whats your guys views on DMT?
@@Brazen1234I'm a Christian with a past and honestly if I were you I'd stay away from it, just because of the spiritual realm it puts you in. The last thing anyone needs is to open doors to demonic spirits to enter their life and it doesn't matter if your Christian or not, they will come after you.
@@daMillenialTrucker Go touch grass and let others be. Demonic spirits ffs, you live in the caves too?
Who else sleep to this?
zZzzzzz.... 😢
Makes for some awesome dreams as a bonus.

It‘s gibi or space stuff
I do, it's so relaxing
This channel literally aided me in getting off of drugs. Every one of your videos is so relaxing, every time I was sick with withdrawals, these videos helped me get at least that little bit of relief.
Thank you so much
Just wanted to wish you the very best on your journey. Sending you a ton of good vibes and strength for the road ahead. Be well my friend 🙏🏻
High praise. Hope you do well brother
I only watch this channel when on drugs
So strange! Because I usually watch this when I'm coming down and it's the most relaxing and grounding/humbling thing ever.
Keep it up. Best thing you could do for yourself. Withdrawls were a bitch.
Production, narrator, script, coziness, structure broken into chapters. This is THE best channel of it's kind on the platform. Same can be said for "History of the Earth" channel, ran by, presumably the same team.
They are the Best, aren't they?
Be well!
Yes, absolutely!!! I keep rewatching it and never get tired. Well, only if I let it play before sleeptime, but then it's intentional 😅 always serves the purpose, love the voice of the narrator. The most soothing voice, could listen for eternity.
@@fjc_adventures4359 No that is History Time if I'm not mistaken. History of the earth is the same creator as this.
This group and the channel SEA are the best when it comes to long narration cosmology content on YT
@@jmarth523Isaac Arthur is also amazing but he does like very sciencey, advanced sci-fi stuff but also super nice to listen to and very interesting
The quality of content on this channel is unbelievable. Having this for free is a gift!!! Thank you! Much love
This format has not yet hit the limit. I love how you're going deeper on topics we've briefly touched on in earlier videos. The production quality is stellar, as always too! One heck of a stack you're building, congrats on another one to you all!
Amazing. I have a Physics PhD and every single video of this chanell left me astonished. You guys do and incredible job linking all parts of the "universe jigsaw". You do it in a very elegant manner. Your videos about the universe are the best i've ever watched. And I've watched hundreads of videos and documentaries about it. My PHD wasn't in astrophysics, but I wish it was. But being an astrophysicist in Brazil is useless. But that doesn't mean I can't study it myself. And your videos have incredible visuals. Big fan!
Can you, as a physicist, say why we tend to discuss dark matter as a fact rather than as a temporary placeholder for an explanation of observations that don't fit our current theories? I find it baffling and a bit troubling that we seem to be going to great lengths to accommodate existing theory rather than questioning the completeness or adequacy of the theory to explain gravity on the very large scale. It seems to fly in the face of the scientific method. I do value your opinion. Thanks!
@@beenaplumber8379 Well, that's actually a problem in your understanding in the matter. I used to have this same argument for dark matter. It seemed like a guess. But it goes beyond that. Let's go to the facts. First, if you look at galaxies rotation speed, you'll notice they're spinning in a velocity that would just expel stars from the galaxy if you only consider the regular matter. So, actually, there must be "some substance" that is concentrated inside the galaxy perimeter, and that "something" has to have mass, and don't interact with regular matter through electromagnetism, only through gravity. And I know, it's not enough to jump to "dark matter". But all other possible explanations just failed to explain whats going on. And then they discovered the "bullet cluster", and that just raised, by a lot, the probability that Dark matter is real
The Bullet Cluster is composed of two clusters of galaxies that collided and moved past each other, though this is not clear when viewing the region solely in visible light. Multi-wavelength observations of the Bullet Cluster provided the first strong observational evidence that dark matter does not interact with normal matter, or with itself, and holds the majority of mass in a galaxy cluster. Astronomers use visible-light images to map the location of the clusters’ mass, based on how the light of background galaxies is warped. Most of that mass is dark matter. X-rays show that the majority of normal matter, in this case gas, is in a different location than the dark matter of each cluster-it lags behind. This is because the normal matter of the two galaxy clusters collided, while the dark matter sailed through and kept going without interacting at all. Many mysteries remain as to the nature of dark matter, and the Bullet Cluster provides key evidence in the scientific investigation.
They have a good candidate for dark matter now, and they're creating experiments to verify. It's very small size and mass particles, called AXIONS.
