A black hole is captured time. Matter that goes in loses it's time adds to the weight and mass of the black matter spaghetti"ing is what it looks like from our point of view. Speedup 3 dimensions looks like long 2 dimensions. Gravity is how fast terminal velocity is. The stronger the gravity the greater the speed. But speed is distance over time. The less time same distance the greater the speed. What we think going into a black is being stretched going insane speed and massive impact is in fact just normal falling and dieing form fall damage that is infact slowed down time it is much slower then we think we are trapped not in space but time the outside is what is faster. It trapped everything it ever ate every thing is still falling.

Nuclear reactors make energy with fission, the sun with fusion, the latter we are trying to replicate on earth, for unlimited energy, and fusion creates 4 times more energy than fission, which doesn’t sound like much, but on scale it’s day and night difference.
Basically, our universe works around the fabric created from space and time. Gravity bends this fabric. But if something has infinite gravity, it infinitely bends the fabric, or in other words, it breaks it. This means there is no meaning to space or time, and the idea that the singularity is in a place is the same as the idea that it is in a time- it just doesn't make sense! Fortunately, black holes allow us the jomo (joy of missing out) effect of not knowing how this works. But here comes the point of experiment 5- if you are able to make a singularity push things away on the same level as it pulls them in, there is no event horizon, because light can escape at any point. But this mean the broken fabric is shown for all to see. The point Kurzgesagt made, is that we don't know what we'll see, since it goes against everything in physics, and yet it is physically able to exist. It is like how imaginary numbers work. We know there is no square root of a negative number, and yet we know it can exist because we can make predictions where the square root of -1 actually functions in mathematical equasions.
The only thing that sucks about Kurzgesagt is how they try to make things simplistic and it can be misunderstood because of that. But it's a good jumping off point to understand which is why I like watching them. A lot of these things require some backstory information to set it up and without making a freaking docu-series, we get this. Going into it with a frame of reference makes it a lot easier to get. PBS Space Time is a channel I go to for a deeper dive into these things.
@@Timmycooit’s a double edge sword,make it too complex and no one understands sh-t,make it too simple and you lose the grasp of the details on what something actually is. Just them being able to bring the thought of these concepts for more people is enough for me.
@@TimmycooWell people shouldnt use this channel as their only source of information. These simplified channels exist to boost your curiosity and the interested people would look up more into it online or ask their teachers some questions and so on.
Spacetime is considered to be a "fabric". It isn't created from space and time. It is "spacetime". Gravity doesn't bend spacetime. Gravity IS the curvature of spacetime. There is no force of gravity in this model. Black holes don't have infinite gravity, nor infinite mass. They are as massive as the matter that "fell in" minus whatever they may have radiated away (I don't know if that's been observed yet or not, above my pay grade of 0 lol). Astrophysicists can tell you the mass of a given black hole. Singularities do not exist as physical objects. There is not reason to believe they do exist. The math describes the black hole. It isn't the black hole itself. The problem is quantum mechanics and general relativity don't play nice.
I would love to see more reactions to Kurzgesagt! There is so much cool, fun, and headache-inducing content worthy of being reacted to! One of my personal favorites is "The Egg," which is their narration (and visualization) of a short story by the same name.
7:19 you can image this one as looking a glass full of water from its side and strring the water with a spoon faster and faster. The faster the spin gets, the smaller the tube of distortion gets. Same applies to the black holes. The faster its spin gets, the smaller the even horizon gets. And in this video, he refers to a point that the spin is so extreme that the tube of distortion becomes just a line (so the event horizon completely dissolves because the warping of spacetime one dimensional (a line) that goes towards to dimensionless singularity (a point). Also you can visualize the time and space gets reversed by thinking a sheet of elastic plane, one side red other side blue, which starts to warp by a singularity that causes the image we all have seen online as the one dimension reduced version of the geometry of a blackhole. Then, you try to imagine the region of spacetime warping inside the event horizon becomes so drastic, it turns the spacetime (elastic sheet, one side red and the other side blue) inside out, which is represented by the red side becomes blue and the blue side becomes red when past the event horizon so that an object falling into a blackhole travels though space and time but much more through than time as it gets closer and when it hits the event horizon, it becomes kinda stationary in space and now it travels much more through time rather than space. So it doesn't fall through space per se, it falls through time that point on. It falls to future.
Since space and time switch roles, you would be able to move throughout time (inside the event horizon) whilst you could only partially move in only one direction (towards the singularity).
4:20 Actually yes. It's call Black Hole Bomb and can release more energy than all the stars of a galaxy combined in several million years. Kurzsegart did a video about that, you should see that, it's very interesting
@@johnniequinn3215 Actually no, it doesn't destroy the black hole, it just release an enormous amount of energy. The black hole is completely uneffected
@@fabriziobiancucci7702 Where does the enormous release of energy come from? If it feeds off of the black hole to generate the explosion, then that extra energy is the bleed off of mass from the black hole itself
@@johnniequinn3215 It doesn't work like that. The energy comes from electromagnetic waves that collide with the ergosphere of the black hole that amplifies them. Go to see the Kurzsegart video about it, they explain it very well
14:52 She's basically saying you can see front and back of the blackhole at once cause the light don't follow general rule of straight path because of immense gravity, Jaby 😁
I play this game called Elite: Dangerous where you basically just spend a bunch of time exploring the Milky Way. They did a really good job with a lot of the planets and stars, but what impressed me the most was the black holes. You can to travel to any of them in our galaxy, including the super-massive one in the center of the Milky Way, and view the lensing effect. It's absolutely mind blowing. Luckily for you as the player, they don't allow for you to get close enough to fall into one.
Isn't that the game with Fuel Rats? Because that is an awesome community to exist in games. Usually something like that, is not found in game communities.
6:59 The event horizon is basically put a smear of lights streched by balck hole's pull but also not sucked inside of it. The gravity is so strong that light bends its path in event horizon to give the ring-like shape to it. If we were to destroy this which is by the help of angular momentum i.e. the light will just go its way but the gravity will still be there. That'd mean in vastness of space and its vaccum without a event horizon, black hole is literally a hole in space. You wouldn't notice its there untill you fall into it or if you're facing a brighter half of a galaxy and you see a hole in the space, then you realize there's a blackhole. Or if you see stars in a sphere between nothingness of space, you've found a wormhole
He's talking about the picture of the accretion disk around M87 and Sagittarius A* super massive black holes (at the centres of Messier 87 and Milky Way galaxies respectively) that were imaged by the Event Horizon Telescope...
