The bit of grass on the black hole's event horizon added a bit of realism since we can never actually see the grass fall in. And the black hole on the lawn (a lawn hole?), explains why some people are always late. They just have a black hole in their yard.
And no scientists thinks that there even is a singularity, space or timewise. It's accepted as just being a mathematical artifact from the theory breaking, not a tangible thing. Though no one knows what's in there, a far more likely hypothesis seems to be some kind of object.
If Penrose’s CCC theory is correct, the Universe starts new as soon as anything reach the singularity in any black hole. From the outside, anything will seem to stop before it reaches the event horizon, but it will be time dilated, the same amount of time as the Universe will use before its time ends. Effectively time stops and ends in the black holes, and it ends outside too, in an utterly extremely distant future where mass has disappeared and only energy (photons) are left. This is because what black holes really tells us, is the end point of the Universe. Then space and time also disappears, only the energy exists, but this is what is the big bang of the next æon. So philosophically, as soon as something falls into a black hole, it will experience that time ends together with everything outside and the all the energy will form the next æon, the start of the Universe again. Seen from inside the black hole, the time of the Universe will run incredibly fast, and from the outside - inversely so. Amd btw - this all should be possible to calculate, including the total (possible) age and size of the Universe, if one assumes that the size of the singularity is one Planck lenght, not infinitely small. Yes, there is no reason to think that the singularity must be infinitely small, breaking down our mathematic understanding of the black holes and the Universe.
If time slows down the closer you get to a black hole and freezes, then shouldn't a black hole be filled with objects frozen in time around its orbit? Just like a picture you can see on all the satellites orbiting earth?
There's no "living" or "inside" a black hole. It actually is a point with no size. The event horizon is an optical illusion because time/space is compressed. This is also why the light we can see outside the "hole" is brighter, because it's all the light coming from behind the illusion, squeezed around it. More mass = bigger illusion. Note the end where we don't see the traveler fall in...because they don't. They've time-traveled to the end of the universe in the form of pure energy. (No, they don't come back out and there is no other side.)
What's wild is this is kinda how driving into a rainbow is. This happened to me once while driving from Ohio to Alaska through Canada. There was a rainbow that actually ended on the road up ahead or at least it appeared to be coming out of the road. We drove closer and closer to it, but once we got a certain distance away, it seemed like it was moving away to keep a constant distance away. Then suddenly it vanished and appeared to be the same distance behind us so we must have driven though it but never saw it. I feel like black holes are similar in some way.

Your own clock speed is always 1 second per second. You can only have a different clock speed relative to someone else. You can age more slowly than someone else if you accelerate away from them and then return to them while they remain at constant speed. Counter-intuitively, the longest travel time between two events (points in spacetime) is a straight line (geodesic).
quick question: if falling down a black hole you, from an exterior observer, spent an infinite amount of time falling, doesn't that mean the black hole will have evaporated by that time?
the infinite time dilation at the event horizon is the reason i'm convinced that anyone falling into one immediately gets obliterated by the star that formed it, still sitting there, just under the event horizon. because for all points outside if the EH, events at or below the EH cannot have happened yet. so it doesn't matter that in the reference frame of the star, it collapses just fine into a singularity. in every reference frame outside of that, it hasn't done that yet, so as you fall in and catch up to the star's frame, it should just be waiting for you there. it doesn't seem possible for the star to have collapsed into a singularity BEFORE you enter the black hole, since that is literally infinitely far away in time from you outside of the EH.
I want to watch the final episode of Star Trek Discovery again. They put the Progenitor's technology just beyond the event horizon of a black hole so no one could get to it.
