
Every night I let the playlist of all vids run in the background to sleep, it's just too calming
These are the best documentaries I've ever watched. The only thing wrong with them is that I am almost done watching them.
I guess I'll just start over.
Thank you for your videos.
This video is a superb production, a great story told in a great way, an epic worth rewatching over and over.
It's intriguing (at least to me) that in the 2nd and 3rd generations of quarks (Charm/Strange, Top/Bottom) the positively charged quarks are the most massive, in the 1st generation, the Up quark is "lighter" than the Down. Is this just part of the happy accident that makes protons stable, or is it something deeper?
Also, really terrific video!
Nobody knows why this is how it is. It just is. Depending on who you ask, this may or may not be a real problem with a real explanation. It depends on your philosophical perspective on the role of science.
@@davidhand9721 Yes, it's very nearly pointless to ask Physics "Why?" when it mostly answers only "What?" and "How?" But this particular asymmetry might hint at something non-philosophical. Same with the left-handedness of the weak force.
@@davidklang8174 The P symmetry violation is another big hint, yes. It almost necessitates a geometric approach to the weak force. There's a spatial component to it.
@@davidhand9721 Spatial, perhaps. But in how many dimensions? I'm a bit of a 4D chauvinist, but at least the time component seems critical. The weak force can pluck matter or antimatter from the vacuum as needed (given available energy) to conserve charge and spin. And what's up with the Z? Symmetry breaking in flavor-changing currents seems absolute, but the weak neutral currents, though ambidextrous, are still preferentially left-handed. What does that hint at I wonder?
0:34 Surely u mean 4800 new stars are born in the observable universe?
Yes! A mix up. Thanks Big Dave
I think that number plays some concepts.
hey I just wanted to say this video was great. I think it was the best of your videos I have viewed so far. Looking forward to watching more older ones and seeing those you create int he future.
This is an exceptionally well done video. It deserves far more views than it currently has. Great job!
As usual an insanely great movie. perfect mix of storytelling and science.
Regarding the first seconds, I always wondered about the influence of gravity and speed on time at this scales. Isn't the time supposed to slow down hence this first second would have seem much much slower from the participants point of view ?
"On average, our hearts beat 1.3 times"
Mine has definately besten more than that.
Then you are above the average!
lol i noticed this as well
Most underrated science Channel
I was just scrolling through this channel and was thinking a new video should be coming soon, my prayers have been answered! Great content. 👍👍👍
To an outside observer, Time passes slower as something approaches a large gravity field. At a sufficiently large gravity field (eg, the event horizon of a black hole), time stops completely. Likewise, time slows as an object's speed approaches the speed of light. Therefore, time isn't uniform throughout the universe -- it depends on velocity through the surrounding gravity field.
Ie a black hole visible through a telescope for, say, 14 billion years was created just a few minutes ago according to clocks orbiting at the event horizon.
How can one conceive of a "universe one second old" when time has stopped?
Perhaps that's a good way of looking at it, to compare the time in a black hole to the time in the big bang. It could be an infinite amount of time until this whole process completed and time "began" as normal again.
@@vhawk1951kl All models of the "creation of the universe" are from the viewpoint of an imaginary viewer, outside the system -- the Genesis story, the Big Bang, Time Chaos, etc. The intent of using an imaginary viewer is to comprehend the unimaginable, to allow words to describe a system that precludes existence.
Helium still fuses at the hearts of massive stars
Your channels and videos are legitimate masterpieces… all of them, each and every second. I love your channel.
Oh man this is so incredible thank you I usually put these things on to like fall asleep to you cuz the narrators are so nice and just thinking about the Infinity of the universe just allows my brain to soar but this one has me up my brain is so active right now thank you I never realized how much took place in one second
When i die... And i get to become a ghost... I would then like to explore the galaxy... I just hope i can fly though... Its weird thinking about death and what is possible beyond it, are we still bound to the science of the living, or are we free from the current physical constraints we live in? I wonder, what my passed on siblings are experiencing right now... Is it just nothingness or do they get to witness phenomenas beyond or intellectual understanding? Hmmm
Yeah not going to happen. It'll be exactly like before you were born. Nothing.
It's incredible the production value we get for literally free thank you for doing what you do
Yeah agreed, great production values but its not exactly "literally free". You're getting advertised at, and he and his team are making those sweet sweet dollars from it. That's how the last 90 years of TV broadcasts have worked.
This channel is so great. So informative with no ads. Just awesome!
The editing and overall quality of these videos are great. Just starting my channel and enjoy seeing guys who make objectively good videos. Something I’ll be striving for
Wish you all the best
Love this content. I have a question about a statement that a universe of neutrons and helium would be cold and boring. Surely helium stars would ignite. They would have to be more massive so there would be fewer of them, and they would die sooner. But some of them would still go nova or supernova and they would get there faster. So there would still be heavier elements, but a lot less and a lot sooner.
Thought the exact same thing
Plus later stars would be much rarer. They would need more mass to ignite. It wouldn't be an issue to create heavier elements and have them decay back into helium, but hydrogen would stay incredibly rare.
An incredibly well crafted presentation. Proof that there is truly valuable content here on the 'tube.
This is all supposition , it can't be proved . Besides time is relative
Everything on this channel and the sister channel about the earth are masterful works of art. Miles beyond anything I've ever caught on any tv network
8500 pyramids of Giza in a teaspoon… that’s absolutely incomprehensible and yet we still have problems with the topic of “are we alone in the universe?”