2:00 The talk of the sun being some large number of nuclear bombs going off every second led me to think of this: the sun is huge. Smack in the center of the sun, where fusion runs the fastest because the pressure is highest, the power production is a few hundred watts in every cubic meter, maybe as high as a thousand. That power density is extremely low. 4:30 Sufficiently far away from a black hole, the gravitational situation is the same as with any star. It would be a useless exercise, but one could put a Dyson sphere around a black hole the same as with a star. If there's an accretion disk, it might interfere with the Dyson sphere. 8:50 Yes, the real reason one can't escape a black hole once inside the event horizon is that into the black hole is forward in time. Escaping a black hole entails a spacelike trajectory -- going faster than light.
4:45 yes. it would be pointless, but yes, you could. black holes are just gravity wells, like a planet or star. things can orbit them, meaning if you can build a dyson sphere, you could build one around a black hole. the cost would be immense and you'd get nothing for it, since the point of a dyson sphere is to absorb the light coming off a star and convert it to electricity, and black holes famously don't give off light. the other option for a black hole is to surround it with mirrors. that you can actually get something out of by shooting lasers in and boosting their energy by stealing from the black hole. kurzgesagt has another video on that, the black hole bomb.
Man , she is brilliant that i can say. The way she explained about Fusion and Fission is great. I am attracted to her intelligence. If i got a girlfriend like her, we would daily talk and argue about all the science stuff .
So a black hole pulls you towards a singularity but since time and space is switched (and time is infinitely slowing down for you due to moving faster than the speed of light) you will never get to it because the singularity is in the future. So what I understand, you are either trapped for nigh infinity, or get deleted from our known space time.
Things like this that are technically possible, but never should happen because of very coincidental rules makes me think something or someone is responsible for this. I would really love to know what is this mysterious force responsible for it keeping such a chaotic paradoxical situations from happening
And thus breeds the search for the "Theory of Everything" million dollar prize. The joining of Quantum Mechanics and Theory of Relativity. Just what is gravity? I had my thumb on it being a WIMP since it fits the description but you'd think we'd detect it by now. CERN building an add-on to the LHC is going to be nuts, I hope it proves some things we only theoretically think of.
Breaking the event horizon feels like when you do something with precise timing in a game to glitch it in some way,so breaking it would be like an IRL glitch as crazy as it sounds. Think like that makes it seem like where actually living in a huge game
8:40 This issue of "Naked Singularity" was surmised by Sir Roger Penrose in his "Cosmic Censorship Hypothesis", where he postulated that a "Naked Singularity" cannot exist in nature. There has been debate about the issue of "Naked Singularity" between Sir Roger Penrose and Stephen Hawking, but all the evidence in the current astronomical observations has held this hypothesis as true.
4:15 yes I heard theory in which entire blackhole is covered and object is thrown into that cover of blackhole. And blackhole throws that object and keeps going back and forth. ♾️
the whole idea is a dyson sphere made of mirrors around a black hole. shoot a laser in and as the laser photons are eaten they accelerate and bump off other mirrors transferring kinetic energy into heat and light. (very much in the theoretical stage though)
I recently saw Veritasium's video about how black holes work, and it went very in-depth on the whole "the singularity is in the future" statement. Einstein's field equations tell you how space-time is bent by a mass and the difference between two events near the mass, called the "spacetime interval." We visualize this bending using a sort of map that scientists call a "Penrose diagram," which shows us everything we can influence or could influence us: it's a sort of diamond shape with the infinite future on top, the infinite past on the bottom, and infinite distance off to the sides. By convention, the diagram is scaled such that light always travels at 45-degree angles from the horizontal. If you draw two light rays out from a point in the diagram towards the top, the space between those rays represents everything you could hope to influence, as in order to influence something outside that cone, you would need to travel faster than light, which is just not possible. Similarly, if you draw light rays toward the past, the light cone that you reveal represents everything that could influence you. When we add a black hole to the diagram, we represent it as an inverted triangle extending from the top left. The black hole's singularity is at the top of this inverted triangle, it's a final moment in time for anything that crosses the event horizon. That's the reason the singularity is in the future, when something crosses the event horizon, the only future it has is to meet the singularity. But something interesting happens when you look at the bottom of the inverted black hole triangle. At this point, your entire future is within the black hole, but there is no past in the universe that could affect you, so, what's in this past light cone? Well, when we draw that area, we end up with a white hole, a black hole's opposite, where if you are inside it, you have to be ejected off to the right into the universe. However, you could just as easily be ejected to the left, so what's over there? Well, it's another universe, parallel to our own. Keep in mind, this is what we have inferred just from the simplest possible solution to Einstein's field equation, and it already describes a black hole, a white hole, and two universes. It would be like someone laid out a coordinate system over just the northern hemisphere of earth, and someone else came along and said "this is fine, but mathematically, lattitudes can be negative, so there's an entire southern hemisphere we're missing. Oh, and more than that, there's a second Earth." The real crazy part is that this discussion gets even more insane when we consider that black holes are spinning. Yes, for all their weird properties, black holes are even more screwed up than we give them credit for. If you take the solution to the field equations for a spinning black hole and take it as far as it will go, you end up revealing wormholes, infinite parallel universes, and anti-verses where gravity pushes instead of pulls. This is called "maximal extension" and it involves way too much mathematics for my migraine-prone brain. But needless to say, it is all very fascinating.
wow thats so insane to me.. i genuinely had no idea that u could destroy the event horizon. that's so nuts! imagining the singularity still being there just without its vacuum
@@josef-ralfdwerlkotte8333 No, we would need dyson spheres around a few stars to have enough energy. I'm not even sure humans will last long enough to build one.
Yeah I didnt understand 7:00 either. If the singularity is still there, where did the space -time warp go? The pull is still there, and If it's strong enough to still spaghetiffi you, ... idk. This hurts my brain. If you can take away the even horizon and fly around the singularity no problem, why is there an event horizon to begin with? What is it's purpose? I guess that's just what happens naturally after a supernova. But if it gets 'out of control' in terms of speed then I guess it eventually would simply break apart.
in interestellar, cooper doesnt actually go inside of the black hole but just in the limit of the songularity were the tesseract is, yeah that thing they speak about in avengenrs, humans put this think that uses the black hole as some kind of conduit, but cooper is inside of some sort of installation.
1. I wonder if the reason we don't see much antimatter is that most all of it is wrapped up in black holes. If that is the case.... why? 2. Yes, you could put a Dyson Sphere around a black hole, as long as it was outside the Schwarzschild radius. The Schwarzschild radius of a single solar mass is about 2 miles, while the radius of the sun is ~430,000 miles. As long as the Sphere could handle the gravitational pull of the origional star, and as long as the black hole is not feeding and causing an accretion disk which would bombard the Sphere with radiation from the inside, it would be easier to builld the Sphere around the black hole because it wouldn't have to worry about the radiation from the star and the gravity would be the same at that radius.
