that single sentence put the singularity into perspective for me. absolutely rocked me and gave me a dissociative episode, but blew my mind at the same time
what more interesting is that spaghettification only happens in eternal black holes, or schwarzschild black holes. those are black holes that dont have a charge or angular momentum (spin), and always existed at the beginning of the universe. black holes that more accurately reflect ones we see in nature, which are rotating and have charge, are known as kerr black holes. in a kerr black hole, you actually get flattened at the event horizon! so, pancakeified!
Such a brilliant creator who creates videos that are amazing in so many ways. I am always taken aback by the level of research done into these. Not only do you collate an incredible amount of information about these topics, but you extensively understand them to the point that you can calmly explain them to the layman. Couple this with the pacing of your diction, the fantastically edited graphics and the intrigue of the source material; here is of the most underrated channels on RUclips, and certainly one of the most deserving subs that I've made.
@@sea_space so if a neutron star is about 20 km around, so the singularity at the center of the black has no volume but a mass of up to billions of times sun? That's pretty cool
“Black holes ain’t as black as they are painted. They are not the eternal prisons they were once thought. Things can get out of a black hole both on the outside and possibly to another universe. So if you feel you are in a black hole, don’t give up-there’s a way out.” -- *Stephen Hawking*
What if blackhole is actually , a kind of star inside its Event horizon. it's possible . May be it's real Quark star made of dense quarks but due to its fast escape velocity faster then C it's black . It's my theory but no one can test it 🤔. If this is true , i Will Be Disappointed most. Because i want blackhole as scientist thinks made of pure dense spacetime.
@@omsingharjit thats possible i believe there are spacial dimensions close or surrounding the anomaly. An expanse of white with a puddled black pool that threads into the higs field
I think they are eternal but Jesus Christ destroyed the power of the abyss so when you feel like you're in an abyss come to Jesus John 3:16 For God so loved the world that He gave his only Begotten Son that whosoever shall Believe in Him shall not perish but have eternal life and this includes the power of those damn black holes.
"What a privilege it is to be alive at such a time when we know so much..Something that has been said many times before and will be said again, and again...forever."
I’m very impressed by how much you studied on this subject and how accurate this video is. I have a degree in physics (though I haven’t used it in years) and everything, from the smallest details like the differences in tidal forces based on the size of the black hole, or even comparing the earths orbit if a black hole replaced our sun are so spot on. You’ve gained a loyal subscriber. Thank you for this great content.
Im so glad I found this channel. Space is and will always be my biggest curiosity. The loop of time, multi universe theory, time travel and ETs really make you feel like nothing. Makes you value life a little more too.
In learning about black holes, I’ve heard the phrase “time and space switch roles” so many times, but it was always so hard for me to visualize and comprehend the true meaning of that statement. You described it in such an elegant and simple manner, giving me such an awesome *I get it!!* moment. Thanks for that!
I’ve not before now ever heard about the fact that a singularity is an event. Having heard it as you described it has brought a much greater understanding of black holes than I previously had. The term event horizon also now makes much more sense, as it is a perfectly chosen term. Edit: thank you, kind Sir.
I've watched dozens of your videos now and I can honestly say you have an incredible gift for explaining this subject matter, I hope you are proud of these videos, they are a great gift to people around the world,
Dude I can't get enough of your videos. Been watching for about 2 years and glad I can finally give you some $$ directly for all your incredible work! Easily my favorite channel on RUclips and I recommend it to my friends all the time. Please don't stop!
There are quite a few science channels on youtube who puts out content faster but none of them put up the high quality vids that SEA does. You really raise the bar.
Major respect to SEA. He was able to go outside of the Milky Way to get some footage of black holes! That shows his amazing dedication to this space content
Black holes are insanely beautiful! Fiery colors outlining an invisible sphere. Absolutely stunning! How amazing it would be to see one in real life 🔥👀😍
What if, in the Big Crunch scenario, once the “Extremely Ultra-Massive Blackhole” has consumed the entire universe, gravity no longer exists and thus serves as the beginning of a new Big Bang?