So, just search for some video about the "bullet cluster". I'm sure it will convince you too. Have a nice day, my friend.
@@ranyeredt Ooh that is an interesting observation. The center of mass moved along a trajectory as if the clusters hadn't collided, as viewed by lensing, but the ordinary matter (seen by x-ray detection) followed the path consistent with the collision, so the visible matter and the center of gravity became measurably separated? Yeah, that's compelling all right. I'll look that up. It's hard for me to imagine some poorly understood supergalactic-scale gravitational phenomenon that could become separated from the mass it supposedly arises from. But it's also weird that dark matter can give rise to its own gravity yet not be affected by gravity.
I read somewhere that dark matter was hypothesized to interact with itself by something other than gravitation, but it seems it has to be attracted to itself at some level in order to collapse into the filaments we see. I mean, dark matter is said to have collapsed and formed structure, then ordinary matter was drawn into that structure, right? Can dark matter still have this attraction to itself, only it's weaker than gravity?
Thanks for telling me about the bullet cluster. That's putting a few of the pieces together for me!
@@beenaplumber8379 Right? I felt the same when I studied this subject. Only then, things started make sense to me.
About dark matter interacting with itself, it hapens, but only through gravity. So, it doesn't collide. Recent theories, involving Axions and quantum mechanics puts dark matter in a fluid like behavior.
I really think we're on to something.
Another theory in 2022 argumented dark matter could also interact, besides gravity, with itself, but weakly. The first step now is try to detect the Axion. Let's see...
Interesting fact. Every single thing stated in this video is science-fiction. The real Hubble is actually mounted to a 747 and the top of the plane opens up. That’s a verifiable fact. Did you know they have a so-called clone Hubble mounted inside of a jet? NASA is a fraud organization that steals $70 million a day to show you CGI renderings and fake space art. We went to the moon on a paper machete shower curtain rod spaceship? But now we can’t go back? Answer from NASA. We destroyed that technology and it’s a painful process to build it back again lol. You would either have to not know or be a clown to believe anything that comes out of their lying mouth!
Undoubtedly, the BEST channel about Universe & Space on TH-cam. 😊😊
😊😊😊 Yes!
Well ladies and gents time to drop everything for the next hour.
I know y’all hear it a lot, but this series truly is phenomenal. I so look forward to new episodes. I enjoy all the usual suspects that most of us do on TH-cam, but y’all have separated yourselves from the pack. Thank you, sincerely.
I think you mean the next few days/weeks!! And then there's CERN!
I did my dissertation on this with Emma at UoN. Her book "First Light" is a fantastic read diving into the mystery of the dark ages and the problems we need to overcome to solve it. Great video!
That's fantastic! And Impressive! Thank you for sharing this. Be well 😊
No you didn't your not cool!!

graduating highschool today, this channel has got me through so much, entertained me on so many late nights and reminded me how lucky i am to get to be alive in a universe like this, it’s also reminded me that it’s all gonna be okay no matter what. thank you for your vids 🤍
Great comment!
Wishing you many good lucks 😊
Congrats 🫵🏽
The world is yours go get it!!!
Darkness and emptiness possesses light and energy, and nothing is static. In this lies hope for dark ages.
David Kelly is such a phenomenal old school oxfordian narrator. Hats off to you, sir🎩
Your channel is the only one I have truly liked out of thousands I've ever visited on TH-cam since 2008. Thanks from the bottom of my heart 🙏 You manage to send us into a thinking phase and an out of the world experience !
God created the universe.
The ONLY one out of thousands? 😳 Are you sure that you're looking at the right ones?
You must truly be a joy to know.
I suggest 3Blue1Brown, Epic History TV, Great Art Explained
@@ToughCookiez Prove it.
You (and your “holy book”)are stating a claim, not fact.
If you think otherwise, consider reading the definition of the word “fact”, OR the possibility that you are part of a religious cult that doesn’t allow critical thinking.
I just would like to say, that this channel has by-far the most polite and positive vibe I have ever seen. It restores a tiny portion of hope for our species overall. Lol thanks to everyone here and for the content creator for giving us all so much knowledge, in the most enjoyable yet very much a teaching/learning content. This is my fave of all science /physics Channel. Hats off for have such a wonderful ability to let people learn in such a calming and soothing possible way!
Yes - much of the commentary on TH-cam (elsewhere) seems to have been written by subhuman youths.
First time I comment, but the narration, the quality, the visuals.. everything you guys make is spectacular. The narration is professional, easy to listen to, yet the passion for the subject is palpable, ggs guys.