Entropy does not decay, it grows with time! The net effect of everything in the universe is always more disordered than the cause, which orients and drives the arrow of time
Naked singularity would act kind of like a planet than a region of highly dense space like a black hole. You could get an inch from the singularity and feel no effects, but as soon as you touch it, death. You can put a dyson around a black hole, would need a ridiculously powerful magnetic field to stabalize the position though. Black holes are physical regions of space, or rather think of it like a 3D hole that was poked into the fabric of apace time.
Fact check 1. Black holes do have matter, they do have mass. It's just focused into really really tiny point which makes it have unbelievable gravity and gobble up everything that comes close enough to it. 2. Total entropy always keep increasing. With each second passing in time entropy is alway rising and you cannot decrease it.
I thought entropy was based on chance. And that it was simply very unlikely for entropy to go back, but still physically possible. Its simply that the positions of particles to not be chaotic are very little. There are more positions of them being chaotic. However its not really impossible for the total entropy to decrease, its simply very very unlikely that probably not even the human race would observe it naturally. These are minor details but I believe are very important to seperate, between something being impossible to happen (0%) and something that still is physically capable of happening even if its very unimaginably low.
One thing is clear: You cannot count or assume anything on the basis of time which is based on earth 🌎 rotation... Just like earth, many planets as well as Stars and blackholes rotates... so one cannot count or time the perfect incidents that will happen in the future or happened past ❤
Hear me out: What if black holes are, basically, like bus stops. The black holes in the middle of galaxies are sucking IN/UP galaxies and will spit them out through a different black hole billions of light years from where WE know our galaxy to generally be. The black holes continuously ti poss through time and to the black holes and the universe it’s no big deal and takes no strain nor time to do it all, but from the human perspective and our perception of time the process takes BILLIONS and TRILLIONS of years to complete so we will never know it’s been done… unless we leave clues behind before our ultimate demise i.e. cave drawings that give clues to constellations that do not match the current solar system (not exactly).
You can build a dyson sphere around a black hole as long as it's above the event horizon and can withstand the gravity. If we did that we would have effectively an infinite power generator by taking advantage of the penrose process and superradiant scattering.
The thing about the singularity in a black hole is it’s really an artifact of the mathematical model of general relativity. The model predicts an infinitely dense point, but that doesn’t mean infinitely dense things actually exist in reality, it just means that general relativity as a model is incomplete when it comes to extreme densities and gravity. It’s similar to how quantum physics and general relativity are actually currently incompatible with each other on extreme scales where the distances are tiny but the energies and gravity are massive. So basically what the very center of a black hole “is” is almost certainly not literally something that is infinitely dense and zero size but rather some other type of object that we need something like a unified quantum theory of gravity in order to better describe. Black holes definitely exist, so event horizons exist, but the true nature of the core object where we predict a singularity to be isn’t yet known. On a related note, when the video says that “revealing a naked singularity breaks physics”, it’s not actually anything so apocalyptic as they make it sound. All that would really mean is, since we don’t know what the singularity actually is in reality because our model of relativity is incomplete, we can’t predict what it would look like or how it behaves. It doesn’t “break the universe” because the universe couldn’t care less how we mathematically try and describe it, so revealing a naked singularity would just mean the singularity and universe just continue chugging along doing whatever it is they do and we would have something new to observe that might help fill in some of the gaps in our predictive model.
8:46 Many may think this is counter-intuitive, nonsense, and even stupid. But there's a good reason to say that. The key of this is pretty methodic and even sort of obvious. The thing is that a massive object, as many are told, bends spacetime around them towards its center. Note that key implication there. Space-TIME. Time is defined in GR (General relativity) as a dimension like the other 3. With the only exception that you can only travel forward at a fixed speed. Hence, the position, movement, speed and acceleration vectors can be expressed as in a coordinate system: Like with an arbitrary point being A = (X, Y, Z, T). Space is the set of dimensions X, Y, and Z, that are perpendicular to T; Time. So, when a massive object bends spacetime, not only X, Y and Z vectors are bent towards the black hole, but we also HAVE to include T. The time "Movement" vector, wich is our perception of time running, is BENT towards the center of the object. This is why we fall. We were initially not moving, but a component of our direction in time, which we can't stop, projects to space so we are forced to move and fall. In a black hole, this bending is put to the extreme: Past the event horizon of a black hole, spacetime tilts at MORE than 45 degrees, a situation elsewhere never reached, which means that most of our time vector, (If we represent it horizontally) now projects to a *vertical* line, which was previously a direction through space. This is why time and space *seem to swap their roles.* This way, we can state for an observer that has crossed the event horizon, that his time vector now goes in a direction through space, and one of his space dimensions is bent, it has "Collapsed" in a direction previously corresponding to time. Our forced movement sends us to the singularity. But now, we can't see it, just like we can't see our future. For the falling observer, the singularity is at his future. And the event horizon, the way to escape that was behind him, is now "Behind" in his *time* dimension, it's in his *past.* I know this was long but if anyone understands it better, I'm glad it worked. >w
So the black hole event horizon is kind of like a blister. You think you should pop it but its there to protect the forming skin underneath and when you pop it, it is exposed and is so painful.
My general questions are: Why does a collision of 2 mass rich objects create something infinite? Wouldn't it just be the high mass, not letting particles escape, except if they reach a specific speed treshold? Why do particles escape and the black hole shrink otherwise, if its mass is infinite? What is gravity? Why does a lot of mass suddenly start pulling you towards it? Why can it bend time?
Just remember the infinite density and infinitely small size of a singularity is only true in math. Our math shows it as being infinitely dense and infinitely small, but that's not how the universe works.
I would sign up voluntarily to experience spaghettification, if we had a method of news escaping a blackhole. Like that sensation on future past and present, while turning to spagehtt like thats my life goal :)
Ever since I first learned about black holes and just how massive they can get, I always wondered if a black hole in another version of the Universe somehow blew apart and _that_ is what the Big Bang that birthed our Universe was. And that the laws of physics, space itself and time itself of the previous Universe were either very different or perhaps even identical - and that's why ours is the way it is; because everything previous got messed up until finally everything settled back down into a sense of order again, and maybe that order is now different (like for instance, the previous Universe time moved in the opposite direction than it does for us - you are created seemingly at random out of atoms in the ground, as an old being and slowly age younger and younger until your cells combine into a single cell which itself slowly "undoes" itself back into separate atoms in the ground). Although if that's the case, then that begs the question "what _the fuck_ could happen to a black hole THAT big to actually cause it to blast apart?!"