I once said this: not only you won’t see yourself crossing the EH but also assuming another object is falling in front of you (for example a flashlight pointed at you) then you would still see its light even though for an outside observer it would already crossed the EH
I think of black holes as a contour map of time dilation, and as you get increasingly close to the center the contour lines get closer and closer together until you have the sphaguettification happen at the elementary particle level so that they become a more pin-like probability distribution, and in a black hole I think rather than the strong force being overcome what happens is that particles are warped enough and experience so much entropy they manage to create a more stable internal spherical configuration of in a warped pin-like state. Because of the time dilation, just a small shift can extend the pin length considerably, so particles are more like pins touching the center. But even then, causality has to be preserved, at least within this spacetime configuration, so the particles aren't really completely pin-like but conical. In the portions where time dilation is greater is has to extend itself further to obtain a spin velocity that the portions located in a spacetime with lesser time dilation can overcome with less radius, because both the angular velocity and the radial velocity at the surface of its probability distribution have to remain consistent to interact externally, even if internally it will experience a portion of it, a mass if you will, that will not be able to do so and will only be able to interact within itself normally. I believe this creates a surface where particles that decay into a black hole settle, with external pressure countered by spacetime limitations, and due to its spin like nature, it creates a new spacetime configuration that is only able to interact within its surface (or within its volume, if the black hole is a hyperspherical singularity within hyperspace).
When I saw this in the thumbnail I thought there was just a lawn and someone poorly drew over it with pitch black color in ms paint, but it actually is really that black in the video x) All practical!
i really honestly feel that time wont move differently. if i counted seconds, it would be a second long, and if the person falling into the black hole counted seconds, they would be a second long. i think the reason they would move slower and slower is because it would take more and more time for light to escape near the black hole, eventually, as you said, lengthening the wavelength aswell, less and less light would escape the black hole as they fall further in, making their image fade
You definitely should make a home theater with all the walls and floor covered with that, it would literally like you sittin on a seat floating in space
THIS IS SO COOOOOL OMIGOD This is the sort of shit I always wondered about when I first found out about black holes and some of the introductory physics related to them, it’s so crazy awesome that this is legit SCIENCE
From the point of view of external observers, nothing ever crosses the event horizon. Black holes are hollow shells. All the mass is at the event horizon or outside it.
Not a balck real hole. In case anyone wondered. Its just black in the case of no escaped light. And an explanation of the point of no return for a black hole
From the outside, doesn't the star freeze in time and never actually become a proper black hole, due the same time dilation effects that you were talking about in the video? If so, then the density is not infinite, but is actually smaller then the density of air for supermassive black holes. It only possibly gets larger in the falling frame.
This is demonstrating my mood. I’m falling and I cannot stop it from happening. It’s too wide to grab another edge and there’s no-one nearby to save me. The therapists just don’t get it.
If from an external point of view nothing ever "finish falling" into a black hole, how can they be growing in size (also from an external point of view), without having ever trully "swallowed" anything?
3:07. This is not accurate. As you approach the event horizon, the black hole would appear as a disc in front of you growing larger and larger. The moment you reach the event horizon, the disc would appear infinitely large, equivalent to a plane, so now the universe would appear cut in half, stars on one side of the plane, darkness on the other. Once you pass the event horizon, the visible universe would shrink into a disc that would become smaller and smaller as you near the singularity. You’d see that disc by looking away from the singularity. Essentially the singularity would envelope your entire view forward and back, with the visible universe shrinking to a point behind you. So you would be able to notice right when you cross the event horizon. That’s the moment the event horizon appears as a plane. You can see that in the app by adjusting your view lateral to the event horizon and positioning yourself directly at it.
I have a question. If light can't escape a black hole due to gravity, how much influence do other objects have on light? Like the moon would be miniscule, Earth would likely be similar, but what about the sun or bigger stars? Do objects shift the light we see? And if so, does that mean other galaxies and stars far away are not really in the direction we are looking, and has their light been shifted from gravity like some sort of mirror maze?
@dirceuh that's awesome. So, theoretically, if we could space travel, just getting direction would be an insane amount of math! He should do a video on that.
KAM ARIS says it best: "The significance of the passage of time, right? The significance of the passage of time. So when you think about it, there is great significance to the passage of time...there is such great significance to the passage of time."