I 💘 thinking about how time dilation worked in the extreme gravity well that was our universe in the 1st "second" as we think of one. A Plaunk length of time would have been a near eternity to an outside observer
Congratulations ,your the only person (except me) well to be fair I haven't read every single comment , anyway as you say it was a different time scale back then actually time was not even in existence so cannot be measured grrrr.
Very likely the best episode yet. I never tire of these videos and watch them over and over again. Absolutely brilliant.
I love this and these videos series. Amazing channel find. Hope many more find this work of art. Love the narration, music, images and content. Love its length too. Love it, thanks.
To watch any of the videos on this channel and not feel the need to subscribe just seems so unjust. All of these videos are excellently narrated, written, edited and delivered concisely with engrossing graphics. This is what the internet was invented for. Thank you.
00:34 That number seemed improbable. And in fact it is 4800 new stars every second in the entire observable universe, not the Milky Way. The data for our Galaxy indicates on average between 1 and 7 new stars per year. That is quite a bit less.
👍
Simple Google search will prove this right with plenty of evidence how and use the copernican principle ourselves our planet our galaxy should be just one indistinguishable dot among billions upon billions of dots the universe is massive beyond what our brains can even begin to understand
@@benward837 "will prove this right" - what do you mean by "this"? My comment or the video? Because if you google this fact, it will tell you the number 4800 stars per second was calculated for the entire universe, not just the Milky Way.

So there are more zeptoseconds in one seconds than there are seconds in the entire history of the Universe. Just like there are more planck lengths in 1 m3 than there are m3's in the known Universe. My head is mashed. Good morning Sun
Hands down, best universe origin story I’ve come across. Immediate subscribe and like!
Amazing documentary, i can watch stuff like this all day long, keep up the awesome content
Love your videos! Appreciate them even more knowing they come from a fellow Spaniard
Not actually Spanish (I wish!) but I do live here. HOLA!
Also great, hope you enjoy it here!
I don't think that's correct that the milky way has 4800 born per second. Thats around 150billion a year and the milky way would be the most massive galaxy in all the universe. I believe that number is the universe as a whole with 4800 born per second and 150billion born throught all galaxies. I don't know how many the milky way produces a year but I thought it was less than 40
You, Sir deserve sooo much more followers. Incredible stuff. Keep on, its a real gem in this UA-cam world
Truly the best astronomy channel on UA-cam. Beautifully written and narrated. Thank you.
The universe has never been one second old.. And here is why..
People have a very poor understanding of what the word 'infinite' actually means.. This is not any kind of 'fault', but just that we have evolved within the confines of what appears to be a finite environment, and we thus try to look at things in finite ways, also justifying those 'finite' thoughts. When I first approached the 'problem' I had the same difficulties, so it takes our minds a lot of effort to reach another level of understanding, but it IS achievable..
Firstly, there cannot be more than one 'instance' of infinitude, otherwise a secondary 'thing' would render them both 'finite'. So we are describing a 'oneness'.. Also, it can have no 'beginning' nor 'ending' as these would also necessitate a secondary 'thing' (or the utter nonsense of a 'nothing'!). Then, we have to admit that it can only be the one thing that interconnects all other 'things', and we deduce this to be 'Space', necessarily..
All references to 'size' or 'direction' do not apply to the nature of infinitude, and thus have no relevance to our understanding of the true nature of existence. 'Measurement' has limitations, so we cannot understand the true infinite nature of existence simply by measuring it....
If so much can happen in one second that takes 45 minutes to recount in a video, how are we going to deal with the societal spacetime of humanity? What tools ⚒️ technologies and methods would we need to portray? I am totally 💯 freaking out!!
Fascinating. So well presented. I learned so much. Thank you!
This video is one of the best videos I’ve ever watched on youtube, the narration is very soothing, the visuals are immersive and the flow of content was super engaging.
Excellent, beautifully presented and narrated informative video. Was great to find out how and why Helium is so abundant due to the mass differences of the proton and neutron. Never had that explained before. Thank you.
Love this channel
Wow, simply incredible!
I put this on last night to fall asleep, and put it back on right when I woke up. I didn’t want to miss a second of it!!
What a fantastic video, I really like how your humour comes through in little ways, this channel is incredible 💪
Great channel I really enjoy the content and the narration of this and your sister channel. Please keep up the outstanding work. This is one of the few channel that actively look forwards to new content...
Awesome channel with awesome content. 🌍💯💖
Excellent ! I didn’t understand a thing, but I still find this presentation most captivating. .
man thanks so much for this new video!
love your docos!
keep up the good work!
Yet another brilliant episode in this awesome Universe series! Thanks!=)
Yeah fake news, buddy 🙄
@@blokin5039 What u talkin about..!?🤨
If nothing ever goes faster than the speed of light, how could the universe expand 20 light years in its first second of existence?
Nothing ever goes faster than the speed of light through space-time. However, that speed limit does not apply to the expansion of space-time itself. That's how warp drives might work one day.
This was the point at which I paused, and replayed it! So from answer below: yes space-time itself can move many times faster than paper of light! Not heard that one before.
The ELT or Extremely Large Telescope being built in Chile will exceed what JWST will be able to see except possibly some infrared wavelengths. It should be finished in 2023, but Covid set it back at least a year.
Exquisite!
Fabulous graphics, presentation and narration....a Work of Art...Please keep them coming...Fast and Furious!
I feel like I can never get enough of this channel