Its interesting, black holes have an electric charge, and thus generate a magnetic field, and for one so massive as Sagittarius A* at the center of the Milky Way its got one as big as the entire galactic disc, or bigger but only exerting useful force up to that distance given how slow orbits are out there. Considering there is no true non-magnetic object in the universe, that would imply that the Milky Way, and any spiral galaxy for that matter, is held together by the massive electromagnetic power of the black hole at its core, and likely helped by nearby supermassive objects magnetically aligned with it in the galactic core, like how stacking two identical magnets on top of each other nearly doubles the magnetic field strength. So the reason galaxies are held together is because electromagnetism is the single strongest fundamental force of the entire universe. Part of me thinks we just haven't studied all the effects of electromagnetism enough to realize that it might be the source of the strong and weak nuclear forces and perhaps a component of gravitational force, because if that's the case then I'm thinking we've probably had a unified field theory for decades and just didn't realize it XD
way more than 10000 nukes per minute. it is in fact 15 billion nukes a SECOND yes you can build a Dyson sphere around a black hole. just not close to its event horizon or its accretion disc. it is not the weight of space time. its the weight of the mass inside the black hole pulling in space time.
I once heard a good explanation from NDT on how to imagine a black hole. Think about a hole, just any hole. Through a paper, through atmosphere, through walls, through Earth itself. But a hole is possible to comprehend by us in our spacial reality via only two dimension. If you cut a hole in a paper, things will fall from one side to another, and we can say it's gone from one side of the hole to other. It's true in any caseof hole created, we can only see objects going from one side and popping out the other, in 2 sides or dimensions. Now image a whole in three dimensional space. Well, you can't, coz we aren't able to explain where or what the other side of that 3D hole is. This is what exactly is a black hole, a 3 dimensional hole in fabric of space, where we can't figure out where does the matter going in will pop, as we cannot comprehend the other side of it. As far as I'm knowledgeable, the matter entering the black hole will pop out in another dimension, if we go by the rule of above analogy. Hope this helps to understand. Cheers.
Time dilation is false though, so is space time curving, the black hole doesn’t warp you to the future. Atomic clocks use light, the faster you go the further the light goes to keep up with you, longer ticks, faulty clock. You need to compensate.
If you are interested, there's a couple super interesting universe videos that you might like: Strange Matter (super scary) and a Dark Star - no not the Star Wars one but different. Both hypothetical based on physics. Oh and a white hole - which has been proposed as the start of the big bang and/or wormhole to a parallel universe. Black holes are hard to wrap your mind around because they defy physics and go right into the weird world of quantum mechanics. I think my fav black hole phenomenon is blazars, which are quasars but their jets are pointed directly at us, unlike the imaged M87 black hole we got from the Event Horizon telescope array. Crazy to imagine that they can be so bright that their luminosity can be more than an entire galaxy. The thing that bothers me is that we don't have the same amount of matter and anti-matter in the universe. How is such a thing possible? To go on your question about a Dyson Sphere, the more likely superstructure is a Dyson Swarm - and by all estimates would need us to cannibalize Mercury, Venus, and Mars along with the asteroid belt to make it a reality. Which would require more research into self-replicating robots and a LOT of time. But hey, gotta get to a Type 2 civilization right?
Its actually easier to surround a black hole with a dyson sphere (or more precisely dyson swarm) than it is to surround a star... that is because black holes are much much smaller.
Yes you could build a dyson sphere around a black hole, black holes don't suck things in, they just have gravity from their mass, so as long as you build it in a stable orbit around a black hole it would be fine. A black hole with 1 solar mass would have the same gravity as our sun so if we could build one around our sin we could with a black hole too.
So theoretically if you can somehow remove those particles and that radiation from the black hole and somehow speed up the process of the breakdown it'll be possible to kill it
a black hole is filled with matter but that matter has just collapsed in on itself and gravity and electro magnetism have taken full hold so compressed and so absolutely maxxed out on extremes as far as environment and conditions are concerned that physics just break down
Let me try to explain what they meant by creating a naked singularity. (Take youtube comments with a grain of salt) Blackholes spin so fast with so much mass that they literally drag space-time along around with them. At a certain threshold this rotation of space-time itself moves faster than the speed of light, meaning it is literally impossible to stand still in that region. Even light traveling the other direction is dragged backwards. This is called the ergosphere. But if the power of the ergosphere becomes even stronger than the space-time being dragged into the black hole, then space-time will start to collapse into the black hole bellow the speed of light. At that point, light could actually escape it. It’s literally escaping the black-hole not by moving faster than light, but moving space-time itself out of the black hole faster than light. But the faster black holes spin, the harder it is to drop anything into it, so it might be impossible to overfeed it this way.
We are not actually destroying anything, since event horizon is just one of the gravitational effect of the singularity itself not an actual matter. So even if we are successful to destroy(which i don't think we can) we would still not anything since singularity itself has no volume on its own and exists in future. Also It has infinite density which would render its gravitational effects(just on smaller regions now) still dominating. So a person falling would experience its effect going through future but would not be able to see anything even after inside it.
I feel like Black holes pierce the fabric of our Universe and the reason Physics break inside them is because you're essentially in another Universe once you enter a Black hole, therefore completely different rules and physics apply.

your comment doesn't matter to jaby
Basically, our universe works around the fabric created from space and time. Gravity bends this fabric. But if something has infinite gravity, it infinitely bends the fabric, or in other words, it breaks it. This means there is no meaning to space or time, and the idea that the singularity is in a place is the same as the idea that it is in a time- it just doesn't make sense! Fortunately, black holes allow us the jomo (joy of missing out) effect of not knowing how this works. But here comes the point of experiment 5- if you are able to make a singularity push things away on the same level as it pulls them in, there is no event horizon, because light can escape at any point. But this mean the broken fabric is shown for all to see. The point Kurzgesagt made, is that we don't know what we'll see, since it goes against everything in physics, and yet it is physically able to exist. It is like how imaginary numbers work. We know there is no square root of a negative number, and yet we know it can exist because we can make predictions where the square root of -1 actually functions in mathematical equasions.
The only thing that sucks about Kurzgesagt is how they try to make things simplistic and it can be misunderstood because of that. But it's a good jumping off point to understand which is why I like watching them. A lot of these things require some backstory information to set it up and without making a freaking docu-series, we get this. Going into it with a frame of reference makes it a lot easier to get. PBS Space Time is a channel I go to for a deeper dive into these things.
@@Timmycooit’s a double edge sword,make it too complex and no one understands sh-t,make it too simple and you lose the grasp of the details on what something actually is. Just them being able to bring the thought of these concepts for more people is enough for me.
@@TimmycooWell people shouldnt use this channel as their only source of information. These simplified channels exist to boost your curiosity and the interested people would look up more into it online or ask their teachers some questions and so on.
