I'm not sure if this is a compliment, but I find listening to your videos whilst I'm falling asleep extremely soothing. I have very severe anxiety disorder and this helps me a lot, Thanks for your content.
Can I just say how much I love this channel? I use it for three things mainly: 1) Learn or at least hear what I've already learned from a unique perspective 2) Fall asleep and 3) Wonder in awe of it all. I do 1 and 3 together when I first watch it. Then I get an old video and do 2 and 3 together. Some people get the existential creeps from cosmology. It only makes me feel more centered and serene. Thanks for the amazing videos :)
Your channel BY FAR has the most interesting videos on cosmology and quantum physics. I’ve been watching for a few years now and I’m always just as excited when a new video comes out. Thank you
If anyone needed a lesson in how to present complex information in a digestible form I would direct them to this channel and its siblings (including 'History Time'). Well done on another quality video.
I can't tell you how many times I'm about to go to sleep when I see a new video posted. Too many times I stay up an extra hour. Once I tried to sleep instead but ended up watching the whole video around 3am!
Hands down the greatest TH-cam channel of all time. The quality and speed of uploads is just insane. And we're getting this for free... I watch and rewatch these videos often in my spare time and before sleep. Thank you, History of the Universe, never change!!

I can’t express how much I’ve appreciated your work across this channel and others. It’s been a staple for me for at least 4 years now. Keep up the good work!
Black Holes still follow logic based on their gravitational behavior and spin, so their interior is probably describable by some kind of equation that we haven't found. At least I hope that's the case
One of the best intros I've seen in a while, you guys simply do not miss!! Much love from Colorado, keep up the stellar work. More content should be of this knowledge/quality....
I second that. Most people do not like these intense science topics. They are happy never thinking about them. Oblivious and ignorant fools if you will. I love learning about these cosmic phenomena that represent the most extreme of nature. It terrifies most people because they are indifferent to it. I no longer care. I learn and enjoy it for me. Not anyone else
I’ve tried myself either they think I’m crazy or don’t really listen or care… so I just go back watching them alone in amazement but it doesn’t seem to translate to others. 😔
1:52 If anyone else wondering why you need only 1 number to describe angular momentum of a black hole: This is because black hole is axially symmetric and the fact that we only describe black hole, not its position in space.
I am looking at mine right now…. I mean my ex-wife’s schwarzchild radius instead of a heart. Is it possible to still cohabitate with her[the ex-wife]while remaining a full time dad with my three active kids (5,6,8) and also the occasional gigolo so she’s stays tame and doesn’t throw me out on my ass…. Because I’m an asshole and I trusted her with the money because we’d been together since we were 13…. Def an asshole… don’t trust anyone. Ever. Except your kids. Your kin. That’s it. God damn shi has me deadass burnt the fuck out on all this shi fr fr

I just wanted to say thank you for putting out such well researched and thought provoking content. Now days it’s so easy to get caught up in all the day to day crap that frankly makes me sad and depressed. But when I watch videos like this it reminds me that there’s a huge fascinating universe out there and that what makes life worth living is to find knowledge and mysteries of the natural world to bask in the fact that we are all apart of this living universe. So again thank you very much and please keep up the excellent work! 😊
This channel is usually so good with accurate information, why pass on the false layman's explanation that Hawking radiation is a particle-antiparticle pair of virtual particles with one falling in and one escaping? In the same time it took to go over matter/antimatter virtual particles, they could have explained the Unruh effect's virtual particles that actually create Hawking radiation. All that did was leave me feeling for the rest of the video that I couldn't trust what they were saying. They added so much detail to an explanation that's false, it would look so believable to someone who doesn't already know...
The fact that you don't gust treat a black hole as some magic physics mystery bag is a breath of fresh air. Still to fantastical at moments. Especially at the end. Black holes are no more complex than any other stellar body in the universe, even if they are an extreme end of things.