I've thought the same too. What if at some time some hypermassive black hole has such unforeseen effects that the universe starts to shrink. Leading to a stop in expansion and acceleration towards shrinking. With such an insanely powerful collapse at the end that there would be a new big bang. The universe would just pulsate forever.
I mean, if you fall into a blackhole - who says there isn't a universe in there? The singularity doesn't just "delete" matter right? It has to go somewhere and there's probably stars, galaxies and planets in there. We might be just inside a blackhole yet to fall into the singularity which is the "big crunch".
What a magnificent breakdown and explanation of Black Hole physics - so well communicated and beautifully illustrated... bravo...!!! I love your presentation!!!
With all the astronomy channels, SEA is probable the one who best explains things, and without the need of inventing creazy theorys. Man you are legend

I think this just might be the best video I've ever seen on the subject of black holes. And I have seen a lot of them. I learned so much not only about black hole collisions but also about the nature of black holes themselves. Truly amazing content! Well worth the wait.
Many people are terrified by the prospect or being consumed by a black hole, and I used to share that sentiment. After this video, I'm actually fascinated by the prospect.

I watched your Gas Giants video almost 10 times and I'm not done yet. I think I'll watch this one more like 20+ times. The content you create is just simply amazing, thank you for this Sir.
I really love this channel, and it seems to be getting even better with time. Another favorite of mine was the one on neutron stars. I'd never considered neutron stars to be a kind of massive catastrophe before, and it revealed their power quite effectively. This is now another favorite. Black holes seem to be a source of continual fascination.
I feel like the mystery behind The Great Attractor would be a good subject to touch on if it hasn't been already. This black hole video made me ponder over it.
Man I remember watching Interstellar and seeing Gargantua for the first time and knowing that was what they looked liked, except closer they would be a little blue more than black, because my grandfather used to draw black holes in what they would really looked like. It was a match and it blew my mind. My grandfather was an AeroSpace Engineer who worked on Hubble (I have his award that has a piece of bubbles insulation), Skylab ect. Man I wish he was still alive for the pictures of the black holes. He would have been so cocky for months.
Wow, black-holes are pretty insane, especially when it comes to bending space itself... *Reminds me of something I've heard of called an axion-boson star, which were a very interesting type of “invisible” star that could’ve existed during the early universe.*
I love it when you said “if you think about it”… as if we were all completely following the physics and were basically all ready to provide the ultimate explanation of what happens in a black hole😅
I love this channel. When I have children this is the type of content I would love to show them. RUclips is amazing- independent documentarians are amazing. Thanks!
yes ! yes ! yes! finally some relativistic explanations for the event horizon and not just "speed of light" ! The problem i have with mainstream simplistic explanations is that light speed is not the factor of why nothing can escape. Escape velocity means only something if there is no acceleration. For exemple, with the mainstream explanation, everything could escape the black hole as long as it as an constant acceleration a tiny bit superior to the acceleration caused by the black hole gravity pool. With that explanation, even at 1m/s (far from the speed of light) a body could escape the inside of the event horizon. With a more relativistic approach, with a space-time wareped so much that space and time are inverted (there is only one way to travel through space -> to the singularity), there is the real explanation of the event-horizon. No event can influence the outside world because the only way the information produced by this event can spread in space time is towards the singularity. And that why the event-horizon is called like that. Thank you for doing more than the mainstream simplistic explanation.