Spacetime is considered to be a "fabric". It isn't created from space and time. It is "spacetime". Gravity doesn't bend spacetime. Gravity IS the curvature of spacetime. There is no force of gravity in this model. Black holes don't have infinite gravity, nor infinite mass. They are as massive as the matter that "fell in" minus whatever they may have radiated away (I don't know if that's been observed yet or not, above my pay grade of 0 lol). Astrophysicists can tell you the mass of a given black hole.
Singularities do not exist as physical objects. There is not reason to believe they do exist. The math describes the black hole. It isn't the black hole itself. The problem is quantum mechanics and general relativity don't play nice.
I would love to see more reactions to Kurzgesagt! There is so much cool, fun, and headache-inducing content worthy of being reacted to!
One of my personal favorites is "The Egg," which is their narration (and visualization) of a short story by the same name.
7:19 you can image this one as looking a glass full of water from its side and strring the water with a spoon faster and faster. The faster the spin gets, the smaller the tube of distortion gets. Same applies to the black holes. The faster its spin gets, the smaller the even horizon gets. And in this video, he refers to a point that the spin is so extreme that the tube of distortion becomes just a line (so the event horizon completely dissolves because the warping of spacetime one dimensional (a line) that goes towards to dimensionless singularity (a point).
Also you can visualize the time and space gets reversed by thinking a sheet of elastic plane, one side red other side blue, which starts to warp by a singularity that causes the image we all have seen online as the one dimension reduced version of the geometry of a blackhole. Then, you try to imagine the region of spacetime warping inside the event horizon becomes so drastic, it turns the spacetime (elastic sheet, one side red and the other side blue) inside out, which is represented by the red side becomes blue and the blue side becomes red when past the event horizon so that an object falling into a blackhole travels though space and time but much more through than time as it gets closer and when it hits the event horizon, it becomes kinda stationary in space and now it travels much more through time rather than space. So it doesn't fall through space per se, it falls through time that point on. It falls to future.
Since space and time switch roles, you would be able to move throughout time (inside the event horizon) whilst you could only partially move in only one direction (towards the singularity).
4:20 Actually yes. It's call Black Hole Bomb and can release more energy than all the stars of a galaxy combined in several million years. Kurzsegart did a video about that, you should see that, it's very interesting
the penrose sphere or as ppl like to call it the black hole bomb, love that vid
very interesting and a great follow-up to this video; because technically it would provide another way to destroy a black hole.
@@johnniequinn3215 Actually no, it doesn't destroy the black hole, it just release an enormous amount of energy. The black hole is completely uneffected
@@fabriziobiancucci7702 Where does the enormous release of energy come from? If it feeds off of the black hole to generate the explosion, then that extra energy is the bleed off of mass from the black hole itself
@@johnniequinn3215 It doesn't work like that. The energy comes from electromagnetic waves that collide with the ergosphere of the black hole that amplifies them. Go to see the Kurzsegart video about it, they explain it very well
14:52 She's basically saying you can see front and back of the blackhole at once cause the light don't follow general rule of straight path because of immense gravity, Jaby 😁
I play this game called Elite: Dangerous where you basically just spend a bunch of time exploring the Milky Way. They did a really good job with a lot of the planets and stars, but what impressed me the most was the black holes. You can to travel to any of them in our galaxy, including the super-massive one in the center of the Milky Way, and view the lensing effect. It's absolutely mind blowing. Luckily for you as the player, they don't allow for you to get close enough to fall into one.
Isn't that the game with Fuel Rats?
Because that is an awesome community to exist in games. Usually something like that, is not found in game communities.
@@WickederDrake37 yes it is! They're amazing, and I've actually been considering joining them!
This is why they say that math is the language of the universe. What the universe wants to say to us can only be understood through maths.
So black holes are the literal Spaceball meme
"when will now be then"
I really enjoyed this segment with Amber.
I hope she comes back more frequently.
A blackhole will just delete my history. Can i throw my search history into it
Wow 4:35 somebody who can challenge jaby's intellect, u earned respect. Jaby saw and it backfired badly 11:36, because he didn't get it
MATH AND SCIENCE AT THE SAME TIME?!?!?!?!?
THIS IS HEAVEN!!!!!!!!!!
I love that design 10:52
A boack hole is small, it's the event horizon that's big.
4:20 Ah... the Penrose Sphere. 😎
6:59 The event horizon is basically put a smear of lights streched by balck hole's pull but also not sucked inside of it. The gravity is so strong that light bends its path in event horizon to give the ring-like shape to it. If we were to destroy this which is by the help of angular momentum i.e. the light will just go its way but the gravity will still be there. That'd mean in vastness of space and its vaccum without a event horizon, black hole is literally a hole in space. You wouldn't notice its there untill you fall into it or if you're facing a brighter half of a galaxy and you see a hole in the space, then you realize there's a blackhole. Or if you see stars in a sphere between nothingness of space, you've found a wormhole
He's talking about the picture of the accretion disk around M87 and Sagittarius A* super massive black holes (at the centres of Messier 87 and Milky Way galaxies respectively) that were imaged by the Event Horizon Telescope...
Can we talk about the ost. Shit hits like a 18th century tragedy theme.
THIS VIDEO MAKES A PERFECT REPRESENTION
2:00 The talk of the sun being some large number of nuclear bombs going off every second led me to think of this: the sun is huge. Smack in the center of the sun, where fusion runs the fastest because the pressure is highest, the power production is a few hundred watts in every cubic meter, maybe as high as a thousand. That power density is extremely low.
4:30 Sufficiently far away from a black hole, the gravitational situation is the same as with any star. It would be a useless exercise, but one could put a Dyson sphere around a black hole the same as with a star. If there's an accretion disk, it might interfere with the Dyson sphere.
8:50 Yes, the real reason one can't escape a black hole once inside the event horizon is that into the black hole is forward in time. Escaping a black hole entails a spacelike trajectory -- going faster than light.
4:45 yes.
it would be pointless, but yes, you could. black holes are just gravity wells, like a planet or star. things can orbit them, meaning if you can build a dyson sphere, you could build one around a black hole.
the cost would be immense and you'd get nothing for it, since the point of a dyson sphere is to absorb the light coming off a star and convert it to electricity, and black holes famously don't give off light.
the other option for a black hole is to surround it with mirrors. that you can actually get something out of by shooting lasers in and boosting their energy by stealing from the black hole. kurzgesagt has another video on that, the black hole bomb.
Man , she is brilliant that i can say. The way she explained about Fusion and Fission is great. I am attracted to her intelligence. If i got a girlfriend like her, we would daily talk and argue about all the science stuff .
So a black hole pulls you towards a singularity but since time and space is switched (and time is infinitely slowing down for you due to moving faster than the speed of light) you will never get to it because the singularity is in the future. So what I understand, you are either trapped for nigh infinity, or get deleted from our known space time.