What I like about science most is, that the formulas and math can describe something we never knew would exist, then test if it does and finally find and prove it. Amazing how old the idea of a black hole actually was. And amazing that these objects actually exist out there.
Omg guys did you imprive your musicalization or something? Like your very first video already felt "Full blown documentary quality", but this one somehow feels even better? Like the music was on point, the edition was even more perfect than it was before and so on. Your channel is truly an special one
Absolutely fantastic documentary. Thank you so much for explaining Hawking Radiation in a way I can finally understand it. Fantastic production and love the analogies throughout. Thank you so much!!!
I say this every time and I know it’s not original but thank you very much for all of this. It is fascinating delightful intimidating and awe inspiring. You do a superb job. A wonderful contribution to science.

Excellent video as always. Content like this becomes ever rarer as the internet is increasingly flooded with low effort slop and other forms of cheap entertainment. Ironically this video about black holes is a shining beacon in an otherwise empty void of ignorance. Amazing work!
Watching these makes me feel like inside a cave at pre-historical times , around a small fireplace ready tho hear a new story from the wise man of the tribe . It sure does .
Ok, we want to know what happens below the event horizon. First, we need to know what happens outside the blackhole. A blackhole has a event horizon, a accretion disk and angular momentum. The blackhole spins hot plasma matter it catches from the galaxy, in a accretion disk. As a result, that hot plasma matter gets converted into high energy particle blazers. And shot out in the form of cosmic jets at 99% of C. That is it's purpose. It's a matter energy converter. You might say why ? Because if a galaxy like our milky-way had to much matter, it would collapse and only be a giant blackhole the size of the entire milky-way. With no stars or planets and we wouldn't be here on earth right now. In other words, this (M🔼(+E) = 99% of C. The triangle is a science symbol delta, delta means to convert to change something. Now you know what happens outside the blackhole. Now what happens below the event horizon that void ? For close to 50 years, they said below the event horizon all that star matter was crushed to infinite density. And was still some form of matter(M). In other words, this (M=M=singularity). But now they say there is no singularity no M. Now what happens below the event horizon. Maybe, we can do a experimental blackhole equation. This is the equation ((event horizon = g)×(spacetime= tidal forces)> (300,000 km/s) =(+E =C)^(+E🔼(-E)= (negative repulsive energy)= (expansion rate of our round bubble or toros universe)= the Hubble Constant. Remember 🔼 means to convert to change something. In other words, +E beyond the event horizon is spaghettified( science term to stretch). By tidal forces(fabric of space) traveling faster then C below the event horizon. To a Quantum State(the smallest possible energy particle), something we've never seen before, because we can't make a blackhole in a laboratory. That particle is negative repulsive energy (-E). Not anti-gravity because gravity (g) is a gravity well, curved space-time. You might say why doesn't +E stay as +E after spaghettified. Because it would just start to clump up from a Quantum State and become plasma matter again. So as negative repulsive energy (-E). It will travel below the event horizon using tidal forces(spacetime) and help our universe to continue to expand. So its a matter energy converter above and below the event horizon. Now time dilation it affects +E above the event horizon. It slows down the amount of +E that crosses the event horizon. Perhaps 1% of (+E) crosses the event horizon. But you might say, how can the universe expand with just 1% of (-E). Because there are 2 trillion galaxies(with blackholes) in the observable universe and trillions more beyond the cosmic horizon(unseen galaxies). All those trillions of galaxies(with blackholes) are converting positive +E to negative -E. And helping our universe expand.