Dude I feel like I’m waiting for a new album to drop from my favorite artist It’ll take me a month to understand this video so by then there will be a new one. Love you man!
7:30 "Deep Field" is actually a 2D projection of a 4D image. The furthest objects are also removed from us further in time as well as in space.
And shouldn't they occupy a larger arc-area of our sky, relative to their actual size, than nearer objects because when they formed their size was relatively much larger compared to the (then smaller) universe as a whole? I know I read that somewhere about the most distant observable galaxies, but I've never seen it pointed out in an image, and the images in this vid don't seem to show it - not clearly anyway. The most distant galaxies are just clusters of pixels in these images.
Interesting fact. Every single thing stated in this video is science-fiction. The real Hubble is actually mounted to a 747 and the top of the plane opens up. That’s a verifiable fact.

Just wanted to thank you, again, for this channel and this magnificently produced series. Once again, I can experience the childlike wonder and awe I did as a child, when viewing the Cosmos series for the first time.
This is the single, best, most informative, interesting channel I have watched. I don't comment on anything. But this provides me with bitesize, easy to digest knowledge that I struggle to usually understand. Big thanks to the team here. I wish my skillset was more aligned with this. I would enjoy my job 😂
God created the universe.
@@ToughCookiez😂
This was my absolute favourite episode so far, and oh boy, I watched them all at least few times.
Absolutley amazing content, as always ❤
Oh joy, I'm so happy to see this! Watching it later tonight when I'm on my own and i can fully immerse myself in it. Thank you, thank you, your channel is the absolute best! I literally love you and your team for your fascinating content. ❤❤
Once again, HoTU made my weekend!
Thank you, (and welcome) Prof. Chapman and to Mr. Kelly for yet another of the Best Science Lectures ever created.
Absolutely outstanding content, produced and narrated in a way that is both comprehensive and easy to follow. Information is connected so there are no gaps in sequences, an so we don't end up with problematic holes in our understanding. This Channel produces some of the finest scientific content I've seen. Kudos to everyone that contributes to making it available. 👏
I absolutely love these documentaries, nothing on TV or the Interweb come close to the professional level of detail and production, as well as the way its broken down into easy to understand concepts for the laymen. Can't wait for the next one.
This is truly an outstanding series. I’ve always had an interest in what exists beyond our planet and the science that describes our universe and this channel does an amazing job of connecting the dots of knowledge. Thank you. Looking forward to much more.
Wow. You have already explained to me the entire history of the universe and concise clear and easy-to-understand terms incredible graphics, writing and narration there is no way you could come up with more content, much less make it anywhere near as good as what you've already done. And then you did it. Amazing I love this channel.
I watched all your videos and check everyday to see if there are any new ones! The quality of content here is amazing, the way you portray it in your videos is mesmerizing, it's as if I am reading a well written book.
I'm certain I've listened to this channel in my sleep 10X more than I've watched while awake. Of the awake watching, 95% is in the blissful transition that happens in between. Wouldn't have it any other way. His, is the voice that narrates my dreams.
Brainwashing you while you sleep is probably more effective for these videos made by intelligence agencies lol Brits do have relaxing voices that put normal people's minds in a relaxed state able to absorb information easily without question. Beware of that trick please. It's very real. Everyone in this world does not have your best intentions. Usually this much production has nefarious organizations behind it. JUST like television does. Question everything. Never just absorb. Especially while sleeping. It does affect you more than you realize that way.
i cant get tired of this narrator. just amazing.
This is what TDC and science channels used to be about. Its a shame this sort of information and science is not found on television any longer, and only seen on the internet. This channel is one of the best ive found, the wealth of knowledge within it is immense.
Hold up, did he just make the dopest Pokémon reference ever?! “Charizard” let’s gooo
here's a comment for the algorithm...fantastic channel! words cannot express my excitement when I get notification for a new HOTU or HOTE video
I can't wait till tonight! Going to listen the guts out of this!!!!
I absolutely love this series it is fascinating. My only problem is I listen to it at night right before bed, and the voice of the narrator is so soothing I fall asleep so I have to listen to it again in the morning.
Thank you HOTU i've been playing your videos on repeat i'm so glad to have some new material
The fact that everything was created in contrast can bring solutions more rapidly by putting the pieces together. So as the coming of the Resurrection can give better understanding of new creation under construction in continuity.
The music, the narration, the pictures, the story told, I am severely impressed how well these documentaries are done.