@@thebeast6494 I hope you'll read that thing I just wrote. As I'm not a native english speaker it took me nearly 2 hours i think to write. xD I'd rather say that causality is a frontier in the flow of time (the speed of light is not about light, it is the speed of causality first, the light being able to travel at that speed only because it is massless). It is a fundamental property of space-time as we know it. (I'm not saying you're wrong here, I'm only putting here my casual person understanding AAAAAAND i'm very very very far from being even a 1rst year student in physics xD) No matter can go faster than the speed of causality and that's why light can't go faster than the speed of causality (or the max speed an event can influence space-time with the principle "causes before the consequences"). From the massless photon's point of view, travelling at that speed makes its travel instantaneous (yes it's time dilatation, the faster you go the slower your time flows foreward). It's like it is frozen in time. It can't go faster, no matter what, because a photon is a matter particule and matter particules are bound to the forward direction in time. But Mathematics predict that time can go forward or backward ! There are things who are able to go backward in time and they are bound to the backward direction in time. They can't go forward no matter what. For them consequences comes before causes. If we apply the same principles, there is also point where for them consequences happens at the same time as the causes. So there is a also a speed limit for those things travelling in the backward direction of time. The faster they go, the slower their time flows backward and the slower they go, the faster their time flows backward (same time dilatation principle). This is also shown with Feynman diagrams where matter goes foreward and anti-matter goes backward. So, you can't go faster than light because if you cross the causality speed limit you are not accelerating. You are only traveling at the same speed but backwards in time. And to travel backward in time, you'd need to become made entirely of anti-matter. That in itself is a big problem to solve : how matter can become anti-matter ? The second problem is what happens when your present self made of anti-matter goes back in time and meets your "past" self made of matter (because both will share the same place in space time, the only difference is the time direction) ? Instant world ending kaboom ? That being said it is only for our space-time arragement in our universe (aka outside the black hole) but black holes have an intersting property. When we follow the wold lines in space time (to show all the possible futures you could go to and the possible pasts you could come from in space-time) with the Kruskal-Szekeres coordinates system we can see that space and time are inverted (sort of) inside the event-horizon. We as matter beings could travel through time (like here outside the event-horizon we can travel through space) and space becomes an unidirectionnal flow pointing towards the singularity. The problem is how could we travel through time since we were made in and for a space-time arrangement where time flows in only one direction for matter ? How could we create something to travel through time in our universe not made to allow that at all ? So, if our matter not made for this kind of space-time arrangement manage to "survive" and if we manage to travel in time at the maximum time-speed we could be frozen in space and not fall into the singularity. And so depending when we decide to time-go we could cross again the event horizon. It could be an other place in our "normal space time" (but we would still have to convert speed again and again and again to stay on the limit because we would refall beyond it) or in an other space-time arrangement (aka not our universe) where we could go anywhere in space (like our arrangement of space-time) but where the time flows backwards for matter (the event horizon acting like a time-inverted white hole horizon limit because it would expluse matter in that universe). Then we could go to an inverted black-hole and with the same principle of space-time inversion we could reemerge in our universe through a normal white hole. And that without exploding due to antimatter ! AAARRRG complicated ..... headache xD That's my understanding of the thing (and i'm pretty sure I made plenty of mistakes). And that's why i find the "light speed escape velocity" explanation meh. There is something way more fundamental to that. I'm not saying it is wrong, only it is unsatisfying. The "light speed escape velocity" is not the cause of the event-horizon, it is the consequence of a fundamental change in the space-time structure to the point where causality breaks and becomes something else. The points in our space-time where causality as we know it is twisted ... where events as we know them can only be directed towards the singularity ... where no inside events as we know them can reach the ouside for us to observe due to space-time properties ... the points where we can't obesrve inside events anymore from the outside ... the points where our horizon of obseravtion stops ... the event-horizon of a black hole. I hope it was readable xD
Mate as soon as my phone dings with a notification that SEA have uploaded a new video... instantly click and not once have I ever been disappointed, I think 90% of us space nerds can a agree a collision between two black holes is among the most prized of all space content and context, .. and you sir deliver us this much anticipated content consistently covering all corners and execute it like a boss!
I was always fairly puzzled by people being confused about black holes in the Pair Instability Gap existing. Since Black Holes can gain mass by consuming material, a large stellar black hole could just merge with another black hole, some stars, or maybe even nebula gasses in sufficient quantity.
How do space and time switch posions? How does it actually happen? If a black hole has a theoretical infinite point, why won't it be ever expanding or what will two singularities actually do to eachother when two black holes collide? How can something infinite become...more infinite?
BUDDY keep making videos you are so awesome! you dont make em enough! ive watched literally every single one multiple times. much love brother keep it up you rule!
Thank you Sam Anderson for such excellent videos, so objectively and integrally speaking truthful science, without any hype or sensation, without insulting our intelligence, without any over-production or heavy-laden soundtrack. May you keep SEA going strong, god bless these stellar productions! I would like to own DVD's of this content so that the algorithm can't gobble it up like a black hole! I hope you never get sucked into any shite organization...