I just love your dry humor 😂 Anyway, when an outside observer (say Alice) sees someone falling in (say Bob) slowing down, shouldn't Alice also see Bob becoming bigger? When Bob brings Einsteins light clock, Alice would see it ticks slower. But since light moves at the same speed for all observers, the distance between the mirrors of the light clock must become really big to accommodate for the slow ticks. So Alice also sees Bob smear out over the horizon. But for Bob the light clock would retain its original size. But the light clocks that already were near the horizon, seen from Bob, they would shrink again then. Since this counts for everything near the horizon, the whole thing shrinks. Until it becomes really really small, like a dot. The singularity? So conclusion: the horizon is the singularity. 😜 The difference is just the perspective.
Unfortunately everyone explaining "what it would look like falling into a black hole" forgets one important fact: Humans cant withstand acceleration above a certain point, but the closer you get to a black hole the faster you move. So in reality, youd be dead long before you reach it. The Schwarzschild Radius already accelerates at the speed of light. Once you reach the point of 5 G and above, its over. Doesnt matter the suite or ship.
We don't know whether a singularity exists at the center of a black hole, because we don't know whether our mathematical understanding of black holes actually describes what is under the event horizon, and we don't know whether points mathematically defined as being inside the event horizon even correspond to anything in physical reality. What we DO have observational testing of, though, is the approximate relation of a black hole's mass to its radius, because we have images of the accretion disks of Sagittarius A* (the Milky Way supermassive black hole) and the M87 supermassive black hole, and thus of the regions of these disks blocked out by the black holes. And this relation dictates that the average density (not considering what if anything is inside the event horizon) goes down as the mass increases, because the event horizon radius increases linearly with the mass, which means that the volume increases with the cube of the mass.
taking into account time dilation, if conditions are appropriate (speed, angle, black hole size, etc.) could you orbit a black hole just after crossing the event horizon for long enough that the black hole has a chance to evaporate and shrink around you making you exit the event horizon again eons in the future?
Just a quick reply... No paradox just poor explanation. When your clock slows down there's nothing that happens to your velocity. If anything you feel like your velocity is increasing because you're going so much further in just a few ticks. When you get close to the black hole and only one millisecond passes for each real second then you have like no time to observe that you're falling towards the singularity it's not infinite time. But not only do you get time dilation from the gravitational well but you also get time dilation from your speed. So in the time you can do something in a millisecond it takes you a real second to do that action. So before you could snap the shutter on your camera *floop* and you're already in the event horizon.
Hi Action Lab dude.. I have a decent idea for an experiment. I never really know where is best to contact you so I'll type it out here... (how is it best to send you ideas? I often think them up...) Ok here goes.. The doppler effect. You know that old experiment where an open train goes by at a moderate speed and there are musicians stood on it all playing a single trumpet note. Then of course the observer hears that classic lowering of the tone as the train goes by... What I need to know is... is it at all possible to have them play a "reciprocal " rising note as they go by and therefore cancel out the audible doppler effect? So the witnesses just hear a single stable tone as the train hoes by? I can't quite decide if it will work or not. I can imagine the doppler effect sneaking in anyway in some way.... Obviously the effect would only be available to hear stood right next to the witness. I'm kinda 50/50 on it So I'd love to see it tested! Also, a little extra on the doppler effect... I discovered this from picking up my boomerangs off the ground. When there's a a plane going over and its roughly above you, bend down to touch the ground slowly and then back up. Youll find you hear a doppler effect! Even though the plane is a couple of miles away and you are only changing the distance by three feet, that plane is also going really fast so the distance is a lot more than than it seems at first glance.... Anyway I hope you see this, I love your videos so keep up the good work! Kind regards, Ryan ;)
Huge thanks. This gonna give me ability to bring insane content about keeping our loved ones in the same "sphere of influence" haha. Golden sir. Channel never disappoints.