This video isn't about the expansion of the universe. But I'll try to answer your question. First most scientists now say , that blackholes have something to do with (repulsive energy) (dark energy). Ok, let's use a example of 4 quadrants. Quadrant 1 has 4 galaxies(4 blackholes) quadrant 2 has 3 galaxies( 3 blackholes) quadrant 3 has 2 galaxies (2 blackholes) and quadrant 4 no galaxies (no blackholes). Remember what I said in the blackhole equation (-E) is repulsive energy. Ok, simple question? which quadrant produces the most (-E). Quadrant 1, 2 ,3 or 4. Quadrant 1 has 4 galaxies( 4 blackholes). It produces the most (-E) to help our universe expand. Quadrant 2 has 3 galaxies( 3 blackholes ) producing (-E) to help our universe to continue to expand etc,etc,etc. Now Quadrant 4 has no galaxies( no blackholes), so 4 doesn't produces any (-E). As a result, some part of our universe don't expand evenly. But quadrant 4 still expands because it still receives (-E) from Quadrant 1, 2 and 3, It expands slower and uneven. @@nevill2947
The only part of this video I find perplexing is the fact anyone would think a large black hole would be cooler than a small one? That makes perfect sense. The larger the surface area the faster heat can escape.
The heat of a black hole escapes as Hawking radiation. With a larger black hole, you have more wavelengths available for that radiation to escape as, including radio waves. However, the smaller the blackhole is, the shorter the available wavelengths become, so only high energy photons can be formed, meaning it has to be hotter.
I would happily pay $10+ if you could a video of similar quality but on speculations on what's after the black hole. What's after Hawking radiation? What are Roger Penrose's thoughts? I would also like to hear what are their most outlandish theories. Episodes like that could really sparks someones idea who works in this field day in and day out.
As I was watching this I was compelled to pull out my copy of Brief History of Time and wipe a little dust of the jacket. Fantastic video series. 👍. It's the best I've seen.
Another fascinating video on an extremely complex and beautiful subject made so easy to digest! Such a wonderful quest for knowledge! Thank you History of the universe for a wonderful video on black hole connecting topics, helping those of us that love this subject and lack the mathematical language to describe it ❤
The most relaxing, anxiety-soothing voice talking about what I personally consider to be the second most mind-bending, existential-crisis-inducing subject in space. This is gonna be FUN.
The fact that Black Hole’s entropy grows with its area reminds me of the Fuzzball theory, which states that there is nothing inside a black hole, as in there is no space there, it’s like a large bubble of no-space (think Swiss cheese holes), and all information/strings are stored on the surface. That also resolves the singularity paradox, as there isn’t one.
We are in a transformation from infinity density and zero space time to zero density and infinite space time. For this to happen all energy needs to be broken down into its smallest component (photons) before passing through a singularity where this information is transported into the past which is all we can observe. As more information passes through black holes it increases the amount of information in the past which expands into us into the future.
WTF as you actually on about? Just because you dreamed something and decided to write it down, that DOESN’T mean it true. 🤥And wtf is zero spacetime and infinite spacetime supposed to mean?🧐 What you wrote is absolute and complete bullshit. It has ZERO basis in reality or ANYTHING to do with logic and actual physical phenomenon. You obviously haven’t realised but this video is NON-FICTION. It’s talking about our reality, not some sci-fi make believe garbage… Like yours, for example. 😂🤪🤪
My first "encounter" with a black hole was in a mid-1970's sci-fi T.V. show called, "Space: 1999". There was one episode called "Black Sun", which turned out to be my favorite episode, because of the philosophical tone, and the psychedelic, "cosmic" scenes near the end. After that episode, I became convinced that a "Black Hole" was ALWAYS the result of a dead star. My next encounter was a few years later was a few years later with the Disney movie, "The Black Hole" with Maximillian Schell as the baddie.
I'll let you in on a secret, that's the entire channel. On the earth without photosynthesis episode, it just keeps going into different tangents and only answers the question of the last five or 10 minutes of the video. I personally think it's part of the charm, all the tangents are usually useful context or the history of the context and is quite interesting.

It produces the most (-E) to help our universe expand. Quadrant 2 has 3 galaxies( 3 blackholes ) producing (-E) to help our universe to continue to expand etc,etc,etc. Now Quadrant 4 has no galaxies( no blackholes), so 4 doesn't produces any (-E). As a result, some part of our universe don't expand evenly. But quadrant 4 still expands because it still receives (-E) from Quadrant 1, 2 and 3, It expands slower and uneven.