Quick! SEA has uploaded! Seriously though, love your videos, keep going please, it's rare for me these days to actually watch a video instead of just listening to it in the background, your videos are the exception to the rule.
Strange thing is, we actually know very little about black holes ! More questions than answers. Probably the reason science is still so fascinated by black holes.
SEA has always such incredible videos about such amazing topics. This channel has made me so much more interested in outerspace and im really great full for all the great content he is providing. Thank you!
@@BulletFever1 : Intense gravity compresses space; the distance between molecules would also squish together... meaning we could fall into a black hole and probable not notice anything. Emailed Professor Massey at IC London, and he wasn’t comfortable acknowledging quantum gravity effects, but to me, the idea of spaghettification just doesn’t sound even possible, if we apply the full definitions as given. Maybe I’m wrong, of course. Just would like to explore the concept before overlooking what seems a contradiction.
The effect is caused by a gravitational differential, when the infalling matter is close to the point at which gravitational forces increase exponentially so that the matter closer to the event horizon is being pulled on at an exponentially faster rate than the matter behind it, resulting in the matter being "stretched".
Everytime I watch a video like this I always try to picture everything exactly how it was explained. I also always think what if we get to point where we can travel around in out of space and imagining the space craft picking up a reading of a black hole with no accretion disk. How crazy it would be to look out a window and see nothing but the radar show that its there. Also seeing an active one with an accretion disk would be amazing to see as well.
“Just like you can’t escape that early start tomorrow morning”
That hurt
that single sentence put the singularity into perspective for me. absolutely rocked me and gave me a dissociative episode, but blew my mind at the same time
When you get spaghettified, you are on your way pasta event horizon.
How did this not get a million likes lol
what more interesting is that spaghettification only happens in eternal black holes, or schwarzschild black holes. those are black holes that dont have a charge or angular momentum (spin), and always existed at the beginning of the universe. black holes that more accurately reflect ones we see in nature, which are rotating and have charge, are known as kerr black holes. in a kerr black hole, you actually get flattened at the event horizon! so, pancakeified!

Nostalgia intensifies
Amazing content as usual, Thanks for the videos SEA
I feel like the mystery behind The Great Attractor would be a good subject to touch on if it hasn't been already. This black hole video made me ponder over it.
Well done! This is a fantastic channel
Favorite space channel talking once again about my favorite celestial body
I love that sea was able to move to other content and is still wildly successful, also, space is awesome!
Read the title and now I’ve got when worlds collide by powerman 5000 stuck in my head lol
Man I remember watching Interstellar and seeing Gargantua for the first time and knowing that was what they looked liked, except closer they would be a little blue more than black, because my grandfather used to draw black holes in what they would really looked like. It was a match and it blew my mind. My grandfather was an AeroSpace Engineer who worked on Hubble (I have his award that has a piece of bubbles insulation), Skylab ect.
Man I wish he was still alive for the pictures of the black holes. He would have been so cocky for months.
Wow, black-holes are pretty insane, especially when it comes to bending space itself...
*Reminds me of something I've heard of called an axion-boson star, which were a very interesting type of “invisible” star that could’ve existed during the early universe.*
MattSnows bending space ain’t even the most impressive lol. Black holes literally bends and stop time
@@Phantom-bh5ru Lol I agree but I have to tie it into Axion-Boson stars somehow
I love it when you said “if you think about it”… as if we were all completely following the physics and were basically all ready to provide the ultimate explanation of what happens in a black hole😅
I love the videos sea, mad respect goes out to you for putting together such fascinating and fun vids to watch. Keep it up ❤️
Truly one of the best and most interesting videos on black holes on RUclips, fantastic work!
An absolutely fantastic video. So well explained and produced. Bravo!
The level of the content this channel creates is truly amazing.
Wonderfully informative and awe inspiring. Thank you for your work, thank you.
I love this channel. When I have children this is the type of content I would love to show them. RUclips is amazing- independent documentarians are amazing.
Thanks!
yes ! yes ! yes! finally some relativistic explanations for the event horizon and not just "speed of light" !