So if we could somehow send 1000 stars simultaneously into a black hole, we would never see them enter, right? So how do supermassive black holes actually form if relative to us, nothing actually falls in them? Would we observe the mass of the singularity to increase in my example? If so, WHEN would the singularity grow in mass?
I hope you all realize that although he speaks in absolutes, as if this is factual, it is just theoretical. No one knows if any of this is true. Enjoy the entertainment value of this.
Due to the two dimensional surface analogy, I was expecting the cartoon animation to show an astronaut approaching the black hole sideways instead of vertically
nobody talks about this black hole on the field wouldn't be black at all, but because bending the light from the opposite side it would be invisible in a sense, distorting the image you see highly.
This is the thing that kills me: If, to the external observer, it takes forever for the infalling matter to reach the event horizon, is that just an optical illusion or can the black hole actually never consume matter as far as an external observer is concerned? Because if that's the case, how can a black hole grow?
"they can't even agree on the order events happen". While this is technically true, it's important to mention that everyone always agrees on the order that causally related events happen (i.e. any two events within each others' future or past light cones).
Now there's a daughter infinitely tolerant of her father :)

I think of black holes as a contour map of time dilation, and as you get increasingly close to the center the contour lines get closer and closer together until you have the sphaguettification happen at the elementary particle level so that they become a more pin-like probability distribution, and in a black hole I think rather than the strong force being overcome what happens is that particles are warped enough and experience so much entropy they manage to create a more stable internal spherical configuration of in a warped pin-like state. Because of the time dilation, just a small shift can extend the pin length considerably, so particles are more like pins touching the center.
But even then, causality has to be preserved, at least within this spacetime configuration, so the particles aren't really completely pin-like but conical. In the portions where time dilation is greater is has to extend itself further to obtain a spin velocity that the portions located in a spacetime with lesser time dilation can overcome with less radius, because both the angular velocity and the radial velocity at the surface of its probability distribution have to remain consistent to interact externally, even if internally it will experience a portion of it, a mass if you will, that will not be able to do so and will only be able to interact within itself normally. I believe this creates a surface where particles that decay into a black hole settle, with external pressure countered by spacetime limitations, and due to its spin like nature, it creates a new spacetime configuration that is only able to interact within its surface (or within its volume, if the black hole is a hyperspherical singularity within hyperspace).
Not only can I send this cool video to my depressed scientist friend, I can also passively suggest he seek therapy lol
3:50 UNFORTUNATE FRIEND.....!!!!😂🤣
How do we know we aren't in a black hole right now?
When I saw this in the thumbnail I thought there was just a lawn and someone poorly drew over it with pitch black color in ms paint, but it actually is really that black in the video x) All practical!
i really honestly feel that time wont move differently. if i counted seconds, it would be a second long, and if the person falling into the black hole counted seconds, they would be a second long. i think the reason they would move slower and slower is because it would take more and more time for light to escape near the black hole, eventually, as you said, lengthening the wavelength aswell, less and less light would escape the black hole as they fall further in, making their image fade
Therefore... if your boss accuses you of being late for work, just point out that your time is slower than his/hers. Fixed. 😎
You definitely should make a home theater with all the walls and floor covered with that, it would literally like you sittin on a seat floating in space
THIS IS SO COOOOOL OMIGOD
This is the sort of shit I always wondered about when I first found out about black holes and some of the introductory physics related to them, it’s so crazy awesome that this is legit SCIENCE
9:40 That Okay was the most "oh, you're doing "science" again, don't you?" answer.
A black hole is like a ball of darkness that pulls in everything and everyone
From the point of view of external observers, nothing ever crosses the event horizon. Black holes are hollow shells. All the mass is at the event horizon or outside it.
Love the video. Hate BetterHelp and their unsolicited selling of user information to advertisers.
Very well done. Many thanks.