Somewhere between perfect for relaxing to sleep and not being able to sleep because I want to hear and see more :D
amazing as always !, this channel is a modern day discovery channel alternative,
heck maybe even better
New graphics, up to date physics and information. The chasm between HOTU and all other channels is vast. But how didyou come out with a new episode so soon after the double episode? You are amazing. 💯🌃🏆
Wow! What a stunning tribute to human ingenuity. Excellent video - one of the best I've seen so far. I think the most stunning part of all this is the ingenuity of the people who have designed and built the instrumentation allowing such detailed observations to be made, particularly when it comes to extremely weak signals. LIGO is another example and SQUID magnetometers yet another. I can't wait to see what comes next.

More *free* peak educational, scientific content!?! How is this allowed? Surely they have to charge for this level of quality? Right? Right??
"Close your eyes" as I'm driving on the freeway... Okay!
The further you go, the more you get mesmerized.
The more you dive deeper, the more you enlightened.
Universe is truly amazing ☺️
Another great video, and coincidentally very timely, as i had been discussing the topic of the "origin" of the universe (and time) in recent days.
Granted, it wasn't so much a debate than it was us voicing our own opinions about it, but this video is exactly in line with my thinking.
The "nothingness" isn't really nothing, it's just not something that we can understand right now, because we haven't observed it or recognized it yet.
I'm sure that during the period of "nothingness", there are actually all kinds of particle interactions, maybe a proto-weak force acting on particles and slowly shifting/organizing them into places where chain reactions can happen, and once that happens, then it's "light's ON and away we go!".
I've always held a belief that our visibility is blocked by some kind of redshifted "wall of light", kinda like noise cancelling headphones, our "winds" and forces block some photons, making things appear dark to us, it would be cool to see if a radio telescope in space might peer through that.
Looking forward to the next video!
Excellent writing Emma, really wonderful work. It is so vital in these days of trash science channels.
The best channel on TH-cam! How don't it is on TV like cosmos and this stuff?
All have been enjoyable, but this is my favorite so far. Please do more with how far back in time we can go and the cosmic web and filaments between galaxy clusters.
Absolutely love what you're doing here (even if you didn't actually tell us what is in the darkness, apart from Justin Hawkins) but keep doing what you're doing - for ever!
There's so many bunk channels out there making truly garbage "science content" for clicks, even downright lying, so forgive me for being a bit skeptical going into this, but you guys do really good work. It's a shame all those other channels are almost ruining it for ones like this when I come across them.
This is a popular demonstration of a history of all our universe, but supposing all our universe broke out at one point as a transformation of the primal Yelm (Gramov's Big Bang, ) this was our place in space. As we look out upon it, what we see will tend to be as old as we are. Even if we are traveling at c, the oldest we see will be pretty much what was to be seen when our dispersion hit the relative c.
That is, by the time consciousness arose, we would not see the original Big Bang. Nobody believes this. The cosmic background could be merely local black body radiation. Certainly local black body radiation must be a component of the background static..
Why does nobody believe this? Astronomers believe odder things.

It still seems crazy that im watching this on youtube for free..excellent job guys and gals! 🙏
this is one of the 2 channels I genuinely look forward to. thank you
I’ve heard BetterHelp is problematic.
I had a good experience
Imagine their religion for those who live in the void 🤔🤯
Probably not much different from us.. religion started long before astrophysics
Thank you for this series. I have NO desire to ever watch network TV again. Your videos are not just entertaining, but afterward , reflection about what I once knew about astronomy and how each installment has furthered my understanding is so rewarding to know what I just watched was not a silly waste of time. The idea that there is a web structure that facilitates the birth of stars is valuable information to me.
He could tell u anything in that state of mind & you'd believe it. Most of this is just theories. A british accent for some reason puts many people at ease to absorb information rather than question and test it. A weakness someone in intelligence might exploit. These are way too well done to be anything less. It's what they want you to think many times with some truths thrown in. This guy wants you to think we are all a simulation inside a Boltson brain FLOATING in the universe. And that THAT is more likely than humans (or animals) evolving brains inside bodies. QUACKERY. Anything else I can't take seriously after that. It's interesting to argue with though. Amazing people don't see this channel for what it is. Entertainment but at your digression, brainwashing. Many of the answers are just God. Like the creation of the universe they can't figure out. And we know it's actually 26 B years old now. They were wrong the whole time ICYMI. Recent news. I guess guy has to update ALL of his videos now. Not much different that TV does "programming". Just be careful. Good & bad stuff in here. MOSTLY theory. God bless!