The problem i have with mainstream simplistic explanations is that light speed is not the factor of why nothing can escape. Escape velocity means only something if there is no acceleration. For exemple, with the mainstream explanation, everything could escape the black hole as long as it as an constant acceleration a tiny bit superior to the acceleration caused by the black hole gravity pool. With that explanation, even at 1m/s (far from the speed of light) a body could escape the inside of the event horizon.
With a more relativistic approach, with a space-time wareped so much that space and time are inverted (there is only one way to travel through space -> to the singularity), there is the real explanation of the event-horizon. No event can influence the outside world because the only way the information produced by this event can spread in space time is towards the singularity. And that why the event-horizon is called like that.
Thank you for doing more than the mainstream simplistic explanation.

I hope you'll read that thing I just wrote. As I'm not a native english speaker it took me nearly 2 hours i think to write. xD
I'd rather say that causality is a frontier in the flow of time (the speed of light is not about light, it is the speed of causality first, the light being able to travel at that speed only because it is massless). It is a fundamental property of space-time as we know it. (I'm not saying you're wrong here, I'm only putting here my casual person understanding AAAAAAND i'm very very very far from being even a 1rst year student in physics xD)
No matter can go faster than the speed of causality and that's why light can't go faster than the speed of causality (or the max speed an event can influence space-time with the principle "causes before the consequences"). From the massless photon's point of view, travelling at that speed makes its travel instantaneous (yes it's time dilatation, the faster you go the slower your time flows foreward). It's like it is frozen in time. It can't go faster, no matter what, because a photon is a matter particule and matter particules are bound to the forward direction in time.
But Mathematics predict that time can go forward or backward ! There are things who are able to go backward in time and they are bound to the backward direction in time. They can't go forward no matter what. For them consequences comes before causes. If we apply the same principles, there is also point where for them consequences happens at the same time as the causes. So there is a also a speed limit for those things travelling in the backward direction of time. The faster they go, the slower their time flows backward and the slower they go, the faster their time flows backward (same time dilatation principle). This is also shown with Feynman diagrams where matter goes foreward and anti-matter goes backward.
So, you can't go faster than light because if you cross the causality speed limit you are not accelerating. You are only traveling at the same speed but backwards in time. And to travel backward in time, you'd need to become made entirely of anti-matter.
That in itself is a big problem to solve : how matter can become anti-matter ? The second problem is what happens when your present self made of anti-matter goes back in time and meets your "past" self made of matter (because both will share the same place in space time, the only difference is the time direction) ? Instant world ending kaboom ?
That being said it is only for our space-time arragement in our universe (aka outside the black hole) but black holes have an intersting property. When we follow the wold lines in space time (to show all the possible futures you could go to and the possible pasts you could come from in space-time) with the Kruskal-Szekeres coordinates system we can see that space and time are inverted (sort of) inside the event-horizon. We as matter beings could travel through time (like here outside the event-horizon we can travel through space) and space becomes an unidirectionnal flow pointing towards the singularity. The problem is how could we travel through time since we were made in and for a space-time arrangement where time flows in only one direction for matter ? How could we create something to travel through time in our universe not made to allow that at all ?
So, if our matter not made for this kind of space-time arrangement manage to "survive" and if we manage to travel in time at the maximum time-speed we could be frozen in space and not fall into the singularity. And so depending when we decide to time-go we could cross again the event horizon. It could be an other place in our "normal space time" (but we would still have to convert speed again and again and again to stay on the limit because we would refall beyond it) or in an other space-time arrangement (aka not our universe) where we could go anywhere in space (like our arrangement of space-time) but where the time flows backwards for matter (the event horizon acting like a time-inverted white hole horizon limit because it would expluse matter in that universe). Then we could go to an inverted black-hole and with the same principle of space-time inversion we could reemerge in our universe through a normal white hole. And that without exploding due to antimatter !
AAARRRG complicated ..... headache xD
That's my understanding of the thing (and i'm pretty sure I made plenty of mistakes). And that's why i find the "light speed escape velocity" explanation meh. There is something way more fundamental to that. I'm not saying it is wrong, only it is unsatisfying. The "light speed escape velocity" is not the cause of the event-horizon, it is the consequence of a fundamental change in the space-time structure to the point where causality breaks and becomes something else.