8:40 "Life has many doors, Ed-boys!"
yo they just released a video 'you're a dream of the universe', this will expand on the discussion you guys had after the reaction...
Things like this that are technically possible, but never should happen because of very coincidental rules makes me think something or someone is responsible for this. I would really love to know what is this mysterious force responsible for it keeping such a chaotic paradoxical situations from happening
Kang😅
And thus breeds the search for the "Theory of Everything" million dollar prize. The joining of Quantum Mechanics and Theory of Relativity. Just what is gravity? I had my thumb on it being a WIMP since it fits the description but you'd think we'd detect it by now. CERN building an add-on to the LHC is going to be nuts, I hope it proves some things we only theoretically think of.
Breaking the event horizon feels like when you do something with precise timing in a game to glitch it in some way,so breaking it would be like an IRL glitch as crazy as it sounds. Think like that makes it seem like where actually living in a huge game
@@onesmileybaldy8303 A lot about the universe makes it feel like a game - where there's glitches lol.
8:40 This issue of "Naked Singularity" was surmised by Sir Roger Penrose in his "Cosmic Censorship Hypothesis", where he postulated that a "Naked Singularity" cannot exist in nature. There has been debate about the issue of "Naked Singularity" between Sir Roger Penrose and Stephen Hawking, but all the evidence in the current astronomical observations has held this hypothesis as true.
4:15 yes
I heard theory in which entire blackhole is covered and object is thrown into that cover of blackhole. And blackhole throws that object and keeps going back and forth. ♾️
the whole idea is a dyson sphere made of mirrors around a black hole. shoot a laser in and as the laser photons are eaten they accelerate and bump off other mirrors transferring kinetic energy into heat and light. (very much in the theoretical stage though)
Nice to have a scientist react to science content.
Imagine building a Dyson-Sphere around a Quasar.
I recently saw Veritasium's video about how black holes work, and it went very in-depth on the whole "the singularity is in the future" statement. Einstein's field equations tell you how space-time is bent by a mass and the difference between two events near the mass, called the "spacetime interval." We visualize this bending using a sort of map that scientists call a "Penrose diagram," which shows us everything we can influence or could influence us: it's a sort of diamond shape with the infinite future on top, the infinite past on the bottom, and infinite distance off to the sides. By convention, the diagram is scaled such that light always travels at 45-degree angles from the horizontal. If you draw two light rays out from a point in the diagram towards the top, the space between those rays represents everything you could hope to influence, as in order to influence something outside that cone, you would need to travel faster than light, which is just not possible. Similarly, if you draw light rays toward the past, the light cone that you reveal represents everything that could influence you.
When we add a black hole to the diagram, we represent it as an inverted triangle extending from the top left. The black hole's singularity is at the top of this inverted triangle, it's a final moment in time for anything that crosses the event horizon. That's the reason the singularity is in the future, when something crosses the event horizon, the only future it has is to meet the singularity. But something interesting happens when you look at the bottom of the inverted black hole triangle. At this point, your entire future is within the black hole, but there is no past in the universe that could affect you, so, what's in this past light cone? Well, when we draw that area, we end up with a white hole, a black hole's opposite, where if you are inside it, you have to be ejected off to the right into the universe. However, you could just as easily be ejected to the left, so what's over there? Well, it's another universe, parallel to our own. Keep in mind, this is what we have inferred just from the simplest possible solution to Einstein's field equation, and it already describes a black hole, a white hole, and two universes. It would be like someone laid out a coordinate system over just the northern hemisphere of earth, and someone else came along and said "this is fine, but mathematically, lattitudes can be negative, so there's an entire southern hemisphere we're missing. Oh, and more than that, there's a second Earth."
The real crazy part is that this discussion gets even more insane when we consider that black holes are spinning. Yes, for all their weird properties, black holes are even more screwed up than we give them credit for. If you take the solution to the field equations for a spinning black hole and take it as far as it will go, you end up revealing wormholes, infinite parallel universes, and anti-verses where gravity pushes instead of pulls. This is called "maximal extension" and it involves way too much mathematics for my migraine-prone brain. But needless to say, it is all very fascinating.
Ambre is the dream girl of every nerd like me. ❤
wow thats so insane to me.. i genuinely had no idea that u could destroy the event horizon. that's so nuts! imagining the singularity still being there just without its vacuum
Well it's just theory. We can't actually do it.
@@evylrunewe can try
@@josef-ralfdwerlkotte8333 No, we would need dyson spheres around a few stars to have enough energy. I'm not even sure humans will last long enough to build one.
@@evylruneA game theory.. Aaaaand cut 😢
Yeah I didnt understand 7:00 either. If the singularity is still there, where did the space -time warp go? The pull is still there, and If it's strong enough to still spaghetiffi you, ... idk. This hurts my brain. If you can take away the even horizon and fly around the singularity no problem, why is there an event horizon to begin with? What is it's purpose? I guess that's just what happens naturally after a supernova. But if it gets 'out of control' in terms of speed then I guess it eventually would simply break apart.
in interestellar, cooper doesnt actually go inside of the black hole but just in the limit of the songularity were the tesseract is, yeah that thing they speak about in avengenrs, humans put this think that uses the black hole as some kind of conduit, but cooper is inside of some sort of installation.
3:37 maybe bcz bana has the smallest naturally found radioactivity
Jaby's t-shirt says it all about the black hole video!😂
Them : how does a singularity work
Me as a physicist : how does a singularity work
I now know where all my lost ball point pens have gone
1. I wonder if the reason we don't see much antimatter is that most all of it is wrapped up in black holes. If that is the case.... why?
2. Yes, you could put a Dyson Sphere around a black hole, as long as it was outside the Schwarzschild radius. The Schwarzschild radius of a single solar mass is about 2 miles, while the radius of the sun is ~430,000 miles. As long as the Sphere could handle the gravitational pull of the origional star, and as long as the black hole is not feeding and causing an accretion disk which would bombard the Sphere with radiation from the inside, it would be easier to builld the Sphere around the black hole because it wouldn't have to worry about the radiation from the star and the gravity would be the same at that radius.
Black holes are just the place where things go when the simulation decides to empty it's Recycle Bin.
“Can you put a Duden sphere around a black hole?”
Kerzgesat actually did a video on that, Titled: The black hole bomb
I think.
Entropy does not decay, it grows with time! The net effect of everything in the universe is always more disordered than the cause, which orients and drives the arrow of time
We need more of these . ❤
Nature is fascinating
Naked singularity would act kind of like a planet than a region of highly dense space like a black hole. You could get an inch from the singularity and feel no effects, but as soon as you touch it, death.
You can put a dyson around a black hole, would need a ridiculously powerful magnetic field to stabalize the position though.
Black holes are physical regions of space, or rather think of it like a 3D hole that was poked into the fabric of apace time.