What an incredible documentary. Your documentary makes me feel grateful to be alive so that I can understand some small part of the beauty and the majesty of our universe. And my appreciation for those who love our universe grows as well. The universe feels magical. Thank you.
i have never been so amazed by the quality of a youtube video, keep up the good work!
This channel is wonderful, you satisfy my immense curiosity, answer questions I've had and guide me in understanding so many fascinating things about this unimaginably large universe we inhabit. I love the narration and history I learn as well, keep up the terrific work.
this may very well be my favorite channel. Absolutely love your teams work
I love this channel. It's amazing how the universe formed (at least what is known so far). There's still so much to find.
Can't wait to watch this 10 times
Learned and re-learned so much here, many thanks.
Absolutely perfect content! Thank you for making all of your videos.
A visual and narrative poetic journey into our world. Love it.
I'm in awe of this channel and always inspired by the videos to think about the universe now in different ways
Perfect timing, was just about to start my nap!
Absolutely brilliant documentaries, I really enjoy and appreciate all the work you guys do. Thank you so much for sharing!
One of the best videos on Astronomy. This channel is another gem after SEA. Kudos to brilliant well researched work and explanation
I absolutely loved this. I've watched National Geographic, Discovery Channel and more without really understanding. You made this super easy to get, and took your time explaining how we can see back in time using color. Aga8n. Amazing stuff.
The Emptiest, Dimmest and Darkest parts of the Universe were the dressing rooms at CBGB's in 1977.
Really well put together run through. Thank you.
Beautifully narrated and fascinating subject. I love it..
Its like looking through a thick fog. Need to be careful to not see phantoms or spots in your own eyes or instruments. Where we came from and how it all came to be as we see it now is such a fascinating subject. Thank you for the excellent video.
Learned something new and learned about it thoroughly, thank you
Thank you for highlighting this very specific topic! Interesting!
These are some of the most wonderful documentaries on TH-cam.
Clearly one of the most beautiful scientific videos ever produced! I learned more about the advances of cosmology from this video than I have any other source in the past 50 years. WELL DONE!!!
My favorite channel! I just can’t wait until tonight now. Thank you!
What a stellar work only surpassed by the depth of a fascinating topic. Wholehearted thanks ❤
Your sponsor is the first time I have seen this type of wholesome advice. Well done!
If we lived in a void and our telescopes saw nothing, we would never bother to build better telescopes, and never learn there's stuff out there
Loving the longer videos btw man!
I am so excited to watch this it's been awhile since the last upload and I just love these documenterys so informative really inspiring very interesting your take on these events are astonishing very factual your information on so many variations of the Cosmo's it's immense 💯💥 thank you ever so much for your time and dedication to your amazing channel 🙏❤
Just love this channel and even more this guy! Thanks for all the work you do
Honey wake up, new HOTU just dropped!!!
Idk how this channel doesn't have over a million subs I really don't know
Great job! Thanks for making it understandable for laypeople ❤
I absolutely love these videos! Makes me happy to see an upload from this channel for my morning before work B)
As always topnotch quality. Easily my favourite channel together with Cool Worlds. Thanks a lot for this great video.
New to this channel, having just watched "hidden in the darkness", i instantly liked and subscribed. Factual, informative, great graphics and brilliant explanations means i am going to be watching more👍
Wonderful exposition. Thank you!
Just watch and lessen to your video twice and I will a third time... So dense so easy to understand but so much to digest. Thank you for opening new perspectives with all these informations. Thank you to make us understand more about our environment. Must work on a french translation as I could ask my friends to watch it. Thanks very much for your work and sharing to us. Namasté
So good, I regularly pitch this channel to friends and people I meet out. Do you know how awkward it is telling people to follow a TH-cam channel? It’s that well done. Other humans should know
I'm excited to watch this tonight!
23:54 The 21cm hydrogen line is in the UHF, or ultra high frequency, range. Radio astronomers may call it the L band (for long). 'Low frequency' would be 30-300 kHz, with wavelengths of 10 to 1 kilometers, respectively. Engagement correction lol
I will never get over the fact that hubble has astigmatism and needs space engineering equivalent of corrective glasses
😂
The therapy sponsorship is too spot on, they know their audience.
This series and PBS Spacetime are my goto for this type of content. If you love HOTU and need something to watch between episodes i urge you to give PBS Spacetime a watch, Mat covers a very wide range of GR and QFT topics. Love this channel and all its topics, keep up the awesome work.
Absolutely amazing content on this channel. Thank you very much!
I can't wait to get out of work to watch this!