The points in our space-time where causality as we know it is twisted ... where events as we know them can only be directed towards the singularity ... where no inside events as we know them can reach the ouside for us to observe due to space-time properties ... the points where we can't obesrve inside events anymore from the outside ... the points where our horizon of obseravtion stops ... the event-horizon of a black hole.
I hope it was readable xD

I'll check it, thank you ! ^^
Mate as soon as my phone dings with a notification that SEA have uploaded a new video... instantly click and not once have I ever been disappointed, I think 90% of us space nerds can a agree a collision between two black holes is among the most prized of all space content and context, .. and you sir deliver us this much anticipated content consistently covering all corners and execute it like a boss!
This is so good, really nice job
Perplexing as always SEA. Fantastic knowledge gained from this segment, hope you are doing well mate.
I'am a simple man. I see a SEA video, I press like!
I watch SEA videos when I’m high or trying to get to sleep, and that is absolutely a compliment to him
I was always fairly puzzled by people being confused about black holes in the Pair Instability Gap existing. Since Black Holes can gain mass by consuming material, a large stellar black hole could just merge with another black hole, some stars, or maybe even nebula gasses in sufficient quantity.
How do space and time switch posions? How does it actually happen? If a black hole has a theoretical infinite point, why won't it be ever expanding or what will two singularities actually do to eachother when two black holes collide? How can something infinite become...more infinite?
This is so satisfying to watch
BUDDY keep making videos you are so awesome! you dont make em enough! ive watched literally every single one multiple times. much love brother keep it up you rule!
Sea of your reading this I love your vids keep it up
Simply the best explanation of an extremely complex matter.
Thank you Sam Anderson for such excellent videos, so objectively and integrally speaking truthful science, without any hype or sensation, without insulting our intelligence, without any over-production or heavy-laden soundtrack. May you keep SEA going strong, god bless these stellar productions! I would like to own DVD's of this content so that the algorithm can't gobble it up like a black hole! I hope you never get sucked into any shite organization...
Quick! SEA has uploaded! Seriously though, love your videos, keep going please, it's rare for me these days to actually watch a video instead of just listening to it in the background, your videos are the exception to the rule.
Strange thing is, we actually know very little about black holes ! More questions than answers. Probably the reason science is still so fascinated by black holes.
SEA has always such incredible videos about such amazing topics. This channel has made me so much more interested in outerspace and im really great full for all the great content he is providing. Thank you!
I WAS LEGIT JUST THINKING ABOUT THIS WHAT
best space channel on youtube because you can't skip 2 seconds because you can miss really cool and fascinating information.
The entire concept of “spaghettification” seems to overlook an obvious principal of intense gravitic effect.
Anyone else see the flaw in the premise?
You have my interest, but I don't see it
@@BulletFever1 : Intense gravity compresses space; the distance between molecules would also squish together... meaning we could fall into a black hole and probable not notice anything.
Emailed Professor Massey at IC London, and he wasn’t comfortable acknowledging quantum gravity effects, but to me, the idea of spaghettification just doesn’t sound even possible, if we apply the full definitions as given.
Maybe I’m wrong, of course. Just would like to explore the concept before overlooking what seems a contradiction.
The effect is caused by a gravitational differential, when the infalling matter is close to the point at which gravitational forces increase exponentially so that the matter closer to the event horizon is being pulled on at an exponentially faster rate than the matter behind it, resulting in the matter being "stretched".
the way i watch your videos to fall asleep and get knocked out within 2 minutes 🤣
black holes: exist
logic: am i a joke to you?
And what about QM 🤔😂
@@omsingharjit wdym by QM?
Bet it took a strenuous amount of thinking to come up with that original comment right pal?
Black holes : my existence is beyond your understanding
@@yesandyes9168 Yeah man my brain feels like it's gonna burst.
Everytime I watch a video like this I always try to picture everything exactly how it was explained. I also always think what if we get to point where we can travel around in out of space and imagining the space craft picking up a reading of a black hole with no accretion disk. How crazy it would be to look out a window and see nothing but the radar show that its there. Also seeing an active one with an accretion disk would be amazing to see as well.
guys he said cataclysm looool funy loooooool
Another great video! Awesome work!