Fact check
1. Black holes do have matter, they do have mass. It's just focused into really really tiny point which makes it have unbelievable gravity and gobble up everything that comes close enough to it.
2. Total entropy always keep increasing. With each second passing in time entropy is alway rising and you cannot decrease it.
Non of that is true or can be proven
I can say its made out of unicorn farts and that would be as true as what you just said !
@@chrishernandez8504 read up on it then jackass
I thought entropy was based on chance. And that it was simply very unlikely for entropy to go back, but still physically possible. Its simply that the positions of particles to not be chaotic are very little. There are more positions of them being chaotic.
However its not really impossible for the total entropy to decrease, its simply very very unlikely that probably not even the human race would observe it naturally.
These are minor details but I believe are very important to seperate, between something being impossible to happen (0%) and something that still is physically capable of happening even if its very unimaginably low.
One thing is clear:
You cannot count or assume anything on the basis of time which is based on earth 🌎 rotation...
Just like earth, many planets as well as Stars and blackholes rotates... so one cannot count or time the perfect incidents that will happen in the future or happened past ❤
Hear me out: What if black holes are, basically, like bus stops. The black holes in the middle of galaxies are sucking IN/UP galaxies and will spit them out through a different black hole billions of light years from where WE know our galaxy to generally be. The black holes continuously ti poss through time and to the black holes and the universe it’s no big deal and takes no strain nor time to do it all, but from the human perspective and our perception of time the process takes BILLIONS and TRILLIONS of years to complete so we will never know it’s been done… unless we leave clues behind before our ultimate demise i.e. cave drawings that give clues to constellations that do not match the current solar system (not exactly).
You can build a dyson sphere around a black hole as long as it's above the event horizon and can withstand the gravity. If we did that we would have effectively an infinite power generator by taking advantage of the penrose process and superradiant scattering.
The thing about the singularity in a black hole is it’s really an artifact of the mathematical model of general relativity. The model predicts an infinitely dense point, but that doesn’t mean infinitely dense things actually exist in reality, it just means that general relativity as a model is incomplete when it comes to extreme densities and gravity. It’s similar to how quantum physics and general relativity are actually currently incompatible with each other on extreme scales where the distances are tiny but the energies and gravity are massive.
So basically what the very center of a black hole “is” is almost certainly not literally something that is infinitely dense and zero size but rather some other type of object that we need something like a unified quantum theory of gravity in order to better describe. Black holes definitely exist, so event horizons exist, but the true nature of the core object where we predict a singularity to be isn’t yet known.
On a related note, when the video says that “revealing a naked singularity breaks physics”, it’s not actually anything so apocalyptic as they make it sound. All that would really mean is, since we don’t know what the singularity actually is in reality because our model of relativity is incomplete, we can’t predict what it would look like or how it behaves. It doesn’t “break the universe” because the universe couldn’t care less how we mathematically try and describe it, so revealing a naked singularity would just mean the singularity and universe just continue chugging along doing whatever it is they do and we would have something new to observe that might help fill in some of the gaps in our predictive model.
8:46 Many may think this is counter-intuitive, nonsense, and even stupid. But there's a good reason to say that.
The key of this is pretty methodic and even sort of obvious.
The thing is that a massive object, as many are told, bends spacetime around them towards its center.
Note that key implication there. Space-TIME.
Time is defined in GR (General relativity) as a dimension like the other 3. With the only exception that you can only travel forward at a fixed speed. Hence, the position, movement, speed and acceleration vectors can be expressed as in a coordinate system: Like with an arbitrary point being A = (X, Y, Z, T).
Space is the set of dimensions X, Y, and Z, that are perpendicular to T; Time.
So, when a massive object bends spacetime, not only X, Y and Z vectors are bent towards the black hole, but we also HAVE to include T. The time "Movement" vector, wich is our perception of time running, is BENT towards the center of the object. This is why we fall. We were initially not moving, but a component of our direction in time, which we can't stop, projects to space so we are forced to move and fall.
In a black hole, this bending is put to the extreme:
Past the event horizon of a black hole, spacetime tilts at MORE than 45 degrees, a situation elsewhere never reached, which means that most of our time vector, (If we represent it horizontally) now projects to a *vertical* line, which was previously a direction through space. This is why time and space *seem to swap their roles.*
This way, we can state for an observer that has crossed the event horizon, that his time vector now goes in a direction through space, and one of his space dimensions is bent, it has "Collapsed" in a direction previously corresponding to time.
Our forced movement sends us to the singularity. But now, we can't see it, just like we can't see our future.
For the falling observer, the singularity is at his future. And the event horizon, the way to escape that was behind him, is now "Behind" in his *time* dimension, it's in his *past.*
I know this was long but if anyone understands it better, I'm glad it worked. >w
I love her nerdy head 😂
My brain gets excited after watching this and jaby you are talking about infrared spectrum
So the black hole event horizon is kind of like a blister. You think you should pop it but its there to protect the forming skin underneath and when you pop it, it is exposed and is so painful.
If you want to put a Dyson Sphere around a black hole watch kurzgesagt black hole bomb video
A Black hole is a 3D hole to s
Singularity which exist outside of time just like outside of space. So no Flow of time it's all there at once.
If you watch this guy often like I do then the videos that he makes will overtime slowly start to make sense you just have to watch him more often
So basically a naked black hole is a command block which can spawn and destroy anything and everything even space-time.
Why did the cover make me think of Welt Yang from Star Rail lol
This is how you become a lovecraftian cultist.
Those who really grasp the true knowledge become insane.
My general questions are:
Why does a collision of 2 mass rich objects create something infinite? Wouldn't it just be the high mass, not letting particles escape, except if they reach a specific speed treshold? Why do particles escape and the black hole shrink otherwise, if its mass is infinite?
What is gravity? Why does a lot of mass suddenly start pulling you towards it? Why can it bend time?
Just remember the infinite density and infinitely small size of a singularity is only true in math. Our math shows it as being infinitely dense and infinitely small, but that's not how the universe works.
I would sign up voluntarily to experience spaghettification, if we had a method of news escaping a blackhole.
Like that sensation on future past and present, while turning to spagehtt like thats my life goal :)
Because you see fission release energy and fusion depending on the size of atoms it may or maynot
More more of Ambre, she is awesome...
Quotting Oppenheimer "Theory only gets us so far"
Ever since I first learned about black holes and just how massive they can get, I always wondered if a black hole in another version of the Universe somehow blew apart and _that_ is what the Big Bang that birthed our Universe was. And that the laws of physics, space itself and time itself of the previous Universe were either very different or perhaps even identical - and that's why ours is the way it is; because everything previous got messed up until finally everything settled back down into a sense of order again, and maybe that order is now different (like for instance, the previous Universe time moved in the opposite direction than it does for us - you are created seemingly at random out of atoms in the ground, as an old being and slowly age younger and younger until your cells combine into a single cell which itself slowly "undoes" itself back into separate atoms in the ground).