Thanks. I needed this today.
Great stuff. I love these every time they come out,
My favorite science channel.
Covering my favorite subject.
*I'm in Heaven*
*Absolute, Pure Joy!*
Three cheers for HotU and the legendary David Kelly.
Great, man. This will definitely boost up my energy as I am on my way of understanding black hole ( beginner )!
1:13 your ma
Ha! Gottem!
😮
Noooo you beat me to it 😂😂
"Think of a supermassive ballerina."
Me: "no thank you."
The only thing in the universe that don’t lose numbers when she enters a black hole is….😂
Imagine how prestigeous a channel you would have to be to get Prof. Joseph Conlon to write for you?
Let's goo another sleeping video to add to the playlist
I like the bigger focus on history stories. Really give a food feeling for how things where found out
Fake news @19.00th minute: 'Black holes have no hair'.
I know for sure that my black hole has hair.
Absolutely love this channel. My favorite on YT.
The only part of this video I find perplexing is the fact anyone would think a large black hole would be cooler than a small one? That makes perfect sense. The larger the surface area the faster heat can escape.
Sure, but since there is no surface and not even light escapes it - it's understandable why people would make that assumption
The heat of a black hole escapes as Hawking radiation.
With a larger black hole, you have more wavelengths available for that radiation to escape as, including radio waves.
However, the smaller the blackhole is, the shorter the available wavelengths become, so only high energy photons can be formed, meaning it has to be hotter.
What’s inside a black hole 🕳️??
A man with a flash light searching for the circuit breakers 😂
Literally the first channel to show a black hole from underneath. Please show me another. Fckn love this channel
Good night everyone
Today is going to be a good day, HOTU video drop, what could be better than 56 minutes of black hole stuff from the best astrophysics channel ever 😎
I would happily pay $10+ if you could a video of similar quality but on speculations on what's after the black hole. What's after Hawking radiation? What are Roger Penrose's thoughts? I would also like to hear what are their most outlandish theories. Episodes like that could really sparks someones idea who works in this field day in and day out.
Whaaaaaatttt????!!! HOTU posts and I have to go to work!!!! Noooooooo!!!!!!!!
I‘m SO excited every time you post!
yes, keep making me wonder
As I was watching this I was compelled to pull out my copy of Brief History of Time and wipe a little dust of the jacket. Fantastic video series. 👍. It's the best I've seen.
Black hole sun, won’t you come?
🙃
Another fascinating video on an extremely complex and beautiful subject made so easy to digest! Such a wonderful quest for knowledge! Thank you History of the universe for a wonderful video on black hole connecting topics, helping those of us that love this subject and lack the mathematical language to describe it ❤
“Thanks to my heritage for supporting educational content on youtube” lmao
A truly astounding channel! Always impressed!
The most relaxing, anxiety-soothing voice talking about what I personally consider to be the second most mind-bending, existential-crisis-inducing subject in space.
This is gonna be FUN.
Honestly when I'm feeling anxious I find his narration, with the pregnant dramatic pauses, kind of the opposite of relaxing.
I'll be heartbroken, shocked, and disgusted if this video doesn't mention OEM 2011 Land Rover SE head gasket replacements being in black holes.
A hole is a hole. - Vanilla Ice
The fact that Black Hole’s entropy grows with its area reminds me of the Fuzzball theory, which states that there is nothing inside a black hole, as in there is no space there, it’s like a large bubble of no-space (think Swiss cheese holes), and all information/strings are stored on the surface. That also resolves the singularity paradox, as there isn’t one.
We are so back
Lol, what?
@@Deletirium When HotU does't upload, we are in fact not back
Im not just saying this.. every time you say "fartshield" I pause the video and drink a beer.