Not a balck real hole. In case anyone wondered. Its just black in the case of no escaped light. And an explanation of the point of no return for a black hole
From the outside, doesn't the star freeze in time and never actually become a proper black hole, due the same time dilation effects that you were talking about in the video? If so, then the density is not infinite, but is actually smaller then the density of air for supermassive black holes. It only possibly gets larger in the falling frame.
This is demonstrating my mood. I’m falling and I cannot stop it from happening. It’s too wide to grab another edge and there’s no-one nearby to save me. The therapists just don’t get it.
Falling into a black hole? Isn't this Stargaze's thing, falling into planets and things?😁
If time "stops" at the event horizon, then nothing ever falls in, or even so slowly that the black hole evaporates before that.
If from an external point of view nothing ever "finish falling" into a black hole, how can they be growing in size (also from an external point of view), without having ever trully "swallowed" anything?
If you fell feet first into a black hole would you be able to see your feet? Would light be able to make it from your feet to your eyes?

5:25 you look like you took masterclasses from Kazuo Ôno so well done
3:07. This is not accurate. As you approach the event horizon, the black hole would appear as a disc in front of you growing larger and larger. The moment you reach the event horizon, the disc would appear infinitely large, equivalent to a plane, so now the universe would appear cut in half, stars on one side of the plane, darkness on the other. Once you pass the event horizon, the visible universe would shrink into a disc that would become smaller and smaller as you near the singularity. You’d see that disc by looking away from the singularity. Essentially the singularity would envelope your entire view forward and back, with the visible universe shrinking to a point behind you. So you would be able to notice right when you cross the event horizon. That’s the moment the event horizon appears as a plane. You can see that in the app by adjusting your view lateral to the event horizon and positioning yourself directly at it.
I have a question. If light can't escape a black hole due to gravity, how much influence do other objects have on light? Like the moon would be miniscule, Earth would likely be similar, but what about the sun or bigger stars? Do objects shift the light we see? And if so, does that mean other galaxies and stars far away are not really in the direction we are looking, and has their light been shifted from gravity like some sort of mirror maze?
Yes. This is called "gavitational lens".
@dirceuh that's awesome. So, theoretically, if we could space travel, just getting direction would be an insane amount of math! He should do a video on that.
best example of this I've seen in a while
KAM ARIS says it best: "The significance of the passage of time, right? The significance of the passage of time. So when you think about it, there is great significance to the passage of time...there is such great significance to the passage of time."
I just love your dry humor 😂
Anyway, when an outside observer (say Alice) sees someone falling in (say Bob) slowing down, shouldn't Alice also see Bob becoming bigger?
When Bob brings Einsteins light clock, Alice would see it ticks slower. But since light moves at the same speed for all observers, the distance between the mirrors of the light clock must become really big to accommodate for the slow ticks. So Alice also sees Bob smear out over the horizon.
But for Bob the light clock would retain its original size. But the light clocks that already were near the horizon, seen from Bob, they would shrink again then. Since this counts for everything near the horizon, the whole thing shrinks. Until it becomes really really small, like a dot. The singularity?
So conclusion: the horizon is the singularity. 😜 The difference is just the perspective.
Unfortunately everyone explaining "what it would look like falling into a black hole" forgets one important fact: Humans cant withstand acceleration above a certain point, but the closer you get to a black hole the faster you move. So in reality, youd be dead long before you reach it. The Schwarzschild Radius already accelerates at the speed of light. Once you reach the point of 5 G and above, its over. Doesnt matter the suite or ship.
We don't know whether a singularity exists at the center of a black hole, because we don't know whether our mathematical understanding of black holes actually describes what is under the event horizon, and we don't know whether points mathematically defined as being inside the event horizon even correspond to anything in physical reality.
What we DO have observational testing of, though, is the approximate relation of a black hole's mass to its radius, because we have images of the accretion disks of Sagittarius A* (the Milky Way supermassive black hole) and the M87 supermassive black hole, and thus of the regions of these disks blocked out by the black holes. And this relation dictates that the average density (not considering what if anything is inside the event horizon) goes down as the mass increases, because the event horizon radius increases linearly with the mass, which means that the volume increases with the cube of the mass.
taking into account time dilation, if conditions are appropriate (speed, angle, black hole size, etc.) could you orbit a black hole just after crossing the event horizon for long enough that the black hole has a chance to evaporate and shrink around you making you exit the event horizon again eons in the future?