Although if that's the case, then that begs the question "what _the fuck_ could happen to a black hole THAT big to actually cause it to blast apart?!"
The singularity is a point in time, not a place in space
Yo, Fire God Liu Kang is far more powerful than we thought!
Its interesting, black holes have an electric charge, and thus generate a magnetic field, and for one so massive as Sagittarius A* at the center of the Milky Way its got one as big as the entire galactic disc, or bigger but only exerting useful force up to that distance given how slow orbits are out there. Considering there is no true non-magnetic object in the universe, that would imply that the Milky Way, and any spiral galaxy for that matter, is held together by the massive electromagnetic power of the black hole at its core, and likely helped by nearby supermassive objects magnetically aligned with it in the galactic core, like how stacking two identical magnets on top of each other nearly doubles the magnetic field strength. So the reason galaxies are held together is because electromagnetism is the single strongest fundamental force of the entire universe. Part of me thinks we just haven't studied all the effects of electromagnetism enough to realize that it might be the source of the strong and weak nuclear forces and perhaps a component of gravitational force, because if that's the case then I'm thinking we've probably had a unified field theory for decades and just didn't realize it XD
way more than 10000 nukes per minute. it is in fact 15 billion nukes a SECOND
yes you can build a Dyson sphere around a black hole. just not close to its event horizon or its accretion disc.
it is not the weight of space time. its the weight of the mass inside the black hole pulling in space time.
I once heard a good explanation from NDT on how to imagine a black hole.
Think about a hole, just any hole. Through a paper, through atmosphere, through walls, through Earth itself. But a hole is possible to comprehend by us in our spacial reality via only two dimension. If you cut a hole in a paper, things will fall from one side to another, and we can say it's gone from one side of the hole to other. It's true in any caseof hole created, we can only see objects going from one side and popping out the other, in 2 sides or dimensions.
Now image a whole in three dimensional space. Well, you can't, coz we aren't able to explain where or what the other side of that 3D hole is. This is what exactly is a black hole, a 3 dimensional hole in fabric of space, where we can't figure out where does the matter going in will pop, as we cannot comprehend the other side of it.
As far as I'm knowledgeable, the matter entering the black hole will pop out in another dimension, if we go by the rule of above analogy. Hope this helps to understand.
Cheers.
I think a good display of time existing simultaneously is in the watchmen mini series were dr Manhattan exist in his past our present and his future.
Time dilation is false though, so is space time curving, the black hole doesn’t warp you to the future.
Atomic clocks use light, the faster you go the further the light goes to keep up with you, longer ticks, faulty clock. You need to compensate.
we need talk about the Phillip J Fry paradox where he is his own grandfather
I understood everything!! Yayy 😂
If you are interested, there's a couple super interesting universe videos that you might like: Strange Matter (super scary) and a Dark Star - no not the Star Wars one but different. Both hypothetical based on physics. Oh and a white hole - which has been proposed as the start of the big bang and/or wormhole to a parallel universe.
Black holes are hard to wrap your mind around because they defy physics and go right into the weird world of quantum mechanics. I think my fav black hole phenomenon is blazars, which are quasars but their jets are pointed directly at us, unlike the imaged M87 black hole we got from the Event Horizon telescope array. Crazy to imagine that they can be so bright that their luminosity can be more than an entire galaxy.
The thing that bothers me is that we don't have the same amount of matter and anti-matter in the universe. How is such a thing possible?
To go on your question about a Dyson Sphere, the more likely superstructure is a Dyson Swarm - and by all estimates would need us to cannibalize Mercury, Venus, and Mars along with the asteroid belt to make it a reality. Which would require more research into self-replicating robots and a LOT of time. But hey, gotta get to a Type 2 civilization right?
Its actually easier to surround a black hole with a dyson sphere (or more precisely dyson swarm) than it is to surround a star... that is because black holes are much much smaller.
Yes you could build a dyson sphere around a black hole, black holes don't suck things in, they just have gravity from their mass, so as long as you build it in a stable orbit around a black hole it would be fine. A black hole with 1 solar mass would have the same gravity as our sun so if we could build one around our sin we could with a black hole too.
So theoretically if you can somehow remove those particles and that radiation from the black hole and somehow speed up the process of the breakdown it'll be possible to kill it
a black hole is filled with matter but that matter has just collapsed in on itself and gravity and electro magnetism have taken full hold so compressed and so absolutely maxxed out on extremes as far as environment and conditions are concerned that physics just break down
Let me try to explain what they meant by creating a naked singularity. (Take youtube comments with a grain of salt)
Blackholes spin so fast with so much mass that they literally drag space-time along around with them. At a certain threshold this rotation of space-time itself moves faster than the speed of light, meaning it is literally impossible to stand still in that region. Even light traveling the other direction is dragged backwards. This is called the ergosphere. But if the power of the ergosphere becomes even stronger than the space-time being dragged into the black hole, then space-time will start to collapse into the black hole bellow the speed of light. At that point, light could actually escape it. It’s literally escaping the black-hole not by moving faster than light, but moving space-time itself out of the black hole faster than light. But the faster black holes spin, the harder it is to drop anything into it, so it might be impossible to overfeed it this way.
well kurzgesagt posted a video now saying that we are just a dream of a dead universe.
If you fell into a black hole, you would start to see into the future and when you crossed the event horizon you would see the death of the universe.
We are not actually destroying anything, since event horizon is just one of the gravitational effect of the singularity itself not an actual matter. So even if we are successful to destroy(which i don't think we can) we would still not anything since singularity itself has no volume on its own and exists in future. Also It has infinite density which would render its gravitational effects(just on smaller regions now) still dominating. So a person falling would experience its effect going through future but would not be able to see anything even after inside it.
Watch the black hole bomb video. They talk about building around one.
I need to watch that movie Event Horizon again! 🧐
Naked singularity?… that’s the bagel, right?!👀
4:22 He already has another video about it :p
I feel like Black holes pierce the fabric of our Universe and the reason Physics break inside them is because you're essentially in another Universe once you enter a Black hole, therefore completely different rules and physics apply.
Lmao I was enjoying the science and it gives you anxiety attacks
Her voice is super cute😍
How is she part of Bill Nye's team? She said she thinks entropy is the second law of thermodynamics, and it "decays"!!!?
Naked singularities can't exist, that's all.
Wouldn’t the end of the universe destroy the black hole that exists within it? Or can the black hole escape that and exist beyond the end?
If our universe is a simulation the singularity is a bug which the creator of the simulation patched up with an event horizon