Imagine not being hyped when one of these videos drops...
What's inside a black hole? A lot of stuff knocked in there by an extremely large, black cat.
We are in a transformation from infinity density and zero space time to zero density and infinite space time. For this to happen all energy needs to be broken down into its smallest component (photons) before passing through a singularity where this information is transported into the past which is all we can observe. As more information passes through black holes it increases the amount of information in the past which expands into us into the future.
Psuedobabble disrespects what this channel stands for.
@@Jeewanu216agreed, but we’ll look pretty funny if this guy turns out to be right
@@jacksonhawkins9176 Saying photons are the smallest component of energy is more than enough for me to be sure as hell that won't happen.
All energy ❌
All matter✅
Hopefully that fixes it 😂
WTF as you actually on about? Just because you dreamed something and decided to write it down, that DOESN’T mean it true. 🤥And wtf is zero spacetime and infinite spacetime supposed to mean?🧐
What you wrote is absolute and complete bullshit. It has ZERO basis in reality or ANYTHING to do with logic and actual physical phenomenon. You obviously haven’t realised but this video is NON-FICTION. It’s talking about our reality, not some sci-fi make believe garbage… Like yours, for example. 😂🤪🤪
My first "encounter" with a black hole was in a mid-1970's sci-fi T.V. show called, "Space: 1999". There was one episode called "Black Sun", which turned out to be my favorite episode, because of the philosophical tone, and the psychedelic, "cosmic" scenes near the end. After that episode, I became convinced that a "Black Hole" was ALWAYS the result of a dead star.
My next encounter was a few years later was a few years later with the Disney movie, "The Black Hole" with Maximillian Schell as the baddie.
At the singularity you will find socks that went missing from the dryer
Legit one of the best channels on the platform, hands down. It's sooo well done, it's crazy.
Last time I was this early, my GF was disappointed

My God. I think he's right!
Thank you so much for posting these. They’re simply amazing. I just love watching them to wind down at night.
I probably shouldn't watch this while I'm high.
While high on what ?
Cocaine or Weed
Just the 2 drugs you know 😮
Wym this is peak stoner material
You misspelled “should”

Severely underrated channel. I really love you guys and gals.
NEW HISTORY OF THE UNIVERSE VID JUST DROPPED
LETS GOOOOOO
loved this video just like all of your videos its awesome!!!
One Punch Man ended up inside a black hole. He was fine.
Bro was bench pressing them
I like how some German guy was depressed and figured out some hectic astronomical phenomena to try and get over it.
Depression is one hell of a drug.
Good vid but the title is a bit misleading. Only at 43:03 do you begin to discuss what is INSIDE a black hole…
I'll let you in on a secret, that's the entire channel. On the earth without photosynthesis episode, it just keeps going into different tangents and only answers the question of the last five or 10 minutes of the video.
I personally think it's part of the charm, all the tangents are usually useful context or the history of the context and is quite interesting.
Shhhh don't ruin the quality longform content 😊
That's because channels like this are most probably AI generated content
"Great course but the name is a bit misleading. Only halfway through the calculus course did we begin to discuss derivatives and integrals."
Sometimes you need to understand what limits are before learning how differentiation works

All I’m saying is the vast majority of vid should be directly related to the title. If I click on a 50 min. vid about Seawolf class subs I’m not signing up for a 40 min. primer on the history of submarine warfare. If that’s not directly analogous you at least get my point.
Edit: Some might say it’s a minor thing, chill. I’d say there’s WAY too much said tactic or whatever you want to call it. It’s a cheap way to quickly post another vid. Moneyshot title with B-roll filler and nearly no original content. To those who say “chill! You’re getting quality content for free!” I’d reply: “ they’re doing it to make money and even if I didn’t pay out of pocket I’d be paying with my time and eyeballs on the ads.” No?? Am I way off base??
HOTU and HOTE uploading the same week noiiiiiiiicee