That dedication to use that much fabric as a prop circle
That ending…I would question my dad😂
Just a quick reply... No paradox just poor explanation. When your clock slows down there's nothing that happens to your velocity. If anything you feel like your velocity is increasing because you're going so much further in just a few ticks. When you get close to the black hole and only one millisecond passes for each real second then you have like no time to observe that you're falling towards the singularity it's not infinite time. But not only do you get time dilation from the gravitational well but you also get time dilation from your speed. So in the time you can do something in a millisecond it takes you a real second to do that action. So before you could snap the shutter on your camera *floop* and you're already in the event horizon.

Hi Action Lab dude.. I have a decent idea for an experiment. I never really know where is best to contact you so I'll type it out here... (how is it best to send you ideas? I often think them up...) Ok here goes..
The doppler effect. You know that old experiment where an open train goes by at a moderate speed and there are musicians stood on it all playing a single trumpet note. Then of course the observer hears that classic lowering of the tone as the train goes by... What I need to know is... is it at all possible to have them play a "reciprocal " rising note as they go by and therefore cancel out the audible doppler effect? So the witnesses just hear a single stable tone as the train hoes by?
I can't quite decide if it will work or not. I can imagine the doppler effect sneaking in anyway in some way.... Obviously the effect would only be available to hear stood right next to the witness. I'm kinda 50/50 on it So I'd love to see it tested!
Also, a little extra on the doppler effect... I discovered this from picking up my boomerangs off the ground. When there's a a plane going over and its roughly above you, bend down to touch the ground slowly and then back up. Youll find you hear a doppler effect! Even though the plane is a couple of miles away and you are only changing the distance by three feet, that plane is also going really fast so the distance is a lot more than than it seems at first glance.... Anyway I hope you see this, I love your videos so keep up the good work! Kind regards, Ryan ;)
Huge thanks. This gonna give me ability to bring insane content about keeping our loved ones in the same "sphere of influence" haha. Golden sir. Channel never disappoints.
i can imagine this fabric would heat up by a lot because it's so black it absorbs 99.9% of the sun's energy
So if we could somehow send 1000 stars simultaneously into a black hole, we would never see them enter, right? So how do supermassive black holes actually form if relative to us, nothing actually falls in them? Would we observe the mass of the singularity to increase in my example? If so, WHEN would the singularity grow in mass?
The shadow of a whirl pool on the bottom of a pool is the perfect example of a black whole.
Notice it says giant, not supergiant. Lol
So if we developed the technology to hover above a black whole we could literally time travel
I hope you all realize that although he speaks in absolutes, as if this is factual, it is just theoretical. No one knows if any of this is true. Enjoy the entertainment value of this.
Due to the two dimensional surface analogy, I was expecting the cartoon animation to show an astronaut approaching the black hole sideways instead of vertically
Your videos keep me from falling into the black hole of my life.
nobody talks about this black hole on the field wouldn't be black at all, but because bending the light from the opposite side it would be invisible in a sense, distorting the image you see highly.
This is the thing that kills me: If, to the external observer, it takes forever for the infalling matter to reach the event horizon, is that just an optical illusion or can the black hole actually never consume matter as far as an external observer is concerned? Because if that's the case, how can a black hole grow?
From an outside observer's perspective, wouldn't the black hole die before the person reaches the event horizon?
Damn, that's actually even more scary! Imagine seeing your friend freeze and just slowly disappear as if he was just an illusion all the time!
"they can't even agree on the order events happen". While this is technically true, it's important to mention that everyone always agrees on the order that causally related events happen (i.e. any two events within each others' future or past light cones).
